Transmission by Contact via Feces, urine or Tick-excretes
- can Borrelia burgdorferi enter through intact mucous membranes?
Unusual features in the epidemiology of Lyme borreliosis.
Eur J Epidemiol 1996 Feb; 12(1): 9-11 PMID: 8817171
In this study two cases of Lyme borreliosis are presented. First, the author describes how he contracted Lyme borreliosis 24 hours after he visited an endemic area. The second case described is that of a woman who developed Lyme borreliosis symptoms, when intestinal content of an infected tick came into contact with her conjunctiva. In both cases the diagnosis is based on clinical picture and positive serological tests. The first case shows the probability of contracting Lyme borreliosis when the duration of the tick's attachment to the skin is less than 24 hours. The second case, described demonstrates transmission of B. burgdorferi by contact.
Apart from the two cases mentioned in the abstract the author tells about two other cases of direct transmission, he'd heard of:
1. 1989 Prag conference - a laboratory worker, during handling of a tick, the tick dropped onto a hot lamp. The tick bursted and the intestinal material hit the eye of the lab worker, who developed conjunctivitis and positive borrelia serology.

Experimental inoculation of dogs with Borrelia burgdorferi.
Zentralbl Bakteriol Mikrobiol Hyg A 1986 Dec; 263(1-2): 49-54 PMID: 3554844
To determine if dogs could serve as a reservoir for Borrelia burgdorferi, three beagles were inoculated subcutaneously (SQ) with 200 laboratory cultured spirochetes which were originally isolated from blood of a Peromyscus leucopus from
Clinical and serologic evaluations of induced Borrelia burgdorferi
infection in dogs.

Am J Vet Res 1988 Jun; 49(6): 752-7 PMID: 3041881
Adult Beagles were used to evaluate clinical signs and serologic response after inoculation with, or exposure to, Borrelia burgdorferi. An indirect immunofluorescent assay (IFA) and 2 ELISA were used to monitor the serologic response to B burgdorferi. Feeding infected ticks on 4 dogs (group 1) failed to cause seroconversion, and SC inoculation with 500 organisms caused minimal seroconversion in 2 of 4 dogs (group 2). At 56 days, approximately 3.01 X 10(8) B burgdorferi organisms were injected IV into group-1 dogs, and intraperitoneally into group-2 dogs. A control group of 4 dogs (group 3) had noninfected ticks feed on them, and then were given IV injection of physiologic saline solution. Increases in immunoglobulin M (IgM) titers were detected in 2 of 4 group-2 dogs approximately 7 days after the initial exposure. These titers returned to negligible values 20 days later. Immunoglobulin G titers increased approximately 10 days after the initial exposure and were mildly increased 56 days later, when dogs were exposed a second time. Both the IV and intraperitoneal injections (second exposures) resulted in increased IgM titers, which in both groups eventually returned to preexposure values after approximately 2 months. Immunoglobulin G titers increased within a week after the second exposure, and in 3 dogs monitored for 8 months, returned to negligible values after the 8-month period. One control dog had a slightly increased IgG titer 24 days after the second inoculation. The possibility of urine transmission is suggested. Clinical status, hemograms, serum biochemical profiles, ECG and results of urinalyses remained normal throughout the study.(ABSTRACT TRUNCATED AT 250 WORDS)
The prevalence and significance of Borrelia burgdorferi in the urine of
feral reservoir hosts.
Bosler EM, Schulze TL. Zentralbl Bakteriol Mikrobiol Hyg A 1986 Dec; 263(1-2): 40-4 PMID: 3577491
Live Borrelia burgdorferi were isolated from the blood and/or urine of white-footed mice (Peromyscus leucopus) collected on Shelter Island, New York, in 1984 and 1985. Prevalence of spirochetes in urine was consistently higher than in blood or both fluids simultaneously. Spirochetes remained viable for 18-24 hours in urine and were maintained in culture for one week. Mice removed from the field were spirocheturic for at least 13 months. One spirocheturic mouse developed spirochetemia one month after field removal indicating the pathogen can return to the peripheral circulation. Twenty-one kidneys from 22 mice had spirochetes in the interstitial areas and bridging the tubules. A positive correlation between Babesia microti infection and spirocheturia was seen. Although the mechanism of entry into the urine is unknown, B. microti infection may increase glomerular permeability. Babesia induced hematuria may provide possible nutrients to maintain spirochetes. Urine may provide a method for contact non-tick transmission of B. burgdorferi in natural rodent populations particularly during periods of nesting and/or breeding.
Transmission by MILK or food?
Most spirochetes (and other bacteria) ingested will probably be
killed by the high acidic content in the stomach, but people with
achlorhydria and newborns that have very low stomach acid production, does not
have this protective barrier and might be at increased risk for getting
infected by the oral route, if they ingest live spirochetes.
Pasteurizing the milk and never eat semi-raw meat - must be recommended as prophylaxis.
Experimental inoculation of Peromyscus spp. with Borrelia burgdorferi:
evidence of contact transmission.
Burgess EC, Amundson TE, Davis JP, Kaslow RA, Edelman R. Am J Trop Med Hyg. 1986 Mar;35(2):355-9. PMID: 3513648
In order to determine if Peromyscus spp. could become infected with the Lyme disease spirochete (Borrelia burgdorferi) by direct inoculation and to determine the duration of spirochetemia, 4 P. leucopus and 5 P. maniculatus were inoculated by the intramuscular, intraperitoneal, and subcutaneous routes with an isolate of B. burgdorferi obtained from the blood of a trapped wild P. leucopus from Camp McCoy, Wisconsin. All of the mice developed antibodies to B. burgdorferi which reached a peak indirect immunofluorescent (IFA) geometric mean antibody titer of 10 log2 21 days post-inoculation. B burgdorferi was recovered from the blood of 1 P. maniculatus 21 days post-inoculation. One uninfected Peromyscus of each species was housed in the same cage with the infected Peromyscus as a contact control. Both of the contact controls developed IFA B. burgdorferi antibodies by day 14, indicating contact infection.
To determine if B. burgdorferi was being transmitted by direct contact, 5 uninfected P. leucopus and 5 uninfected P. maniculatus were caged with 3 B. burgdorferi infected P. leucopus and 3 infected P. maniculatus, respectively. Each of these contact-exposed P. leucopus and P. maniculatus developed antibodies to B. burgdorferi, and B. burgdorferi was isolated from the blood of 1 contact-exposed P. maniculatus 42 days post-initial contact. These findings show that B. burgdorferi can be transmitted by direct contact without an arthropod vector.

Borrelia burgdorferi was identified as the etiological agent of Lyme disease in 1982. This Gram-negative spirochete is classified in the order Spirochaetales and the family Spirochaetaceae. The pathogen is fastidious, microaerophilic, mesophilic and metabolises glucose through the Embden-Meyerhof pathway. A generation time of 11 to 12 h at 37 degrees C in Barbour-Stoenner-Kelly medium has been reported. Lyme disease, named after Lyme in
Evidence for in utero Transmission of Borrelia burgdorferi from
Naturally Infected Cows
Leibstein MM, Khan MI, Bushmich SL
Journal of Spirochetal and Tick-Borne Diseases 1998; 5(4):54-62 [Not listed on PubMed]
(excerpts from the abstract: Five of 15 adult cows were spirochetemic at parturition; 4 of the calves from these cows were also spirochetemic at birth (PCR). Spirochetes were cultured from the placentas in 2 of 10 cows and from the uterine fluid in 1 of 8 cows. Borrelia burgdorferi DNA was detected in the colostrum in 4 of 12 cows. Three of 15 calves were stillborn; Borrelia burgdorferi DNA was detected by PCR in 3 of 3 and spirochetes cultured from 2 of 3 stillborn calves. Fetal tissues from which Borrelia burgdorferi DNA was detected include blood, spleen, bladder, kidney, synovial fluid and tissue, heart, cerebrum, and aqueous humor. Borrelia burgdorferi was cultured from the spleen of one stillborn calf and the kidney of another. Detection of Borrelia burgdorferi DNA from the tissues of stillborn calves, as well as spirochetemia in neonatal liveborn and stillborn calves, gives evidence for in utero transmission of Borrelia burgdorferi in naturally infected dairy cattle.)

Transmission of Borrelia burgdorferi from Experimentally Infected Mating
Pairs to Offsprings in a Murine Model.

The current literature on B. burgdorferi=s mode of transmission in animal models supports only transmission of the organism by an infected tick bite. In an effort to develop a murine model for studying other modes of transmission of B. burgdorferi, we started with the well studied C3H/HeJ mouse. Abzug et al. has shown that splenectomy increases the in utero transmission of enteroviruses in a murine model. Splenectomized 6-8 week-old mice were divided into 4 groups. Groups A, B, and C had 23, 24, and 26 mating pairs respectively.
Immediately prior to mating, in group A only females, in group B only males, and in group C both females and males were infected subcutaneously with 106-107 B. burgdorferi in 250 ml SKB II media. The control group D had 12 mating pairs in which both male and females received sterile SKB II as placebo.
The resulting pups were sacrificed at 1, 7, 14, and 21 days of age. The milk content of the stomach, sections from ear, skin, heart, liver, spleen, brain, bladder, and kidney of the 1, 7, and 14 day-old pups were cultured for B. burgdorferi. The cultures were read at 3, 6, and 9 weeks post incubation. The above mentioned tissues except milk were also cultured from sacrificed 21 day-old weanlings. Transmission to offsprings was indicated when B. burgdorferi was isolated from any tissue from a given pup.
From the experimentally infected females in which the milk was cultured (total 25 females in groups A and C), 2 (8%) transmitted B. burgdorferi to their pups on day one via their milk: 2 pups from a litter of
These results indicate that B. burgdorferi can be transmited by other modes besides the tick bite in spleenectomized mice. The described mouse model with further modifications may provide a tool for studying such transmission modes and treatment strategies.
This study has also been presented on the following conferences, but I don't have the abstracts (I any of you readers have them, please send me a copy, will you?):

Abstract # I-17
In an effort to develop a murine model for studying other modes of transmission of B. burgdorferi (Bb), we started with the well studied C3H/HeJ mouse. Splenectomized 6-8 week-old mice were divided into 4 groups. Groups A, B, and C had 23, 24, and 26 mating pairs respectively. Prior to mating, in group A <![if !vml]><![endif]>, in group B <![if !vml]><![endif]>, and in group C both <![if !vml]><![endif]> & <![if !vml]><![endif]> were infected subcutaneously with 106-107 (Bb) in 250 ml SKB II media. The control group D had 12 mating pairs in which both <![if !vml]><![endif]> & <![if !vml]><![endif]> received sterile media.
Resulting pups were sacrificed at 1, 7, 14, and 21 days of age. Milk content of the stomach, sections from ear, skin, heart, liver, spleen, brain, bladder, and kidney of the 1, 7, and 14 day-old pups were cultured for Bb. The above mentioned tissues except milk were also cultured from sacrificed 21 day-old weanlings. Transmission to offsprings was indicated when Bb was isolated from any tissue from a given pup.
From the experimentally infected <![if !vml]><![endif]> in which the milk was cultured, 2 (8%) transmitted Bb to their pups on day one via their milk. Among 49 infected <![if !vml]><![endif]>from groups A and C, 5 (10.2%) transmitted Bb to their pups either in utero or intrapartum. Four of the litters from the mating pairs in group B had infected pups. These results indicate that Bb can transmit by other modes than the tick bite. The described mouse model with further modifications may provide a tool for studying such transmission modes and treatment strategies.
Sexual transmission ?
of borreliosis in between humans have not yet been firmly proved, but is certainly a suggested possibility?!
First, take into account that the MAIN ROUTE OF TRANSMISSION for its close relative, another spirochaete, TREPONEMA PALLIDUM, which cause SYPHILIS, which is a chronic infectious illness expressing many similarities with Borreliosis, as it was noted already in 1922 by Garin & Bujadoux! – is occurring via exactly sexual transmission semen to vagina / skin to skin from one infected human to another human!
There is no known animal reservoir, only humans are infected with syphilis. Only ONE spirochaete is supposed to be enough to transmit syphilis from person to person!
Despite syphilis must be transmitted via close human to human contact, this microbe has been extremely successful in spreading all over the world and the disease has NOT YET been eradicated from the Earth, despite treatment with penicillin since the 1950’ies and huge efforts in most countries to track and treat all the infected persons!
Second, take into account that another spirochaete LEPTOSPIRA (Google search) is also well known to be directly transmitted via mucous membranes and (broken) skin and infected urine/feces of infected rodents!
Leptospirosis (including Weil disease)
Cause: Various spirochaetes of the genus Leptospira. Transmission: Infection occurs through contact between the skin (particularly skin abrasions) or mucous membranes and water, wet soil or vegetation contaminated by the urine of infected animals, notably rats. Occasionally infection may result from direct contact with urine or tissues of infected animals, or from consumption of food contaminated by the urine of infected rats. Nature of the disease: Leptospiral infections, including Weil disease, take many different clinical forms, usually with sudden onset of fever, headache, myalgia, chills, conjunctival suffusion and skin rash. The disease may progress to meningitis, haemolytic anaemia, jaundice, haemorrhagic manifestations and other complications, including hepatorenal failure. Geographical distribution: Worldwide. Most common in tropical countries. … Precautions: Avoid swimming or wading in potentially contaminated waters including canals, ponds, rivers, streams and swamps. Avoid all direct or indirect contact with rodents. Source: WHO.
Third, take into account that to semen added Borrelia burgdorferi survived deep freezing better than spermatozoa!
Viability of Borrelia burgdorferi in stored semen.
Kumi Diaka J, Harris O.
Br Vet J 1995 Mar-Apr; 151(2): 221-4 PMID: 8920118
Semen from 5 dogs, 3 bulls and 3 rams were collected … divided in 2 equal parts, BSK-H medium and B. burgdorferi added + 4 controls.
A was stored at 5 degr. C for 48 hours
B was cryopreserved in liquid nitrogen at -196 degr. C for 12 weeks
The specimens were thawed in water bath to 37 degr. C.
A drop on object glass was examined in phase contrast microscope for sperm motility and viable / motile B. burgdorferi, graded on a scale 0-3.
A significant amount of spirochetes survived cryopreservation and no significant different found between the 2 different storage methods or between the 3 animal species.
The viability of B. burgdorferi in cryopreservation was better than spermatozoa!
Fourth, take into account the following observations and a hypothesis on NON-TICK TRANSMISSION of BORRELIAE, developed through critical examination of all relevant published data:
‘Lyme disease’: ancient engine of an unrecognized borreliosis pandemic?
Harvey WT, Salvato P. Med Hypotheses. 2003 May;60(5):742-59. PMID: 12710914 PDF
Unexpectedly we have found large numbers of chronically ill Borrelia burgdorferi PCR- and seropositive patients in
, a zoonotically 'non-endemic' area. In order to understand this finding prior to sufficient data availability, we chose to examine critically currently accepted but troublesome 'Lyme disease' concepts. Our method was to analyze each foundation 'Lyme disease' premise within the context of available medical and veterinary literature, then to reconstruct the disease model consistent with the preponderance of that data. We find the present conceptualization of the illness seriously truncated, with a high likelihood of two distinct but connected forms of human B. burgdorferi infection. The yet-unrecognized form appears to have a broader clinical presentation, wider geographic distribution, and vastly greater prevalence. We conclude that 'Lyme disease' currently acknowledges only its zoonosis arm and is a limited conceptualization of a far more pervasive and unrecognized infection state that must be considered a global epidemic. Houston, Texas
“Twenty-six months ago, our practice began to test chronically ill patients with multi-system presentation for Borrelia burgdorferi (Bb) infection. Our criteria further included suspicion of protracted infection and inability to otherwise find a diagnosis. About a third of initial tests were positive via CDC Western blot criteria or serum/urine PCR; however, repeat testing eventually revealed that most are positive. We had not expected these results, as we are in
Southeastern Texas, a ‘nonendemic’ region. (The prevalence of Borrelia-infected ticks in is about 1–2%.) (3–5). Texas
Concurrently, we recognized a striking similarity in symptoms and signs of test-positive individuals to other untested patients of ours. Most fit within the presentation criteria of ‘late, disseminated Lyme disease’ but with some prominent differences. We began antibiotic treatment of all test-positive patients, and most, regardless of presentation, began noticeable improvement within 3 to 6 months.
Since no history of erythema migrans (EM) rash or illness following tick bite was reported by these patients, and most had been ill for many years with similarly ill family members, we set out to understand what we were confronting. Our experience did not match the CDC case definition or the epidemiological evidence for late ‘Lyme disease’. To resolve this conundrum, we concluded that our best initial strategy was to derive our own conclusions by careful assessment of all available relevant data.”
Marie Kroun’s comments:
Above papers at least document that there is already some evidence present for:
burgdorferi can infect humans by direct contact VIA (INTACT or BROKEN?) MUCOUS
– both through conjunctiva and possibly also gastrointestinal mucosa
There is evidence
found that Borrelia burgdorferi can be EXCRETED INTO SOME HUMAN SECRETIONS!
– Already well documented for mothers milk, especially colostrum, by more researchers.
It has yet to be investigated thoroughly whether male animals or humans with ACTIVE BORRELIOSIS excrete spirochaetae into their semen? (PubMed search for “borreli*+semen*”)
If the reader know of any cases where animal or human SEMEN was investigated and found positive by culture, PCR or microscopy (+/- specific immune stain) for Borrelia burgdorferi, then please write me!
Because IN CASE Borrelia burgdorferi can be excreted into semen and be able to cross the intact or damaged vaginal membrane too, SEXUAL TRANSMISSION could be a possible way of transmission of Borrelia burgdorferi!
In above study by Sousan Altaie et al (is that the only study on this subject?), direct sexual transmission could not be demonstrated between mating pairs of splenectomized mice, i.e. sign of Borrelia infection were not present in the mother mice in group B, where only male mice were artificially infected with Borrelia by injection and whose pups became infected (personal message), but THE POSSIBILITY OF SEXUAL TRANSMISSION BETWEEN PARTNERS IS NOT EXCLUDED, just because proof of this hypothesis was not found in this study!
I think it is better to remember always that “Absence of proof is not proof of absence” and it’s “better to be safe than sorry”!
Thus MY advice to all people suspecting infectious disease – not only ACTIVE Lyme disease, but ALL SORTS OF INFECTIONS – and even to those people who are suffering from ANY CHRONIC ILLNESS of UNKNOWN CAUSE (potential infection) is:
You should always
take the necessary precautions to protect yourself and your partner and your
offspring against transmission of infections via secretions (use condoms or
avoid sex and other potentially risky close contacts)
always COOK YOUR FOOD THOROUGHLY, especially when eating wild game!
Many have over the years asked me questions about Borreliosis during pregnancy and after birth and what I would consider reasonable actions to take, in case.
I have unfortunately not yet had the time and energy to search ALL the
published literature thoroughly for the subject of “pregnancy acquired Borrelia
cases in mother and child” (PubMed
search for borreli*+pregnan*”, but I
am aware that there are a number of publications demonstrating probable and
certain maternal to foetal transmission of Borrelia infection via Google
Doherty’s review and not the least an extensive review by Gardner T in
“Infectious Disease of the Fetus and Newborn Infant, Saunders Philadelphia 1995
4th ed.; Chapter 11: 447-528”: 81 pages; 428 references reviewed, which
describes 5 previously unpublished cases of probable or proven maternal to
foetal transmission of B. burgdorferi and a review of the literature of 46
adverse outcomes of pregnancies complicated by Lyme Borreliosis!
There are a few larger epidemiological follow-up studies on Borrelia seropositive mothers, showing that the number of serologically proven transplacental transmission of symptom causing Borrelia infection in the child have been very few (i.e. these investigations generally showed a very low risk of proven Borrelia transmission to the child) and that the few symptomatic cases of congenital Borreliosis occurred in children of mothers, who acquired their Borreliosis during the pregnancy!
BUT when reading those articles please bear in mind, that there are many published papers on culture, PCR and/or microscopy proven Borrelia SERONEGATIVE cases, i.e. that absence of positive Borrelia titer in mother and/or child does NOT exclude neither an active nor a latent Borreliosis, that might not give the congenitally infected child any symptoms of Borreliosis until several months to years after birth!
More important, while a congenitally infected child might display IgM antibodies, the foetus / premature baby does not produce IgG until shortly before birth and it may NEVER develop a seropositive reaction for an infection acquired early in the pregnancy, because infections acquired during early immune system development might be seen as “part of self”, as it if it were one of the child’s own cells, i.e. immune tolerance can develop.
Seronegative infection has been observed in many types of congenital infections: congenital syphilis, congenital virus infections like CMV (1, 2), rubella and Chagas disease (Trypanosoma cruzi, just to mention a parasitosis also) and remember that people with concomitant immunodeficiency, such as agammaglobulinemia or dysgammaglobulinemia, may have a false-negative serology results for infection.
Thus negative serology does unfortunately NOT safely exclude congenital infection; on the other hand the trypanosoma paper illustrates that via placenta transmitted maternal IgG antibodies may take up to 8 months after birth to clear from the child’s blood! – so a for months persistent positive IgG antibody reaction must not be taken as sign that the baby was congenitally infected either! – this is probably true for other infections also?!
However, since IgM antibodies are too big to cross placenta, a positive IgM and rising serology titers in a newborn points to a congenitally acquired infection and thus prompts for treatment of the baby, if the infection can be treated with antibiotics – because lack of or insufficient treatment can be detrimental, as illustration in the following case!
The most famous and important - because his parents later co-founded the Lyme Disease Foundation (LDF) – congenitally acquired fatal Borreliosis case described is the son of a during pregnancy infected mother Karen Vanderhoof-Forschner and Thomas Forschner (read more here and here), Jamie Forschner (1985-1991), whose short life story is told by his mother here:
In 1990, NIH's new test that they
had developed, which is not available to the public yet, photographed the bacteria in my son despite his
repeated treatment, and not only him, but other people across the
country, showing that short-term treatment, for a few
people, may not ever work, and may not work at all. I was dismayed. When I showed this to the pediatricians, they said if we
retreated our son, based on what they got from our local health department and
our local people in the state, they would cancel us, and they canceled my son
as a patient. We had no physician in the state, and we took our son to
Once he was retreated, all his speech came back again, and for the third time he learned how to speak. Muscle tone came back, vision came back, indeed they were able to show his intelligence was very high. He was mainstreamed into kindergarten. He developed girlfriends, went to birthday parties, and we finally found a little boy inside the diseased body. We waited over one year for NIH's tests to be released. We were hoping we could use it to check on our son's progress so that he wouldn't have a relapse and die.
As my son started to relapse, I waited, and waited, and I waited too long. Our son's last relapse came on, and he started having seizures and brain infection. Within 24 hours he was dead. His brain had swelled up so much it had killed itself.
There was no tissue bank in the country to send his autopsy stuff to, so before I went down to see him and make arrangements, I picked up the phone and I called around the country and found some places that they could take the tissue and study it. One of those places was, indeed, where we couldn't find the test, at Rocky Mountain Lab at NIH. And indeed, please remember that name, because those people are wonderful, and they need your funding, more than any other area.
They took his tissue, as well as some other places in the country, and were able to document that when he died he was still infected with Lyme disease bacteria. And at some point, his report, combined with other deaths due to Lyme, combined with other children with trans-placental information, may indeed, at some time in the future, have enough peer-reviewed publications that the CDC may indeed accept trans-placental transmission or death due to Lyme, in which case public health policy can be improved.
I warmly recommend all readers to buy and read Karen Vanderhoof-Forschners book: “Everything you need to know about Lyme disease” since it contains an extensive review of all times Borrelia literature!
There are good reasons NOT to PLAN to try to get pregnant, when you have
a clinically ACTIVE chronic disease, especially one that could potentially be
caused by a known or unknown microbial infection, and hence bear a potential
risk of transmitting the disease to your child and partner!
Because there is much evidence from published case reports, that a foetus can acquire severely damaging and life-threatening Borreliosis, especially when mothers are NEWLY INFECTED with Borrelia DURING PREGNANCY, there is good reason for all pregnant women to take every precaution possible NOT to get Borreliosis (or any other infection) while being pregnant, i.e. to avoid stay in known tick habitat / tick bite and there is also good reason for treating the mother-to-be with suspected or proven Borreliosis with penicillin’s, that is a safe drug for the developing foetus, through-out the whole time of pregnancy, in the hope to be able to prevent Borrelia from spreading via placenta to the foetus! – which might not always be prevented by a conventional short term treatment usually offered for EARLY Lyme Borreliosis / erythema migrans the tell-tale (pathognomic) sign of Lyme Borreliosis !
If you are a new mother and
show signs of ACTIVE Borreliosis you should probably avoid direct breastfeeding
of your newborn baby; don’t rely on the baby’s low stomach acid level to be
high enough to kill the ingested bacteria!
In case when using formula cows milk is not an acceptable solution, like when the baby have a very high risk of developing cows milk allergy (double disposition) then if possible use donor milk from a healthy donor, or, since Borrelia burgdorferi (and syphilis) is very heat sensitive, pasteurized mothers milk (heated to 45 degr. C) should be safer food for your baby than raw milk!
