Abstract
Mycobacterium paratuberculosis was isolated from the uterine flush fluids obtained from 3 to 4 cows with clinical paratuberculosis. Four cows with clinical paratuberculosis were subjected to uterine lavage, using an established embryo recovery technique, and the recovered fluids were cultured for M paratuberculosis. Mycobacterium paratuberculosis has previously been demonstrated to adhere to bovine ova. Embryos within the uterus of a superovulated cow infected with M paratuberculosis could be exposed to the organism.

Abstract
Intrauterine infection of murine encephalomyelitis virus GDVII was investigated by the indirect immunofluorescence method. Sixty-day-old pregnant mice were inoculated with 5 gradated doses of the virus ranging from 0.001 to 1.5 MLD50 via i.v. route on the 10th day of gestation. The mice exsanguinated on postinfection day 8 showed high incidences of viral antigen in the uterine walls, placentas, and fetal subcutaneous tissues with doses of 0.1-1.5 MLD50, regardless of the presence of maternal symptoms. Incidence of viral antigen-positive cells in fetal brains was high with a dose of 0.1 MLD50, but not by the other doses. However, the brains of the stillborn and newly-born mice derived from females infected by a dose of 0.5 MLD50 brought about still higher detection rates of viral antigen, as well as in the postpartum uteri. In effect, transplacental transmission of the virus was clearly demonstrated, and appeared to be dose-dependent.

Abstract
Serologic evidence indicated that an episode of congenital abnormalities in sheep was caused by Cache Valley virus (CVV), a bunyavirus indigenous to the United States. To determine the teratogenic potential of CVV in sheep, fetuses were infected in utero between 27 and 54 days of gestation with an isolate (CK-102) obtained in 1987 from a sentinel sheep in San Angelo, Texas. The dams of these fetuses were euthanatized between 28 and 75 days after inoculation, and the fetuses were examined for malformations. Twenty-eight of 34 fetuses had congenital abnormalities, including arthrogryposis, hydranencephaly, mummification, reabsorption, and oligohydroamnion. Virus was isolated from the allantoic fluid of 11 of 17 fetuses euthanatized at less than 70 days of gestation. The virus-positive fetuses, which were all negative for CVV-neutralizing antibody, had lesions ranging from none to severe arthrogryposis and hydranencephaly. Virus was not recovered from the allantoic fluid of fetuses after 76 days' gestation when CVV-specific antibody could be detected in 5 of 8 fetuses examined. The 2 fetuses infected on days 50 and 54 of gestation appeared normal and 1 had antibody to CVV.

Abstract
A gram-variable pleomorphic bacillus was isolated from the reproductive tracts of 4 mares during routine prebreeding soundness examinations. Using a commercial bacterial identification system, these organisms were identified as Streptococcus acidominimus. However, colonial and Gram-staining characteristics did not support this identification. Subsequent testing indicated the organism was similar to Gardnerella vaginalis. Additional growth and biochemical analysis performed in our laboratory and at the Michigan Department of Public Health and by the Center for Disease Control, Atlanta, Georgia, confirmed the identification of G. vaginalis.

Abstract
Bacterial culturing was conducted on samples from the reproductive tracts of 53 clinically healthy female cats. Aerobic bacteria were isolated from 52 of 53 vaginal swab samples and from 2 of 29 uterine swab samples. Anaerobic bacteria were detected in 4 of 30 vaginal and 1 of 29 uterine cultures. The aerobic bacteria included species of Acinetobacter, Actinomyces, Corynebacterium, Escherichia, Haemophilus, Klebsiella, Lactobacillus, Staphylococcus, and Streptococcus. Coagulase-negative Staphylococcus, Streptococcus canis, and E coli were the most common organisms and were isolated from 56%, 52%, and 44% of the vaginal samples, respectively. Anaerobes isolated from vaginal samples included 3 species of Bacteroides and 2 isolates of Peptococcus. The single uterine anaerobe isolate was a Lactobacillus sp. The number of bacterial species isolated from each vaginal culture ranged from 1 to 8 (mean, 3). The number of colony forming units tended to vary inversely with the number of bacterial species detected in each sample.

Abstract
The relationship between indigenous bacterial floras in the lower genitals and the uterocervical region is of importance due to a barrier-like role against ascending infections through the mechanism of the localized protection at a boundary of the uterocervical region. Therefore, bacterial flora in the uterocervical and uterine regions was studied in cases for which gynecological operations were performed (n = 77). 1. Ratios of incidences of the detection of bacteria on the uterocervical and in the uterine regions were 50/77 (64.9%) and 6/77 (7.8%), respectively. When different age groups are compared, the detection ratio from the uterocervical region was high among patients in the 40 s, and all the cases in which bacteria were detected from the uterine region were in the 40 s. 2. Gram-positive bacteria were detected at a high ratio, and anaerobic bacteria were noted in the uterocervical region, and ratios of detection of Staphylococcus epidermidis, Lactobacillus sp. and Propionibacterium acnes were high. Six strains of Gram-positive bacteria and 1 strain of Candida sp. were noted in the uterine region. 3. When cefmetazole (CMZ) was administered for the prevention of the infections after these panhysterectomy cases examined here, no postoperative infectious diseases nor adverse reactions were noted.

Abstract
Effects of sialodacryoadenitis virus infection on the reproduction of female SHR rats were studied. The oestrous cycle was considerably perturbed in most infected rats, the perturbation was observed initially between Days 0 to 10 post infection and the effect persisted for 6 to 18 days. About half of the foetuses of dams infected on Day 0 of gestation were found dead while only 4% of the foetuses from non-infected dams were found dead. Five or six days after infection on Day 0 of gestation, some infected dams were shown to have metritis, and virus antigen was detectable within the endometrium as well as exudate cells. In dams infected on Day 5 or later of gestation and severely diseased, the offspring showed a low survival rate possibly because of inadequate nursing.

Abstract
A 2-year study was conducted to determine the incidence of Pasteurellaceae in abortion samples submitted for diagnostic evaluation. A total of 687 cases, including 623 with fetal tissues and/or stomach contents and 302 with placenta and/or uterine discharge, were evaluated. Pasteurellaceae were isolated on a nonselective medium from 9 (1.5%), 14 (2.8%), 13 (12.1%), and 42 (17.4%) of the fetal tissues, stomach contents, uterine discharges, and placentas, respectively. A total of 35 (19.9%) of 176 placental samples cultured on both a selective medium for Pasteurellaceae and a nonselective medium were positive for Pasteurellaceae. Fifteen (42.9%) of these isolates were detected only on the selective medium, whereas 5 (14.2%) were detected only on the nonselective medium and 15 (42.9%) grew on both media. Placentitis of different severity was evident in 13 (68.4%) of the 19 placentas from which Pasteurellaceae were isolated in the absence of other known abortifacient agents.

Abstract
The author tested ways of collection, transport and storage of material for mycoplasmatological examination. The use of tampons on a stick during transport in urea substrate medium proved useful. The site of maximum occurrence of mycoplasmas was the posterior vaginal vault. On examination of the vaginal secretion of 804 women Mycoplasma hominis was isolated in 29.6% and Ureaplasma urealyticum in 65.2% of the cases. Concurrent isolation of Mycoplasma hominis and Ureaplasma urealyticum was recorded in 22.1% of the women. The results of the examination do not suggest the participation of mycoplasmas in the development of aminocolpitis. In pregnant women there is a greater probability of colonization of the vagina by U. urealyticum.

Abstract
The mean survival age of female AKR/J mice was significantly prolonged, the enlargement of thymus was markedly suppressed, and the proliferation of ecotropic and recombinant murine leukemia viruses was inhibited when 2-month-old female AKR/J mice were injected intraperitoneally with attenuated Streptococcus pyogenes, strain Su (OK-432) twice weekly for 8 weeks. However, these effects of OK-432 in 2-month-old female AKR/J mice were not seen in 5-month-old female AKR/J mice. The difference in the effectiveness of OK-432 in these animals probably depends on the difference in the degree of the proliferation of ecotropic and recombinant murine leukemia viruses in the thymus which consequently lead to thymic lymphoma.

Abstract
The potential for cervicovaginal contamination has precluded direct sampling of the endometrial cavity and has led to the development of multi-lumen protected catheter systems, among other techniques. The extent of this presumed contamination was examined using three different techniques in 55 postpartum women with the diagnosis of endometritis. Each woman had the endometrium sampled with an unprotected cotton-tipped swab, a double-lumen catheter with brush, and a flexible endometrial suction curette. A statistically larger number of bacterial species was recovered with the cotton swab (2.4) than with the double-lumen catheter (1.3) or the suction curette (1.7) (P less than .001). A difference was also noted between the double-lumen catheter and the suction curette (P = .006); however, this represented less than one-third of a single bacterial species. The larger number of bacterial species recovered by the unprotected methods was found to result not from cervicovaginal contamination, as suspected, but from a significant increase in the recovery of bacteria commonly regarded as potential pathogens, such as Bacteroides bivius, Streptococcus faecalis, Proteus mirabilis, and Bacteroides melaninogenicus.

Abstract
Uterine response to inoculation with Streptococcus zooepidemicus organisms, 51Cr-labeled 15-microns microspheres, and charcoal was evaluated in 9 mares (4 resistant and 5 susceptible to endometritis) to determine mechanical and cellular clearance rates during the early postovulatory period. Mares were inoculated at estrus prior to ovulation during estrous cycles 1, 3, and 5. Uterine swab specimens for aerobic and anaerobic bacteriologic culture and serum for progesterone determination were obtained on postovulation day 3 during estrous cycle 1, on the day of ovulation during estrous cycle 3, and on postovulation day 5 during estrous cycle 5. Immediately thereafter, the uterus was irrigated with 50 ml of sterile physiologic saline solution containing tracer amounts of 125I-labeled human serum albumin. Streptococcus zooepidemicus was isolated from 10 of 15 (67%) uterine specimens collected from susceptible mares and incubated aerobically. Escherichia coli also was isolated from 2 of the 10 specimens incubated aerobically. Anaerobic bacteriologic culture of specimens from all mares yielded no growth. Chromium-labeled microspheres were recovered twice from 2 susceptible mares, on day 0 and day 5. Charcoal was retained in 5 specimens collected from 3 susceptible mares. Bacteriologic culture of specimens from resistant mares did not yield growth. On day 0, chromium-labeled microspheres and charcoal were recovered once from 1 resistant mare. Mares susceptible to endometritis accumulated more fluid within the uterine lumen after ovulation than did resistant mares (mean +/- SEM, 52.73 +/- 15.22 ml and 7.41 +/- 1.96 ml, respectively; P less than 0.01). From this study, it appeared that uterine cellular and bactericidal mechanisms are dysfunctional during the early postovulatory period. However, there appeared to be no disruption of the mechanisms responsible for mechanical clearance of materials inoculated in the uterus.

Abstract
As the result of the study carried out by the authors, a conclusion has been made on the leading role of polymicrobial aerobic-anaerobic complexes, capable of producing a synergic effect, in the etiology of endometritis, anaerobic microorganisms prevailing in their importance. In the etiology of endometritis the most important organisms are bacteroids and peptostreptococci among anaerobes, enterobacteria and group D streptococci among aerobes. Anaerobic bacteria causing endometritis are most sensitive to dalacin and lincomycin, least sensitive to benzylpenicillin, resistant to aminoglycosides. The amounts of aerobic and anaerobic microflora contaminating the uterine cavity correlate with the severity of endometritis.

Abstract
In a prospective study, 519 women were randomly selected for cervical dilatation by laminaria tents or Hegar dilators before scheduled vacuum aspiration. In other 68 women randomly divided into a laminaria group and a control (Hegar) group, placenta, decidua and blood were separately aspirated from the uterine cavity before the vacuum aspiration and cultured for micro-organisms. The rate of postabortal inflammatory disease (PID) was significantly lower after pretreatment with laminaria tent irrespective of patient's age and parity. However, a higher risk of postabortal PID was found in gestational age of 10-12 weeks than of 5-9 weeks. Previous PID and abortion did not increase the risk of postabortal PID. Vaginal/cervical micro-organisms were, irrespective of method for cervical dilatation, identified in two thirds of the patients.

Abstract
Swab specimens for bacterial culture were obtained from the uterus, vagina, vestibule, and clitoral fossa of 48 mares that had normal reproductive tracts, no history of reproductive problems, and no inflammation on evaluation of endometrial biopsy. The mares were predominantly Thoroughbred and Standardbred. Swab specimens of the vagina were obtained through a sterile speculum; swab specimens of the uterus were obtained by use of a double-guarded, occluded culture instrument. Fifteen (31%) of the uterine swab specimens and 20 (42%) of the vaginal swab specimens yielded growth on aerobic culture; however, only 2 (4%) of the uterine swab specimens and 4 (8%) of the vaginal swab specimens yielded growth of more than 10 colonies. In contrast, 21 (44%) of the vestibular swab specimens and 45 (94%) of the clitoral fossa swab specimens had moderate (greater than 10 colonies in 1 quadrant) to heavy (colonies in 2 or 3 quadrants) growth of organisms on culture. Of organisms considered to be potential pathogens, Streptococcus zooepidemicus and Escherichia coli were found on bacteriologic culture of several clitoral fossa swab specimens and of some vestibular swab specimens. We did not isolate any potential pathogens from uterine or vaginal swab specimens. It appears that 1 to 10 colonies of nonpathogenic organisms could be recovered from the uterus in a substantial number of clinically normal mares even when double-guarded swabbing techniques are used, and we suggest that prebreeding culture requirements be modified to reflect this. Also, our findings indicate that the vulvovaginal fold, rather than the cervix, might be the major barrier to ascending bacterial contamination of the reproductive tract.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A previous study demonstrated that mouse uterine horns contained bacteria of several species on the morning after mating, and immunolabeling showed that many of these bacteria were coated with immunoglobulins. In the present study we used an ELISA technique to detect naturally-occurring antibodies against bacteria in mouse uterine luminal fluid, vaginal washings and serum. Each fluid contained specific IgA and/or IgG antibodies to five of the six bacterial species recovered from the uterus after mating. The uterine fluid antibodies that bound to the bacteria were mainly IgA molecules, while those in the serum were mainly IgG. Naturally-occurring bacterial antibodies in mouse uterine luminal fluid may play a role in protecting the endometrium against microbial infections.

Abstract
A previous study demonstrated that several species of bacteria were present in the mouse uterine lumen on the day after mating, and that many of these bacteria had immunoglobulins bound to their surface. Neutrophilic leukocytes containing phagocytosed bacteria were also present in the lumen. Since bacteria are phagocytosed efficiently only when they are opsonized by the binding of specific antibody or C3b or both to their surface, we investigated whether the uterine bacteria were coated with C3. Immunolabeling demonstrated that an antigenic portion of C3, possibly C3b, was bound to many of the uterine bacteria. This observation suggests that bacteria in the mouse uterus after mating may be opsonized by both antibody and complement and that phagocytosis of these bacteria by neutrophils may play an important role in returning the uterus to an aseptic state before implantation.
