[Recurrent vaginitis and cystitis due to a vagina and cervix duplex in a bitch - a case report]. / Rezidivierende Vaginitis und Zystitis aufgrund einer Vagina und Zervix duplex bei einer Hündin ­ ein Fallbericht.

Incomplete merging of the Müllerian ducts may result in vaginal septa or even completely separate vaginal canals. It may also cause cervical malformation. In most cases, there are only rudimentary vaginal septations. Only a few reports describing completely separated vaginal canals (vagina duplex) and a cervix duplex in dogs have been published. This article reports the case of a bitch presented with recurrent vaginitis and cystitis. The symptoms always appeared following the dog's heat. The bitch had been pre-treated by a prior veterinarian as well as in a prior clinic. When presented in the clinic, a vaginal septum was suspected based on digital vaginal examination. Ultrasonographic examination and urinalysis allowed for the diagnosis of bacterial cystitis, which was subsequently treated with antibiotics. The bitch was presented again for vaginal endoscopy, transection of the vaginal septum, and ovariohysterectomy. Both vagina duplex and cervix duplex were diagnosed. Due to the extensive dimensions of the findings, the altered tissue was not resected. No more bacteria were detected in a repeated urine analysis. After spaying, the bitch showed no recurrence of symptoms of cystitis or vaginitis.

Antibiotic Susceptibility Profile of Bacteria Causing Aerobic Vaginitis in Women in Iraq.

Aerobic vaginitis (AV) is a vaginal infectious condition characterized by abnormal vaginal discharge, high inflammatory response, signs of epithelial atrophy, an increase in aerobic bacteria of intestinal origin and a decrease in the normal flora, especially Lactobacillus spp.. It is one of the most common reproductive tract infections among women. This study aimed to analyze the antimicrobial susceptibility levels of the dominant bacterial species found in the vaginae of women infected with AV. A total of 89 high vaginal swabs (HVS) were collected from women aged (18-50) years old attending some hospitals and private gynaecology clinics in Baghdad City. All obtained swabs were cultured on different culture media, and the primary diagnosis was performed according to standard laboratory diagnosis protocols. To confirm the diagnosis and to determine the antibiotic susceptibility profile of bacterial isolates, VITEK 2 Compact Automated System GP and GN colourimetric identification cards and AST GN and AST GP cards were used according to Manufacturer Company constructions (BioMérieux / France). Out of 89swabs, ninety-five pathogenic strains were obtained, including 62 isolates (65.2%), Grampositive and 33 isolates (34.7%), Gram-negative bacteria. Staphylococcus spp. (46.3%) The most represented active strain was Escherichia coli (15.7%). All Gram-positive bacterial strains displayed the highest resistance rates (100%) toward penicillins and cephalosporins, while the highest sensitivity rates were toward daptomycin, followed by vancomycin and gentamicin (P=0.001). Gram-negative bacteria displayed the highest resistance rates toward penicillins, beta-lactam combination, monobactam and cephalosporins, while the highest sensitivity rates were toward amikacin followed by imipenem meropenem and gentamicin (P=0.001). It is worth mentioning that Gram-positive bacteria showed 100% sensitivity toward tigecycline. Thirty-eight (40 %) of all obtained bacterial strains were extensively drug-resistant XDR, 57 (60%) were multidrug resistance MDR and no pan-drug resistance PDR was reported. Gram-positive bacteria include 21% XDR and 44.2% MDR strains, while Gram-negative bacteria include 18.9% XDR and 15.7% MDR strains.

Impact of a progesterone-releasing intravaginal device and inflammatory reaction on ovarian activity in embryo-recipient anestrus mares.

This study aimed to correlate the inflammatory reaction (IR) caused by a progesterone-releasing intravaginal device (P4) with ovarian activity and pregnancy rate (PR) in embryo-recipient anestrus mares (to decrease the spring transitional period). 50 animals were assigned to three groups: GP4 (P4 group; n = 16), GP4OH (P4 + oxytetracycline hydrochloride and hydrocortisone sprayed onto the device; n = 14), and GNP4 (no intravaginal P4; n = 20). The administration protocol for GP4 was: Day 0, 750 mg P4 + ovarian examination by ultrasonography (US) + vaginal sample collection; Day 8, US; Day 11, P4 removal + 7.5 mg PGF2α + US + second vaginal sample collection; Days 13 to 16, US; Days 17 to 21, US + 750 IU hCG to mares with follicles 35 mm or more in diameter; Days 19 to 23 US (ovulation check); Days 24 to 28, embryo transfer + intravenous flunixin meglumine; and Days 30, US pregnancy diagnosis. The GP4OH and GNP4 mares received the same administration protocol as GP4, except that no P4 device was administered to the GNP4 group on Day 0. Although neutrophil-mediated IR occurred in the GP4 and GP4OH groups, the IR was significantly reduced in GP4OH as compared with that in GP4 (P < 0.0001). From Day 0 to Day 17, the GP4 and GP4OH mares developed a greater number of follicles per animal than did the GNP4 mares (P < 0.05), and the average diameter of the follicles was larger in the GP4 and GP4OH mares. The ovulation rates in GP4, GP4OH, and GNP4 mares were, respectively, 43.7%, 64.3%, and 30.0%, and ovulation occurred at 6.8, 6.5, and 23 days after P4 removal (P < 0.05). On Day 17, endometrial edema was verified in 50%, 64.2%, and 35.0% of the GP4, GP4OH, and GNP4 mares, and the PRs after embryo transfer were 80%, 100%, and 66.6%, respectively. Although intravaginal devices caused IR in both the device-recipient groups (P = 0.0001), IR and vaginitis had no negative impact on follicle diameter, ovulation rate, period to ovulation after the removal of P4, endometrial edema, or PR. In addition, P4 reactivated the ovarian function and the IR eliminated a large percentage of bacteria (Bacillus spp., Enterobacter spp., Proteus spp., Pseudomonas spp., and Staphylococcus spp.), especially in GP4; the application of oxytetracycline hydrochloride and hydrocortisone on the devices reduced the severity of vaginitis.

Vaginal microbial communities from synchronized heifers and cows with reproductive disorders.

AIM: To evaluate changes in the resident microbial population in the cranial vaginal mucosa induced by a progesterone-releasing intravaginal device (PRID) compared to the vaginal microbiota of cows with reproductive disorders. METHODS AND RESULTS: Vaginal discharge was evaluated by clinical examination and a Vaginitis Diagnosis Score was performed by exfoliative cytology. All samples classified as positive and some classified as negative by clinical evaluation were later diagnosed as positive for vaginitis by cytological analysis. Bacterial diversity profiles were performed by PCR-DGGE and clustered according to the reproductive health status of the specimens, revealing a correspondence between the structures of the communities in the vagina and the clinical profile. Representative bands from each group were sequenced and identified as Ruminococcus sp., Dialister sp., Escherichia sp./Shigella sp., Virgibacillus sp., Campylobacter sp., Helcoccoccus sp., Staphylococcus sp., Bacillus sp., Actinopolymorpha sp., Exiguobacterium sp., Haemophilus sp./Histophilus sp., Aeribacillus sp., Porphyromonas sp., Lactobacillus sp. and Clostridium sp. CONCLUSION: Our results contribute to the knowledge of the vaginal microbiome in synchronized heifers showing positive or negative clinical vaginitis. SIGNIFICANCE AND IMPACT OF THE STUDY: This study contributes to the understanding of a dynamic vaginal colonization by bacterial consortiums during the synchronization with a widely used PRID protocol. Also, the results reveal the presence of well-known metritis-related pathogens as well as emerging uterine opportunistic pathogens. The provided information will allow to carry out further studies to elucidate functional roles of these native micro-organisms in the bovine reproductive tract.

Alpha and gamma herpesvirus detection in two herds of farmed red deer (Cervus elaphus) in New Zealand.

CASE HISTORY: In September 2004 two hinds on Farm 1 were observed with epiphora and keratoconjunctivitis, and corneal scarring. A low pregnancy rate in some hinds had been recorded that year. In the same year six yearling deer were observed on Farm 2 with keratitis, uveitis and corneal scarring. CLINICAL AND PATHOLOGICAL FINDINGS: On Farm 1, conjunctival swabs and blood samples were collected from the hinds with ocular lesions, and from 24 other hinds. The two affected hinds were immunosuppressed with dexamethasone for 7 days. Conjunctival, nasal and vaginal swabs were collected daily before euthanasia and necropsy on the eighth day. Subsequently, another five non-pregnant hinds were similarly immunosuppressed and necropsied, and the reproductive tracts of 20 non-pregnant hinds were collected following slaughter. Semen samples were collected from four stags implicated with reproductive failure. On Farm 2, conjunctival swabs were collected from six hinds with ocular lesions and from 14 unaffected deer. Viral culture, consensus primer PCR and sequencing for specific herpesviruses was carried out on conjunctival swabs, buffy coat from blood samples, semen and reproductive tracts. Necropsy samples were also examined using gross pathology and histopathology. On Farm 1, a type 2 rhadinovirus (CvRhV) was detected in the conjunctiva of one hind with keratoconjunctivitis using PCR. Following immunosuppression, gross vesicular and histological vaginal lesions typical of infection with alphaherpesvirus were observed in samples of vaginal tissue from the same hind. Buffy coat, vaginal and lumbar spinal nervous tissues were also positive for cervid herpesvirus 1 (CvHV-1) using PCR. Herpesviruses were not detected in reproductive tracts, ocular or semen samples of the other deer. CvRhV was detected in buffy coats from four other hinds and in a conjunctival swab from one hind, all without ocular lesions, using PCR. On Farm 2, conjunctival swabs from two deer with keratitis were culture positive for CvHV-1. Two culture-negative conjunctival samples from deer without ocular lesions were positive for CvHV-1 by PCR. In two other affected animals, presence of CvRhV was confirmed by PCR and sequencing. DIAGNOSIS: Infection with CvHV-1 associated with keratitis and vulvovaginitis, and CvRhV infection in deer with and without ocular lesions. CLINICAL RELEVANCE: CvHV-1 is a likely cause of keratoconjunctivitis and possibly reproductive tract pathology in deer. Investigation of ocular lesions and reproductive failure in farmed deer should include CvRhV and CvHV-1.

In captive rhesus macaques, cervicovaginal inflammation is common but not associated with the stable polymicrobial microbiome.

Vaginal inoculation of rhesus macaques (RM) with simian immunodeficiency virus (SIV) has been used to study the biology of HIV transmission. Although the results of vaginal SIV transmission experiments could be affected by vaginal inflammation, studies to date have been conducted without regard to levels of pre-existing genital inflammation present in RM. We collected cevicovaginal secretions (CVS) from 33-36 RM during the mid menstrual cycle (day 10-20) at 2 time points approximately 8 months apart and characterized the mRNA and protein levels of inflammatory cytokines, chemokines and interferon-stimulated genes. There was extreme variability in the levels of inflammatory mediators (IFN-α, IFN-γ, IL-6, TNF, IL-1b, IP-10, MIG, IL-12 and IL-17). In most animals, the mRNA levels of the inflammatory mediators were similar in the 2 CVS samples collected 8 months apart, suggesting that genital inflammation is stable in a subset of captive female RM. At both time points the cervicovaginal microbiota had low levels of Lactobacillus and was relatively diverse with an average of 13 genera in the samples from the first time point (median 13, range 7-21) and an average of 11.5 genera in the samples from the second time point (median 11, range 5-20). Many of the macaques had similar microbiota in the samples collected 8 months apart. However, we found no correlation between specific bacterial genera and the mRNA or protein levels of the inflammatory mediators in the genital tract of RM in this study. It seems likely that results of published vaginal SIV transmission experiments in RM have been influenced by pre-existing inflammation in the animals used for the experiments.

Long-retained vaginal foreign body causing chronic vaginitis in a bulldog.

A vaginal foreign body consisting of a piece of retained calvarium from a macerated fetus was identified and removed using vaginoscopy in a 4-year-old, spayed female bulldog. The dog had a 12-month history of chronic mucopurulent vaginitis. Vaginal foreign bodies, although uncommon, are a differential diagnosis for recurrent mucopurulent or hemorrhagic chronic vaginal discharge. A case of chronic vaginitis caused by a long-retained intravaginal foreign body in a dog is described and compared to four other canine cases reported in the literature.

Prevalence of potentially pathogenic bacteria as genital pathogens in dairy cattle.

Bacteria on the genital mucosa have been studied less in healthy, non-puerperal cows than in cows with puerperal endometritis. We have thus analysed bacteria in swabs from the vagina and cervix of post-puerperal cattle (n = 644). Out of the animals, 6.8% had aborted within the last 12 months, 2.6% and 11.6% showed signs of vaginitis and endometritis, respectively. In 17.2% of cervical swabs pathogenic gram-positive and in 11.5% pathogenic gram-negative bacteria were found. Arcanobacterium pyogenes was isolated from 41.3% of cows with endometritis and from 3.5% without endometritis (p < 0.05). From 12.5% of cows with abortion but from no cow without abortion, Staphylococcus aureus was recovered (p < 0.05). Out of 383 vaginal swabs, 88.3% were positive. In 3.4% of swabs pathogenic gram-positive and in 16.7% pathogenic gram-negative microorganisms were found. The percentage of positive vaginal swabs did not differ between pregnant and non-pregnant animals. In the genital tract, the percentage of swabs positive for normal mucosal bacteria decreased from caudally to cranially (p < 0.05). Pathogenic bacteria were found more often in cervical than in vaginal swabs (p < 0.05). In conclusion, bacteria on the vaginal and cervical mucosa in cattle involve a wide range of species. In animals without endometritis or vaginitis, colonization of the mucosa rather than infection has to be assumed.

Six novel gammaherpesviruses of Afrotheria provide insight into the early divergence of the Gammaherpesvirinae.

The Afrotheria represent an early branching of placental mammals. Only two herpesviruses from Afrotheria have been previously identified, and the genus Proboscivirus in the subfamily Betaherpesvirinae has been proposed for them. Six novel gammaherpesviruses were identified in four species in the superorder Afrotheria by detection and analysis of their DNA polymerase genes. Elephantid herpesvirus 3 (ElHV3) and Elephantid herpesvirus 4 (ElHV4) were identified from conjunctival swabs from Asian elephants (Elephas maximus). ElHV3 was also found in a vaginal swab from one elephant with vaginitis. Elephantid herpesvirus 5 (ElHV5) was identified from vaginal swabs of two Asian elephants with vaginal plaques. Elephantid herpesvirus 6 was discovered in a conjunctival swab from an African elephant (Loxodonta africana). Procavid herpesvirus 1 (PrHV1) was found in spleen and conjunctival swabs of rock hyrax (Procavia capensis). Trichechid herpesvirus 1 (TrHV1) was identified from skin and buffy coats of Florida manatees (Trichechus manatus latirostris). ElHV3 and ElHV4 form a distinct cluster, and ElHV5, ElHV6, TrHV1, and PrHV1 form a second cluster. These viruses may have codiverged with their host species. Phylogenetic analysis of these novel herpesviruses suggests that two separate groups of gammaherpesviruses may have codiverged with the Afrotheria.

Chronic vaginitis associated with vaginal foreign bodies in a cat.

A 2-year-old, spayed female, domestic shorthaired cat was presented for evaluation of a chronic, purulent vulvar discharge. Survey radiographs of the abdomen and pelvis revealed bone fragments in the pelvic canal. A vaginoscopy was performed, and five bony foreign bodies were removed from the vaginal lumen. Using anatomical landmarks, the bones were identified as remnants of a fetal kitten.

Quantitative detection of Chlamydia psittaci and C. pecorum by high-sensitivity real-time PCR reveals high prevalence of vaginal infection in cattle.

Bovine vaginal cytobrush specimens were analyzed for the presence of Chlamydia spp. by a high-sensitivity, high-specificity quantitative PCR. The 53% prevalence of low-level Chlamydia psittaci and C. pecorum genital infection detected in virgin heifers suggests predominantely extragenital transmission of Chlamydia in cattle and conforms to the high seroprevalence of anti-Chlamydia antibodies.

Isolation of Haemophilus somnus from dairy cattle in kwaZulu-Natal. An emerging cause of 'dirty cow syndrome' and infertility?

Haemophilus somnus was consistently isolated from vaginal discharges of dairy cows submitted from field cases of vaginitis, cervicitis and/or metritis in the KwaZulu-Natal Midlands during the period July 1995 - December 2000 and from the East Griqualand area in November/December 2000. The purulent vaginal discharges, red granular vaginitis and cervicitis, and pain on palpation described in these cases was very similar to that reported in outbreaks of H.somnus endometritis syndrome in Australia, Europe and North America. In all the herds involved in these outbreaks, natural breeding with bulls was employed. Although there was a good cure rate in clinically-affected animals treated with tetracyclines, culling rates for chronic infertility were unacceptably high. Employment of artificial insemination in these herds improved pregnancy rates in cows that had calved previously, but many cows that had formerly been infected failed to conceive.

Frustrating case presentations in canine theriogenology.

The practice of small animal theriogenology is rewarding, but frustrations exist concerning technologic advances as compared with other species. Reproductive clinicians striving to practice good quality medicine readily identify topics of common concern: causes that are not identified or therapeutics that are not available or applicable. Improved collaboration among theriogenologists specializing in small animal practice is evidenced by growing attendance at national and international scientific meetings, increased scientific publications, and internet communications.

Isolation, purification and characterization of the virus responsible for vaginitis, in cows, associated with infertility.

A virus isolated from vaginal exudate of cows with vaginitis showed molecular weight around 92 to 143 x 10(3) KD, density between 1.168 and 1.203 g/ml and physical, chemical and morphological properties characteristic of virus belonging to the herpes group. This virus was not reagent with the fluorescent antibodies of Infectious Bovine Rhinotracheitis (IBR) or Parainfluenza-3 (PI-3) viruses, frequently detected in cows with vaginitis.

[Infectious burdens of reproduction of female dogs]. / Infektiöse Belastungen der Reproduktion bei der Hündin.

The results of gynecological investigations in 142 bitches were evaluated and the complexity of infectious affections is discussed. High proportions of infectious cases were found in cases of limitation of fertility (67.5%), in vaginal discharge in the estrus (60.8%), in cases of mastitis/pseudopregnancy (61.5%) and in mortality of newborn puppies. St. aureus and E. coli were often isolated. There is a high etiological correlation in epidemiology of diseases of the reproductive tract in the single bitch and especially in kennel bitches.

Vaginal septa in dogs: 15 cases (1983-1992).

Medical records of 15 dogs with vaginal septa, examined between April 1983 and December 1992, were reviewed. Overall prevalence of vaginal septation at the hospital during the study period was 0.03%. Thirteen breeds were represented; mean age at the time of initial examination was 2.4 years. Owners' original complaints included inability to breed naturally, dysuria, urinary incontinence, infertility, recurrent vaginitis, ambiguous external genitalia, and dystocia. One dog did not have clinical signs associated with the vaginal septum. In 11 of the 15 dogs, the septum could be palpated during digital vaginal examination. The septum could be seen in 6 of the 7 dogs in which vaginoscopy was performed. Twelve of the 15 dogs underwent positive-contrast vaginography; in all 12, the septum could be easily seen. Four of the 15 dogs underwent removal of the septum, with or without episiotomy, and 4 others were ovariohysterectomized. One dog was bred by means of artificial insemination and became pregnant. The remaining 6 dogs were lost to follow-up.

Vaccination against bovine herpes mammillitis virus infections in guinea pigs.

Bovine herpes mammillitis virus or bovine herpesvirus type 2 (BHV-2) causes ulcerative lesions on the teats and udders of infected cows. Since no commercial vaccine is available for this disease, we investigated certain experimental BHV-2 vaccines against this virus in infected guinea pigs. Vaginally infected guinea pigs get severe, self-limiting vaginal infections characterized by erythema and swelling and the production of measurable vaginal virus titers. Two vaccine approaches were investigated: vaccination with wild-type (WT) virus by the subcutaneous route, and vaccination either subcutaneously or intravaginally with a thymidine kinase (TK) deficient (TK-) virus. The TK- strain was prepared by passage of BHV-2 in the presence of the potent TK-dependent antiviral agent 1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-methyluracil (FMAU). The antiviral activity of FMAU against the virus in plaque reduction assays changed from 0.05 to 2 microM at the same time that the TK activity of the mutant virus decrease to 7% of WT virus TK activity. Subcutaneous vaccination of guinea pigs with WT and TK- viruses did not induce vaginal infection. Primary vaginal infection (vaccination) with the TK- virus led to greatly reduced lesion severity compared to vaginal infection with the WT virus. However, the amount of vaginal virus titers recovered during these primary infections was similar for both TK- and WT viruses, indicating that both viruses had equal infecting potential. Thirty days after vaccination the animals were re-infected intravaginally with WT virus. The vaccinated animals showed dramatically reduced lesion severity and low recoverable virus titers compared to age-matched nonvaccinated animals.(ABSTRACT TRUNCATED AT 250 WORDS)

Aerobic bacteria occurring in the vagina of bitches with reproductive disorders.

A retrospective survey was performed of aerobic bacterial species found in the vagina of 203 bitches with genital disorders, e.g. infertility, vaginitis, pyometra and puppy death. Escherichia coli, beta-hemolytic streptococci, Staphylococcus intermedius and Pasteurella multocida were the species most often isolated. From bitches with pyometra E. coli in pure culture was the most frequent isolate. In contrast, the majority of infertile bitches gave rise to mixed cultures, and no specific bacterial species was consistently associated with infertility. Thus, bacterial sampling from infertile bitches was concluded to be of low diagnostic value. Bacterial species isolated from the bitches having vaginitis were present in pure culture in 26.9% of the samples while nonspecific mixed cultures were obtained from 34.6% of the samples from these bitches. E. coli was the most frequently isolated bacterial species from bitches with dead puppies. However, in such cases it is important to relate the vaginal bacterial findings to autopsy findings and the results of bacteriological cultures of the pups.

Thrombocytopenia associated with administration of trimethoprim/sulfadiazine in a dog.

A diagnosis of trimethoprim/sulfadiazine-induced, immune-mediated thrombocytopenia in a dog was made, using a novel in vitro assay for thrombolytic activity. The assay quantifies thrombolytic activity by measuring the amount of platelet fragments in normal canine platelets before and after incubation with plasma from the thrombocytopenic dog. This report confirms previous reports of the development of thrombocytopenia after administration of trimethoprim/sulfadiazine, and describes a new assay that, after further validation, may be useful in the diagnosis of immune-mediated thrombocytopenia when an adequate sample of platelets cannot be obtained for quantification of platelet-associated IgG.
