Clostridial infections in goats have been associated frequently with enteric diseases or gas gangrene but very rarely with the reproductive system. We describe here 12 cases of fatal postpartum gangrenous metritis in does associated with infection by several clostridial species. Clinically, these cases were characterized by rapid onset of hyperthermia followed by death after kidding. On postmortem examination, the uteri appeared to be necrotic and were hemorrhagic and edematous. Microscopically, the uteri had diffuse coagulative necrosis, edema, hemorrhage, and fibrinous thrombi with intralesional gram-positive rods. Clostridium perfringens was isolated from 7 of 9 uterine samples cultured, and C. perfringens, C. septicum, C. novyi, or C. chauvoei were demonstrated by immunohistochemistry (IHC) in the 5 cases examined. IHC for Paeniclostridium sordellii was negative in all 5 cases. PCR performed on 3 of the C. perfringens isolates was positive for alpha toxin and perfringolysin, identifying these isolates as type A. Clostridial infection should be considered in cases of postpartum gangrenous metritis of does. [ABSTRACT FROM AUTHOR]

Introduction:Clostridium perfringens and other gas gangrene-forming clostridia are commensals of the human gut and vaginal microbiota, but can cause serious or even fatal infections. As there are relatively few published studies on antibiotic susceptibility of these bacteria, we decided to perform a 10-year retrospective study in a South-Eastern Hungarian clinical centre. Methods: A total of 372 gas gangrene-forming Clostridium spp. were isolated from clinically relevant samples and identified with rapid ID 32A (bioMérieux, France) and MALDI-TOF MS (Bruker Daltinics, Germany) methods. Antibiotic susceptibility was determined with E-tests. Results: We identified 313 C. perfringens, 20 C. septicum, 10 C. sordellii, 10 C. sporogenes, 9 C. tertium, 6 C. bifermentans, 4 C. histolyticum isolates. In C. perfringens isolates, the rate of penicillin resistance was 2.6% and the rate of clindamycin resistance 3.8%. Penicillin resistance was found in 6.8% and clindamycin resistance in 8.5% of the non-perfringens Clostridium spp. isolates. Conclusion: The antibiotic susceptibility of C. perfringens isolates was in good agreement with previous publications. The rates of resistance to penicillin and clindamycin were very low. The resistance rates of non-perfringens Clostridium spp. isolates were higher than those of C. perfringens strains, but lower than those published in the literature. [ABSTRACT FROM AUTHOR]
