Abstract

 
BACKGROUND: Microorganisms are responsible for development of many diseases, which directly or indirectly affect reproductive performance in mares, like various animal species. Fungi are present at mucous membranes of reproductive tract as mycoflora in warm blooded animals. ObjectiveS: The aim of this study was isolation and identification of molds of external reproductive tract in mares. Methods: Samples were collected from genital tract of 151 mares in different ages from horse breeding farms and clubs suburb of Tehran from April to December, 2014. Age, pregnancy, insemination and mating were recorded. Samples were taken by sterile cotton swabs from 3 different sites, (1) vestibule, (2) clitoral fossa and (3) vagina and transferred under cold condition to the laboratory of Mycology Research Center, Faculty of Veterinary Medicine, University of Tehran,Iran. Samples were inoculated in Sabouraud glucose agar supplemented with antibiotic (chloramphenicol; 0.005) and kept at 30°C for 10-15 days before being considered negative. Fungal identification relied on morphologic and physiologic features. SPSS Version 20 was used for statistical analysis of the data. Results: Totally, 666 filamentous fungi colonies were isolated. Maximum colony (CFUs) were 20 and 37 colonies for each site and horse, respectively. In total, 81.5 percent of mares and 48.3 percent of different sites were positive. The most predominant isolates were Aspergillus spp 362(54.35%), Scopulariopsis 93(13.96%), Cladosporium 35(5.25%), Penicillium 31(4.65%), Alternaria 26(3.90%), Fusarium 20(3.03%). Aspergillus took high occurrence with 362 and A. fumigatus with 156 colonies followed by Scopulariopsis 93, Cladosporium 35 and Pencillium 31. A. fumigatus had significant difference among other fungi pConclusionS: Isolated filamentous fungi could be resident flora of external reproductive tract of mares. These saprophytic pathogen fungi in predisposing conditions could be causative agents of endometritis and infertility in mares.
