Numerous studies on endometritis of postpartum dairy cows describe the bacterial aetiology of the condition. However, studies on fungal agents causing inflammatory conditions of the reproductive tract are limited. The objective of the present study was to identify the mycotic isolates from the reproductive tract of postpartum dairy cows and analyse their susceptibility to antifungal agents. In this study, 70 endometrial cytobrush samples were collected from dairy cows 40 - 120 days postpartum (dpp) and cultured in Sabouraud dextrose agar (SDA). The isolated fungal cultures were identified by Lactophenol Cotton Blue staining and were subjected to antifungal susceptibility testing. The frequency of isolation of fungi from endometrial samples was 15.71 per cent (11/70). Aspergillus niger was isolated from four (33.33%) samples, followed by Penicillium spp. (25%), Aspergillus fumigatus (16.67%), Mucor spp. (16.67%) and Absidia spp. (8.33%). Antifungal susceptibility testing revealed that 50 per cent of the isolates were susceptible to fluconazole, whereas only 25 per cent of the isolates were completely resistant to amphotericin-B. The prevalence of fungal infection in reproductive tract was higher in cows with an age of ≥ 5 years and a parity of ≥ 2, though this was not significant. A significantly higher number of cattle with history of intrauterine antibiotic therapy were positive for fungal culture. However, the association between prevalence of fungi and reproductive complications was statistically non-significant.
