ABSTRACT
Cattle routinely exposed to mycoses because of the poor hygienic practices in animal ranches that lead to the infection of the udder and this eventually transcends to contamination of milk. Cutaneous mycoses are mostly fungal infection of the stratum corneum. The objective of the current study was to examine the cattle and cattle beddings for fungal organisms in correlation with that found in milk. Scrapings of fungal lesions from 302 cattle were examined alongside with samples of milk and sawdust beddings. Culture, identification and characterization of isolates were carried out using standard methods. Antifungal biogram was performed. Result showed that all the cattle and the bedding tested positive for fungi, while 41(82%) of the milk samples had fungal contamination. Rate of isolation from cattle, bedding and the milk was not significantly (P= 0.365) different. The distributions of various species within the bedding was significantly different (P= 0.001). Trichophyton mentagrophytes had the highest rate in the beddings (22%) followed by T. verrucosum (16%), while T. verrucosum had highest occurrence rate (24.2%) in cattle samples followed by the T. mentagrophytes (21.2%). Candida albicans was the most prevalent specie in milk (46.3%), followed by F. solani (31.7%). The correlation coefficient(r) in the bedding and the cattle was 0.695 (P>0.05), that of the cattle and the milk was 0.000 (P<0.05). The r value of the bedding and the milk was 0.322(P>0.05). Fluconazole inhibited the growth of all the dermatophytes. Most of the isolates were resistant to Miconazole except T. mentagrophyte which showed 83.0% sensitivity. Contamination of the dairy likely resulted from contamination of the cattle bedding and infection of the udder.
