The results also revealed 26 out of 50 (52%) bovine lung samples were positive for fungal isolatation, February expressed high fungal isolation (58.82%), while April showed low percentage of fungal isolation (40%), the main fungal isolates from bovine lungs included Candida spp in high percentage (38.46%) especially C.albicans (23.07%) followed by C.tropicalis and C.stellatoidea (7.69%) for each one, Aspergillus fumigatus and Rhizopus spp 3 out 26 (11.53%) for each one, Mucor spp and Penicillium spp 2 out of 26 (7.69%) for each one, as well as the lower percentage of Aspergillus niger, Botrytis aclada, Cladosporium herbarum, Fusarium spp, Cryptococcus neoformans and Alterneria alternate 1 out of 26 (3.84%).
