Isolation and identification of some genera and species of bacteria and fungi from conjunctiva in cattle in Al-Diwaniya city

[摘要] This study was designed to identify some genera and species of bacteria and fungi that infect conjunctiva in cattle, as the studies on this subject are few somewhat, especially those that include isolating fungi that infect the conjunctiva as rare cases and that may be caused by low body immunity after topical corticosteroid and antibacterial therapy to an inflamed eye, This study included examination of (100) eye swabs, from cows from different ages and regions in diwaniya city. This study extended from 1/5/2012 – 27/11/ 2012. The samples were collected from clinically healthy and infected eyes of animals. (7) bacterial species were isolated they included Staphylococcus spp. 26.4% , E. coli 24.8%, Staphylococcus aureus 19% , Moraxella bovis 9.9% , Streptococcus spp. 8.3%, , , Pseudomonas spp. 8.3%, Proteus spp. 3.3%. The isolated bacteria were 121, Gram positive bacteria were 63 (52.1%) while Gram negative bacteria 58 (47.9%). Many types of bacteria isolated from healthy swabs 75 (62%) and 46 (38.1%) from infected swabs. The study also included isolation and identification of some species of fungi associated with the mycotic conjunctivitis in cattle, the observed study Aspergillus niger was the most frequent species isolated and was accounted to 37.5% of all isolates, while other fungi included Aspergillus fumigates 25% , Alternaria spp. 25% and Penicillium spp. 12.5%.
