Antibiotics are routinely used in animals and birds to prevent and cure bacterial infections. Various multidrug resistance bacteria have been detected in caged zoo birds, however there is a little known about their resistance pattern. In current study we isolated and identified cloacal bacteria from 50 zoo birds and compared their antimicrobial susceptibility. A total of 28 cloacal samples (56%) were found positive for different bacteria by selective culture. The bacteria isolated from different types of caged birds were Escherichia coli (26%), Staphylococcus spp. (8%), Streptococcus spp. (4%) and some unidentified Gram-positive and Gram-negative bacteria (14%). Of these isolates, E. coli was the most frequent isolate. The results of antibiotic sensitivity tests revealed that cefotaxime and sulphadiazine were highly (>60%) resistant to isolated cloacal microflora of zoo birds. However, the antibiotics such as ceftriaxone and amikacin showed moderate to high sensitivity against almost all the bacterial isolates. Of these, co-trimoxazole was found to be consistently highly effective (100%) on all the E. coli isolates. Overall, the results showed that zoo birds can be carrier of multidrug resistant organisms including Escherichia coli.
