ABSTRACT
Isolation of multiple drug resistant (MDR) bacteria with potential of extended spectrum β–lactamases (ESBL) and carbapenemase production from vaginal swabs of apparently healthy swamp buffaloes is reported for the first time. A total of 57 bacterial isolates belonging to 18 species were isolated from vaginal swabs of apparently healthy swamp buffaloes. Escherichia coli was the most common bacteria isolated from 68% samples followed by Enterobacter agglomerans (32%), Klebsiella pneumoniae (16%), Erwinia amylovora (16%), Aeromonas media (12%), Alkaligenes denitrificans (12%) and Aeromonas hydrophila (8%). A total of 35.1 % isolates had MDR and 14 isolates were phenotypically confirmed as producer of crabapenemase or ESBL. Resistance to ampicillin was the most common (68.4%) followed by resistance to ceftazidime (33.3%), nitrofurantoin (31.6%) and cotrimoxazole (21.1%). Resistance to imipenem, aztreonam and ceftazidime + clavulanic acid was detected in 5, 5 and 9 isolates, respectively. The study conclude that vagina of swamp buffaloes may carry several microbes having multiple drug resistance without any apparent illness.

Key Words: Escherichia coli, Enterobacter agglomerans, Klebsiella pneumoniae, Erwinia amylovora, Aeromonas media, Alkaligenes denitrificans, Aeromonas hydrophila.
