Correlation Analysis of Antimicrobial Resistance Coexistence among Bacterial Pathogens Associated with Bovine Mastitis

In the era of AMR,it is essential to understand and correlate AMR among pathogens of clinical importance. Analysis of AMR pattern among bovine mastitis pathogens revealed that isolates ofStaphylococcus spp.,Streptococcus spp.and Klebsiella spp. were either multior extensivelydrug-resistant, and none of the E. coli were resistant to multiple antimicrobials. Further, pMAR index revealed a7.89 – 15.13 % possibility that an isolate mightnot be amenable to first-line antimicrobials. Correlation of coexisting resistanceindicated a weak correlation among β-lactams and a moderate to weak correlation between β-lactams and gentamicin. This analysis will shed more light onto AMR coexistence and might help clinicians in choosing correct antimicrobials.
