In India, limited studies are available on the epidemiological aspects of methicillin-resistant (MRSA) infections in both animal and human settings. Herein, we investigated the prevalence, antimicrobial resistance profile and molecular characteristics of MRSA isolates recovered from cattle using the One Health approach. Out of 66 A-positive staphylococci, species-specific multiplex PCR detected 24 % (=16) of isolates as MRSA.

β-lactamase mediated resistance in Escherichia coli is a significant problem that requires immediate attention. Herein, we aim to characterize and understand the dynamics of the genetic determinants of β-lactam resistance (i.e.

Background And Aim: Methicillin-resistant staphylococci are among the emerging pathogens which have become a threat to both human and animal health. The present investigation intended to examine the occurrence and the molecular characteristics of methicillin-resistant (MRSA) and methicillin-resistant coagulase-negative staphylococci (MRCoNS) recovered from cattle, its handlers, and their environment.

Materials And Methods: A total of 666 specimens were subjected to culture method and genus-specific polymerase chain reaction (PCR) for the identification of .

Objectives: The aim of this study was to identify and characterise probable extended-spectrum β-lactamase (ESBL)-, AmpC lactamase- and/or metallo-β-lactamase (MBL)-producing Escherichia coli variants circulating in the livestock and poultry environment to establish their epidemiological significance, genetic diversity, antimicrobial resistance (AMR) trends and virulence.

Methods: The culture method and E. coli-specific multiplex PCR identified 78 E.
