Abstract
Antimicrobial resistance is a global public health threat having grave sequel, and is becoming worse day by day in communities and healthcare settings. Frequent use of antimicrobial agents in food animal along with various risk factors enhancing the global burden of drug resistant bugs. One hundred and fifty swab samples were screened to determine the level of bacterial burden in the study population. All samples were subjected to various cultural and biochemical tests to isolates the bacterial pathogens from pneumoenteritic goats. Staphylococcus sp, Escherichia coli and Salmonella were identified and subjected to antibiotic sensitivity tests. Out of 150 nasal swab samples 28% were found to be positive for Staphylococcus sp in all cultural and biochemical tests. Eighty eight E. coli isolates were screened out from both fecal and nasal swab samples that reflected the prevalence was 29.3 % in affected goats. 16.6% prevalence of Salmonella was recorded and found to be positive in all cultural and biochemical tests as well as through serotyping. All positive bacterial isolates were subjected to antibiotic susceptibility testing. The study revealed most bacterial isolates were resistant to commonly used antibiotics like penicillin, ampicillin, amoxicillin, oxacillin, vancomycin. Development and carriage of antimicrobial resistance genes in food animals pose significant public health threat. Because resistant gene from pathogenic bacterium can easily transmitted to commensal bacterium resulting development of drug resistance in human leads to failure of treatment by available drugs.
