In-vitro Sensitivity of Commonly Used Antibiotics in Cattle of Kashmir Valley

Background: Antibiotic sensitivity testing is a very important tool in the hands of a clinician to evaluate the sensitivity of the pathogen involved in a disease. It is an important aspect of rational use of antibiotics thus minimizing the risk of occurrence of drug residues in animal foods like milk and meat. Methods: The samples from mastititic milk and respiratory and urinary samples from the cattle having the respective infections collected from Veterinary Clinical Complex, FVSc Shuhama from July 2021 to January, 2022 were subjected to in vitro antibacterial sensitivity testing to six commonly used antibiotics viz. gentamicin, enrofloxacin, tetracycline, streptomycin, ceftriaxone and pencillin. Result: A total of 30 mastitic milk samples, 8 from respiratory infections and 6 from urinary infections were studied. The drug gentamicin proved to be most efficacious against these infections while the drug pencillin proved to be most resistant. Gentamicin proved to be 73.34% efficacious while Pencillin proved to be only 6.67% efficacious in mastitic milk sample from cattle.
