Isolation, characterisation and prevalence pattern of bacterial flora on pneumonic cases of goats slaughtered at Thanjavur abattoir, Cauvery Delta Zone, Tamilnadu

Abstract

Respiratory infections of goats irrespective of the breed cause indirect economic loss to the farmer and the industry. The present study was aimed to isolate and identify the bacterial population associated in goats slaughtered at Thanjavur District Abattoir of Cauvery Delta Zone (CDZ), Tamil Nadu, India. The pneumonic cases were segregated from the list of slaughtered goats and trachea and lungs were collected and proceeded as per standard protocols from 230 goats during August 2019 to February 2020(6 month period)brought to the Thanjavur District abattoir. A total of 178 were affected with various types of pneumonia based on goats morphology of lungs with two types of pneumonia. Bacterial pneumonia contributed 88.7% and verminous pneumonia existed in 11.3% of slaughtered goats. Out of 178 pneumonic lungs collected from August 2019 to January 2020 (6 months) upon bacterial investigation revealed Staphylococcus spp, Pasteurella multocida, Streptococcus pyogenes and E.coli predominantly with a lesser contamination of Candida spp. The population of Gram positive bacteria was more than the Gram positive ones from the above study.
