Abstract

The present study was undertaken with the objective of isolation and identification of bacterial species causing respiratory diseases in sheep and goat in Warangal region of Telangana, India. A total of 191 nasal and lung tissue samples were collected from sheep and goats. Bacterial identification was conducted through classical cultivation, biochemical identification and standard molecular method (Polymerase Chain Reaction). Upon bacterial screening, 7 different bacterial species were isolated.Of all the etiological agents identified, Staphylococcus spp. (42.93%) was found to be predominant followed by E. coli (17.28%),P. multocida (15.7%), Klebsiella spp. (11%), Proteus spp. (4.71%), M. haemolytica (3.67%), Pseudomonas spp. (3.14%) and Streptococcus spp. (1.57%)., Thisstudy supported the concept of the multi-bacterial etiology of the respiratory infections among sheep and goat flocks. The present study warrants extensive studies involving large number of samples to develop suitable vaccine, treatment and control strategies to reduce the morbidity and mortality arising due to mixed respiratory infections in sheep and goat.
