Abstract

A study was conducted with the objectives to isolate, identify and characterize bacterial pathogens from pneumonia suspected samples of sheep and goats collected from veterinary clinic and slaughterhouses in and around Hyderabad, Telangana. A total of 112 bacterial isolates were recovered from 101 lung and nasal discharge samples of sheep and goats. The maximum prevalent bacteria were Staphylococcus aureus (49.10%), followed by Klebsiella pneumoniae (37.51%) and Pseudomonas aeruginosa (13.39%). Further, virulence-associated spa gene was detected in 72.7% of Staphylococcus isolates while uge gene of Klebsiella was detected in 61.9% of the isolates. The spa gene, uge gene, 16S RNA sequence of S. aureus, K. pneumonia and P. aeruginosa isolates showed high identities with United Kingdom isolates of S. aureus, United Kingdom isolates of K. pneumonia and Sudan isolates of P. aeruginosa, respectively. It was concluded that pneumonia is a multifactoral disease and the presence of various virulent associated genes among the isolates indicates their potential to resist the host immune to cause the disease.
