Pasteurella multocida is one of the most frequent causes of respiratory infection in sheep. A total of seven P. multocida were isolated from 195 sheep lung samples. All the isolates were tested to phenotypic antimicrobial resistance pattern with 14 antimicrobial agents. The organisms were found intermediate resistance 57.14% to Enrofloxacin, 42.85% to tetracycline, amoxicillin, 28.57% to colistin and clindamycin. The isolates were resistant to tetracycline (57.1%), clindamycin (42.86%) and chloramphenicol (28.57%) phenotypically. When the isolates observed for the presence of antibiotic resistance genes it was found100% presence of catA1, 71.42% presence of strB, 57.14% presence of strA, 42.8% presence of tet B and no amplification of sul1, sul2 and tet Agenes. These results indicated the increasing pattern of antibiotic resistance among P. multocida isolates.
