Drug sensitivity profile of various capsular types of Pasteurella multocida in Himachal Pradesh

Abstract

An experiment was carried out to study the antibacterial sensitivity of various capsular types of Pasteurella multocida with the purpose of controlling and treating pasteurellosis in different species of animals in Himachal Pradesh. A total of 144 strains of Pasteurella multocida isolated from different species of 144 animals {cattle (44), buffaloes (49), sheep (6) goats (7), rabbits (29), poultry(8) and canine (1)}, from different parts of the State were subjected to drug sensitivity test using 30 different antimicrobials. A total of 27 isolates were of Capsular serotype A, while, 117 isolates were identified as Capsular serotype B. Capsular serotype A of Pasteurella multocida was found to be highly sensitive to cefriaxone, cefotaxime, chloramphenicol, enrofloxacin, ciprofloxacin, ofloxacin, nitrofurantoin and norfloxacin, while capsular serotype B of Pasteurella multocida were mostly sensitive to the antimicrobial agents like ceftriaxone, cefotaxime, cephalexin, enrofloxacin, chloramphenicol, ciprofloxacin, ofloxacin, nitrofurantoin and norfloxacin. Both Capsular type A and type B were found to be highly resistant to ceftiofur, cefuroxime, ampicillin, steptomycin, chlortetracycline and clotrimazole.
