Incidence and Antibiotic Susceptibility Profile of Pasteurella Maltocida Isolates Isolated from Goats in Savar Area of Bangladesh

Abstract

In Bangladesh, goat farming is substantially hampered due to outbreaks of respiratory infectious diseases like pneumonia causing morbidity, mortality and economic losses in Black Bengal goats. Among the infectious agents, Pasteurella maltocida is more frequently associated with the outbreak of acute pneumonia and death of goats. Hence, the occurrence of P. multocida in the goat population should be regularly investigated to effectively control the disease. Furthermore, antibiotic resistance/sensitivity profiling of P. maltocida also needs to be regularly updated for designing or updating of efficient treatment strategy. In this investigation, 150 nasal swab samples from goats were collected from Savar region of Bangladesh and on the basis of colony, staining and biochemical characteristics P. multocida were isolated in 25 samples. Disc diffusion assay was used to determine the antimicrobial susceptibility of 20 isolates against 9 different antimicrobial agents. This study revealed that the rate of P. multocida isolated from goats in Savar area was about 16.67%. The incidence of P. multocida was higher in goats affected with acute pneumonia than apparently healthy goats. P. multocida was fully resistant to penicillin and amoxicillin whereas showed high sensitivity towards ciprofloxacin followed by streptomycin and neomycin. This study suggests that ciprofloxacin, streptomycin and neomycin are potent anti-Pasteurella multocida drugs.
