A total of 65 Pasteurella multocida were isolated and identified from various animals samples received by Veterinary Research Institute (VRI) during the period of 2014 to 2016. These animals comprises of cattle goat pig chicken duck and rabbit. The serogroup of Pasteurella multocida were carried out using designation system of Carters capsular typing and molecular serogrouping method. Based on cases submitted to VRI the prevalence of pasteurellosis in Malaysia ranging from 1.0 to 3.2 (2014 to 2016). It is low compared to previous reports and the pattern of predominant serogroups and animal hosts were found to be changing every year. In 2014 80 (12/15) of the isolates were Pasteurella multocida Carters type D where all were isolated from goats. In 2015 the predominant serogroup changed to Pasteurella multocida Carters type A with a prevalence rate of 40.6 (13/32) which were mostly isolated from duck and cattle. While for Pasteurella multocida Carters type D the prevalence in 2015 reduced to 21.9 (7/32) compared to the previous year and it was isolated from various animal species. Interestingly in 2015 there was one isolate of Pasteurella multocida Carters type B isolated from goat with no reported history of outbreak. In 2016 the prevalence of Pasteurella multocida Carters type A increased to 72.2 (13/18) with a high percentage (92.3) infection in young calves showing clinical signs with high mortality and morbidity in infected farms. Furthermore during these 3 years of study 3 isolates of Pasteurella multocida serogroup F were also identified each from pig goat and chicken respectively. In conclusion this study revealed that pasteurellosis had become sporadic in Malaysia and the distribution of serogroups were diverse in all species of animal with no definitive host.

Abstract

A total of 65 Pasteurella multocida were isolated and identified from various animals samples received by Veterinary Research Institute (VRI) during the period of 2014 to 2016. These animals comprises of cattle goat pig chicken duck and rabbit. The serogroup of Pasteurella multocida were carried out using designation system of Carters capsular typing and molecular serogrouping method. Based on cases submitted to VRI the prevalence of pasteurellosis in Malaysia ranging from 1.0 to 3.2 (2014 to 2016). It is low compared to previous reports and the pattern of predominant serogroups and animal hosts were found to be changing every year. In 2014 80 (12/15) of the isolates were Pasteurella multocida Carters type D where all were isolated from goats. In 2015 the predominant serogroup changed to Pasteurella multocida Carters type A with a prevalence rate of 40.6 (13/32) which were mostly isolated from duck and cattle. While for Pasteurella multocida Carters type D the prevalence in 2015 reduced to 21.9 (7/32) compared to the previous year and it was isolated from various animal species. Interestingly in 2015 there was one isolate of Pasteurella multocida Carters type B isolated from goat with no reported history of outbreak. In 2016 the prevalence of Pasteurella multocida Carters type A increased to 72.2 (13/18) with a high percentage (92.3) infection in young calves showing clinical signs with high mortality and morbidity in infected farms. Furthermore during these 3 years of study 3 isolates of Pasteurella multocida serogroup F were also identified each from pig goat and chicken respectively. In conclusion this study revealed that pasteurellosis had become sporadic in Malaysia and the distribution of serogroups were diverse in all species of animal with no definitive host.
