Goat pasteurellosis: serological analysis of circulating Pasteurella serotypes in Tanqua Aberegelle and Kola Tembien Districts, Northern Ethiopia.

OBJECTIVES

A cross-sectional study was employed with the aim to explore the serological status of goats; we evaluated the presence of serum antibodies of the circulating serotypes of the genus Pasteurella. A total of 124 serum samples were collected from randomly selected goats and subsequently serotyped using indirect haemagglutination test.

RESULTS

In the current study, the overall prevalence of pasteurellosis in goats was 31.4%. Additionally, a total of eight serotypes of Pasteurella were serotyped. It is evident that 25% out of 124 sampled animals were found infected by four or more circulating serotypes and 6.4% animals were also found positive for all serotypes. Accordingly, the prevalence of Pasteurella multocida serotype A were 16.9%, Mannheimia haemolytica serotype A1 26.6%, M. haemolytica serotype A2 18.5%, M. haemolytica serotype A7 16.1%, Bibersteinia trehalosi serotype T3 20.9%, B. trehalosi serotype T4 21.7%, B. trehalosi serotype T10 27.4%, and B. trehalosi serotype T15 was 25.8%. Therefore, although there has been vaccination campaign with monovalent vaccine P. multocida type A, the diseases still exerts negative impacts through death of goats to smallholder farmers. Therefore, to control the disease the government should provide multivalent vaccine of the above serotypes.
