Abstract

A total of 352 animals (cattle-182; buffalo-170) from Cabacan, Matalam and Ma-a abattoir slaughter house in Davao City [Philippines] were used in this study. Approximately 6 mL was collected for serological examination using Card Agglutination Test for Trypanosoma evansi (CATT/T. evansi). A wet mount examination was performed to detect the presence of T. evansi in the blood. Fecal samples were collected to determine the presence of liver fluke, roundworms, giardia, cryposporidia and coccidian. Nasopharyngeal swabs collected from the animals slaughtered at the Ma-a abbatoir was used in an attempt to isolate Pasteurella multocida. Overall result showed that the prevalence of surra in animals raised in Kabacan was higher (20%) compared to Matalam (13%). Risk assessment analysis revealed that a surra positive buffalo was six times more likely to be infected with P. multocida than surra negative buffalo. The surra positive buffaloes were two times more likely to be infected with roundworms and liverfluke than surra negative buffaloes. Interestingly, surra positive buffaloes were more susceptible to pasteurellosis and parasitic infection, than surra positive cattle. The calculated risk for age on the seropositivity indicated that cattle ages up to two-years old are three times more likely to get infected with T. evansi. On the contrary, the age of buffaloes did not influence seropositivity. All animals examined were positive with coccidian however; both giardia and cryptosporidia were not detected.
