Molecular survey of tick-borne pathogens infecting backyard cattle and water buffaloes in Quezon Province, Philippines

Abstract

Tick-borne diseases (TBD) cause enormous losses for farmers. Backyard raising comprises majority of the livestock population in the Philippines, but TBD information in backyard livestock is scarce. In this study, 48 cattle and 114 water buffalo samples from Quezon province, Philippines were molecularly screened for tick-borne pathogens. Anaplasma marginale (16.67%) and hemoplasma (20.99%) were detected in the samples. A. marginale infection (P=0.0001) was significantly higher in cattle, while hemoplasma infection (P=0.011) was significantly higher in water buffaloes. A. marginale isolates from this study were highly similar to previous isolates from the Philippines while Mycoplasma wenyonii and Candidatus Mycoplasma haemobos were the identified hemoplasma species. Our findings reveal additional information on the TBD situation of Philippine backyard livestock.
