Abstract:
:The water buffalo industry is a vital part of the Philippine livestock economy and is an essential contributor to the developing local dairy industry. Although relatively less susceptible to diseases, water buffaloes can still be infected and can act as reservoirs of tick-borne pathogens (TBPs). However, limited information is available regarding the prevalence of tick-borne infections in water buffaloes in the Philippines. This study was conducted to identify TBPs harbored by water buffaloes and to characterize these pathogens molecularly. One hundred water buffalo blood samples collected from three areas in Bohol, Visayas region, Philippines were screened for various TBPs using pathogen-specific PCR assays. TBPs were detected in 46% of the samples (39% singly infected, 7% coinfected). The pathogens detected were Anaplasma marginale (29%), Babesia bovis (21%), and B. bigemina (3%). None of the blood samples were positive for Theileria annulata, T. orientalis, and B. ovata. A. marginale infection rates were significantly higher (37.5%) among water buffaloes aged ≤6 years (P = 0.046) than those >6 years old (18.2%) and was detected only in Bulgarian Murrah (36.1%) and US Murrah (25.9%) breeds. Phylogenetic analyses revealed that groEL sequences of A. marginale were 100% identical with isolates from the Philippines (Batangas and Cebu) and China. Two B. bigemina RAP-1a gene sequences were identical to each other and were homologous with previous isolates from Thailand, Indonesia, Uruguay, and the Philippines. Moreover, four B. bovis SBP-2 partial sequences obtained in this study had 92.4-99.7% identities. This study is the first molecular detection and characterization of A. marginale, B. bigemina and B. bovis in water buffaloes in the Visayas region, and the first molecular confirmation of B. bovis infection in water buffaloes in the country. The findings presented in this study may serve as baseline data for crafting effective tick-borne disease surveillance and prevention programs in Bohol and in the Philippines.
