Abstract: SAMANIEGO, CHERRYMAY O. MOLECULAR DETECTION OF TICK- BORNE FLAVIVIRUSES IN BLOOD OF CATTLE IN CAVITE, PHILIPPINES. Thesis, Doctor of Veterinary Medicine, Cavite State University, Indang, Cavite. 2019. Adviser: Melbourne R. Talactac, DVM, MS, PhD. This study was conducted to detect the presence of tick- borne Flaviviruses (TBFV) in cattle from selected farms in Cavite. A total of one hundred blood samples were collected from the dorsal ear vein of cattle from different municipalities in Cavite. RNA samples extracted from the blood were used for complementary DNA (cDNA) synthesis. The cDNAs were initially used for the detection of mammalian Actin gene and later on, for the NS5 gene coding region conserved in TBFV using conventional Polymerase Chain Reaction (PCR). All blood samples were positive for mammalian Actin gene, however, TBFV were not detected. The result of this study suggested that TBFV may not be present in the areas where the samples were collected. Occurence of previous infection is possible but as a limitation of the study, PCR only detects present viremia in an animal through amplification of the target gene. The author recommends that further studies be conducted with larger sample size. Moreover, the time of collection should cover the warmer season because the presence of ticks in the area is important in spreading the virus. Lastly, animals should have tick infestation to be included in the study and serological tests should be utilized for improved detection.
