Importance: African swine fever (ASF) is a contagious transboundary swine disease that poses a significant threat to the swine industry. As an archipelago, the Philippines has a geographic advantage in reducing ASF transmission risk. However, control efforts remain challenging due to the disease's complex epidemiology, lack of effective treatment, and vaccine availability.

African swine fever (ASF) is a contagious hemorrhagic disease affecting both domestic and wild pigs with high mortality rate and severe socio-economic losses. Due to the virus' potential ability to remain infectious in suitable conditions and environments, it is imperative to identify risk factors that may contribute to its transmission. The Philippines' current ASF surveillance relies on pig blood samples.

and are tick-borne protozoan parasites that can cause significant economic losses in the cattle industry. This study aimed to contribute to the limited epidemiological data on as well as and in large ruminants in the Philippines. Blood samples of 412 cattle and 108 water buffalo collected from four provinces in Southern Luzon, Philippines, were initially tested for the gene of piroplasms through nested PCR.

Article Synopsis
  • Tick infestations significantly impact the global cattle industry, and amitraz is commonly used to combat the Rhipicephalus (Boophilus) microplus tick.
  • A study in the Philippines assessed the resistance of cattle ticks from northern and southern Luzon to amitraz, using both larval packet tests and genetic analysis.
  • While no resistance was detected in the tested tick populations, some genetic similarities to resistant strains were found, suggesting the importance of careful amitraz use to prevent future resistance development.
