Fluralaner and Enzootic Stability of Tick Fever in Tropical Beef Calves Under Strategic Tick Control
Introduction Tick-borne diseases remain a major challenge for beef cattle in tropical regions. The enzootic stability of Theileria- and Babesia-caused infections depends on exposure levels to pathogens like Anaplasma marginale, Babesia bovis, and Babesia bigemina, balanced against tick burdens. This study investigates whether strategic use of fluralaner (Exzolt® 5%) affects enzootic stability in crossbred beef…

Fluralaner for Strategic Tick Control: Does it Disrupt Enzootic Stability of Tick Fever in Tropical Crossbred Calves?
Introduction Tick-borne fever (TF) pathogens, including Anaplasma marginale and Babesia species (B. bovis and B. bigemina), pose a persistent challenge in tropical beef systems. Enzootic stability—where most animals harbor antibodies without clinical disease—helps farmers maintain herd health even as pathogen exposure continues. A recent field comparison on a commercial Brazilian cattle farm explored whether strategic…

Does Fluralaner Affect Enzootic Stability of Tick Fever in Tropical Beef Calves Under Strategic Tick Control?
Introduction Tick fever (TF), caused by pathogens such as Anaplasma marginale, Babesia bigemina, and Babesia bovis, remains a major health and economic concern for cattle in tropical regions. Enzootic stability—a situation where most animals have subclinical exposure and herd-level immunity—guards against severe outbreaks. A common question for producers is whether introducing a highly effective acaricide…
