Amblyomma sculptum (formerly Amblyomma cajennense) ticks have been implicated in the transmission of pathogens that cause diseases in animals and humans. Their wide geographic distribution and high impact on animal health and zoonotic disease transmission highlight the importance of studying and implementing effective control measures to mitigate the risks associated with this tick species. The aim of this study was to quantify and characterize the morphology and the ultrastructure of different types of hemocytes in the hemolymph in engorged A.

Article Synopsis
  • Fipronil (FIP) is a topical ectoparasiticide that shows promise for oral administration due to risks of human exposure and environmental damage from existing formulations.
  • Evidence from studies demonstrated that FIP is effective against fleas and ticks in dogs, with optimal dosages providing near-complete efficacy at 48 hours post-treatment.
  • The pharmacokinetics of FIP indicated rapid absorption and metabolism but slower elimination, suggesting its potential as a safer and effective oral treatment option that aligns with the One Health concept for better health outcomes for animals, humans, and the environment.
