Article Synopsis
- - The study focused on the insecticidal and repellent properties of essential oils from four plants, targeting the flea Ctenocephalides felis, which affects pets and humans globally.
- - Using Gas Chromatography, researchers analyzed the chemical composition of the oils and tested their efficacy against different flea life stages, calculating lethal concentrations for each.
- - Results indicated that certain oils, particularly from Copaifera reticulata, showed significant insecticidal activity and residual effectiveness, making them potential alternatives to chemical pesticides.
Background: Brazilian spotted fever (BSF), the most lethal tick-borne disease in the Western Hemisphere, is caused by the bacterium Rickettsia rickettsii and transmitted by the bite of Amblyomma sculptum. Capybaras are considered primary hosts of this tick and amplifier hosts of R. rickettsii, generating new infected lineages of A.

- 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.
Background: Dermatobia hominis (D. hominis) is a botfly that causes furuncular myiasis in several species of domestic and wild animals. However, reports of feline infestation by larvae of this dipteran are rare.
