Diversity of Ticks in the Caribbean Region and Detection of Their Pathogens Using BioMark Technology

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Introduction Ticks and the pathogens they transmit are widespread in Caribbean animal populations. There is; however, limited information on the diversity of ticks and tick‐borne pathogens (TTBPs) in the region. This study aims to identify TTBPs across multiple Caribbean countries using a high‐throughput real‐time microfluidic PCR system.

Effects of urea on the cattle tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)

Veterinary Parasitology, 2010
This study aimed at evaluating the effects of urea on Rhipicephalus (Boophilus) microplus. The experiment was divided into two stages. In Stage I, Brachiaria brizantha was placed into 30 pots, each with an area of 18 cm(2).These were divided into three groups of ten pots each: G1 non-treated control group, G2 treated with 15 g of urea per pot and G3 ...
