Diversity of Ticks in the Caribbean Region and Detection of Their Pathogens Using BioMark Technology. [PDF]

Transbound Emerg Dis
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.
