An Immunosuppressant Peptide from the Hard Tick Amblyomma variegatum [PDF]

Toxins, 2016
Ixodid ticks are well known for spreading transmitted tick-borne pathogens while being attached to their hosts for almost 1–2 weeks to obtain blood meals. Thus, they must secrete many immunosuppressant factors to combat the hosts’ immune system.

Detection of Multiple Microorganisms in Ruminant Ticks in Senegal Using High-Throughput Microfluidic Real-Time PCR. [PDF]

Transbound Emerg Dis
Ticks are major vectors of numerous pathogens affecting both livestock and humans. In Senegal, data on the diversity of tick‐borne pathogens (TBPs) in ruminant‐associated ticks remain limited. In total, 1703 ticks were collected from goats, sheep, and cattle across three ecological zones of Senegal (Sudanian, Sahelian, and Sudano‐Sahelian).

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.
