Diseases transmitted by vectors are called vector-borne diseases. Many vector-borne diseases are zoonotic diseases, i.e. diseases that can be transmitted directly or indirectly between animals and humans. These include for example Lyme disease, tick-borne encephalitis, west nile virus, Leishmaniosis and Crimean-Congo haemorrhagic fever.

A new report from the Centers for Disease Control and Prevention has. of vectors with proven or possible capacity to transmit a wide range of.

 · Rickettsia is a genus of nonmotile, gram-negative, nonspore-forming, highly pleomorphic bacteria that can present as cocci(0.1 m in diameter), rods (1-4 m long), or thread-like (10 m long). A characteristic feature of the rickettsiae is that they all multiply in an arthropod (lice, ticks, fleas, or mites) as part of their life cycle.

During drug development, tissue samples serve as indicators of disease activity and pharmacodynamic responses. Reliable non-invasive measures of drug target engagement will facilitate identification.

The lone star tick, Amblyomma americanum, is a vector of Ehrlichia chaffeensis and E. ewingii, causal agents of hu- man ehrlichiosis, and has demonstrated marked geograph – ic expansion in recent years. A. americanum ticks often outnumber the vector of Lyme disease, Ixodes scapularis, where both ticks are sympatric, yet cases of Lyme disease

Ticks transmit a wide array of pathogens including bacteria, spirochetes, rickettsiae, protozoa and viruses. In the U.S., Lyme and other tick-borne diseases, including spotted fever rickettsioses, anaplasmosis, tularemia, and ehrlichioses, have been increasing for years, with tens-of-thousands of human cases annually.

Spring is coming, and along with it the beginning of home buying season.

Genome analysis of Major Tick and Mite Vectors of Human Pathogens Submitted by Catherine A. Hill on behalf of the Tick and mite genomes consortium 15 december 2010 executive summary ticks and mites (subphylum Chelicerata: class Acari) transmit a greater variety of human and animal pathogens than any other arthropod vector.
