Mediterranean Spotted Fever and Other Tick-Borne Rickettsioses

摘要: Rickettsioses are arthropod-borne infections caused by bacteria belonging to the genus Rickettsia within family Rickettsiaceae in order Rickettsiales. Most of these zoonoses transmitted ticks, but some vectored lice, fleas, or mites. Tick-borne rickettsioses have specific geographic distributions, directly dependent on distribution their vectors. These among oldest known diseases. Rocky Mountain spotted fever (RMSF) was first reported 1899 Maxcey; its vector, Dermacentor andersoni, described 1909. One year later, Conor and Bruch Mediterranean (MSF) Tunisia. Over last 12 years, another 10 been characterized, including Astrakhan fever, Flinders Island (FISF), African tick-bite (ATBF), Japanese (JSF), tick-borne lymphadenitis (TIBOLA), lymphangitis-associated rickettsiosis (LAR) due sibirica mongolotimonae, unnamed helvetica, aeschlimannii, parkeri, “Rickettsia heilongjiangensis.” Thus, many considered be emerging infections. This chapter considers various aspects rickettsioses, description rickettsiae, vectors relationships between rickettsiae an overview diseases recognized date, a unknown pathogenicity, report modern diagnostic tools treatments used for tick-transmitted rickettsioses.
