Tick-borne relapsing fever tick

Return spirochetosis (endemic BT) is a group of infectious diseases, agents which are different types of spirochetes belonging to the genus Borrelia.

Epidemic relapsing fever Relapsing fever

lousy or relapsing fever - is a serious infectious disease that is accompanied by fever attacks and periods of normalization of body temperature.

causative agent of relapsing fever epidemic form is Obermeyer pallidum, which is found in the blood of patients at the time of the attack.Sick people - is the main source of infection.Carrier of relapsing fever this form - Hanging louse (sometimes pubic and head).Infection occurs when damage to the body lice and hit the hemolymph of the infected carrier relapsing fever on damaged skin (bites or scratches).Susceptibility to disease - one hundred percent.This infection is common in countries with very poor sanitary conditions of the population.
