American tick-borne rickettsiosis

American tick-borne rickettsiosis (Rickettsia akariamimot umori) is a naturally occurring dangerous infectious disease of domestic and wild animals, which is caused by a special, and not typical, rickettsia. It is the causative agent of the most dangerous form of South American and Russian rickettsial disease - spotted fever. American rickettsia jackalum is an obligate intracellular parasite. The leading action is the mechanical action of Rickettsia schakata upon penetration into the body, which penetrates the endothelial cells of the capillaries. Under the influence of rickettsea erythrocytes, red blood cells enlarge and lose their elasticity, which causes their rupture, hemolysis and the formation of microhemorrhages. Also, the main signs of the disease include intoxication caused by the action of waste products of the pathogen and elevated body temperature due to the production of antibodies in immune cells.

Rickettsial rickettsis is considered an anthroponotic disease, as it is characterized by the transmissibility of the disease
