The rickettsiosis is the infectious disease of animals and the person caused by rickettsiae that is extends through blood-sicking insects – carriers of an infection.

Symptoms of Rickettsioses:
At people the rickettsiosis is shown in the form of feverish diseases various on weight. At some types of rickettsioses infection is followed by characteristic rash.
Infection with a flea sapropyra happens owing to hit of the infected excrements of fleas on open wounds and the damaged integuments, such as raschesa. The disease incubation interval in this case makes from 5 to 15 days. A characteristic symptom of a flea typhus is emergence on integuments of rash of bright pink color. Rash develops, as a rule, for the 4-5th days of a disease and is shown not only on a trunk or extremities, but also and on a face. Symptoms are similar to a lousy sapropyra, but the disease proceeds much easier.
The Vakulezny rickettsiosis is characterized by an incubation interval from one to two weeks. Approximately one week prior to developing of fever on site of a sting of a tick there is a characteristic consolidation with a bubble in the center which becomes covered by a black scab over time, and a hyperemia zone (rash elements on which when drying dark crusts are formed) around it.
At a disease of a paroxysmal rickettsiosis the incubation interval makes from 7 to 10 days. Symptoms of this type of a rickettsiosis is a fever recurrence. And the consolidations arising on site a sting of the infected tick and rash, as a rule, are not characteristic of a paroxysmal rickettsiosis.
Reasons of Rickettsioses:
Infection with a rickettsiosis steps after stings of mites, or hit in open wounds, and also on mucous membranes, the infected excrements of fleas and louses. In some cases the rickettsiosis can extend through urine, milts or excrements of the infected animals. As a tank for an infection for the majority of types of a rickettsiosis animals, as a rule, wild, in particular rodents as their disease develops asymptomatically act. From the infected animals blood-sicking insects catch and become disease carriers.
In addition for the majority of types of rickettsioses as tanks of an infection also mites of which transmission of infection from generation to generation is characteristic (transovarial transfer of a rickettsiosis) can act. The natural ochagovost of the majority of types of a rickettsiosis is caused by existence in the nature of tanks of an infection. A tank for a number of types of a disease, for example, for a lousy sapropyra, is the person.
Treatment of Rickettsioses:
The main way of treatment of all types of a rickettsiosis, as a rule, is prescription of antibiotics.
