[Clinical and epidemiological characteristics of marseilles (mediterranean tick-borne) fever in the Crimea Autonomous Republic].

In the paper, new data are submitted on natural focality of Marseilles fever in the territory of the Crimean Peninsula. Identified in the above territory was a high activity of previously unknown natural foci that manifested themselves by an epidemic outbreak (Saki, 1996) and by sporadic diseases in people. A clinical-and-epidemiological characterization is given of rickettsiosis in the Crimea Autonomous Republic.

[An indirect hemagglutinin test for Rickettsia prowazekii cultivated by the Weigl method].

The technology of preparing of a new ready for use diagnosticum for IHAT on the basis of polysaccharide of Rickettsia prowazekii cultivated by the Weight method has been developed. Technological conditions have been worked out, experimental series of the diagnosticum have been made and tested, high stability during the storage was confirmed which allows it to be recommended for the epidemic typhus laboratory diagnostics.

[The characteristics of the spread of Coxiella burnetii in the Carpathian region].

The paper presents data of the long-term (1975-1994) study of Q fever in Carpathian region [correction of Forecarpathia] (Ivano-Frankivs'k and Chernivtsi provinces) and dynamics of epidemiologic manifestations of this disease during the recent years. It is shown that after Q fever outbreaks in 1975-1977, people sick for it have been recorded sporadically, and a considerable decrease of epidemiological manifestations of Coxiella burnetii circulation is observed in the late years. This is accompanied by the decrease of the immune stratum among the population from 10.

[Current problems in the laboratory control of louse-borne typhus infection in Ukraine].

Surveys designed to study spread of typhus infection (persistent form and Brill's disease), and state of laboratory diagnosis in Ukraine showed an important role the laboratory diagnosis plays in the system of epidemiological surveillance aimed at preventing epidemic typhus. Main trends of activities on perfection of the system of laboratory control of the infection under present-day conditions are outlined.

[The status of epidemiological surveillance in rickettsioses in Ukraine].

A multi-annual study of rickettsiosis in the Ukraine is presented which included Brill's disease, Q-fever, Volyn fever. The status of epidemiological surveillance is outlined. Ways of perfection of the surveillance system are described.

[The diagnosis of rickettsioses in patients under therapy].

A serological study of 92 patients with rickettsiosis, revealed in the blood serum of 19 patients antibodies to the pathogens of Q-fever or typhoid fever. In three patients the character of distribution of immunoglobulins of different classes corresponded to the chronic course of rickettsia infection. Patients of the therapeutic profile from infections foci should be examined for rickettsiosis.
