[Evaluation of the effectiveness of the serological methods for the identification of antibodies in patients with tissue ricketsiosis on the territories of a different risk of Rickettsia sibirica infection.].

Cases of tick-borne rickettsiosis in Siberia and the Far East are associated with R. sibirica, the causative agent of Siberian tick typhus (STT). In connection with a sharp reduction in the nomenclature of diagnostic products and an increase in the spectrum of species of founding rickettsiae on the territory of Russia, new approaches to the laboratory verification of diagnoses are needed.

[Clinical and laboratory diagnosis of tick-borne rickettsioses in areas of low risk of infection Rickettsia sibirica.].

For the first time, a comparative description of clinical and laboratory parameters in patients with clinical signs of tick-borne rickettsiosis in a natural focus with a low risk of infection with R. sibirica and circulation of R. raoultii is given, depending on the results of serological verification of the diagnosis.

[The molecular biological methods of express-detection of pathogens in ticks taken way from patients as a basis of preventive therapy of tick transmissible infections.].

The complex molecular biologic study of ticks, took off from people in the Omskii oblast during Spring-Summer periods in 2014-2016 established their infection with agents of tick's transmissive infections and testifies a significant risk of infection of population. The analysis of ticks I. persulcatus established that rate of detection of DNA of borrelia made up to 59,5%, rickettsia - 30.

[Ureaplasma urealyticum and Ureaplasma parvum in etiology of urogenital mixt-infections].

The complex study of 104 vaginal samples from patients with urogenital uroplasmosis was carried out. U. parvum were detected in 67.

[A new drug for serodiagnosis of listeriosis].

Development and introduction into practical public health of new rapid methods for laboratory diagnosis of listeriosis, that will be characterized by a high sensitivity and specificity, is still a pressing problem. Listeriosis erythrocytic diagnosticum developed at the Omsk Research Institute for Natural Focal Infections permits the detection of species-specific antibodies in patients' sera and convalescents after this infection and is characterized by a sufficiently high diagnostic efficacy. Use of this agent appears to hold good promise in the diagnosis of listeriosis in the acute period of the disease, in retrospective diagnosis, and in screening of risk groups.

[Interrelationship between toxigenic and non-toxigenic diphtheria microbes in the epidemic process].

A study of the circulation of toxigenic and nontoxigenic diphtheria bacilli was carried out in several carrier state foci under conditions of a natural course of the epidemic process. There were 2623 persons under observation. A total of 32158 analyses were carried out, and 2271 strains were isolated and studied.
