Certain problems in developing the Automated Control System for the "Sanitary-Epidemiologic Service" of the Uzbek SSR

The main difficulties of using the subsystem "Records, Accounts and Analysis of Morbidity in Infectious Diseases", developed by the Republican Information and Computing Center of the Ministry of Health of the Byelorussian SSR for integration into the automated control system, under conditions of the Uzbek SSR lied in the fact that the number of the coupons of Recond Forms 171-BM for computers, several times exceeding that used in the Byelourssian SSR, had to be previously handled manually and in a short time.     

Results of the examination of patients with viral hepatitis for HBsAg in Kashka-Darya Province, Uzbek SSR

The practical use of the reverse passive hemagglutination test for the examination of viral hepatitis patients revealed the presence of HBsAg, on the average, in 28.4 +/- 0.95% of cases. This antigen occurred most frequently among the patients aged up to 1 year (42.8 +/- 4.18%), as well as in the second quarter of the year (33.3 +/- 2.3%). The proportion of patients with hepatitis B in the total number of patients with viral hepatitis was 20%.     

Serovars of nonagglutinating vibrios isolated on the territory of the Uzbek SSR and their role in the development of acute intestinal diseases

As the result of the serotyping of 1,223 NAG vibrio strains isolated in the Uzbek SSR from the environment and 659 strains isolated from gastroenteritis patients and from vibriocarriers, the serovars of 563 strains (46%) and 420 strains (63%), respectively, were determined. The prevailing serovars were 08, 06, 09, 014, 05, 039, 041, 013, 019 among the strains isolated from the environment and 08, 041, 037, 05, 039, 024, 06 among the strains isolated from humans. The strains belonging to serovars 05, 06, 08, 024, 037, 039, 041 were isolated both from the environment and from humans. The possible role of these strains in the development of acute gastroenteritis and in the formation of vibriocarriership in humans is pointed out.     

Study data on ornithosis infection in the Azerbaijan SSR]

Data are presented on the study of epizootology and epidemiology of ornithosis. There were revealed natural foci of ornithosis in the Kyzyl-Agach preserve, at the Sary-Su lakes and at the Glinyany island; these foci were dihostal and polyhostal, as well as conjointed (ornithosis, arboviruses, Q-fever, Asian tick-borne typhus, leptospirosis). Anthropurgic foci were found in 12 populated localities, semi-wild dove serving as the main component. Fowl was found to be infected in 12 poultry-farms; occupational ornithosis was present among the bird-rearers. Immunological structure of the population in respect to ornithosis was studied. Patients with various diagnoses showed positive serological reactions retrospectively; there were 155 cases of ornithosis among them.     

Meningococcal plasmids

In Neisseria meningitidis strains isolated from patients with meningococcal infection and from carriers, the presence of plasmids has been detected by the modified method of H. C. Bernboim and J. Doly. The strains have been studied with respect to their pathogenicity and sensitivity to antibacterial substances. No correlation between the presence of plasmids and pathogenicity factors, such as antilysozyme activity, the presence of hyaluronidase and the positive reaction to Congo red, resistance to penicillin, serogroup and the sources of isolation, has been established.
