[Equipping the bacteriological laboratories of a tuberculosis service as the most important element of assurance of the quality and safety of their work].

By taking into account the present requirements for the equipping of the laboratories, the authors have drawn up the minimum standard list of equipment, as well as a list of additional equipment for the specialized bacteriological laboratory of a tuberculosis-controlling institution, which performs microbiological studies for the diagnosis and control of chemotherapy for tuberculosis. The specifications and characteristics of the baric types of equipment used to fit out the laboratories under the present conditions are described. Equipping the laboratories in accordance with the draw-up lists is shown to ensure a qualitative, effective, and safe work.

[Reactivity, immunogenicity and epidemiological effectiveness of vaccination according to various schemes of immunization against whooping-cough, diphtheria and tetanus].

An extended controlled epidemiological trial was carried out for the purpose of studying the reactogenic properties, immunological and epidemiological efficacy of immunization against whooping cough, diphtheria and tetanus according to a scheme suggested by the authors (AKdeltaC-AKdeltaC-KB) in comparison with the official scheme (AKdeltaC-AKdeltaC-AKdeltaC). There was revealed some increase in the frequency of general reactions in children vaccinated by the experimental scheme; however strong general reactions and local reactions of different intensity were encountered with equal frequency in both groups. Two months after the end of the vaccination significantly higher titres of pertussis agglutinins were revealed in children immunized by the AKdeltaC-AKdeltaC-KB scheme; no significant difference was found in the content of the protective titres of diphtheria and tetanus antitoxins.
