[Sensitivity of Helicobacter pylori to antibacterial drug preparations in potential military recruits with duodenal peptic ulcer].

Results are submitted of bacteriological investigations in those persons with duodenal peptic ulcer who had been called up. The presence of regional strains of H. pylori is ascertained together with their sensitivity to certain antibacterial drug preparations.

Specific identification of Mycobacterium bovis by monoclonal antibody-based enzyme immunoassay.

To improve identification of M. bovis, rabbit immune sera and mouse monoclonal antibodies against M. bovis-secreted protein antigens were used in the enzyme-linked assay (ELISA).

[A chamber for microorganism microcultivation with microscopic monitoring].

A new chamber for microorganism microcultivation with microscopic monitoring has been developed and tried. It is not only fit for microcultivation of various microorganism species but is characterized by a number of advantages over the known chambers as well.

[A new method of cultivating Mycobacterium tuberculosis].

The possibility is shown of microcultivation of Mycobacteria tuberculosis on semipermeable cellophane membranes covering solid nutrients. The new method of cultivation may be used for enhanced microbiological diagnosis of tuberculosis, for determination of drug resistance of the tuberculous pathogen as well as for assessment of the biological properties of Mycobacteria tuberculosis in live unstained culture.

[Microscopic method of the determination of Mycobacterium tuberculosis sensitivity to chemotherapeutic agents].

A microscopic method of testing M. tuberculosis sensitivity to chemotherapeutic drugs was developed and tried out. According to it, M.
