[Characteristics of bacterial excretion in pulmonary tuberculosis patients residents of the Yakut region]. / Kharakteristika bakteriovydeleniia u bol'nykh tuberkulezom legkikh--zhitelei Iakutii.

The present state of bacilli excretion in the Yakut area and its certain social aspects are characterized, the detection rate of M. tuberculosis in pulmonary tuberculosis and the sex-age structure are subjected to analysis. Data on the primary and secondary drug resistance, type appertainance of the causative agent and the result of a disinfectant work in the infection foci have been studied in 511 patients having copious bacilli excretion.

[Bacteriologic examination for tuberculosis in subjects from a group at risk]. / Bakteriologicheskoe obsledovanie na tuberkulez lits iz grupp riska.

Laboratory methods were used to test the samples taken from 55,068 people for M. tuberculosis. Inoculation of diagnostic material for M. tuberculosis was accompanied in a number of cases by a parallel method of luminescent microscopy for the same purpose. Methods of examining the patients with non-specific lung and genitourinary diseases were developed. They consist in a preliminary step-by-step selection of diagnostic material by means of luminescent microscopy and the use of these rapid techniques, like indicator strips, making it possible to examine a great number of population within a short period of time. The expenses of step-by-step laboratory examination of risk group subjects are 4.8 times lower than those incurred with routine methods of bacteriological screening.

[Microbiologic oxidation of diesel fuel by the total factor experiment method]. / Izuchenie mikrobiologicheskogo okisleniia dizel'nogo topliva metodom polnogo faktornogo éksperimenta.

The effect of nitrogen, phosphorus, glucose and temperature on the assimilation of diesel fuel and the biomass yield of Mycobacterium mucosum was studied by the method of complete factor experiment. The concentration of nitrogen and phosphorus were shown to be most important for the above processes. The growth dynamics of the culture was studied as well as the utilization by it of diesel fuel and glucose added to the medium separately or in combination. The presence of glucose in the medium had no effect on the utilization of diesel fuel; however, the utilization of glucose in the presence of diesel fuel was considerably decelerated.
