[Antagonistic and insecticidal properties of soil micromycetes]. / Antagonisticheskie i insektitsidnye svoistva pochvennykh mikromitsetov.

It was shown that microscopic fungi isolated in plague foci had an antagonistic effect on the plague causative agent. In the majority of the cases it was associated with their insecticidal activity against plague-transmitting fleas. It is expedient to consider the relations revealed between the burrow biocenosis components in investigation of plague enzootic aspects and development of new biological insecticides for control of the infection carriers.

[Detection of L forms of Vibrio cholerae in the water of open water reservoirs]. / Obnaruzhenie L-form kholernykh Vibrionov v vode otkrytogo vodoema.

L-forms of cholera vibrios were isolated from the river water for the first time. The presence of L-forms in water permitted to suppose that such variants served as one of the forms of cholera causative agent preservation in the external medium.

[Cholerogenicity of L-forms of cholera vibrios]. / Izuchenie kholerogennosti L-form kholernykh vibrionov

Dutta and Habbu's method was applied to comparative study of cholerogenic properties of the L-strains of cholera vibrios and their initial bacterial variants. In difference from the initial strains, L-forms of cholera vibrios possessed no cholerogenic properties. A possibility of reversion of the stable L-form of cholera vibrios into bacterial form in vivo was revealed. This reversion was accompanied by the restoration of the cholerogenic properties and the change of the biotype of the cholera vibrio.
