[The aggregation ability of the plague microbe].

Hemoglobin enhances the aggregation of the plague bacillus in fluids (p > 0.99), the proportion of its action on this process being 46.7%.

[Antibiotic sensitivity of plague microbe strains from foreign countries].

The method of serial dilutions on the Hottinger agar was applied to comparative assay of antibiotic sensitivity in 50 strains of the plague microbe isolated abroad and in 5 strains isolated in the plague focus in the Central Caucasus. The antibiotics used in the assay were the following: streptomycin, gentamicin, doxycycline, monomycin, kanamycin, tetracycline, erythromycin, ristomycin, lincomycin and polymyxin M. Irrespective of the origin, all the isolates were resistant to erythromycin, lincomycin and polymyxin M.

[The experimental action of lindane on the vector capacity of plague-infected fleas].

Being fed on white mice, intoxicated with subtoxic doses of lindane, blocked fleas sharply decreased in number. The inhibition of the vector ability of fleas, infected with plague, under the systemic effect of lindane is shown.
