[The phenotypic properties of freshly isolated strains of Bordetella].

As the result of our investigations, newly isolated B. pertussis and B. bronchiseptica strains were studied.

[The results of a comparative study of different series of commercial casein-carbon agar].

Comparative assessment of the diagnostic properties of 30 lots of commercial casein-carbon agar used in practical bacteriology for the diagnosis of pertussis has shown essential differences in the efficacies of various lots of this medium. Only 11 of the 30 tested lots provided the formation of B. pertussis colonies in the periods established by the instruction.

[Cytoarchitectonics of lymph node parenchyma during exposure to increased pressure].

Quantitative relations between the lymphoid tissue cells in various zones of the popliteal lymph node were stated in mice kept in the barochamber under pressure of 3 atm for 0.5, 1, 2, 4 and 6 days. Decreasing number of small lymphocytes and reticular cells was observed.
