[Lactic acid bacteria and streptococci of the human stomach normally and in pathological processes].

Lactic acid bacteria were either absent or present in negligent quantities in the stomach of apparently healthy man. But in case of various pathological processes in the stomach and duodenum lactic acid bacteria accumulated (up to a million cells per 1 ml of gastric contents). Under these conditions coccal forms sharply prevailed over the bacillary ones. In patients with chronic gastritis and peptic ulcer of the stomach the most frequent were Streptococcus faecalis and its variants; in oncological patients--Str. faecium, strains affiliated to Leuconostoc mesenteroides, and sometimes Str. durans.

[Nocardia asteroides (Eppinger) Blanchard in the soils of the Ukrainian SSR].

The distribution of Nocardia asteroides (Eppinger) Blanchard, the main causative agent of nocardiosis in humans and animals, in the soils of the Ukrainian SSR was studied. This species was found to inhabit cultivated soils in various soil-climatic zones of the Ukrainian SSR. The isolated strains proved to be heterogeneous in their properties. N. asteroides fell into 2 groups: acetamidase-negative (A) and acetamidase-positive (B). Newly isolated N. asteroides belonging to the acetamidase-positive group were shown to be always pathogenic, whereas the organisms of the acetamidase-negative group could be pathogenic and non-pathogenic in white mice.
