[Results of an epidemiological study of familial foci of salmonellosis in the Western Urals]. / Rezul'taty épidemiologicheskogo izucheniia semeinykh ochagov sal'monelleza na Zapadnom Urale.

The study of 449 family foci of salmonellosis demonstrated the possibility of detecting cases of salmonellosis, not diagnosed by clinical and bacteriological methods, in the passive hemagglutination test. Such undetected Salmonella carriers, not observing the rules of personal hygiene, contributed to the contamination of household articles, foodstuffs and the environment. The formation of the family foci of salmonellosis was facilitated by the belated detection and hospitalization of salmonelloses cases, as well as by the inadequate observance of the rules for infant care and feeding.
