[The role of day-old chicks in the transmission of Salmonella enteritidis].

The epidemiological analysis of an outbreak of salmonellosis, registered in May 1988 on the territory of two regions of the Karelian ASSR and covering 10 villages, was carried out. Altogether 112 persons were affected. One-day old chickens sold to the population by the local poultry plant were the source of infection which was transmitted through everyday contacts: those persons who had direct contact with chickens were affected. S. enteritidis with similar biological characteristics were isolated from salmonellosis patients, from persons having had contacts with chickens and from chickens. Chickens were probably infected by oral route.
