title: [Epidemic occurrence of alimentary bacterial infections in the Czech Republic 1979-1989].
abstract: The authors analyze the epidemic incidence of alimentary infections of bacterial origin in two periods: 1979-1983 and 1984-1988 and 1989 resp., where in each period the number of notified epidemics of different infections equals 100%. During the period 1984-1988 as compared with 1979-1983, there was a decline in the number of epidemics of salmonelloses in health institutions from 42% to 14%, whereby almost half these epidemics were caused by Salmonella agona spread via dried milk. Conversely there was an increase in the number of epidemics of salmonelloses in communities from 14% to 23% and in works canteens from 9% to 14%. In 68% of the latter Salmonella enteritidis dominated. In 1989 there was a potent increase epidemics of salmonelloses. In 86% of the notified epidemics Salmonella enteritidis was the aetiological agent. A quarter of these epidemics developed in works canteens and half the affected subjects were ill. The transmission occurred via poultry meat and egg products. The annual incidence of bacillary dysentery after 1985 has a declining trend, the epidemics persist in nursery schools, summer camps for children and are increasing in institutes for social care. The number of alimentary intoxications is rising in recent years, in particular in school and works canteens. The number of 008 epidemics in 1984-1988 declined in health institutions from 52% to 20%. 17% of the epidemics developed in schools and camps for children.
