| Abstract: | The diagnostically and in regard to surveillance rather comprehensively recorded salmonellosis bear the character of a model of zoonotic diarrhoeal diseases. Whereas those serovars predominantly adapted to human beings or animal species are without any importance in this connection, such serovars with own epizootic processes in different animal species with or without causing illness are able to be transferred to human beings via foods of animal origin and to act as etiological agents of gastroenteritis. Some strains of them equipped by special properties often encoded by plasmids can be transferred from man to man, too. In GDR in 1987 S. enteritidis (34.0%), S. typhimurium (17.9%), S. manhattan (7.7%) and S. agona (7.4%) amounted to two thirds of all the salmonella isolates in connection with human enteritis. For analyzing epizootic-epidemic processes in the case of rare serovars the identity of serovars is sufficient in first approximation, in the case of frequently isolated serovars the complex typing of the concerned strains by using epidemiological laboratory methods is required. |
