Abstract
As a part of three-years epidemiological survey of salmonellosis in South Kanara District, a southwest coastal region of India, an attempt was made to determine the human Salmonella carriage rate during the period between 1981 to 1983. One thousand and two asymptomatic school children 5 to 15 years of age, 42 restaurant employees and 17 dairy workers formed the subjects of this bacteriological study. The Salmonella carriage rate among healthy school children from a single fecal sampling was 1% and no Salmonellae were recovered from the feces of restaurant and dairy workers. Ten school children excreted Salmonellae which belonged to 6 different serotypes-Salmonella oslo, S. ohio, S. typhimurium, S. urbana, S. cerro and S. derby; S. oslo and S. ohio were the most frequent serotypes. No-S. typhi, S. paratyphi A or S. paratyphi B were recovered. All Salmonella strains recovered during this study were dual or multiple drug resistant, sulfadiazine and tetracycline resistance being commonly observed. The significance of excretion of potentially pathogenic, drug resistant Salmonellae by symptomless school children is discussed from public health point of view.
