An epidemiological investigation on pathogens of diarrhoeal diseases in Ning Xia was reported. Eight genus of agents were found in all stool specimens of persons with detectable rate of 41.16%. Moreover, the most prevalent pathogens were shigella (19.59%), followed by rotaviruses (10.07%), salmonella (4.76%), and entero-pathogenic Escherichia coli (4.20%). Four of them accounted for 93.85% of detectable agents. In addition, in shigella B group made up 80.44%, and 2a was the predominant agent. Similarly S. typhimurium accounted for 85.71% in salmonella. The detectable rates in different age groups ranged from 27.21% to 59.89%. It was was lower in the groups under one year and over fifty and highest (59.89%) in the groups aged 20-49. Regarding seasonal variation, the detectable rate fluctuated from 31.25-50.13%, and the highest prevalence was obtained in autumn, whereas the lowest in the winter. Besides, the most commonly found agent in any seasons was shigella. In spring and autumn rotavirus was more frequently found. This study revealed that there were no significant differences between male and female, Hui and Han people, or urban and rural areas in detectable rates of agents.
