Abstract Abstract: The paper aim to investigate the prevalence and resistant pattern of salmonella associated with acute bacterial infectious diarrhoetic children. Stool specimens were collected from outpatients and inpatients with actue bacterial diarrhea admitted by the children’s Hospital of Fudan University during July 1 to September 30 in 2010 to do the salmonella culture by isolated method. Antimicrobial susceptibility was tested by Kirby Bauer method. Total 1045 patients suffered from actue bacterial infectious diarrhea were submitted to this investigation. Out of 160 patients were infected with salmonella.The infection rate was 15.3%(160/1045). The infection rate was 23.6%(119/505) in the group less than 1 year old, which was significant higher than that in the group of 1 to 5 years old (7.6%,32/423), and in the group of great than 5 years old (7.7%,9/117)(x2=2090,p<0.001). Total 21 serum types of salmonella were found,among them, Salmonella Typhimurium rate was 40.6%(65/160), Salmonella Enteritidis rate was 25.0%(40/160),the others was 34.4%(55/160).The resistance rates of Salmonella Typhimrium and Salmonella Enteritidis to Ampicillin were 91.4% and 69.0%,the resistant rates to ceftriaxone were 15.0%,29.3%, and the resistant rates to Cefotaxime were 29.3%,12.5%,respectively.The sensitivity rates of Salmonella Typhimuriumand Salmonella Enteritidis to Cefperazone/sulbactam,Cefmetazole,and Fosfomucin were higher than 90% respectively. These resuls suggest that the Salmonella was priority pathogenic bacteria associated with acute bacterial infeictious diarrhoetic children in our hospital in the summer time in 2010. Aged less than 1 year wrer sussceptible population to Salmonella infection.The prevalence serum types were Salmonella Typhimurium and Salmonella Enteritidis,which hanve appeared different range of resistance to the third generation cephalosporin.
