[Non-typhoid Salmonella in pediatric patients in Tunis (Hospital Charles-Nicolle) from 1980 to 1991].
252 nontyphoidic salmonellae strains isolated from pediatrics were identified by using standard laboratory procedures and were serotyped with commercial antisera. Antibiotic susceptibility tests were performed by the agar diffusion method. Mostly isolates obtained from feces (182) and blood (67) and 89% of them from newborns and nursings. S. sér. Wien represented 75% of the isolates. The other serovars were essentially S. sér Typhimurium, S. sér Infantis and S. sér Enteritidis. All the isolates of S. sér Wien and S. sér Typhimurium were resistant to amoxicillin, carbenicillin, cephalothin, streptomycin, chloramphenicol and tetracycline from 1980. From 1987 S. sér Wien isolates developed resistance to cefotaxime and amikacin. Distribution nontyphoidic salmonellae strains according to the year was variable. Maximal isolates were in September and October. Two major epidemics were observed in this study, in 1982 and 1989. 94% of the strains determined nosocomial infections. The source of infection was established during the epidemic of 1989. The application of hygiene measures led to decline the number of isolates in 1990 and their disappearance in 1991, any strains of S. sér Wien was isolated.
