Increased burden of illness associated with antimicrobial-resistant Salmonella enterica serotype typhimurium infections.
resistance rates of Salmonella enterica strains isolated from children of two Southern European countries. The study included 9527 (2096 Italian and 7431 Spanish) children (median age: 3.0 years; range: 7 days to 19.2 years) admitted for acute diarrhoea to the Department of Paediatrics, University of Florence, Italy, and the Hospital Valle d’Hebron, Barcelona, Spain, from January 1, 1997 to December 31, 2003. Salmonella enterica strains were isolated from stool cultures in 1267 of the 9527 children (13.3%) admitted for treatment; antibiotic susceptibility tests were performed on 973 of these 1267 children (76.8%) using the Kirby-Bauer method . The χ for trend test was used to compare categoric variables. A p value <0.05 was considered to be statistically significant. M. Cellai Rustici . F. Mangiantini . E. Chiappini .
