Recent trends in salmonellosis epidemiology

The taxonomy of the genus Salmonella and the recent trends in the epidemiology of salmonellosis have been reviewed. Global and Italian trends in salmonellae infections have been considered focusing on the application of molecular biology methods to the study of epidemic isolates, as in the case of S. Wien and the more recent S. Enteritidis pandemics. Interventions for salmonellosis prevention, and control measures including new rapid cultural methods for the detection of salmonellae in foods, have been summarized.
