Abstract: | A retrospective analysis, covering a period of 20 years, of 2049 primo-isolates ofSalmonella typhimurium and 343 primo-isolates ofSalmonella enteritidis was performed at our laboratory. In 1991,S. enteritidis (43.8%) outnumberedS. typhimurium (32.1%) as the most frequently isolated Salmonella. The age group distribution ofS. enteritidis yielded peaks in the under-five and above-60 year age groups, whereasS. typhimurium only peaked in the under-five age group.S. enteritidis appeared to be twice as invasive asS. typhimurium. Both serotypes were more invasive in middle and older age groups than in under-fives. |
