Isolates of Salmonella in Liguria from 2008 to 2009

The ENTER-NET project is coordinated by the Istituto Superiore di Sanità (ISS) and includes Hospital and University loboratories from different areas of the country. This project has the aim to study the emergence and the spread of Salmonella app. isolated at a national level and to evaluate their antibiotic resitance. In the period 2008-2009 the Bacteriological Laboratory of Genoa University Department of Health Sciences (DISSAL) collected and confirmed every year about 100 Salmonella specimens isolated by ARPAL (Azienda Regionale Protezione Ambiente Ligure) laboratories and coming from peripheral ligurian hospital laboratories. Over 204 cases of 2008-2009 period, the 50.98% had not a human origin, the 20.19% of which came from food and the 79.81% from surface streams. The remaining 49.02% were of human origin and the 65% was represented by the serotype S. typhimurium (mostly from hospitalized under 14 years old children) while S. enteritidis (12%) was mostly collected from adult hospitalized subjects and did not present pluri-resistance. Between non-human serotypes a strain of S. bredeney, isolated from a sample of raw lamb meat in 2009, was resistant to 8 antibiotics including Chloramphenicol (CAF), Tetracycline, Ampicillin, Trimethoprim and Sulfometoxazol while a strain of S. typhymurium (from a sample of sea water) was resistant to the same last antibiotics and to the Clavulanic Acid-Amoxicillin association.
