La toxi-infection alimentaire
ABSTRACT Current increase in the incidence of foodborne disease outbreak in developped countries is mainly due to salmonella, especially Salmonella Enteritidis over the five last years. From environmental sources, these bacteria can originate contamination of untreated foods like eggs, meats, shellfish, as well as every link of the food chain. Most foodborne disease outbreaks due to salmonella are associated with food prepared at home. Infection results in acute but mild gastroenteritis, except in newborn and elderly patients whose death-to-case ratio is higher, especially in hospital or institution. Early epidemiological survey must be performed in every foodborne disease outbreak. Clinical, bacteriological and food data have to be carefully collected, for a computer assisted analysis. When implicated pathogen, food vehicle, source of contamination and contributing factors are identified, control measures are immediately taken to prevent recurrences. Systematic reporting of foodborne disease outbreaks is compulsory in order to implement a national epidemiological surveillance.

ABSTRACT: This descriptive epidemiological study is based on 308 cases (139 women and 169 men) and 317 Salmonella strainsisolated during 39 months. An average of 95 Salmonella were isolated each year in the microbiology laboratory of the Guadeloupe University Hospital (total population: 407,000). The patients in this study were mostly young; 29.2% were under 1 year, 27.3% between 2 and 10, and 70 to 75% were under 30 years of age. The sex ratio was 1.22. No significant difference in the number of the isolates was noticed, even though an increase of Salmonella strains is described during the months of June, July and September. The most frequently isolated Salmonella serotypes were: S. enteritidis (40.1%), S. panama (15.5%), and S. typhimurium (9.8%). S. panama caused an unexpected infectious problem in the archipelago. In the same way, S. cerro and S. Kisangani were more frequently isolated in this study than in any other. Stool examination was the most common for Salmonella diagnosis, furthermore bacteremia rate (19.6%) and positive cerebrospinal fluid (CSF) culture (5/317) were among the most important ever reported.MÃ©decine et Maladies Infectieuses 05/1998; 28(5):418-422.

ABSTRACT: A retrospective study of the antibiotic susceptibility of Salmonellae and Shigellae isolated in France during 1994 was carried out by the Collège de Bactériologie, Virologie et Hygiène des Hôpitaux de France. The results of 2 800 susceptibility tests were provided by 76 centres representative of the french territory. This study reveals the frequency of high-level resistance among certain isolates, such as 1 093 strains of S. typhimurium to aminopenicillins, tetracyclines, chloramphenicol or cotrimoxazole, whereas others, like S. enteritidis (1 016 strains), showed practically no resistance. Some antibiotics can therefore no longer be used as first line therapy against bacteremia due to Salmonella.
