The occurrence of Clostridium difficile in faecal specimens of 218 children, aged 2 weeks to 15 years, was studied. The organism was recovered from 43 (20%) of the children (range 2 weeks to 10 years). The isolation frequency was significantly correlated to age. Thus, in children 1 to 8 months of age the organism occurred in 64%, while in children below and above that age C. difficile could only be recovered in 4%. No significant difference in the recovery frequency could be demonstrated between children with (23%) and without (17%) gastroenteritis. C. difficile occurred numerically more often in non-antibiotic treated children (22%) than in those given such drugs (13%). None of the children in the present study had evidence of pseudomembranous colitis. A comparative study of different selective media did not demonstrate any difference in the recovery frequency of C. difficile. The media used were Chopped Meat Glucose broth with cycloserine and either kanamycin or cefoxitin, and Cycloserine-Cefoxitin-Fructose agar.

The aim of this work was to investigate the presence of Salmonella spp. in 300 beef meat samples collected from cattle carcasses of different categories (young bulls, culled heifers and culled cows). The detection of Salmonella spp. was performed by the alternative VIDAS Easy Salmonella technique and confirmed by PCR using Salmonella specific primers. Salmonella serotypes were determined by slide agglutination tests. The resistance to 12 antibiotics was determined by the diffusion method on Mueller-Hinton agar antibiotic discs. The overall contamination rate of beef by Salmonella spp. was 5.7% (17/300). This rate varied from naught (0/100) in bulls' meat to 14% (14/100) in culled cows' meat (p<0.001). The prevalence of Salmonella spp. was higher in summer and in cattle with digestive disorders: chronic gastroenteritis (6/17), traumatic peritonitis (3/17) and intestinal obstruction (2/17) (p<0.0001). Of the 17 Salmonella isolates, 6 serotypes were identified, namely Salmonella Montevideo (8/17), Salmonella Anatum (3/17), Salmonella Minnesota (2/17), Salmonella Amsterdam (2/17), Salmonella Kentucky (1/17) and Salmonella Brandenburg (1/17) (p<0.05). Unlike other serotypes, S. Montevideo was present during the whole year except winter. Almost all of the strains (16/17) were resistant to at least one of the 12 tested antibiotics. Multidrug-resistance concerned 14/17 of the strains, including Amoxicillin (13/17), Tetracycline (12/17), Streptomycin (10/17) and Nalidixic acid (6/17). All the strains were sensitive to the association (Amoxicillin+Clavulanic acid), Cefoxitin and Ceftazidime. In addition, our study showed that all Salmonella strains (17) were positive for invasion gene invA and negative for the virulence gene spvC. Only one isolate (S. Kentucky) harbored the h-li virulence gene.
