A waste stabilization pond was suspected of causing fecal contamination to Holt Branch, a tributary of Juniper Creek, near Byron, Georgia. We used ribotyping, a genotypic (DNA-based) bacterial source tracking (BST) method, to match Enterococcus faecalis isolates from Holt Branch and the waste stabilization pond. Fecal enterococci in the effluent from the waste stabilization pond averaged 13,863...
conclusions the results of pcr-ribotyping indicate that no relationship exists between clinical and meat isolates. we therefore conclude that other sources than meat may function as a vector for ca-cdi. results the overall prevalence of c. difficile with two toxigenic genes including tcda and tcdb was estimated at 4.0%. c. difficile was detected in 2.8%, 2.1%, 3.6% and 6.2% of chopped beef, gro...
A collection of Salmonella enterica serotype Typhimurium human strains isolated in Northern Sardinia (Italy) was examined for the insertion sequence IS200, phage type, antibiotic profile, ribotyping polymorphisms and plasmid profile. All clinical isolates studied contained from 4 to 10 copies of the IS200 element. IS200 permitted to discriminate Typhimurium strains and to identify five IS200 ty...
The aim of this study was to identify the strengths and weaknesses of five DNA fingerprint methods for epidemiological typing of Streptococcus pneumoniae. We investigated the usefulness of (i) ribotyping, (ii) BOX fingerprinting with the BOX repetitive sequence of S. pneumoniae as a DNA probe, (iii) PCR fingerprinting with a primer homologous to the enterobacterial repetitive intergenic consens...
