A vanG-type locus in Clostridium argentinense

Finished Whole-Genome Sequence of Clostridium argentinense Producing Botulinum Neurotoxin Type G

Here, we present a closed genome sequence for Clostridium argentinense strain 89G, the first strain identified to produce botulinum neurotoxin type G (BoNT/G). Although discovered in 1970, to date, there have been no reference quality sequences publicly available for this species.

VanG-type vancomycin-resistant Enterococcus faecalis strains isolated in Canada.

Enterococcus faecalis G1-0247 (vancomycin MIC, 16 microg/ml) was found to harbor a vanG operon 99% identical to the vanG operon in E. faecalis BM4518. E. faecalis N03-0233 (vancomycin MIC, 16 microg/ml) was found to harbor a novel vanG operon, vanG2, on an element in a different chromosomal location than the vanG-harboring elements in G1-0247 and BM4518.

Organization of the plasmid cpe Locus in Clostridium perfringens type A isolates.

Clostridium perfringens type A isolates causing food poisoning have a chromosomal enterotoxin gene (cpe), while C. perfringens type A isolates responsible for non-food-borne human gastrointestinal diseases carry a plasmid cpe gene. In the present study, the plasmid cpe locus of the type A non-food-borne-disease isolate F4969 was sequenced to design primers and probes for comparative PCR and Sou...
