چکیده

Strains from anal swabs and chronic otitis externa in dogs were shown to be phylogenetically related to the Enterococcus faecium species group. They shared a number of phenotypic characteristics with these species, but they could be easily differentiated by biochemical reactions. In addition, the canine strains were unusual in their nearly complete failure to grow on sodium azide-containing enterococci-selective media and in their Voges-Proskauer reactions (usually negative). By using 16S rRNA sequencing and DNA-DNA hybridization of representative strains, as well as tDNA interspacer gene PCR and SDS-PAGE of whole-cell proteins, the group of canine strains was shown to constitute a novel enterococcal species. The name Enterococcus canis sp. nov. is proposed for this species, with LMG 12316T (= CCUG 46666T) as the type strain. Concurrently, the taxonomic situation and nomenclatural position of Enterococcus porcinus were investigated. As no phenotypic or genotypic differences were found between this species and Enterococcus villorum, the name E. porcinus is considered to be a junior synonym of E. villorum.

Enterococcus haemoperoxidus sp. nov. and Enterococcus moraviensis sp. nov., isolated from water.

A polyphasic taxonomic approach was used to study atypical enterococci isolated from surface waters. All strains were characterized by physiological and biochemical tests as well as by genotyping. The results of biochemical tests and tRNA intergenic length polymorphism analysis (tDNA-PCR) divided all studied strains uniformly into two groups. Because these groups were clearly separated from all...

Enterococcus silesiacus sp. nov. and Enterococcus termitis sp. nov.

Three enterococci constituted two aberrant branches after numerical analysis of (GTG)5-PCR fingerprints: analogous patterns were found for two water isolates, strains W213 and W442T, and a separate position was found for an isolate from the gut of a termite, strain LMG 8895T. 16S rRNA gene sequence analysis classified all three strains in the Enterococcus faecalis species group. Further sequenc...

Enterococcus aquimarinus sp. nov., isolated from sea water.

Two enterococcal strains LMG 16607(T) and LMG 16612 originating from sea water were analysed in a polyphasic taxonomic study. Both strains, assigned as Enterococcus sp. in the BCCM/LMG culture collection, possessed analogous protein profiles, but these were different from all other enterococcal species. 16S rRNA gene sequence analysis of one strain showed the highest similarity, 96.9-96.1%, wit...
