Pseudoclavibacter chungangensis sp. nov., isolated from activated sludge.

The taxonomic position of a Gram-positive, non-spore-forming strain, designated CAU 59(T), from activated sludge was investigated. Colony morphology, biochemical tests and chemotaxonomic investigations revealed that strain CAU 59(T) possessed the characteristics of the genus Pseudoclavibacter. Comparative 16S rRNA gene sequence analysis showed sequence divergence values between strain CAU 59(T) and other described Pseudoclavibacter species of more than 3.

Bacillus chungangensis sp. nov., a halophilic species isolated from sea sand.

The taxonomic position of a Gram-stain-positive, endospore-forming, halophilic strain, designated CAU 348(T), isolated from sea sand was investigated using a polyphasic approach. Colony morphology, biochemical tests and chemotaxonomic investigations revealed that strain CAU 348(T) had the characteristics of the genus Bacillus. Comparative 16S rRNA gene sequence analysis showed that the organism formed a hitherto unknown subline within the genus Bacillus.

Corynebacterium doosanense sp. nov., isolated from activated sludge.

The taxonomic position of a Gram-positive, non-motile, non-spore-forming coryneform, isolated from activated sludge and designated strain CAU 212(T), was investigated using a polyphasic approach. Cellular morphology, biochemical tests and chemotaxonomic investigations revealed that strain CAU 212(T) had the characteristics of the genus Corynebacterium. Comparative 16S rRNA gene sequence analysis showed that the organism formed a hitherto-unknown subline within the genus Corynebacterium.

Lactococcus chungangensis sp. nov., a lactic acid bacterium isolated from activated sludge foam.

The taxonomic position of a Gram-positive coccus, designated strain CAU 28T, isolated from activated sludge foam was determined by using a polyphasic approach. Based on its cellular morphology and the results of biochemical tests, strain CAU 28T was identified tentatively as a member of the genus Lactococcus. Comparative 16S rRNA gene sequence analysis showed that levels of similarity between strain CAU 28T and the type strains of recognized Lactococcus species ranged from 90.

Glycosyltransferase: a specific marker for the discrimination of Bacillus anthracis from the Bacillus cereus group.

Bacillus anthracis, the aetiological agent of anthrax, has been taxonomically classified with the Bacillus cereus group, which comprises B. cereus, Bacillus thuringiensis, Bacillus mycoides, Bacillus pseudomycoides and Bacillus weihenstephanensis. Although the pathogenesis and ecological manifestations may be different, B.

Detection of unusual rotavirus genotypes G8P[8] and G12P[6] in South Korea.

Five hundred four fecal specimens, collected between 2004 and 2006 from young children with acute diarrhea, were screened for rotavirus by ELISA with VP6-specific antibody. Of these samples, 394 (78.2%) were confirmed as group A rotavirus and they underwent G- and P typing using a combination of ELISA, RT-PCR, and sequence analysis methods.
