A total of 29 strains mainly from guinea pigs were investigated by a polyphasic approach that included previously published data. The strains were classified as Bisgaard taxa 5 and 7 by comparison of phenotypic characteristics and the strains showed typical cultural characteristics for members of family Pasteurellaceae and the strains formed two monophyletic groups based on 16S rRNA gene sequence comparison. Partial rpoB sequence analysis as well as published data on DNA-DNA hybridization showed high genotypic relationships within both groups...

A Gram-stain-negative, facultatively aerobic, motile-by-gliding, non-flagellated and rod-shaped bacterial strain, designated YSM-43T, was isolated from a tidal flat in Yeosu on the South Sea in the Republic of Korea. Strain YSM-43T grew optimally at 30 °C and in the presence of 1.0-2.0 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain YSM-43T fell within the clade comprising type strains of Flavobacterium species, clustering with the type strains of Flavobacterium jejuense and Flavobacterium jumunjinense...

Chicory (Cichorium intybus) is a perennial plant (Asteraceae) that grows wild in pasture fields in Saudi Arabia. Chicory plants displaying symptoms typically induced by phytoplasmas, such as bushy phenotype and stunt, were observed in the Mulayda region, Qassim governorate, Saudi Arabia. In this study we examined samples taken from three symptomatic chicory plants and confirmed the presence of phytoplasma DNA. Analysis of the 16S rRNA-encoding sequences showed that the plants were infected with a phytoplasma from the pigeon pea witches'-broom group (16SrIX)...

In our previous study based on hsp60 PCR-restriction fragment length polymorphism and 16S rRNA gene sequencing, we stated that the bifidobacterial strains isolated from the individual faecal samples of five baby common marmosets constituted different phylogenetically isolated groups of the genus Bifidobacterium. In that study, we also proposed that these isolated groups potentially represented novel species of the genus Bifidobacterium. Out of them, Bifidobacterium aesculapii, Bifidobacterium myosotis, Bifidobacterium tissieri and Bifidobacterium hapali, have been described recently...
