We report the principal characteristics of 'Anaerococcus mediterraneensis' strain Marseille P2765, a new member of the Anaerococcus genus. Strain Marseille P2765 was isolated in a vaginal sample of a 26-year-old patient with bacterial vaginosis.

We report the principal characteristics of 'Peptoniphilus raoultii' strain KHD4 (= CSUR P0110), a new member of the Peptoniphilus genus. Strain KHD4 was isolated from the vaginal flora of a 33-year-old woman with bacterial vaginosis.

Streptococcus pneumoniae is a primary cause of bacterial infection in humans. Here, we present the complete genome sequence of S. pneumoniae strain A026, which is a multidrug-resistant strain isolated from cerebrospinal fluid.

Escherichia coli strain BL21 is one of the widely used bacterial hosts for high-level recombinant protein production and for other applications. Here, we present the complete genome sequence of a commercial version of the Escherichia coli BL21 strain.

background: acute bacterial meningitis is among serious infections of the central nervous system (cns). the early diagnosis and empiric antibiotic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16s rdna fragment following the pcr by universal primers led up fast and sensitive determination. the aims of the present study was to improve our...

Recurrent outbreaks of a disease in pond-cultured juvenile and subadult Litopenaeus vannamei shrimp in several districts in China remain an important problem in recent years. The disease was characterized by "white tail" and generally accompanied by mass mortalities. Based on data from the microscopical analyses, PCR detection and 16S rRNA sequencing, a new Vibrio harveyi strain (designated as ...

Insect infection models have been used increasingly to study various pathogenic agents in evaluations of pathogenicity and drug efficacy. In this study, we demonstrated that larvae of the silkworm Bombyx mori are useful for studying Listeria monocytogenes infections in insects. Infection with the L. monocytogenes wild-type strain induced silkworm death. Infection by a listeriolysin O (LLO) dele...

Streptococcus is the dominant bacterial genus in the human oral cavity and a leading cause of infective endocarditis. Streptococcus sanguinis belongs to the mitis group of streptococci and produces hydrogen peroxide (H2O2) by the action of SpxB, a pyruvate oxidase. In this study, we investigated the involvement of SpxB in survival of S. sanguinis in human blood and whether bacterial H2O2 exhibi...

Bacterial colonization of epithelial surfaces and subsequent transmigration across the mucosal barrier are essential for the development of infection. We hypothesized that the methyl-accepting proteins (MCPs), known as chemoreceptors expressed on Escherichia coli (E. coli) bacterial surface, play an important role in mediating bacterial transmigration. We demonstrated a direct interaction betwe...
