IL-10 production during intracellular bacterial infections is generally thought to be detrimental because of its role in suppressing protective T-helper cell 1 (Th1) responses. Francisella tularensis is a facultative intracellular bacterium that activates both Th1 and Th17 protective immune responses. Herein, we report that IL-10-deficient mice (Il10(-/-)), despite having increased Th1 and Th17...

Till date, only one draft genome has been reported within the genus Mangrovibacter. Here, we report the second draft genome shotgun sequence of a Mangrovibacter sp. strain MP23 that was isolated from the roots of Phargmites karka (P. karka), an invasive weed growing in the Chilika Lagoon, Odisha, India. Strain MP23 is a facultative anaerobic, nitrogen-fixing endophytic bacteria that grows optim...

Symbiotic interactions between insects and bacteria are ubiquitous and form a continuum from loose facultative symbiosis to greatly intimate and stable obligate symbiosis. In blood-sucking insects living exclusively on vertebrate blood, obligate endosymbionts are essential for hosts and hypothesized to supplement B-vitamins and cofactors missing from their blood diet. The role and distribution ...

Background:Pseudomonas aeruginosa is a gram negative non facultative bacterium and one of the members of normal flora in different sites of body in healthy humans.this bacterium can resist in fluids and hospital environments for a long time.Pseudomonas aeruginosa has two systems for glucose uptake:a low affinity oxidative pathway and a high affinity phosohorylative pathway.Although the role of ...

A facultative anaerobic bacterium, designated as strain SCS5, was isolated from the anodic biofilm of a mediator-less microbial fuel cell using acetate as the electron donor and α-FeOOH as the electron acceptor. The isolate was Gram-negative, motile, and shaped as short rods (0.9-1.3 μm in length and 0.4-0.5 μm in width). A phylogenetic analysis of the 16S rRNA, gyrB, and rpoD genes suggested t...

A novel Gram-negative and facultative anaerobic strain, designated MS1T, was isolated from gajami sikhae, a traditional fermented food in Korea made from flatfish. Strain MS1T was motile, rod-shaped and oxidase- and catalase-positive, and required 1-2% (w/v) NaCl for growth. Growth occurred at temperatures ranging from 4 to 40 degrees C and the pH range for optimal growth was pH 6.5-9.0. Strain...

The Montreal Biodome operates a methanol-fed denitrification system that treats the water in its three million litre marine mesocosm. An unknown bacterium, named strain NL21T, was isolated from this system on TSA and R2A agar. The organism is a Gram-negative, rod-shaped (1x3 microm) facultative aerobe. Optimal growth conditions on R2A agar are 30-35 degrees C, pH 7-7.5 and 1% (w/w) NaCl. Phylog...
