Bacteria A Benefit Cell

Prediction of T-cell epitopes for designing a reverse vaccine against streptococcal bacteria

Streptococcal bacteria are among dangerous human pathogens with major prevalence worldwide. A good vaccine against streptococcal bacteria should have epitopes that confer protection from infection by different streptococcal bacteria types. we aimed was to recognize the most immunogenic and conserved epitopes of streptococcal bacteria, which could be a potential candidate for vaccine development...

Sulfurous Analysis of Bioelectricity Generation from Sulfate-reducing Bacteria (SRB) in a Microbial Fuel Cell

The current importance of energy emphasizes the use of renewable resources (such as wastewater) for electricity generation by microbial fuel cell (MFC). In the present study, the native sulfate-reducing bacterial strain (R.gh 3) was employed simultaneously for sulfurous component removal and bioelectricity generation. In order to enhance the electrical conductivity and provision of a compatible...

Cell-bound Exopolysaccharide Extract from Indigenous Probiotic Bacteria Induce Apoptosis in HT–29 cell-line

Background and Objective: The aim of this study was to compare the cytotoxic effects of local probiotic bacteria, including Lactobacillus paracasei, Lactobacillus brevis, while isolated from “Tarkhine” food and the induction of apoptosis in the HT–29 human colon adenocarcinoma cell line and normal fibroblasts. Methods: HT–29 and L–929 cell lines were trea...

Cell Envelope Structure and Functions in Gram-negative Bacteria

Flagellated ectosymbiotic bacteria propel a eucaryotic cell

A devescovinid flagellate from termites exhibits rapid gliding movements only when in close contact with other cells or with a substrate. Locomotion is powered not by the cell's own flagella nor by its remarkable rotary axostyle, but by the flagella of thousands of rod bacteria which live on its surface. That the ectosymbiotic bacteria actually propel the protozoan was shown by the following: (...
