Engineered Bacteria can be used as Vaccines

Researchers at the Imperial College London have engineered Salmonella bacteria to use it for vaccination. Normally, Salmonella bacteria possess nanoscopic needles through which it injects its own protein into host cells. These proteins assist them to replicate and survive into those host cells.

Engineered Bacteria for Efficient Vaccines

Research recently done on genetically engineered strains of bacteria at University of Texas has shown promise to come up with vaccines with improved efficacy. These strains serve as biological adjuvants, which can be more effective in eliciting human immune response. Read more…

A Novel “Persister” Phenotype of Vibrio Cholerae

Cholera continues to be a major public health threat, particularly in countries where safe drinking water, sanitation and hygiene are suboptimal. Toxigenic Vibrio cholerae, responsible for epidemic cholera, has two life styles, including (i) a transient and accidental occurrence Read more…

Hydrogen-Stimulated Carbon Catabolism in Enteric Pathogens

H2-oxidizing nickel-containing hydrogenases allow enteric and other pathogens to use H2 within host tissues, and aids pathogens survival within macrophages.Among the genes up-expressed by exposure of Salmonella entericaserovartyphimurium to H2—a byproduct of intestinal commensal metabolism, Read more…

Role of HipA and HipB in Bacterial Multidrug Tolerance

During exponential growth of Escherichia coli, one cell per ~1,000,000 becomes dormant. Dormancycan lead to multidrug tolerance, as many antibiotics work by attacking the machinery associated with cell wall biosynthesis, DNA replication or translation Read more…
