The resulting efflux of metabolites and cell contents and dissipation of ion gradients causes bacterial cell death. [19] However, bacteriocins can also induce death by translocating into the periplasmic space and cleaving DNA non-specifically (colicin E2), inactivating the ribosome (colicin E3), inhibiting synthesis of peptidoglycan , a major ...
Studies have shown that bacterial degradation of amino acids can be significantly enhanced through the process of syntrophy. [30] Microbes growing poorly on amino acid substrates alanine , aspartate , serine , leucine , valine , and glycine can have their rate of growth dramatically increased by syntrophic H 2 scavengers.
Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce.Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics.
A new study proposes that endometriosis could be diagnosed using a non-invasive stool sample to measure levels of a bacterial metabolite — 4-hydroxyindole — that is significantly lower in ...
Scheme of the complement system. The complement system, also known as complement cascade, is a part of the humoral, innate immune system and enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.

Since the MR1 molecule is involved in presentation of cancer specific antigens and plays a role in tumor immunosurveillance, it has potential use in immunotherapy. [21] Specific clones of MR1 T lymphocytes (MC.7.G5) were able to kill various cancer cells in vivo and in vitro and were inert to noncancerous cells.
WORCESTER, Mass. – Local police in this central Massachusetts city used excessive force and engaged in “outrageous” sexual contact with women during undercover operations, a two-year civil ...
Venn diagram showing pharmacomicrobiomics as a sub-field of genomics, microbiology, and pharmacology. Pharmacomicrobiomics, proposed by Prof. Marco Candela for the ERC-2009-StG project call (proposal n. 242860, titled "PharmacoMICROBIOMICS, study of the microbiome determinants of the different drug responses between individuals"), and publicly coined for the first time in 2010 by Rizkallah et ...
