The Bacterial Protein promoting Cancer

Viral Oncology :  The Bacterial Protein promoting Cancer DNA K, a protein of the bacterium mycoplasma, interferes with the mycoplasma-infected cell's ability to respond to and repair DNA damage, a known origin of cancer.  Little or no mycoplasma DnaK DNA sequences were found associated with the tumor, which was fully developed, suggesting a hit-and-run or hide mechanism of transformation, indicating that the damage is done early, but the protein may not be needed once the cancer cells are formed.                   Mycoplasmas are a family of bacteria that are associated with cancers, especially in people with HIV. Researchers utilized immune-compromised mice as a model for analyzing the effect of mycoplasma infection on the development of lymphoma. They compared how quickly non-infected immune-compromised mice developed lymphoma compared to mycoplasma-infected immune-compromised mice. The mice were infected with a strai...

Antimicrobial Resistance:Searching for clues to fight antibiotic resistance

To conflict the rise of drug-resistant bacteria , researchers are developing how one superbug bacteria adapts to fight with an antibiotic of last resort, hoping to find clues that can lengthen the drug's effectiveness. Researchers at Rice University and the University Of Texas Health Science Centre at Houston ran experiments to track the biochemical changes that vancomycin-resistant Enterococci (VRE) underwent as they adapted to fight another antibiotic, daptomycin. "We need to get to a platform where we can anticipate how these pathogens will become resistant to antibiotics so we can stay one step ahead of them," said Rice biochemist Youssef Shampoo, co-author of a study in the journal Antimicrobial Agents and Chemotherapy that found VRE can develop resistance to daptomycin in more than one way. The stakes are high. In 2014, the World Health Organization reported that antibiotic-resistant infections were on pace to kill 10 million people per year worl...

The secret life of Antimicrobial peptides

Image
              When it comes to the immune system, we usually think about lymphocytes B and T cells or macrophages going on constant seek-and-destroy missions against invading pathogens like bacteria and viruses. But our immune system actually includes a lesser-known and less-studied first line of defence referred to as "innate immunity ." One of the main weapons of innate immunity is a family of small peptides, collectively known as " antimicrobial peptides" or AMPs for short. AMPs are produced by the host's (e.g. the human's) cells and combat invading microorganisms by breaking apart their cell membranes or by disrupting their functions. Despite of their importance, we know very little about AMPs. Some in vitro studies have shown that they can kill bacteria and fungi, but scientists have been hard pressed to study them in living organisms. One of the reasons is that there are simply too many factors involved in innate immunity, so isol...

Antimicrobial congress 2019

                     ME Conferences invites all the participants from all over the world to attend ‘ ANTIMICROBIAL CONGRESS 2019 ’ which includes prompt Keynote Presentations, Special Sessions, Workshops, Symposiums, Oral talks, Poster Presentations, and Exhibitions. An antimicrobial is an operator who kills the microorganisms or suppresses their development. They are classified according to their mode of action on the particular microorganism. Depending upon the range of bacterial species helpless to these specialists antibacterial is classified as a wide range, intermediate-spectrum, or narrow- range. Non–pharmaceuticals antimicrobial gives a wide range of chemical and common compounds utilized as antimicrobials. The Immunology of have defence peptides gives assorted activities of HDPs. The utilize and misuse of antimicrobial drugs quickens the rise of drug-resistant strains. Post-antibiotic period alludes to a time...
