Loss of a universal tRNA feature

Scientists at the Virginia Bioinformatics Institute (VBI) report in the Journal of Bacteriology that two alphaproteobacteria lack the universal extra guanylate nucleotide typically found in the transfer RNA molecule tRNAHis.

The skin is alive ... with a zoo of bugs!

According to a new study, the largest organ in our body, the skin, is home to a virtual zoo of bacteria some of which are have never been seen before.

Peptide vaccine fights off breast tumors with help of bacteria-mimicking agents

With the help of immune system-stimulating molecules that mimic bacterial components, researchers have used a type of cancer vaccine to both delay and prevent breast tumors in mice.

Different treatments may be needed for chronic asthma, depending on whether it results from allergies or lung infections

Researchers have now identified a particular gene that influences how severe a M. pneumoniae infection may be, which in turn suggests that a different strategy might be needed for treating asthma resulting from this and similar lung infections rather than allergies.

Salmonella survives better due to altered DNA

Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food.

New understanding of cholera pathogen

Researchers at Rensselaer Polytechnic Institute have discovered new details about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera.

Antibiotic doses could be reduced by up to 50 times using new approach

Steven Hagens, previously at the University of Vienna, told Chemistry & Industry, the magazine of the SCI, that certain bacteriophages, a type of virus that infects bacteria, can boost the effectiveness of antibiotics gentamicin, gramacidin or tetracycline.

A plasminogen-activating protease specifically controls the development of primary pneumonic plague

The deadly attack of the bacterium that causes pneumonic plague is significantly slowed when it can't make use of a key protein, scientists at Washington University School of Medicine in St. Louis report in Science.

Yaws disease re-emerging

Yaws, a disease which eats away at the skin, cartilage and bones of its victims (mostly children), is re- emerging in poor, rural and marginalized populations of Africa, Asia and South America.

Minor mistake in protein production at the cellular level may lead to serious neurological diseases

But exactly how the cell avoids such mistakes has remained unclear until now. Researchers at Ohio State University found the mechanism that prevents such errors, and explain their findings in the Proceedings of the National Academy of Sciences.

New understanding of the hit-and-run tactics used by infectious bacteria

New research from scientists at the University of Cambridge has the potential to radically change our understanding of how infection spreads around the body and improve the methods used to control it.

Sequella receives FDA fast track status for pulmonary tuberculosis drug

Sequella, Inc. has announced it has received Fast Track designation from the U.S. Food and Drug Administration (FDA) for SQ109, the company's proprietary lead drug candidate for treatment of pulmonary tuberculosis (TB).

Lung neutrophils produce histamine in significant quantities

In a surprise finding, scientists have discovered that histamine, the inflammatory compound released during allergic reactions that causes runny nose, watery eyes, and wheezing, can be produced in large amounts in the lung by neutrophils, the white blood cells that are the major component of pus.

New treatment technique for decontaminating flood water

Engineers have developed a system that uses a simple water purification technique that can eliminate 100 percent of the microbes in New Orleans water samples left from Hurricane Katrina. The technique makes use of specialized resins, copper and hydrogen peroxide to purify tainted water.

Study shows why the body's immune system doesn't attack tissues in the small intestine

Answering one of the oldest questions in human physiology, researchers at Dana-Farber Cancer Institute have discovered why the body's immune system - perpetually on guard against foreign microbes like bacteria - doesn't attack tissues in the small intestine that harbor millions of bacteria cells.

Modified skin cells that may help protect cultured skin substitutes from infection

Cincinnati burn researchers have created genetically modified skin cells that, when added to cultured skin substitutes, may help fight off potentially lethal infections in patients with severe burns.

Allergic reactions to insulin have declined and Continuous Subcutaneous Insulin Infusion could reduce them further

A review of published research from the University of Liege, Belgium, reveals a decline in the number of people experiencing allergic reactions to insulin. This is largely due to better purification of animal insulin and the introduction of human recombinant insulin.
