The findings, published this week in mBio, an online open-access journal of the American Society for Microbiolo... Read More

Killing Dormant HIV with Cancer Drug

BOC Sciences-Recently Scientists found a new way to kill the hiding and dormant Human Immunodeficiency Virus( HIV) by employing a type of cancer drug, which is proved very effective but still waiting for further trial and approval by the US FDA. Read More

The bacteria-fighting super element that’s making a comeback in hospitals: copper

Ancient Egyptians used copper to sterilize chest wounds and drinking water. Greeks, Romans and Aztecs relied on copper compounds to treat burns, headaches and ear infections. Thousands of years later, the ancient therapeutic is being embraced by some hospitals because of its ability to kill bact... Read More

Humans differ in their personal microbial cloud

Dispersal of microbes between humans and the built environment can occur through direct contact with surfaces or through airborne release; the latter mechanism remains poorly understood. Humans emit upwards of 106 biological particles per hour, and have long been known to transmit path... Read More

Sexual transmission of Ebola virus in Liberia confirmed using genomic analysis

A suspected case of sexual transmission of Ebola virus disease (EVD) in Liberia was confirmed using genomic analysis, thanks to in-country laboratory capabilities established by U.S. Army scientists in collaboration with the Liberian Institute for Biomedical Research (LIBR). Read More

Flu remedies help combat E. coli bacteria

Trillions of bacteria populate the human gut - which makes them more common than any other cells in our body. The composition of this bacterial population is very variable and influenced by our diet. Diseases, but also antibiotic treatments can induce significant shifts in this equilibrium. If e... Read More

Genetic differences may help explain inconsistent effectiveness of anti-HIV drug

Research with human tissue and cells suggests that genetic variations, in addition to failure to comply with treatment regimens, may account for some failures of an anti-HIV drug to treat and prevent HIV infection. Read More

High rate of Texas bugs carrying Chagas disease

A deadly parasite that causes Chagas disease is widespread in a common Texas insect, according to a new study by University of Texas at El Paso (UTEP) researchers. The finding suggests that the risk of Texans contracting the disease may be higher than previously thought. Read More

In very ill, probiotics don't prevent 'superbugs' from colonizing intestinal tract

Compared with routine medical care, probiotics administered to critically ill patients in intensive care units showed no benefit in preventing the colonization of drug-resistant microbes in the intestinal tract, according to new research at Washington University School of Medicine in St. Louis.

Wasps do a gain-of-function experiment in caterpillars

Parasitic wasps inject their eggs into lepidopteran hosts, where they carry out their developmental stages. Along with the eggs, the wasps also deliver viruses carrying genes encoding proteins which inhibit caterpillar immune defenses. Some of these genes are permanently transferred to the lepid...

Towards an HIV vaccine

Neutralizing antibodies (Nabs) are immune proteins that recognize, bind to, and trigger the elimination of virus before it can establish a chronic infection. How to elicit a potent Nab response capable of protecting against different HIV subtypes and against different modes of infection is criti... Read More

B cell depletion benefits ME/CFS patients

Patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) showed clinical improvement after extended treatment with the anti-B-cell monoclonal antibody rituximab. This result suggests that in a subset of patients, ME/CFS might be an autoimmune disease. Read More
