Recent discovery about C. difficile could pave the way for new treatments

Researchers have found that sporulation, which helps the bacterium C. difficile survive and spread, is regulated by epigenetics.

New flu drug makes influenza viruses develop resistance

Researchers have discovered a mutation in strains of influenza treated with a drug that makes the virus resistant to treatment.

Discovery enables strategies to be developed for preventing malaria transmission

The bacteria that form the gut microbiota influence important processes of the human body, such as digestion, nutrient absorption, and defense against pathogens. The same type of relationship is present in most animals, including in the Anhopheles darlingi mosquito, the main vector of malaria in Brazil.

Immunity within the lung tissue provides most protection for preventing pneumonia

Previous research has shown that recovery from bacterial pneumonia hugely improves our defense against further infections by seeding the lungs with immune cells called lung resident memory T (TRM) cells, but how these cells actually protect the lungs against future bacterial infections has been unknown until now.

Researchers develop breakthrough in marine sponge cell culture

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates.

Experimental vaccine elicits antibodies that can neutralize multiple HIV strains

An experimental HIV vaccine developed by scientists at Scripps Research and the nonprofit vaccine research organization IAVI has reached an important milestone by eliciting antibodies that can neutralize a wide variety of HIV strains.

Exploring the links between chronic stress, inflammation and depression

Chronic stress can inflame our brain, destroy the connections between our neurons and result in depression, scientists say.

UC Davis study identifies mechanism to rapidly repair leaky gut in monkeys with SIV infections

A UC Davis study found that the damaged gut lining (known as leaky gut) in monkeys infected with chronic simian immunodeficiency virus (SIV), an HIV-like virus, was rapidly repaired within five hours of receiving Lactobacillus plantarum bacteria.

'Dysbiosis' promotes the onset of colorectal cancer

The gastroenterology team at Henri-Mondor AP-HP Hospital and University Paris-Est Créteil, led by Professor Iradj Sobhani, together with teams from Inserm and the Institut Pasteur Molecular Microbial Pathogenesis Unit (U1202), led by Professor Philippe Sansonetti - holder of the Microbiology and Infectious Diseases Chair at the Collège de France -, have demonstrated that an imbalance in the gut microbiota, also known as "dysbiosis", promotes the onset of colorectal cancer.

New clinical guideline for treatment of drug-resistant tuberculosis published

The American Thoracic Society, Centers for Disease Control and Prevention, European Respiratory Society and the Infectious Diseases Society of America have published an official clinical guideline on the treatment of drug-resistant tuberculosis in the Nov. 15 American Journal of Respiratory and Critical Care Medicine.

CSU awarded $1.2 million subcontract to accelerate tuberculosis vaccine development

A team of researchers in the Department of Microbiology, Immunology and Pathology at Colorado State University aim to advance what is known about the complex immune response necessary to prevent tuberculosis disease.

Study provides new insights into potential outcomes of Zika virus infection

Using a relevant animal model (pigs), University of Saskatchewan researchers have shown that mild Zika virus infection in fetuses can cause abnormal brain development in apparently healthy young animals.

Study shows potential of phage therapy to treat alcoholic liver disease

Bacteriophages (phages) are viruses that specifically destroy bacteria. In the early 20th century, researchers experimented with phages as a potential method for treating bacterial infections.

Tulane virus needs intracellular calcium to replicate

Some gastrointestinal viruses need calcium. They need calcium ions to carry out several essential aspects of viral life, such as entry into host cells, genome replication and building new viruses to invade other cells. The cells invaded by viruses also use calcium. They use it as signals to regulate many of the cells' own processes, but viruses can takeover cellular calcium signaling to satisfy their own needs.

Fertilization discovery reveals egg's role, potentially paves way for new contraceptive

An unexpected discovery about fertilization from the University of Virginia School of Medicine reveals new insights on how sperm and egg fuse and could have major implications for couples battling infertility – and may lead to a future male contraceptive.
