Vaccine to prevent Campylobacter in chickens can help reduce food-borne illness

A vaccine could be developed to prevent Campylobacter being carried in chickens.

Gene fault linked to flu risk for hospitalization: Study finds

Researchers have found a genetic flaw that may explain why some people get more ill with flu than others. The study was reported in the journal Nature this Sunday, where researchers said the variant of the IFITM3 gene was much more common in people hospitalized for flu than in the general population. It controls a malformed protein, which makes cells more susceptible to viral infection. Experts said those with the flaw could be given the flu jab, like other at-risk groups.

Also, certain groups of young women are more likely to do so than others. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study indicates that efforts are needed to provide counseling on fertility preservation in reproductive-aged women diagnosed with cancer.

Extreme norovirus flexibility may allow for broad antibody recognition

Twenty million Americans get sick from norovirus each year according to data released last week by the Centers for Disease Control (CDC). Often called vomiting illness, it can spread rapidly on cruise ships, and in dormitories and hospitals. Recent data from the CDC shows deaths from gastrointestinal infections have more than doubled and have become a particular threat to the elderly.

GUCY2C gene mutation leads to familial diarrhea syndrome

When the intestines are not able to properly process our diet, a variety of disorders can develop, with chronic diarrhea as a common symptom. Chronic diarrhea can also be inherited, most commonly through conditions with genetic components such as irritable bowel syndrome. Researchers in Norway, India, and at the HudsonAlpha Institute for Biotechnology have identified one heritable DNA mutation that leads to chronic diarrhea and bowel inflammation.

Study identifies new hypervariable regions in human gut viruses

A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. Frederic D. Bushman, PhD, professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania, led a study published this month in the Proceedings of the National Academy of Sciences that sequenced the DNA of viruses -- the virome -- present in the gut of healthy people.

New information on efficacy of CLA in treating Crohn's disease

The Nutritional Immunology and Molecular Medicine Laboratory (NIMML) research team at Virginia Tech has discovered important new information on the efficacy of conjugated linoleic acid (CLA) in treating Crohn's disease, a form of inflammatory bowel disease (IBD). CLA is a naturally occurring acid found in meat and dairy products known for its anti-cancer and immune modulatory properties.

Disruptions in immune system regulation may play a role in NEC

Despite advances in neonatal care, necrotizing enterocolitis (NEC) - the most common gastrointestinal emergency in premature infants - continues to be a deadly disease. "We haven't made a lot of progress in identifying babies early who may be at risk for NEC, preventing it or treating it," said J-rn-Hendrik Weitkamp, M.D., a neonatologist and assistant professor of Pediatrics at Monroe Carell Jr. Children's Hospital at Vanderbilt.
