11/18/13 Health News: Home Test for Strep, Listeria Develops Disinfectant Resistance, New Protein May Be Key Cancer. Microbes on Skin

Home Test for Pharyngitis (Sore Throat) May Reduce Unneeded Strep Cultures
A patient-driven approach to streptococcal pharyngitis diagnosis using a new home test score might save on unnecessary physician visits, cultures, and treatment, according to a retrospective cohort study published online November 4 in the Annals of Internal Medicine. continue reading

Immune System Shapes Skin Microbiome
The human body contains many microbes, some of which are necessary for healthy bodily functions including digestion. Others, such as some microbes living on our skin, may be pathogenic. Previous studies investigated how these microbes educate and shape the human immune system. There is little known, however, if the immune system influences the types of microbes that live on the skin and thus potentially prevents disease. "In addition to questions about how microbes affect the human host, there is an interest in understanding how the human host affects the microbes that make our skin their home," says Heidi Kong of the National Cancer Institute and co-senior author of the study. "Our findings suggest that the human body, including our immune systems, constraints and potentially selects which bacteria and fungi can inhabit skin," says Kong Continue reading

Listeria’s Resistance to Disinfectants
Listeria poses a significant risk to human health. The bacterium is frequently transmitted via dairy products, so it is important to disinfect dairies regularly. Unfortunately, listeria is developing resistance to the most frequently used compounds. Continue Reading

Newly Identified Protein Could Be a Cancer Key

Scientists at the University of Dundee have identified a protein that could be key in the fight against cancer. Researchers in the College of Life Sciences at Dundee have demonstrated that cancer cells need a protein called Bod1 to grow and divide. When this protein is removed cancer cells lose control of cell division and die. Continue Reading
