The study, published today in the Open Access journal PLOS Pathogens, shows for the first time that a protein located on the bacterial surface called clumping factor B (ClfB) has high affinity for the skin protein loricrin. http://medicalxpress.com/news/2012-12-staphylococcus-aureus-nose.html Diseases, Conditions, Syndromes Thu, 27 Dec 2012 17:00:01 EST news275848959 Current hospital cleaning protocol may be inadequate to rid patient rooms of multidrug-resistant (MDR) Acinetobacter baumannii, according to a study in the December issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC). http://medicalxpress.com/news/2012-11-hospital-protocol-ineffective-baumannii.html Diseases, Conditions, Syndromes Fri, 30 Nov 2012 10:45:43 EST news273494730 (Medical Xpress)—Farmers regularly use low-dose antibiotics to fatten livestock for market.

A new study, published in BioMed Central's open access journal Genome Biology, shows that differences in bacterial colonization of formula-fed and breast-fed babies leads to changes in the infant's expression of genes involved in the immune system, and in defense against pathogens. http://medicalxpress.com/news/2012-04-breastfeeding-healthy-infant-gut.html Medical research Mon, 30 Apr 2012 03:10:01 EST news254971282 Researchers from Boston University School of Medicine (BUSM) have for the first time identified a novel pathway that is necessary for infection to occur with the pathogen Neisseria gonorrhoeae, which is responsible for the second most common infectious disease worldwide, gonorrhea. The study, which was recently published online in the Journal of Bacteriology, may lead to new treatment methods for this sexually transmitted disease. http://medicalxpress.com/news/2012-02-pathway-responsible-infection-common-std.html Diseases, Conditions, Syndromes Mon, 27 Feb 2012 14:51:46 EST news249576682
