Urinary Metabolites of Green Tea as Potential Markers of Colonization Resistance to Pathogenic Gut Bacteria in Mice.

Background: The gut microbiome (GMB) generates numerous chemicals that are absorbed systemically and excreted in urine. Antibiotics can disrupt the GMB ecosystem and weaken its resistance to colonization by enteric pathogens such as . If the changes in GMB composition and metabolism are sufficiently large, they can be reflected in the urinary metabo-lome.

Preliminary analysis of the antimicrobial activity of a postoperative wound dressing containing chlorhexidine gluconate against methicillin-resistant Staphylococcus aureus in an in vivo porcine incisional wound model.

Background: Surgical site infection is a major postoperative complication after surgical procedures. The effectiveness of postoperative antimicrobial dressings in reducing surgical site infections is unclear and limited information is available on the efficacy of chlorhexidine gluconate (CHG)-impregnated postoperative dressings.

Methods: A pilot study was conducted to examine the efficacy of an innovative CHG-impregnated postoperative dressing in reducing the burden of methicillin-resistant Staphylococcus aureus (MRSA) in an in vivo porcine, incisional-wound model.

The Transformative Possibilities of the Microbiota and Mycobiota for Health, Disease, Aging, and Technological Innovation.

The gut microbiota is extremely important for the health of the host across its lifespan.Recent studies have elucidated connections between the gut microbiota and neurological diseaseand disorders such as depression, anxiety, Alzheimer's disease (AD), autism, and a host of otherbrain illnesses. Dysbiosis of the normal gut flora can have negative consequences for humans,especially throughout key periods during our lifespan as the gut microbes change with age in bothphenotype and number of bacterial species.

Dispersal of gram-negative bacilli from contaminated sink drains to cover gowns and hands during hand washing.

We demonstrated that hand washing resulted in frequent dispersal of gram-negative bacilli from colonized sink drains in hospitals to cover gowns and hands. A plastic drain cover reduced but did not eliminate the risk for contamination. This mechanism of dispersal could result in contamination of healthcare personnel and patients.

Contamination of Health Care Personnel During Removal of Personal Protective Equipment.

Importance: Contamination of the skin and clothing of health care personnel during removal of personal protective equipment (PPE) contributes to dissemination of pathogens and places personnel at risk for infection.

Objectives: To determine the frequency and sites of contamination on the skin and clothing of personnel during PPE removal and to evaluate the effect of an intervention on the frequency of contamination.

Design, Setting, And Participants: We conducted a point-prevalence study and quasi-experimental intervention from October 28, 2014, through March 31, 2015.
