These 3 Superbugs Pose The Greatest Risk To Human Health
The World Health Organization is issuing a warning about a group of deadly bacteria: Recently, the WHO released its first-ever list of “priority pathogens,” a list of antibiotic-resistant bacteria that the organization says pose the greatest threat to human health. The list is divided into three categories: critical-, high- and medium-priority. Three pathogens made it into the critical-priority group. These bacteria are resistant to multiple antibiotics and pose a high risk to people in hospitals and nursing homes, the WHO says. Multidrug-resistant bacteria, sometimes called “superbugs,” are a ...

Bodyguards in the gut have a chemical weapon
(Max Planck Institute for Chemical Ecology) Beneficial bacteria in the gut of moth larvae produce an antibiotic that kills competing bacteria which otherwise have detrimental effects on insect development. An international team of scientists under the direction of the Max Planck Institute for Chemical Ecology in Jena, Germany, were able to demonstrate for the first time that symbiotic Enterococcus mundtii bacteria secrete the antimicrobial peptide mundticin. It enters harmful germs in the gut of the African cotton leafworm and kills them. (Source: EurekAlert! - Biology)

NARMS (National Antimicrobial Resistance Monitoring System) Integrated Report: 2014
U.S. Food and Drug Administration. 11/18/2016 This 33-page report summarizes the major findings of the National Antimicrobial Resistance Monitoring System (NARMS) for calendar year 2014, including the most important resistance findings for Salmonella and Campylobacter, Escherichia coli (E. coli) and Enterococcus. Although overall resistance continues to remain low for most human infections, and there have been measurable improvements in resistance levels in some important areas, the report discusses a few findings of potential concern.

How gut microbes help chemotherapy drugs
(Cell Press) Two bacterial species that inhabit the human gut activate immune cells to boost the effectiveness of a commonly prescribed anticancer drug, researchers report Oct. 4 in Immunity. The study identifies a new role for Enterococcus hirae and Barnesiella intestinihominis in activating cancer-fighting T cell immune responses, thereby enhancing the effects of the chemotherapy drug cyclophosphamide. Moreover, this microbe-driven immune response predicted longer progression-free survival in advanced lung and ovarian cancer patients treated with chemo-immunotherapy. (Source: EurekAlert! - Cancer)

Study explains how an intestinal microbe protects against other, more dangerous bacteria
Working in animal models, scientists have found that an enzyme produced by one microbe can shield the gut against attack from other, more harmful bacteria. The findings could potentially inform the design of new probiotics for use against dangerous pathogens like those spreading hospital-acquired infections.

[Report] A secreted bacterial peptidoglycan hydrolase enhances tolerance to enteric pathogens
The intestinal microbiome modulates host susceptibility to enteric pathogens, but the specific protective factors and mechanisms of individual bacterial species are not fully characterized. We show that secreted antigen A (SagA) from Enterococcus faecium is sufficient to protect Caenorhabditis elegans against Salmonella pathogenesis by promoting pathogen tolerance. The NlpC/p60 peptidoglycan hydrolase activity of SagA is required and generates muramyl-peptide fragments that are sufficient to protect C. elegans against Salmonella pathogenesis in a tol-1–dependent manner. SagA can also be heterologously expressed and s...

What Causes Hyperphosphatemia?
Discussion Constipation is a common problem in general pediatrics and its causes are numerous. It can cause acute and recurrent abdominal pain and is a cause of abdominal distention. Patients who are young, whose presentations are other than routine or who had complications should be invested for underlying causes of their constipation. This patient had undergone some evaluations in the past for constipation but because of the presentation of sepsis a more rigorous evaluation was undertaken. The differential diagnoses of the following can be found here: constipation, acute abdominal pain, recurrent abdominal pain, and abdo...

The Centers for Disease Control and Prevention (CDC) Says Hospitals Making Progress Against Antibiotic-Resistant Superbugs But More Work Is Needed
Adapted from MedlinePlus (Health Day) Health officials report that U.S. hospitals are making huge strides in the fight against antibiotic-resistance superbugs nevertheless, far too many people are becoming infected in health care facilities. The U.S. Centers for Disease Control and Prevention is advocating doctors, nurses and other health professionals to lead the fight against infections. Study senior author Dr. Clifford McDonald states, “It is reported that more than 700,000 patients in the United States are infected by bacteria and 75, 000 die from acquired infections.” He also adds, “In some hospital...

Wayne State receives $1.9 million NIH award to aid in treatment of life-threatening infections
(Wayne State University - Office of the Vice President for Research) Infections caused by vancomycin-resistant Enterococcus faecium (VREfm) bacteria can often be serious and life threatening. These drug-resistant bacterial pathogens are one of the most problematic in the hospital setting, especially in immune system deficient patients, and constitute an emerging local and global health crisis. Wayne State University recently received a five-year, $1.9 million grant from the the National Institutes of Health to further explore treatment of these problematic bacteria in the hospital setting.

Quorum Sensing in Gram-Positive Bacteria: Assay Protocols for Staphylococcal agr and Enterococcal fsr Systems
A thiolactone/lactone peptide-mediated quorum sensing (QS) system is commonly employed in gram-positive bacteria to control the expression of a variety of phenotypes, including the production of virulence factors and biofilm formation. Here, we describe assay protocols for the well-studied QS systems (agr and fsr) of two representative gram-positive pathogens, Staphylococcus aureus and Enterococcus faecalis. These convenient assay systems are useful for the screening of QS inhibitors as well as for basic research to address the mechanism of these QS systems.

Probiotics reduce piglet pathogens
(American Society for Microbiology) Piglets fed probiotic Enterococcus faecium showed reduced numbers of potentially pathogenic Escherichia coli strains in their intestines, according to a team of German researchers. The research is important, because in 2006 the European Union prohibited the feeding of antibiotics to livestock as growth promoters. Therefore, the research team sought to investigate whether probiotics could substitute for antibiotics, by reducing pathogen populations in the intestines. The study was published ahead of print in the journal Applied and Environmental Microbiology. (Source: EurekAlert! - Medicine and Health)

Researchers have found that wearing gloves and gowns in intensive care units does not reduce overall rates of acquiring MRSA or VRE, a study published online by JAMA has revealed. Bacteria methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) are the primary causes of health care-associated infections. And these, as the study notes, are the most common complication of hospital care, affecting an estimated 5% of inpatients. The study also records that the cost of antibiotic-resistance in the US is estimated at more than $4 billion per year... (Source: Health News from Medical News Today)

Researchers are defeating persistent bacteria known for causing infections in hospitals
The bacteria, Enterococcus faecalis, are the second-leading cause of hospital-associated infections in the U.S., said Lynn Hancock, associate professor of biology and leader of the research. His team has discovered how a regulatory system helps this bacteria resist a host's innate immune defense - a finding that may help develop novel drug compounds to fight the bacteria. "Right now, we have very limited therapeutic interventions because the bacteria is highly resistant to not only antibiotics but a variety of other environmental stresses," Hancock said...
