National Institutes of Health (NIH) scientists and their colleagues in China have described a rapidly emerging Staphylococcus aureus gene, called sasX, which plays a pivotal role in establishing methicillin-resistant S. aureus (MRSA) epidemics in most of Asia. Senior author Michael Otto, Ph.D., of NIH's National Institute of Allergy and Infectious Diseases, says these findings illustrate at the molecular level how MRSA epidemics may emerge and spread. Moreover, their study identifies a...

Transmission of MRSA between mothers and newborns examined The need to swab the noses of pregnant women and newborns for the presence of MRSA (methicillin-resistant Staphylococcus aureus) may be unfounded, according to a Vanderbilt study now available online and published in the May issue of Pediatrics. The study's senior author, Buddy Creech, M.D., MPH, assistant professor of Pediatrics, said it is often feared that mothers carrying MRSA may risk transmitting an infection to their...

New data presented at the International Liver Congress 2012 shows consolidation of the interferon-free (IFN) revolution in HCV treatment. The much anticipated data from a number of clinical trials confirm that combinations of antivirals offer the hope of shorter, more effective treatment with fewer side effects. The following new studies cover the treatment of HCV patients with genotypes (GT) 1, 2 or 3, who were administered ribavirin (RBV) - without IFN - and either one or two other...

UCSB Researchers Discover Particularly Dangerous Salmonella
2012-04-18 10:36:25

UC Santa Barbara researchers have discovered Salmonella bacteria that are up to 100 times more capable of causing disease. Their findings may help prevent food poisoning outbreaks that continue to plague public health and the food industry. These "hypervirulent" bugs can override vaccines and pose a risk to food safety —— and mitigation efforts are currently under way. Previous strategies to find the more dangerous bugs were unsuccessful since they behave like a "Trojan...

Disruption of key cellular functions produces physiologic and behavioral responses Two Massachusetts General Hospital (MGH)-based research teams, along with a group from the University of California at San Diego, have discovered that animals have a previously unknown system for detecting and responding to pathogens and toxins. In three papers published in the journals Cell and Cell Host & Microbe, the investigators describe finding evidence that disruptions to the core functions of...

Bacteria such as Staphylococcus aureus, the ℠superbug´ behind MRSA, can be a major problem for patients who have a medical implant, such as a replacement heart valve or pacemaker. Bacteria are able to form colonies -- called biofilms -- on the implanted device, which can lead to wider infections such as endocarditis, a bacterial infection of the heart. Research led by scientists in the Department of Biology at the University of York has shed new light on how these...

New treatments that combat the growing problem of antibiotic resistance by disarming rather than killing bacteria may be on the horizon, according to a new study. Published in Nature Structure and Molecular Biology, research led by Monash University showed a protein complex called the Translocation and Assembly Module (TAM), formed a type of molecular pump in bacteria. The TAM allows bacteria to shuttle key disease-causing molecules from inside the bacterial cell where they are made, to...

Drug dispensing robots designed to quickly prepare intravenous medications in a sterile environment can harbor dangerous bacteria, according to a report in Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. During a routine screening in 2010, personnel at Wake Forest Baptist Medical Center in North Carolina discovered Bacillus cereus bacteria in samples dispensed by their machine, the Intellifill IV. "To our knowledge, this is...

Streptococcus salivarius is a species of spherical, Gram-positive bacteria which colonize the mouth and upper respiratory tract of humans a few hours after birth, making further exposure to the bacteria harmless. The bacterium is an opportunistic pathogen which rarely makes its way into the bloodstream where it is associated with septicemia cases in people with neutropenia. It has different characteristics when exposed to different environmental nutrients. In the lab a SYTA plate is used...

Streptococcus oralis is a Gram positive bacterium that grows characteristically in chains. On a Wilkins-Chalgren agar plate it will form slam white colonies. It is classified as a member of the streptococcus mitis group and is found in high numbers in the oral cavity. S. oralis produce neuraminidase and an IgA protease and cannot bind α-amylase.

Enterococcus is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals. It is a main constituent of some probiotic food supplements. E. faecalis can cause life-threatening infections in humans, especially in the nosocomial environment, where the naturally high levels of antibiotic resistance found in E. faecalis contribute to its pathogenicity. It is frequently found in root canal-treated teeth in prevalence values ranging from 30% to 90% of...

Staphylococcus epidermidis is one of thirty-three known species belonging to the genus Staphylococcus. It is part of our skin flora and can also be found in the mucous membranes and in animals. It is the most common species found in laboratory test due to contamination. It is not usually pathogenic; however, patients with a compromised immune system often risk infection. Infections can be both nosocomial and community acquired and are more of a threat to hospital patients. Hospitals carry...

Serratia marcescens is a species of Gram-negative, rod-shaped bacterium in the family Enterobacteriaceae. S. marcescens is involved in nosocomial infections particularly catheter-associated bacteremia. It is commonly found in respiratory and urinarty tracts of hospitalized adults and often in the gastrointestinal system of children. It is commonly found growing in bathrooms due to its preference for damp conditions. It manifests as a pink discoloration and a slimy film feeding off...
