Family members of children with a staph infection often harbor a drug-resistant form of the germ, although they don't show symptoms, a team of researchers from Washington University School of Medicine in St. Louis has found. The investigators focused on family members of nearly 200 children who had Staphylococcus aureus infections in the skin and soft tissue, in areas such as the nose, armpits and/or groin. They found that of the more than 600 household members who lived with the children,...

Cell Analysis Possible Thanks To Biochip-based Device
2012-05-30 11:04:44

Inexpensive, portable devices that can rapidly screen cells for leukemia or HIV may soon be possible thanks to a chip that can produce three-dimensional focusing of a stream of cells, according to researchers. "HIV is diagnosed based on counting CD4 cells," said Tony Jun Huang, associate professor of engineering science and mechanics, Penn State. "Ninety percent of the diagnoses are done using flow cytometry." Huang and his colleagues designed a mass-producible device that can focus...

In today's Nature scientific journal Dr. Gregor Reid, Director of the Canadian R&D Centre for Probiotics at Lawson Health Research Institute and a scientist at Western University, calls for a Category Tree system to be implemented in the United States and Europe to better inform consumers about probiotics. Globally, the market for probiotics (beneficial microorganisms) exceeds $30 billion; however, consumers have little way of knowing which products have been tested in humans and what...

Methicillin-resistant Staphylococcus (MRSA) nasal colonization is associated with longer hospital stays and an increase in surgical site infections (SSI) in patients undergoing major gastrointestinal surgery, according to a new study from Scott and White Memorial Hospital, Temple, TX. Antibiotic-resistant organisms such as MRSA can cause infections after surgery. Many studies have shown that MRSA nasal colonization increases the risk of developing SSI, and there has been an effort to...

Whilst some bacteria can provide health benefits there are others that can do annoying things — like kill you. So in order to save ourselves we should probably kill them first. So, stand aside bacterial wipes, hand sanitizers and antiseptic sprays there is a new bug zapper in town. Bring in the plasma flashlight — a torch that emits a plasma jet that kills bacteria on the skin in an instant. Developed by a group of Chinese and Australian scientists, including CSIRO, the...

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...

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...
