Researchers at Michigan State University (MSU) have demonstrated how a new virus evolves, shedding light on how easy it can be for diseases to gain dangerous mutations.
Using a combination of evolutionary biology and virology, scientists at Fred Hutchinson Cancer Research Center have traced the birth of the ability of some HIV-related viruses to defeat a newly discovered cellular-defense system in primates.
New research at Harvard explains how bacterial biofilms expand to form slimy mats on teeth, pipes, surgical instruments, and crops.
Even the tiniest microscopic organisms make waves when they swim.
A short burst of low voltage alternating current can effectively eradicate E. coli bacteria growing on the surface of even heavily contaminated beef.
For the first time, researchers have analyzed the multitude of microorganisms residing in the human gut as a complex, integrated biological system, rather than a set of separate species.
Researchers at Duke University Medical Center have developed a new way to identify the genes of harmful microbes, particularly those that have been difficult to study in the laboratory.
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 Î±-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...
