Caltech researchers measure the rate of DNA transfer from viruses to bacteria Researchers at the California Institute of Technology (Caltech) have been able, for the first time, to watch viruses infecting individual bacteria by transferring their DNA, and to measure the rate at which that transfer occurs. Shedding light on the early stages of infection by this type of virus–a bacteriophage–the scientists have determined that it is the cells targeted for infection, rather than...

A 150-foot-high garbage dump in Colombia, South America, may have new life as a public park. Researchers at the University of Illinois have demonstrated that bacteria found in the dump can be used to neutralize the contaminants in the soil. Jerry Sims, a U of I associate professor of crop sciences and USDA-Agricultural Research Service research leader and Andres Gomez, a graduate student from Medellín, Colombia, have been working on a landfill called “El Morro” in...

Mice carrying a set of friendly microbes that are usually found in humans fail to develop a proper immune system and are left susceptible to illness as a result. The findings in the June 22nd issue of the journal Cell, a Cell Press publication, show that animals have coevolved with and rely on their own very special array of microbial partners. As far as our immune systems are concerned, not just any bug collection will do. "Human microbe-colonized mice have gut immune systems that look...

Gross! Scientists Find More Than 10,000 Species Of Germs On The Human Body

Lawrence LeBlond for redOrbit.com Take a much closer look at the human body and you might see something you perhaps didn´t expect to find: a community of more than 10,000 different species of germs and bacteria, making their home on our skin, in our mouths, up our noses, and in our gut. While you may squirm at the thought of having so many germs crawling in, on, over and around your body, scientists are quick to point out that not all these germs are bad. In fact, researchers have...

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...

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...
