Latest Clinical pathology Stories
A common oral bacteria, Fusobacterium nucleatum, acts like a key to open a door in human blood vessels and leads the way for it and other bacteria like Escherichia coli to invade the body through the blood and make people sick.
California-based food provider Pacific International has announced that it will voluntarily recall some 6,141 cartons of the herb cilantro after the FDA alerted the company that it had detected traces of the bacteria salmonella in samples of their product.
A 2009 E. coli outbreak that affected 77 people across 30 states may have been caused by raw flour that was an ingredient in ready-to-cook cookie dough, a new report published in the journal Clinical Infectious Disease has discovered.
A team headed by scientists from the Institute for Research in Biomedicine (IRB Barcelona) reports how the protein Ler, which is found in pathogenic bacteria, interacts with certain DNA sequences, thereby activating numerous genes responsible for virulence, which bacteria then exploit to infect human cells.
Researchers at the University of Leeds have been studying an enzyme – called 3D – which plays a vital role in the replication of the virus behind the disease.
One of the most comprehensive studies to date of the microbes that are found in extremely low-birthweight infants found that hard-to-treat Candida fungus is often present, as well as some harmful bacteria and parasites.
Scientists at The Scripps Research Institute have determined the atomic structure of a protein that the Lassa fever virus uses to make copies of itself within infected cells.

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...
