Research could help in battle against infections that do not respond to powerful drugs In biology, we often think of natural selection and survival of the fittest. What about survival of the luckiest? Like pioneers in search of a better life, bacteria on a surface wander around and often organize into highly resilient communities, known as biofilms. It turns out that a lucky few bacteria become the elite cells that start the colonies, and they organize in a rich-get-richer pattern...
Two genome-wide association studies and a subsequent meta-analysis have found that certain genetic variations are associated with susceptibility to Helicobacter pylori, a bacteria that is a major cause of gastritis and stomach ulcers and is linked to stomach cancer, findings that may help explain some of the observed variation in individual risk for H pylori infection, according to a study in the May 8 issue of JAMA. "[H pylori] is the major cause of gastritis (80 percent) and...
To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells. In a study to be published May 7 in mBio®, the online open-access journal of the American Society for Microbiology, scientists at Emory University School of Medicine, the University of Virginia, and Universidad de las Islas Baleares in Mallorca, Spain, uncover this...
WASHINGTON, April 30, 2013 /PRNewswire-USNewswire/ -- The National Turkey Federation (NTF) strongly disputes the misleading findings of a Consumer Reports article about ground turkey, which makes a number of alarming claims based on an extremely small sampling of ground turkey products. "Consumer Reports had the opportunity to foster a serious, thoughtful discussion about food safety, but instead it chose to sensationalize findings and mislead people," said NTF President Joel...
In a study that included nearly 3,000 adults from Denmark, a diagnosis of meningococcal, pneumococcal, or Haemophilus influenzae meningitis in childhood was associated with lower educational achievement and economic self-sufficiency in adult life, according to a study in the April 24 issue of JAMA. Bacterial meningitis may lead to brain damage due to several factors, and survivors of childhood bacterial meningitis are at particular risk of hearing loss, seizure disorders, motor deficits,...
Legionella consulting services expands with Special Pathogens Laboratory hire of Frank P. Sidari III, PE, BCEE. Experienced in evaluation and disinfection of potable water systems with respect to Legionella, Sidari published the first field evaluation of chlorine dioxide disinfection of a hospital campus water system to control Legionella pneumophila in the Journal of the American Water Works Association. Pittsburgh, PA (PRWEB) April 22, 2013 Special Pathogens Laboratory...
Numerous epidemiologic studies have shown that a diet high in salt is associated with an increased risk of gastric cancer. Now Timothy L. Cover and colleagues of Vanderbilt University show that high dietary salt combined with infection by the ulcer-causing bacterium Helicobacter pylori greatly increases the risk of cancer. The study was published ahead of print in the journal Infection and Immunity. In the study, the researchers infected Mongolian gerbils with H. pylori. One set of gerbils...
UT Southwestern Medical Center researchers report that a pathogen annually blamed for an estimated 90 million cases of food-borne illness defeats a host's immune response by using a fat-snipping enzyme to cut off cellular communication. "Our findings provide insight into severe bacterial infectious diseases, as well as some forms of cancer, in which the attachment of fat molecules to proteins is an essential feature of the disease process," said Dr. Neal Alto, assistant professor of...

Wolbachia is a genus of bacteria which infects arthropod species, including a high proportion of insects (~60% of species). It is one of the world's most common parasitic microbes and possibly the most common reproductive parasite in biosphere. Studies have suggested that 25-70% of all insect species are estimated to be potential hosts. Marshall Hertig and Burt Wolbach first identified the bacterium in 1924 in a species of mosquito. Hertig described the genus as Wolbachia pipientis. Not...
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...
Salmonella enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella and many of the pathogenic serovars of the S. enterica species are in this subspecies. Serovars can be designated fully or in a shortened form. The genus, Salmonella, is on the short form lists which are followed by the capitalized and non-italicized serovar. Each serovar can have many strains as well, which allows for a rapid...
Rickettsia rickettsii is a gram-negative bacterium native to the New World and causes the malady known as Rocky Mountain spotted fever (RMSF). It is transmitted through the bit of an infected tick when it feeds on animals and humans. Humans are not necessary hosts in the rickettsia-tick life cycle but they can be. S. Burt Wolbach created the first detailed description of the etiologic agent in 1919. He recognized it as an intracellular bacterium seen most frequently in endothelial cells....
Pseudomonas aeruginosa is a common bacterium that can cause disease in animals and humans. It can be found in soil, water, skin flora, and most man-made environments throughout the world. It thrives in normal or hypoxic atmospheres; due to this it has colonized many natural and artificial environments. It can infect animals with damaged tissue or people with reduced immunity. Symptoms are generalized inflammation and sepsis. It can be fatal if colonization occurs in critical body organs,...
