By manipulating the way bacteria "talk" to each other, researchers at Texas A&M University have achieved an unprecedented degree of control over the formation and dispersal of biofilms – a finding with potentially significant health and industrial applications, particularly to bioreactor technology. Working with E. coli bacteria, Professor Thomas K. Wood and Associate Professor Arul Jayaraman of the university's Artie McFerrin Department of Chemical Engineering have employed specific...
England’s Food Standards Agency (FSA) recently issued a statement saying that store-bought eggs can still be safely consumed within “a day or two” of their expiration date “provided they are cooked thoroughly.” This represents a reversal of its previous advice that expired eggs should be discarded due to the risk of salmonella poisoning. The British press noted that the announcement is part of a larger campaign to reduce food waste and the costs associated with it. According to...
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, according to dental researchers at Case Western Reserve University. Yiping Han, professor of periodontics at the Case Western Reserve School of Dental Medicine, made the discovery in her continued work with the Fusobacterium nucleatum bacterium, one of the most...
Single-celled bacteria communicate with each other using coded messages to coordinate attacks on their targets. Until now, the diversity of codes employed by these invading bacteria was thought to be extremely limited. However, a new report published Dec. 12 in PLoS ONE reveals bacterial communication by a novel, previously undescribed signal type – and, as is often the case in evolutionary stories, some plants have evolved a complementary cypher-breaking detection system that intercepts...
California-based food provider Pacific International has announced that it will voluntarily recall some 6,141 cartons of the herb cilantro after the U.S. Food and Drug Administration (FDA) alerted the company that it had detected traces of the bacteria salmonella in samples of their product. While there have been no reports of illness yet, the company has requested that anyone who purchased their cilantro between November 16 and December 10 please return it to the supermarket where they...
New wireless sensor device rapidly detects E. coli in water samples Fecal contamination of public beaches caused by sewage overflow is both dangerous for swimmers and costly for state and local economies. Current methods to detect Escherichia coli, a bacterium highly indicative of the presence of fecal matter in water, typically require 24-48 hours to produce a result. A new, accurate, and economical sensor-based device capable of measuring E. coli levels in water samples in less than 1-8...
Researchers are slowly creating a blueprint for the molecular machine that keeps the pathogen alive and well in the acidic stew of the guts of half the world's population A research team led by scientists at the Chinese University of Hong Kong is releasing study results this week showing how a bacterium, Helicobacter pylori, that causes more than half of peptic ulcers worldwide and that has been implicated in stomach cancer has managed for eons to turn the acidic environment of the human...
Salmonella attorneys at Marler Clark have filed a lawsuit on behalf of a woman and her daughter who were made ill in a Salmonella outbreak linked to pine nuts. Rochester, NY (PRWEB) November 29, 2011 Marler Clark, the nation’s leading law firm dedicated to representing victims of foodborne illness, in conjunction with Rochester-based law firm Underberg and Kessler, has filed a lawsuit on behalf of a Rochester mother and daughter who were made ill with Salmonella after eating pine...
LANSING, Ill., Nov. 22, 2011 /PRNewswire/ -- In the wake of news about food safety concerns regarding eggs, it's important for consumers to know their options for safe eggs during the holiday meal season. National Pasteurized Eggs (NPE), which produces Davidson's Safest Choiceä pasteurized shell eggs, offers a safe, salmonella-free solution for consumers worried about food safety. An FDA investigation recently found serious safety violations and unsanitary...
New publication demonstrates ability of Avidocin™ proteins to prevent and treat E. coli O157 diarrhea in animal study A novel antibacterial protein targeted against E. coli O157:H7 may offer a way to prevent or treat serious food-borne bacterial infections, as demonstrated in a study published in the December issue of Antimicrobial Agents and Chemotherapy. Results in an animal model of E. coli infection showed that the orally administered protein, developed by AvidBiotics, Inc., could...

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,...
