Chitosan Derivatives Reduce E. coli and coliform concentrations in models of food contamination (PRWEB) July 15, 2011 New research conducted jointly between Synedgen, Inc, and the School of Environment, Natural Resources and Geography, at Bangor University, Bangor, UK demonstrates that a novel biocompatible and bactericidal chitosan derivative developed by Synedgen offers a rapid and safe method to significantly reduce bacterial counts and inhibit pathogenic activity from dangerous...
Scientists have tested a predatory bacterium "“ Bdellovibrio "“ against Salmonella in the guts of live chickens. They found that it significantly reduced the numbers of Salmonella bacteria and, importantly, showed that Bdellovibrio are safe when ingested.The research was funded by the Biotechnology and Biological Sciences Research Council, carried out by Professor Liz Sockett's team at The University of Nottingham, with Dr Robert Atterbury and Professor Paul Barrow at the University of...
EXTON, Pa., May 19, 2011 /PRNewswire/ -- ViroPharma Incorporated (Nasdaq: VPHM) today announced initiation of a Phase 2 dose-ranging clinical study to evaluate the safety, tolerability, and efficacy of VP 20621 for prevention of recurrence of Clostridium difficile infection (CDI) in adults previously treated for CDI. The objectives of this randomized, double-blind, placebo-controlled, dose ranging study are to evaluate the safety and tolerability of VP 20621 dosed orally for up to 14 days...
Sugar has been found to be an effective and low-cost way to boost the effectiveness of antibiotics for chronic bacterial infections such as staph, strep, tuberculosis and urinary tract infections, researchers say.James Collins, a professor of Biomedical Engineering at Boston University who is also a Howard Hughes Medical Institute investigator and a core faculty member of the Wyss Institute for Biologically Inspired Engineering at Harvard University, and his research team discovered that the...
A fluorescent test systemYou can't see them, or smell them or taste them.They can be in our water and in our food, multiplying so rapidly that conventional testing methods for detecting pathogens such as E.coli, Salmonella and Listeria come too late for the tens of thousands of Canadians who suffer the ill effects of these deadly bacteria.Biochemist Yingfu Li and his research team have developed a simple test that can swiftly and accurately identify specific pathogens using a system that will...
Bacteria that cause pneumonia and meningitis are only able to spread when individuals are infected with flu, says a scientist reporting at the Society for General Microbiology's Spring Conference in Harrogate. The work could have implications for the management of influenza pandemics and could help reduce incidence of pneumococcal infections in very young children, who are more susceptible to disease.Streptococcus pneumoniae normally lives harmlessly in the nasal passage. Up to 80% of young...
Hopkins Children's study suggests antibiotics may not always be best therapyWhen it comes to curing skin infected with the antibiotic-resistant bacterium MRSA (methicillin-resistant Staphylococcus aureus), timely and proper wound cleaning and draining may be more important than the choice of antibiotic, according to a new Johns Hopkins Children's Center study. The work is published in the March issue of Pediatrics.Researchers originally set out to compare the efficacy of two antibiotics...
SANTA MARIA, Calif., Feb. 14, 2011 /PRNewswire/ -- Hardy Diagnostics, an ISO certified biomedical firm, is pleased to announce the release of HardyCHROM(TM) SS, a highly selective chromogenic medium recommended for use as a primary screening medium for the isolation and differentiation of Salmonella and Shigella spp. from stool cultures. These two pathogens can be easily distinguished from non-pathogenic enteric bacteria based on colony color. Differentiation of Salmonella and Shigella spp....
U.S. Department of Agriculture (USDA) scientists have come up with a way to detect pathogenic Escherichia coli and Salmonella bacteria in waterways at lower levels than any previous method. Similar methods have been developed to detect pathogenic E. coli in meat products, but the approach by the scientists with USDA's Agricultural Research Service (ARS) represents a first for waterways.ARS is USDA's principal intramural scientific research agency, and this research supports the USDA priority...
There is an ongoing battle in the "war on terror" that remains mostly unseen to the public -- a race between scientists working to develop a vaccine to protect against plague and the terrorists who seek to use plague as a weapon."Governments remain concerned that bioweapons of aerosolized Yersinia pestis, the bacteria that causes plague, could kill thousands," said Stephen Smiley, a leading plague researcher and Trudeau Institute faculty member.The anthrax scare that followed the terror...

Streptococcus pneumoniae, or pneumococcus, is Gram-positive, alpha-hemolytic, bile-soluble aerotolerant, anaerobic member of the genus Streptococcus. It was recognized as a major cause of pneumonia in the late 19th century and is thus the subject of many humoral immunity studies. It causes many other types of pneumococcal infections other than pneumonia including acute sinusitis, otitis media, meningitis, bacteremia, sepsis, septic arthritis, peritonitis, cellulites, and brain abscess. It...
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...
Staphylococcus aureus is a facultative anaerobic gram-positive coccus, and is the most common cause of staph infections. It is commonly part of the skin flora found in the nose and on skin. Around 20% of the human population is long-term carriers. It gets its golden color due to its carotenoid pigment staphyloxanthin. The pigment acts as a virulence factor with an antioxidant action that allows the microbe to evade death by reactive oxygen species used by the host immune system. Staphylococci...
Haemophilus influenzae is a Gram-negative, rod-shaped bacterium first described in 1892 by Richard Pfeiffer during an influenza pandemic. It is generally aerobic but can grow as a facultative anaerobe. H. influenzae was mistakenly considered to be the cause of influenza until 1933 when the flu virology became apparent. It was the first free-living organism to have its entire genome sequenced. The project was completed and published in 1995. Two major categories were defined: the...
Escherichia coli is a Gram-negative rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms. Most strains are harmless; however, some such as O157:H7 can cause food poisoning in humans and are often responsible for product recalls. The normal flora of the gut normally contains the harmless strains and often provide K2 to the body. They are not always confined to the intestine and have the ability to survive briefly outside of the body. It grows easily...
