Illicit drug users are at increased risk of being exposed to microbial pathogens and are more susceptible to serious infections say physicians writing in the Journal of Medical Microbiology. The review, which aims to improve the microbiological diagnosis of drug use-related infections, assesses the role of drug related practices in the spread of a range of bacterial, viral, fungal and protozoal infections. The review by collaborators from the Armed Forces Medical College, Pune, India...

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...

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...

New experiments at the University of California, Berkeley, may one day lead to anti-viral treatments that involve swallowing Salmonella bacteria, effectively using one bug to stop another. Researchers at UC Berkeley's School of Public Health have reprogrammed Salmonella, the same foodborne pathogen that can cause diarrhea, fever and abdominal cramps, to safely transport virus-stopping enzymes into cells without causing disease. Not only did this technique effectively treat mice infected with...

The potentially deadly bacterium Salmonella possesses a molecular machine that marshals the proteins it needs to hijack cellular mechanisms and infect millions worldwide. In a paper published Feb. 3 online in Science Express, Yale University researchers describe in detail how Salmonella, a major cause of food poisoning and typhoid fever, is able to make these proteins line in up in just the right sequence to invade host cells. "These mechanisms present us with novel targets that might form...

Airborne prions are also infectious and can induce mad cow disease or Creutzfeldt-Jakob disorder. This is the surprising conclusion of researchers at the University of Zurich, the University Hospital Zurich and the University of Tbingen. They recommend precautionary measures for scientific labs, slaughterhouses and animal feed plants. The prion is the infectious agent that caused the epidemic of mad cow disease, also termed bovine spongiform encephalopathy (BSE), and claimed the life of over...

Scientists at the University of Zurich (Switzerland) and the Federal Research Institute for Animal Health (FLI; Tuebingen) have challenged the notion that airborne prions are innocuous. Details of how inhalation of prion-tainted aerosols induced disease are published January 13 in the open-access journal PLoS Pathogens. It is known that prions can be transmitted through contaminated surgical instruments and, more rarely, through blood transfusions. However, prions are not generally considered...

Findings Point to Normal Prion Protein as Most Effective Therapeutic Target for "Mad Cow" and Related Diseases Scientists from the Florida campus of The Scripps Research Institute have shown that prions, bits of infectious protein that can cause fatal neurodegenerative disease such as bovine spongiform encephalopathy (BSE) or "mad cow disease," have the ability to adapt to survive in a new host environment. In this regard, although they lack DNA and RNA, they behave much like viruses,...

About one in six Americans, or roughly 48 million people, are sickened from with foodborne illnesses each year, according to new estimates released Wednesday from the U.S. Centers for Disease Control and Prevention (CDC). Of those, nearly 3,000 are killed and 128,000 require hospitalization due to their illness, the health agency said. The figures are the first comprehensive estimates since 1999, and are the CDC's first to include illnesses caused solely by foods consumed in the United...

Habitat destruction and species extinction may lead to an increase in diseases that infect humans and other species, according to a paper in the journal Nature co-authored by a University of Florida ecologist. In the paper to be published Thursday, UF biology professor Robert D. Holt and his colleagues reported that by reviewing studies from a wide range of systems, including data from plants, animals and bacteria, they were able to relate dimensions of environmental loss, and in particular...
