A new study examines how shared pathogens affect host populations
Many pathogens are able to infect multiple species within a community and are commonly transmitted across species. Cross-species transmission is often associated with pathogen emergence and therefore has been considered as a negative factor for humans, wildlife, and species of agricultural importance. Many pathogens like malaria, Lyme disease or West Nile encephalitis that infect multiple hosts a...New lab technique identifies high levels of pathogens in therapy pool
A research team using a novel genetic cloning and sequencing technique has identified a surprisingly high number of airborne pathogens in a Midwest therapy pool, pointing to the need for closer scrutiny of public hot pools, says a new study. Led by Washington University in St. Louis and involving the University of Colorado at Boulder and San Diego State University, the new study assessed t...Edible bivalves as a source of human pathogens: signals between vibrios and the bivalve host.
Clams, mussels and oysters are important vehicles for the transmission of enteric diseases when consumed raw or undercooked. Vibrio species, including human pathogens, are particularly abundant in bivalve tissues, where they can persist even after cleaning procedures, thus representing a potential risk for human health. Although different environmental factors are well known to affect the persist...Research Reveals Functions Of Harmful Shellfish Pathogens
Providing safer shellfish is the goal of Agricultural Research Service (ARS) scientists who are studying the means by which pathogenic bacteria enter shellfish. In the United States, two pathogenic bacteria from the genus Vibrio are of concern: V. vulnificus and V. parahaemolyticus. These bacteria are naturally found in shellfish and seawater, particularly when water temperatures are warm,...Tagging pathogens with synthetic DNA 'barcodes'
A supermarket checkout computer can identify thousands of different items by scanning the tiny barcode printed on the package. New technology developed at Cornell University could make it just as easy to identify genes, pathogens, illegal drugs and other chemicals of interest by tagging them with color-coded probes made out of synthetic tree-shaped DNA. A research group headed by Dan Luo,...Researchers Develop Technologies to Devour Food Pathogens
Purdue researchers are developing two inexpensive technologies that may be able to prevent future food-borne illness//, such as the recent outbreak of E. coli in contaminated spinach. Together, these technologies rapidly detect and eradicate food-borne pathogens. The first method uses a laser to detect and identify many types of bacteria, and is about three times faster and...Protein Structure of Pathogens Associated With CF and TB Solved
The structure of a novel protein in the bacterium that is the most persistent pathogen in cystic fibrosis (CF) patients has been solved . Hauptman-Woodward Institute scientists Dr. Andrew Gulick, Eric Drake and Dr. Manish Shah, in collaboration with researchers at the University at Buffalo and the New York State Center of Excellence in Bioinformatics and Life Sciences have made this si...Vaginal Pathogens DNA Direct Probes
