Action of Modern Drug Demonstrates How Two Ancient Human Systems Interact Jun 19, 2010
During severe sepsis, which accounts for about 210,000 deaths annually in the US, the complement system is part of the primary response to an invading pathogen. However, both the complement and the coagulation systems can work overtime during sepsis, leading to multiple organ failure and death. (Science Daily)

Since plants are fixed in place and cannot move to elude their attackers, they have developed an elaborate array of chemical defenses to protect themselves from herbivores and pathogens ... They remain inactive, however, until their activation is triggered by the attack of an herbivore, such as an insect or a pathogen. (Suite101.com)
Humanure: Goodbye, Toilets. Hello, Extreme Composting Jun 18, 2010
Wastewater treatment is much more energy-intensive than composting, which needs little more than time (about a year) for complete decomposition and pathogen elimination. In Austin, Texas, a sustainably minded nonprofit called the Rhizome Collective succeeded this year in getting the city to approve what may be the first legal composting toilet in the U.S. "The hypocrisy is amazing," says Lauren Ross, 54, a civil engineer involved in Rhizome's four-year battle to get a permit.

Detection of MRSA in Cystic Fibrosis Patients Associated With Shorter Survival Jun 18, 2010
The results of this study, in conjunction with previous data, further establish MRSA as a significant CF pathogen and provide impetus for more aggressive treatment of CF patients who are persistently MRSA positive. Ideally this treatment will be conducted in the context of clinical trials, because optimal therapeutic approaches for MRSA, both persistent and new, are not yet known. (Science Daily)
Gene-Based Detection Method Might Spot HIV Earlier Jun 17, 2010

The scientists isolated H5N1-specific antibodies from consumers' eggs sold in Vietnam, where hens are vaccinated against the pathogen, and tested them against infections with H5N1 and related H5N2 strains in mice. When delivered into the nose before infection, the antibodies from the egg yolk prevented the infection. (Science Daily)
The bacteria strain belongs to the plant pathogen species Pseudomonas syringae ... "Because the bacterium we isolated and sequenced is nonpathogenic itself but is very similar to pathogens, we can compare its genome to the genomes of the closely related pathogens and see what mechanisms bacteria use to cause disease and how bacteria evolve to become pathogens," Vinatzer said ... a graduate student in the Department of Plant Pathology, Physiology, and Weed Science, are now trying to determine...

Staphylococcus aureus is the second most common pathogen causing health care-associated infections in the United States, and 49 percent of those infections are caused by the highly antibiotic-resistant bacteria MRSA. A strain called USA100 is the most common type of MRSA involved in health care-associated infections in U.S. hospitals. In this study, 444 nose cultures of 2,055 patients from 13 enrollment centers resulted in growth of MRSA. The researchers found that 14 percent and 15 percent of... (EurekAlert!)
CHICAGO, April 20, 2010 The Field Museum and the University of Chicago today announced the establishment of the Emerging Pathogens Project, a unique research program to study the evolution of species-switching parasites or pathogens that result in diseases such as bird flu, malaria, and AIDS. Many diseases have a long infection history in animals. The project's goal is to provide in-depth, baseline information on pathogens that appear in animals, eventually leading to important clues for how... (EurekAlert! -- Business News)
"We closed all of the park's 17 caves and two mine complexes to any public entry a year ago to prevent the possible importation of the WNS pathogen on visitor's clothing or gear, but scientists have confirmed that bat-to-bat transmission of the fungus occurs," said Bill Stiver, a wildlife biologist at the park. "We take this very seriously because national parks are often the primary refuge that endangered species can count on for protection," Stiver said. (CBS News -- Sci/Tech)
