Colonization by the human and animal parasite, Giardia, changed the species composition of the mouse microbiome in a way that might be harmful.

Collecting, transporting, and storing patient specimens plays a major role in infection diagnoses. ASM provides a number of resources regarding best practices and the latest research regarding specimen collection!

Researchers report they have used the Pathogen Box to identify a novel, highly potent antifungal agent with activity against two of the most common fungal pathogens of humans.

Using the Pathogen Box, an open-source drug discovery project, researchers have identified a novel, highly potent antifungal agent with activity against two of the most common fungal pathogens of humans: Cryptococcus neoformans and Candida albicans.

Tigecycline is an antibiotic of last resort—one that is used when all others have failed. Now a team of Spanish investigators has identified the first documented example of tigecycline-resistant bacteria in hospital that are adapted to living on companion animals—in this case, dogs.

The first ever peer-reviewed test of decontamination devices for car interiors has been completed. The quickest device took one and a half hours to remove pathogenic microbes from interior air. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology

Simon Anthony has spent his scientific career studying viruses and their impact on health. In the United Kingdom, where he is from, he investigated viruses of agricultural significance. Then, at the San Diego Zoo, he focused on the microbes of wildlife. Currently, at Columbia University’s Mailman School of Public Health and its Center for Infection and Immunity, he studies viruses that spill over from animals into people.

Hepatitis B is notoriously difficult to eradicate with currently available agents..  Now, in a new study, a novel form of “pegylated” interferon-β has reduced hepatitis B virus (HBV) infections in experimental human-derived cells and in mice more effectively than the conventional pegylated interferon-α2a, suggesting that it could lead to improved treatment for hepatitis B infection in humans. The research is published in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.

 

A team of researchers in the United States and Uganda has identified a novel coronavirus in a bat from Uganda that is similar to the one causing Middle East Respiratory Syndrome (MERS) in people, giving further credence to the theory that such viruses originate in bats. The work, part of the United States Agency for International Development’s (USAID’s) Emerging Pandemic Threats PREDICT project, was described this week in mBio®, an online open-access journal of the American Society for Microbiology.  

The decreasing trend of surgical-site infections demonstrates the seriousness with which medical practitioners and clinical microbiologists are taking this issue. This post provides resources on prevention and diagnoses of surgery-related infections, including a specific case of infection due to contaminated heart-lung machines.
