A major new class of antibodies that can make the four different types of dengue virus (DENV) non-infectious has been discovered by a group of international researchers, including from the University of Melbourne.
The discovery could lead to the development of better vaccines and laboratory t... Read More
Scientists looking to understand – and potentially thwart – the influenza virus now have a much more encompassing view, thanks to the first complete structure of one of the flu virus’ key machines. Knowing the structure allows researchers to finally understand how the machine works as a whole, a... Read More
When most people look at soil, they just see dirt. When I look at soil, I see billions of microorganisms crawling atop one another, consuming the dead in a feasting frenzy that stops for nothing save a deep freeze. I see microbes and their enzymes, the digestive juices that break down, transform... Read More
The bed bug may be just as dangerous as its sinister cousin, the triatomine, or “kissing” bug. A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi, the parasite that ...

Researchers at the University of Virginia School of Medicine studying a potentially deadly parasitic infection have discovered a previously unknown way that human cells are killed, with the parasitic amoeba essentially nibbling cells to death – as a piranha might attack its prey.
Until now, r... Read More
Switchgrass successfully removed up to 40 percent of the PCBs from contaminated soils in lab experiments. When a PCB-oxidizing microorganism joined in, the removal rate reached 47 percent.
The researchers investigated how adding an aerobic PCB-oxidizing microorganism could enhance the oxidati... Read More
A scientist with a swab and a microscope could tell what school you went to. Trillions of microbes live in and on our body. We don’t yet fully understand how these microbial ecosystems develop or the full extent to which they influence our health. Some provide essential nutrients, while others c... Read More
Sexual biology may be the key to uncovering why Anopheles mosquitoes are unique in their ability to transmit malaria to humans, according to researchers at Harvard T. H. Chan School of Public Health and University of Perugia, Italy. Through analysis of 16 Anopheles genomes, they found that these... Read More
Over the last few weeks, the numerous outbreaks of measles in Canada have led many public health officials and microbiologists to shake their collective heads. The reason is simple: this should not be happening. Of all the pathogenic viruses, this one has been on our radar for nearly 200 years a... Read More
The American Society for Microbiology hosted a live podcast of This Week in Virology with Vincent Racaniello with co-host Alan Dove that includes guests Paul Duprex, Director of Cell and Tissue Imaging Core, Boston University, National Emerging Infectious Diseases Laboratories (NEIDL), and Ju...

For practically our whole history of cooking and eating, we've gotten our spices and most flavors (not to mention all of the other basic nutrients that keep us alive) straight from plants.
But researchers and biotech companies are starting to produce some of these nutrients and flavors — espe... Read More
The fungal pathogen Candida albicans causes yeast infections, diaper rashes and oral thrush, and is the most common fungal pathogen to infect humans. Researchers have identified a protein that the fungus uses to defend itself against the human body. Another concern with the fungus is that it can... Read More
Novel test could slash wait time and curb inappropriate prescriptions.
Antibiotic resistance, which transforms ordinary microbes into menaces that cannot be easily controlled, is exacting a growing toll on the human population. More than two million people in the U.S. develop drug-resistant i... Read More
Natural disasters such as earthquakes can have far-reaching effects beyond the damage caused on the day they occur. The 2010 earthquake in Haiti damaged the already limited sanitation systems leading to areas without adequate toilet and washing facilities; perfect for the spread of infection dis... Read More
A four-year EU-funded project has identified new ways of cultivating marine microorganisms and screening them for potentially useful marine bio-compounds. This could have implications for the healthcare, cosmetics and pharmaceutical industries, which are just a few of the sectors that are eager ... Read More
The first case of Ebola in the United States was announced today, with a patient in Dallas who traveled to the US from Liberia. The resultant hysteria and xenophobia prompts this reminder. There is NO need to panic.
Ebola is NOT transmitted before a patient develops symptoms. Ebola is transmi... Read More
A group of researchers at the Max F. Perutz Laboratories has created one of the three world's largest gene libraries for the Candida glabrata yeast, which is harmful to humans. Molecular analysis of the Candida glabrata fungus mutations led to the discovery of 28 new genes that are partly respon... Read More
A virus not known to cause disease kills triple-negative breast cancer cells and killed tumors grown from these cells in mice, according to Penn State College of Medicine researchers. Understanding how the virus kills cancer may lead to new treatments for breast cancer.
Adeno-associated virus... Read More
The slide was prepared from blood of infected animals (cattle). The smear was stained with poly-chrome methylene blue which demonstrated blue colored bacillary body and light pink colored capsule (McFadyean's reaction).
The animal had the symptoms of high fever, convulsion and sudden death. ... Read More
The human body doesn’t like outsiders. When a foreign pathogen or substance, say an unwanted virus, finds its way into our blood streams we produce antibodies that the neutralize the threat. These “Y”-shaped proteins are made by a class of white blood cells called plasma cells and bind to molecu... Read More
