Take two poisonous mushrooms, and call me in the morning. While no doctor would ever write this prescription, toxic fungi may hold the secrets to tackling deadly diseases.
A team of Michigan State University scientists has discovered an enzyme that is the key to the lethal potency of poisonou... Read More
Polyethylene is one of the most popular and, unfortunately, persistent types of plastics. Bags, bottles, and packaging made from the polymer accumulate in landfills and oceans across the globe. Scientists lament that microbes can’t chew up the plastic to render it harmless. However, a new study ... Read More

Scientists are concerned about what they're seeing so far this flu season, the director of the Centers for Disease Control and Prevention said Thursday, a day after the agency advised doctors this year's flu vaccine is not as effective because the current strain of the virus has mutated.
Dr. ... Read More
Sputum specimen from sick of fibrosis cystic can hold many microbes and yeast. This specimen sent to our laboratory Mycobacteriology of Polyclinic University of Messina for mycobacteria research, shows yeast cells with Ziehl-Neelsen stain. Read More
Everybody and his uncle, it seems, has an idea of something that might work to cure people infected with the deadly virus.
When it comes to treatments for Ebola, there has been a nearly four-decade-long drought. Nothing in the medical arsenal attacks the virus directly. For the most part, p... Read More
Scientists have released details of a raft of new chemicals with potent anti-malarial properties which could open the way to new drugs to fight the disease.
A new paper in PNAS is the third published recently by a group at the Australian National University (ANU). The group has collaborated w... Read More
Researchers at North Carolina State University have for the first time mapped human disease-causing pathogens, dividing the world into a number of regions where similar diseases occur.
The findings show that the world can be separated into seven regions for vectored human diseases – diseases ... Read More
Plastic is well-known for sticking around in the environment for years without breaking down, contributing significantly to litter and landfills. But scientists have now discovered that bacteria from the guts of a worm known to munch on food packaging can degrade polyethylene, the most common pl... Read More
This is a picture of the Christmas tree in the University of Colorado Hospital Microbiology Department.
The tree is adorned with homemade culture plate ornaments (one for each staff member) and topped with a stuffed Staphylococcus aureus microbe. Read More
Large TSA plate: yellowish organism is Staph aureus, red organism is Serratia marcescens. Grown for 24 hrs at 37 degrees C. Read More
It is a fascinating quirk of nature: Simple bacteria have an immune system with a memory, which allows them to destroy invading viruses they have encountered in the past.
The phenomenon is more than just a scientific curiosity. In just two years, scientists have discovered how to repurpose th... Read More
Here's an Ebola puzzle for you: If the virus isn't airborne, why do doctors and nurses need to wear full protective suits, with face masks, while treating patients?
After we dug through studies and talked to scientists, the answer slowly emerged.
Ebola does spread through the air. But not ... Read More
A team of scientists has revealed how certain harmful bacteria drill into our cells to kill them. Their study shows how bacterial ‘nanodrills’ assemble themselves on the outer surfaces of our cells, and includes the first movie of how they then punch holes in the cells’ outer membranes. The rese... Read More
Researchers at Tufts University, in collaboration with a team at the University of Illinois at Champaign-Urbana, have demonstrated a resorbable electronic implant that eliminated bacterial infection in mice by delivering heat to infected tissue when triggered by a remote wireless signal. The si... Read More
Diagnosing HIV and other infectious diseases presents unique challenges in remote locations that lack electric power, refrigeration, and appropriately trained health care staff. To address these issues, researchers funded by the National Institutes of Health (NIH) have developed a low-cost, elec... Read More
In order to infect a host cell and proliferate, some viruses, such as the hepatitis C virus, infiltrate the ribosomes, the molecular machines that assemble the proteins present in each of our cells. Viral proteins are thus produced to the detriment of cellular proteins. A group of scientists in ... Read More
This is a picture of Echinococcus granulosus from an infected liver specimen recently received in our laboratory. It is pictured in a saline wet mount at 40X magnification. The picture shows an evaginated scolex from an immature worm with hooklets.
The adult worm of Echinococcus granulosus l... Read More
Dec. 1 has been World AIDS Day since 1988 — but though the awareness and activism around the diseases has changed drastically during the years between then and now.
To see just how much our understanding and attitudes have evolved, take a look back at TIME’s coverage of AIDS through these sev... Read More
New coatings to apply to soft cheese have been developed by researchers. These coatings are totally edible and have an antimicrobial capacity, which increases the lifespan of the cheese. These films incorporate oregano and rosemary essential oils as antimicrobial agents, and chitosan, a by-produ... Read More
