Vincent and Dickson discuss the spread of P. knowlesi in Malaysia, and how Leishmania parasites protect the sandfly gut from bacterial infection.
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

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
The current Ebola virus outbreak in West Africa has sickened over 14,000 people and has killed over 5,100. Health workers from around the world are attempting to halt this deadly disease. On November 19th, the American Society for Microbiology featured two of these health workers, Dr. Joseph ... 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
Laurene Mascola's distinctive voice and laugh has won my heart this month. I found that when TWiM came up for the third time in my playlist the last couple weeks, I kept listening just for a fix. She should be a star.
I'm glad you had a good reaso... Read More

Have you thanked a vulture today? It turns out that they're getting rid of an awful lot of dangerous bacteria for us. According to new research published Tuesday in Nature Communications, the vulture has a gut designed to kill off the bacteria that thrive on the carrion they crave. When they cho... Read More
I came across this paper and thought it sounded interesting for a discussion on TWiP:
Colonisation resistance in the sand fly gut: Leishmania protects Lutzomyia longipalpis from bacterial infection
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
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
