Trypanosoma brucei, a protozoan parasite, is the causative agent of African sleeping sickness in humans (T. b. gambiense and T. b. rhodesiense) and nagana in cattle (T. b. brucei). These diseases result in much economic hardship and morbidity in Sub-Saharan Africa. The life cycle of these organi... Read More
Researchers use a protein-lipid complex found in human breast milk to increase the activity of otherwise-ineffective antibiotics against drug-resistant pathogens. A protein-lipid complex that naturally occurs in human breast milk can increase the sensitivity of methicillin-resistant Staphylococc... Read More
In 2010, a study revealed that the main agent of malaria in humans, called Plasmodium falciparum, arose from the gorilla. Today, the vector which transmitted the parasite from apes to humans has just been identified. A Franco-Gabonese research consortium has determined which species of anopheles... Read More
It's a chemical that's been in U.S. households for more than 40 years, from the body wash in your bathroom shower to the knives on your kitchen counter to the bedding in your baby's basinet.
But federal health regulators are just now deciding whether triclosan — the germ-killing ingredient fo... Read More

Raw oysters, a delicacy for foodies and a purported hangover cure (it isn’t) aren’t always the safest thing to eat. Pathogens such as Vibrio vulnificus, norovirus and Hepatitis A sometimes lurk in oyster flesh. These little nasties can cause food poisoning and norovirus specifically has no treat... Read More
If you had heard of glomalin, you are a better person than I am. Until a couple of months ago I wasn’t aware of its existence, which is close to sinful: it happens to be a very abundant protein in the soil rhizosphere, playing a key role in the soil’s mechanical properties and as repository of s...

Deep in the bowels of our, well, bowels, lurk trillions of microscopic bacteria. But don't be fooled by the big bad "B" word, intractably tied to infections and disease. In fact, these bitty bugs do us a world of good.
"There's a certain 'ick' factor associated with gut bacteria," said Lita P... Read More
Trichomonas vaginalis is a protozoan parasite of the urogenital tract in men and women and causes a sexually transmitted disease, trichomoniasis, in about half of infected women. Infections are associated with pelvic inflammatory disease, adverse pregnancy outcomes, infertility, an increased inc... Read More

Researchers at NIAID have devised a method for delivering tumor cell-killing enzymes in a way that protects the enzyme until it can do its work inside the cell. In their study in mBio this week, researchers assembled microscopic protein packages that can deliver an enzyme called PEIII to the ins... Read More
