Did you see this paper in PLoS Computational Biology? It's mind-blowing. U. Maryland researchers found evidence for Acinetobacter and Pseudomonas nucleic acid integrated into human chromosomes and mitochondria, po... Read More
What types of microbes do mothers transmit to their newborns and how universal is maternal microbial transmission throughout animals, including from your mother?
The sterile womb paradigm is an enduring premise in biology that human infants are born sterile. Recent studies suggest that infant... Read More
A new study has revealed that bacteria use a form of communication similar to human language, but employing chemical signals instead of words. This language enables bacteria to thrive and researchers hope that by interpreting it they can develop new drugs to fight infections without bacteria dev... Read More

Methanotrophs (bacteria that use methane for their carbon and energy) secrete siderophore-like compounds that are usually used to chelate copper and make it more bioavailable, but ... Read More
Researchers have found evolved pertussis, as whooping cough is scientifically known, in Finland, France, Italy, Japan and the U.S. As we previously reported, the evolved bacteria don't seem to be more dangerous than their predecessors. Nevertheless, the U.S. Centers for Disease Control and Preve... Read More

There is much interest in the role of nutrients and micronutrients in the support of host defense against infections. However, there is controversy in the ability of supplements to help prevent or treat infections. Speakers discuss research on the role of vitamin D supplements to prevent and/or ... Read More
Colorectal cancer patients have fewer beneficial gut bacteria and more harmful microbes than those without the disease, researchers from the New York University School of Medicine report in Friday’s edition of the Journal of the National Cancer Institute.
While previous research had suggested... Read More
Patients getting medical care can catch serious infections called healthcare-associated infections (HAIs). While most types of HAIs are declining, one -- caused by the bacterium Clostridium difficile --continues to grow. C. difficile causes diarrhea linked to 14,000 American deaths each year. Pa...

A hospital was fined after a pair of neurosurgeons implanted fecal bacteria into the brains of patients during operations without proper authorization. A few things jump out at us here. 1) They did WHAT!?! 2) There’s proper authorization for putting poop in people’s brains!?! 3) Ewwwwwww.
The... Read More

You have the best podcast on the web, hands down. I use your TWiP episodes in both my undergraduate and graduate classes.
I've recently seen a family in Hawaii with recurrent pathogenic Blastocystis hominis and Dientamoeba fragilis a... Read More
A potentially pathogenic fungus has found a home living in extreme conditions in some of the most common household appliances, researchers have found. A new paper published in the British Mycological Society journal, Fungal Biology, published by Elsevier, shows that these sites make perfect habi... Read More
An Ebola outbreak has killed at least 59 people in Guinea, UNICEF said, as the deadly hemorrhagic fever has quickly spread from southern communities in the West African nation.
Experts in the country had been unable to identify the disease, whose symptoms -- diarrhea, vomiting and fever -- we... Read More
Almost 1 out of every 3 people in the United States will develop shingles during their lifetime. Despite the approval and recommendation by the FDA of a shingles vaccine for adults over 50, only 16% of American seniors over 60 are vaccinated. Vaccinations are even lower for those aged 50-60. A... Read More
Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More
