This episode: Inactivated virus particles may treat cancer or even vaccinate against it!
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...

New Massive Online Open Courses (MOOC) in Spanish about Pandemics and new viral infections.
This is a mini online open course about basic concepts of virus and pandemics. We answer questions as what is a virus?, how a virus multiplies inside a cell?, what is a pandemic?, why appear new influe... Read More
Organisms grown on MacConkey Agar at 37 degrees for 24 hours.
-Important Ingredients: crystal violet, bile salts, neutral red (color indicator), lactose
-Differential: used to identify and isolate lactose fermenting G- enteric bacteria mainly Enterobacteriaceae. Strong lactose fermentation pr... Read More
Recently, the discovery that certain bacteriophage encode bacterial gene silencing systems (CRISPR) that can counteract host defense systems demonstrated how mind boggling the evolutionary pathways between phage and bacterial host actually are. In this publication, these relationships are exten... Read More
This episode: Spraying cyanobacteria could turn deserts into useful land!
(9.3 MB, 10.13 minutes)
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
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
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
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
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
I listened to the latest TWIP this morning. Dickson mentioned the herbicide atrazine but thought it was a fungicide. It is actually a herbicide in the photosynthesis inhibitor class. Another bit of trivia about ag chemicals is that old chemicals like ... Read More
I really enjoyed hearing about Carl Woese in TWiM #50. You mentioned the controversy surrounding of Woese's 1977 discovery of Archea as a third domain of life, as it contradicted entrenched scientific beliefs. Although Archea soon foun... Read More
Vincent, Rich, and Kathy and their guests Clodagh and Ron recorded this episode at the 33rd annual meeting of the American Society for Virology at Colorado State University in Ft. Collins, Colorado.
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
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
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.
