A sample of Proteus mirabilis was inoculated on to a TSA plate by taking a sterile swab and placing a drop in the center of the plate. The plate was then incubated at 37 degrees for 8 hrs. Swarming motility can be seen as a clear halo and finger like projections coming from and around the grow... Read More
A streak plate of Strep pyogenes on blood agar, stock culture used for class, was kept at room temp for 1 month. Before disposal a contaminant, presumably environmental, was seen on the plate. The pigment was opaque tan/yellow and with a mucoid surface. Lobate marigins with raised irregular-rh... Read More
Vincent and Dickson welcome new TWiP host Daniel Griffin to discuss the association of a new Mycoplasma with trichomoniasis, and to introduce a new feature to the show, a case study.
Hello Dr Racaniello and Despommier,
I recently saw an article about the paper linked below on Science Daily and thought it might be worth a discussion on TWIP. It is about the possibility of bed bugs being a vector for T. cruzi. I would love to... Read More
To slip, slide, squeeze and otherwise invade different parts of the body, cancer cells learn to switch between two modes of moving usually used by healthy cells. Now we know how.

An antibiotic with the ability to vanquish drug-resistant pathogens has been discovered — through a soil bacterium found just beneath the surface of a grassy field in Maine. Although the new antibiotic has yet to be tested in people, there are signs that pathogens will be slow to evolve resistan... Read More
The polio eradication and endgame strategic plan announced by the World Health Organization in 2014 includes at least one dose of inactivated poliovirus vaccine (IPV). Since 1988, when WHO announced the polio eradication plan, it had relied exclusively on the use of oral poliovirus vaccine (OPV)... Read More
The National Institutes of Health has awarded grants totaling $7.9 million in 2014 to 25 research teams who are unraveling the workings of single cells, as part of an effort to spur development of personalized treatments that target disease at the cellular level. The grants are supported by the ... Read More
You can see clearly in this picture how the red cells are destroy by the bacteria, creating this amazing effect in the agar. What bacteria do you think it is?? Read More
An improved gene therapy strategy using modified human stem cells shows promise in animal models as a functional cure for HIV.

Just when we think we know everything, a story comes along to remind us that there is something fundamental--and seemingly elementary--that we still haven't figured out. “Why are we the size we are? Why are our organs the size they are? Why are the cells in those organs a stereotypical size? Wha... Read More
Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube.
Using this method, scientists learned that populations ... Read More

The bacteria that cause cholera grab genes from other organisms in a particularly predatory and precise way, new research finds: They spear neighboring cells with a kind of poison-tipped spike.
Bacteria often grab genes from other organisms and incorporate that DNA into their own genomes. But... Read More
With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades -- such as pneumonia or urinary tract infections -- are proving trickier to treat with standard antibiotics.
New drugs are desperately needed, but so are ways to maximize the effective lif... Read More
A new class of compounds may be an effective way to fight a virus that leaves children with serious respiratory infections and might be associated with polio-like symptoms.
Researchers used a technique called X-ray crystallography to learn the precise structure of the original strain of enter... Read More
The TWiV gang reviews ten fascinating, compelling, and riveting virology stories from 2014.
Shown here is a picture of a hookworm egg found on a concentrate in an ova & parasite exam
Human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. These species have indistinguishable eggs and can only be distinguished by their larvae.
Infective larvae g... Read More
