This video shows the process of injecting a a construct with gene manipulated DNA into a C. elegans worm. The outcome in this case was the rolling worm with the green fluorescent protein in it that localized to the body wall muscle, giving the worm the four green stripes along his body. Read More
Many protozoan parasites (Trichomonas, Leishmania, Giardia, Plasmodium, Entamoeba, Nagleria, Eimeria, Cryptosporidium) are infected with viruses. These viruses do not infect vertebrates, but their double-stranded RNA genomes are sensed by the innate immune system, leading to inflammatory complic... Read More
It causes human mucormycosis and bovine mycotic abortion.
It is distinguished from R.arrhizus by its shorter stalk, and smaller sporangia and spores.
Var.oligosporus : has elongated columellae ; spores less obviously striated.
Var.rhizopodiformis : has ... Read More
Host: Jeff Fox with special guest, Alexander Mankin and Michael Jewett.
Alexander Mankin –called Shura --of the University of Illinois, Chicago, and Michael Jewett at Northwestern University talk with Jeff Fox about their recent success in joining the 30S and 50S bacterial riboso... Read More
When I am asked to name the most lethal human virus, I never hesitate to name rabies virus. Infection with this virus is almost invariably fatal; just three unvaccinated individuals have been known to survive. New evidence from humans in the Peruvian Amazon suggests that the virus might be less ... Read More
This is fun, and although I'm sure someone will gripe about Dicksons enthusiastic response to the crayfish, it made my life easier. I think it's Paragonimus kellicoti. As for eating raw crayfish; how drunk... Read More
The Virtual Museum of Bacteria is a website that presents curated links about bacteria, embedded in informative articles. The website is up and running since 1998, making it one of the oldest websites on the internet. The texts are kept simple, though the collected links vary from simple to adva... Read More
Hi Vincent and Dickson,
I was listening to the new episode of TWiP (episode 52) and one of your listeners wrote in asking about tree parasites. While plant parasite is not my main field of research, I have written about one such pa... Read More
The TWiVers discuss the growing Ebola virus outbreak in West Africa, and an epidemic of respiratory disease in the US caused by enterovirus D68.
Fragments of an abundant protein produced by the prostate form amyloid fibrils that enhance infection of cells by human immunodeficiency virus type 1. These fibrils, called semen-derived enhancer of virus infection (SEVI), have been found to boost infection of prostate cells by the retrovirus XM... Read More
Parasitic wasps inject their eggs into lepidopteran hosts, where they carry out their developmental stages. Along with the eggs, the wasps also deliver viruses carrying genes encoding proteins which inhibit caterpillar immune defenses. Some of these genes are permanently transferred to the lepid...

There is no evidence for further spread among humans of a novel coronavirus recently isolated from two individuals with severe respiratory illness. This conclusion has been drawn after scrutinizing the travels (figure) and contacts of a Qatari adult who was transferred to intensive care in Londo... Read More
Documents designed by the CDC to provide information for planning and conducting school-located 2009 H1N1 influenza vaccination clinics that target school-aged children enrolled in school and potentially other groups in the community. The targeted audience for these materials is primarily state ... Read More
A deep sequencing study of commercially available probiotics, and design and synthesis of a minimal bacterial genome are the topics tackled by Vincent, Michael, and Michele on this episode of TWiM.
Elio Schaechter from the Small Things Considered blog has brought to our attention a new internet resource called Bionumbers. "It enables you to find in a minute (or less) any common biological... Read More
With the advent of the rapid spread of H1N1 it is often a challenge to explain the need to be vigilant about hand hygiene. CNN's Randi Kaye reporting on Anderson Cooper 360 reports on how germs from one sneeze can spread to hundreds, maybe thousands. The video has a great animation and illustr... Read More
