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
This episode: Some insects have bacterial symbionts with super-small genomes inside their cells, and some of these symbionts have their own internal bacterial symbionts!
A gastrointestinal pathogen associated with fecal contamination was present in 97 of 129 water samples taken from four beaches on the Lake Erie coast of Ohio according to research published in the August issue of Applied and Environmental Microbiology (click source to download a .pdf of the jour...

When I began listening to TWIV almost a year ago, I had just switched majors from philosophy to biology. I am now writing to you good people at TWIM at the end of my first undergraduate summer research gig, where I have had qui... Read More
This is a database of Herpes simplex (HSV-1) host/viral interactions hosted at WikiGenes. It provides a global snapshot of what the virus does in different compartments at all stages of the viral life-cycle from entry to exit. The database is interactive, and any researcher can edit the page or ... Read More
Merry Youle of the Small Things Considered blog has a new post up that looks at the phage-encoded holin timer and its function in a lytic infection.
"Holins are the smallest known biological timers. Timers, not clocks. Timers tick along, then go off after the specified interval. These small, ... Read More
