Vincent, Dickson, and Daniel solve last week's case study, present a new one, and reveal how secreted proteins from a helminth prevent diabetes in mice.
Dear Vincent, Dickson and Daniel,
I like your idea of a TWIP coffee mug prize (or maybe a mug discount).
In this second case study you presented, the present symptoms are pretty vague, but his history is interesting. Also since with ... Read More
Animal associated S. aureus are distinct from human strains but some recent studies suggested the human infection caused by animal origin strain of MRSA. Extensive and unregulated use of antibiotic in animal husbandry might be one of the causes for development of multidrug resistant strain. Tran... Read More

Dr. Vincent Racaniello is the Higgins Professor of Microbiology and Immunology at the college of Physicians and Surgions of Columbia University. Along with his academic research, he is known for expanding knowledge with great contributions through his virology blog virology.ws, and his wide podc... Read More
If the reader does not believe that viroids and satellites are distinctive, then surely prions, infectious agents composed only of protein, must impress.
The question of whether infectious agents exist without genomes arose with the discovery and characterization of infectious agents associat... Read More
Paul Duprex joins the TWiV team to discuss the current moratorium on viral research to alter transmission, range and resistance, infectivity and immunity, and pathogenesis.
Vincent, Dickson, and Daniel provide the solution to last week's case study, present a new one, and discuss how immune suppression by nematodes increases tuberculosis fatality in African buffalo.
Dear Vincent & Dickson… and Daniel,
I always enjoy listening to TWIP here in Kona, Hawaii.
Our weather today is 79ºF and clear but we have just experienced a record 25-year overnight low of 54ºF,
Satellites are subviral agents that differ from viroids because they depend on the presence of a helper virus for their propagation. Satellite viruses are particles that contain nucleic acid genomes encoding a structural protein that encapsidates the satellite genome. Satellite RNAs do not encod... Read More

Genomes of non-defective viruses range in size from 2,400,000 bp of dsDNA (Pandoravirus salinus) to 1,759 bp of ssDNA (porcine circovirus). Are even smaller viral genomes possible? The subviral agents called viroids provide an answer to this question.
Viroids, the smallest known pathogens, ar... Read More

The TWiVers review the outcomes of two recent phase 3 clinical trials of a quadrivalent dengue virus vaccine in Asia and Latin America.
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
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
