Molecular diagnosis is creeping into many areas of bacteriology, but the diagnosis of wound infection remains "stubbornly" culture based. What are the barriers to using molecular methods on wound swabs, and are there any potential solutions?... Read More
This episode: Viruses infecting photosynthetic bacteria could transfer immunity to other viruses between their hosts!
(6.8 MB, 7.4 minutes)
The TWiVaniellos discuss a thermostable poliovirus empty capsid vaccine, and two cell genes that act as a switch between entry and clearance of picornavirus infection.
Star Wars – an epic story of war between the forces of good and evil in a galaxy far, far away. The Death Star – the ultimate weapon of destruction. The story is science fiction, but it could be considered an analogy for the constant battle between our immune system and microbial pathogens. Beli... Read More
It has been assumed that mothers pass on gut microbes to their infants during and just after delivery, a process called vertical transmission, but because of technical restraints, the evidence of this occurring has been limited. Previous cultivation-free studies have observed the same microbial ... Read More
New research conducted at the University of Miami in Coral Gables, Florida and the National Cancer Institute, in Bethesda, Maryland demonstrate that a subset of bacteriophages, dubbed “superspreaders,” potentially play a major role in transmitting antimicrobial resistance. The research, describe... Read More
Michael Doyle, PhD, Regents Professor of Food Microbiology at the University of Georgia's College of Agricultural and Environmental Sciences, discusses a variety of alternative food preservatives which can prevent unintended contamination of foods by pathogens and spoilage microbes.
ASM’s vir... Read More
Jonna Mazet, PhD, UC Davis School of Veterinary Medicine, is interviewed by Vincent Racaniello, PhD, Columbia University, New York, about emerging pathogen surveillance and public health. Dr. Mazet is the Principal Investigator and Global Director of the novel viral emergence early warning proje... Read More
Ian Goodfellow, PhD, Cambridge University, is interviewed by Vincent Racaniello, PhD, Columbia University, New York, about state of lab capacity in Africa during the Ebola outbreak. Goodfellow made the decision to go to Sierra Leone during the late summer of 2014 after following the media covera... Read More
Trudy joins the the TWiVlords to discuss new tests for detecting prions in the blood, and evidence showing that foamy retroviruses originated in the seas with their jawed vertebrate hosts at least 450 million years ago.
Hosts: Read More
Many mBiosphere readers will know that the influenza A virus infects multiple species, and this ability to infect birds, humans, and other mammals such as pigs is one of the ways virions can exchange genetic information, leading to new viruses able to cause major outbreaks. However, few mBiosphe... Read More

It was a peer review request that got Alessia Ruggieri and her group at University of Heidelberg to look more closely at how Dengue virus manipulates the cellular translation and stress machineries during infection.
In a previous study, Ruggieri showed that Hepatitis C virus infection induced... Read More
This episode: Microbes with complementary abilities help each other grow and produce useful stuff from the air!

"What is the best way to test for Trichomonas vaginalis in a cost effective manner? It's a classic trade-off between money and assay sensitivity." Read More
The TWiV academia discuss induction of diarrhea by the capsid protein of an astrovirus, and association of a fungal RNA virus with white-nose syndrome of North American bats.
Food microbiology is an important issue we cover on this blog, because food safety is vital to prevent foodborne illness. The use of technologies like whole-genome sequencing help identify and pinpoint the source of microbial contaminants, but how do microbes become contaminants in the first pla... Read More
If you are lucky enough to be still alive and working in 2050... How might the clinical microbiology laboratory have changed by that time? Nobody can accurately predict the future, but here are my personal thoughts... Read More
The hamlet of Resolute Bay is a tiny Arctic village in the Nunavut territory of Canada with a population that hovers at or below 300. Over hundreds of perhaps even thousands of years, the traditional Inuit diet in Resolute Bay and elsewhere has been dictated by the Arctic environment. The diet i... Read More
