One of the conundrums facing TB research is the fact that Mtb grows incredibly slowly. Slow growth confounds both research and treatment since it can take days to weeks to grow a culture for study, a month or more to determine drug resistance properties of a patient sample, and months of antibio...

The esteemed TWiVumvirate reveal the discovery of a new negative stranded RNA virus of wasps that regulates longevity and sex ratio of its parasitoid host.
Vincent, Elio, and Michael reveal what Neanderthals ate from analysis of DNA in their teeth, and new CRISPR-Cas systems found in the genomes of uncultured microbes.
Oh I hope I win!
Hi TWIM Team
We would like to know the experience when you work with your proteins (recombinant protein, native protein, lysate etc.), no matter it is success or failure. Did you get on well with the protein or still “fight” with it? Tell us your story. But, no, no, no, we don’t want to hear your presentatio... Read More
his was a swab taken form the bottom of a shoe incubated for 48 hrs at 37 degrees C then held at room temp for 48 hrs then held at refrigerated temp's. A variety of colony morphology is seen, rhizoid, mucoid, etc. Image taken using transmitted light. Read More
Robert Koch published the first photographs of individual bacteria in 1877, nearly 200 years after Antoni van Leeuwenhoek sent drawings of bacteria in a letter to the Royal Society. Long before cameras were linked with microscopes, generations of microscopists relied on their own eyes, pencil, a... Read More
The lovely TWiV team explore evolution of our fecal virome, and the antiviral RNA interference response in the nematode C. elegans.
While detection and reaction to light sources is a well-known process in environmental organisms exposed to diurnal light cycling, light detection also affects the biological processes of human pathogens. The human pathogen Acinetobacter baumannii, a microbe associated with hospital-acquired inf... Read More
Here is my chance to chat a bit with some University of Puget Sound staff about the depth, breadth, and wonders of the microbial world. It's a podcast! Read More
Scientists from the University of Liverpool’s Institute of Infection and Global Health have shown that phage therapy could offer a safe and effective alternative to antibiotics in the treatment of Cystic Fibrosis lung infections.
Chronic lung infections caused by the bacterium Pseudomonas aer... Read More
Researchers with the Iowa City VA Health Care System and University of Iowa have produced striking new evidence of neutrophil plasticity, or the ability of these white blood cells to change their properties.
The scientists exposed neutrophils—the most prevalent white blood cells—to Helicobact... Read More
A team of researchers from iMM Lisboa led by Luísa Figueiredo and in collaboration with Joe Takahashi's group from Southwestern University has shown for the first time that the parasite responsible for sleeping sickness, Trypanosoma brucei, has its own internal clock, which allows it to antecipa...

Frozen and freeze-dried products for Fecal Microbiota Transplantation (FMT) are nearly as effective as fresh product at treating patients with Clostridium difficile (C-diff) infection, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) School of Publi...

I was asked recently why Jacques Monod did not followup on his early work on bacterial growth. Instead, he happily veered in a different direction and went on to become one of the fathers of Molecular Biology. Together with François Jacob, he proposed the operon model and other key breakthr...

Be honest – do the cases in the lefthand table make you break into hives? It’s not an uncommon response! S. aureus is a sneaky bacterium, throwing susceptibility curve-balls like those to the left on a regular basis. Not to mention the non-aureus staphylococci, which we are now routinely identif...
