Bitter tasting yogurt or cheese may not make it to your refrigerator, but it is produced and the result of pesky bacteria. The microbial composition of raw milk impacts the quality, shelf life, and safety of processed milk and other dairy products. Controlling the quality of these products is tr... Read More
Insight into the biology of rhinovirus C from cryo-electron microscopy, and a novel antibiotic from a commensal bacterium that grows in the human nose, from the doctors of TWiM.
The previous post mentioned the onset of antibiotic resistance as one of the scarier, if less sensationalist, outbreaks of our time. We generally discuss antibiotic resistance in medically relevant microbes (on this blog and in the news), where resistance means the ability of disease-causing mic... Read More
Vincent speaks with David Tuller about flaws in the U.K's $8 million PACE trial for chronic fatigue syndrome, and efforts to have the trial data released.

One of the most dangerous places for an infection to occur is in the bloodstream. Septicemia, when microbes are present in the blood, not only allows bacteria access to other internal organs through the highway of our circulatory system, but also can cause a massive inflammatory response, leadin...

Amidst the fear surrounding Zika virus, remember that there are over 100,000 children born each year with birth defects caused by infection with rubella virus.
Rubella virus is a member of the Togaviridae family, which also includes chikungunya virus. The genome is a 9.7 kilobase, positive st... Read More
From ASV 2016 at Virginia Tech, Vincent, Rich and Kathy speak with Stephen Russell about his career and his work on oncolytic virotherapy - using viruses to treat cancers.

The molecular order of events is important in virulence, and a new paper published in the Journal of Bacteriology looks at the order of events necessary for bacterial toxin delivery to a host cell. Specifically, the authors looked at the assembly of Shiga toxin, produced by Shigella dysenteriae ... Read More
If it looks like a duck and quacks like a duck, it’s likely a duck – so goes the saying that illustrates the simplest explanation is usually the right one. But what about duck decoys used in conjunction with bird calls? Misidentification can be a deadly error – and the same goes for microbes. Mi... Read More
Methicillin Resistant Staphylococcus aureus (MRSA) isolated from animals. The organism was grown on seven different agar medium. On blood agar (Centre), it forms small to medium sized colonies surrounded by weak beta-hemolysis. It shows diverse types of color in different chromogenic medium- pin... Read More
How does a single-celled organism ‘know’ how to respond to its environmental conditions? Understanding microbial cell signaling is one way to determine how bacteria will react in a particular setting. In the past decade, researchers have revealed a significant role for cyclic-di-GMP in bacterial... Read More
I'm a graduate student working in mycoplasmology and I must say I've been overjoyed to hear the past few episodes mention our tiny friends!
Elio's mention of their unique mechanism of moving ("Gliding Motility") made... Read More
Because of its safety, efficacy, and affordability, chloroquine remains the treatment of choice for all Plasmodium species, except in regions with chloroquine-resistant P. falciparum. Chloroquine-resistant protists are treated with combination therapy, which includes artemisinin-derived molecule... Read More
The rapid spread of Zika virus through the Americas, together with the association of infection with microcephaly and Guillain-Barré syndrome, have propelled this previously ignored virus into the limelight. What is this virus and where did it come from?
One of the important tasks of Public Health England’s Mycology Reference Laboratory is to identify any newly emerging fungal pathogens that could become a public health risk. In recent months, the lab had tracked several clusters of Candida auris infections in British hospitals. The multidrug-re... Read More
Host: Jeff Fox with special guests, Gemma Reguera and Geoffrey Gadd.
Gemma Reguera of Michigan State University in East Lansing and Geoffrey Gadd of the University of Dundee in Scotland talk with Jeff Fox about their efforts, to probe some of the electrical properties of materials pro... Read More

It has been speculated that the development of neurological disease and fetal abnormalities after Zika virus infection may be due to the presence of antibodies against other flaviruses that enhance disease. In support of this hypothesis, it has been shown that antibodies to dengue virus enhance... Read More
