The U.S. Food and Drug Administration today allowed marketing in the U.S. of the first mass spectrometer system for automated identification of bacteria and yeasts that are known to cause serious illness in humans. The VITEK MS can identify 193 different microorganisms and can perform up to 192 ... Read More
The disruption of the human microbiome through use of antimicrobials is a topic of growing interest among healthcare epidemiologists, not only because it is a major risk factor for C. difficile infection (CDI), but also because it could be a driving force behind the introduction and proliferatio...

Trichomonas vaginalis is a protozoan parasite of the urogenital tract in men and women and causes a sexually transmitted disease, trichomoniasis, in about half of infected women. Infections are associated with pelvic inflammatory disease, adverse pregnancy outcomes, infertility, an increased inc... Read More
Florida health officials are encouraging the state’s residents not to be alarmed following another death from the flesh-eating bacteria Vibrio vulnificus. The rare bacteria that thrives in saltwater has killed 10 people in Florida this year, while 31 people in all have been infected with the ... Read More
Scientists at the University of Texas and the University of Iowa have created a synthetic bacteria that grows thanks to one of humankind's favorite stimulants — caffeine. According to a report from Quartz, this bacteria can be added to any caffeinated beverage and it'll grow according to the lev... Read More
Proteases are vital proteins that serve for order within cells. They break apart other proteins, ensuring that these are properly synthesized and decomposed. Proteases are also responsible for the pathogenic effects of many kinds of bacteria. Now chemists at the Technische Universitaet Muenchen ... Read More
Thanks to a rare bacteria that grows only on rocks in the Swiss Alps, researchers at The University of Texas at Austin and the Pasteur Institute in France have been the first to identify how alcohol might affect key brain proteins.
It’s a major step on the road to eventually developing drugs ... Read More
The search for a cure for deadly infectious disease like Tuberculosis has led a researcher for the US deep underwater.
Brian Murphy, assistant professor of medicinal chemistry and pharmacognosy at the University of Illinois at Chicago, is collecting actinomycete bacteria from water throughout... Read More
The most abundant photosynthetic organism in the world sheds countless little sacs into the oceans, which could be having a dramatic impact on marine ecosystems, according to a new study. These microbial buds contain proteins and genetic material, which may influence the growth of other marine m... Read More
Researchers use a protein-lipid complex found in human breast milk to increase the activity of otherwise-ineffective antibiotics against drug-resistant pathogens. A protein-lipid complex that naturally occurs in human breast milk can increase the sensitivity of methicillin-resistant Staphylococc... Read More
Geobacter's pili conduct electrons along their length using the rings on aromatic amino acids, according to a study in mBio this week. Contrary to all other known forms of biological electron transport, in which electrons are carried by discrete entities and passed from one to another, Geobacter... Read More
A new class of molecules called acyldepsipeptides—ADEPs—may provide a new way to attack bacteria that have developed resistance to antibiotics.
Researchers have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemica... Read More
In this blog post, I describe a simple "colony transformation" experiment I have done with my freshman students, illustrating transformation, antibiotic resistance, and GFP. The visual aspects help drive home the points effectivel. Read More
Our bodies are made up by cells containing our own DNA. Plus 10 times as many with foreign DNA. The bacteria found on our skin, and inside our organs (intestine, vagina, mouth, nose, etc.) are referred to as our “microbiome”, outnumber our own cells by 10 to 1, and make up a vital organ with ind...

Hello dear TWIM'ers!
Firstly I would like to apologize in advance for my poor English skills since my native language is Portuguese. This past few years much has been the attention towards drug resistant bacteria. I am aware that a couple of your podcast touched this subject, but a few weeks ... Read More
A tiny molecular machine used by bacteria to kill attacking viruses could change the way that scientists edit the DNA of plants, animals and fungi, revolutionizing genetic engineering. The protein, called Cas9, is quite simply a way to more accurately cut a piece of DNA.
“This could significa... Read More
From the shiny, strong nacre that gives abalone shells an unbreakable, opaline sheen, to the goopy mix of proteins fired by a velvet worm that solidify and trap prey upon impact, nature is packed with inspiration for scientists designing new materials.
Waterproof adhesives and self-cleaning s... Read More
