An 'exhausted' army of immune cells may not be able to fight off infection, but if its soldiers fight too hard they risk damaging the very body they are meant to be protecting, suggests new research from the University of Cambridge. Read More
An antimicrobial agent found in common household soaps, shampoos and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection. Researchers at the University of Michigan report their fi... Read More
Recognizing the importance of the public health emergency of the Ebola outbreak in western Africa, the organizers of the Interscience Conference on Antimicrobial ... Read More
Hosts: Vincent Racaniello, Michele Swanson, and Michael Schmidt.
Vincent, Michael, and Michele reveal how a fungal protease blunts the innate immune response and promotes pathogenicity.
Dear TWIP Trifecta,
How are you? It is lovely here in lower Manhattan, 82 F / 27 C with blue skies and not much in the way of humidity to make things wilt.
Since you are all going on the road, I’ll be on the edge of my seat waiting t... Read More
Many parasites commandeer the bodies of their hosts in order to spread. Examples of this include horsehair worms that reach water by forcing their cricket hosts to drown themselves, and liver flukes that drive infected ants to climb blades of grass, where cows can eat the insects, and so the flu...

Many institutions, such as my own, only have one microbiology course. In this second "Mu-Tube" video, I ask my current junior and senior Microbiology students what *they* think first year students ought to know about #MattersMicrobial. I think their opinions are interesting, and will inform my... Read More
One of the first challenges is in properly diagnosing Zika infection. Diagnosis is challenging for several reasons: first, many infected individuals don’t suffer severe symptoms. Those that do have relatively non-specific symptoms of low-grade fever, headaches, and muscle soreness that are somet... Read More
Deep in the heart of the Ecuadorian Amazon lies one of the worst environmental disasters in human history. Over the past several decades, oil companies have discharged more than 18 billion gallons of petroleum contaminated wastewater into the Sucumbíos region in northeastern Ecuador. The contami...

Did you see this paper in PLoS Computational Biology? It's mind-blowing. U. Maryland researchers found evidence for Acinetobacter and Pseudomonas nucleic acid integrated into human chromosomes and mitochondria, po... Read More
Dear Vincent, Dickson and Daniel,
A fun little read about lichens and their impressive attributes, accompanied by some beautiful photographs. (If the use of the term "kingdom Monera" gives you cause to smirk, just ignore it and keep reading.) Read More
Streptomycetes are a member actinomycete family. Streptomycetes are usually found in soil and are important decomposers. They are aerobic, gram-positive, filamentous rods that create branching hyphae. They also produce more than half of the world's antibiotics, and are therefore very valuable in... Read More
For my medical microbiology course at Kutztown University of Pennsylvania we were asked to take a sample from our nose. Using a sterile cotton swab, a sample was taken from a nostril and then spread onto the Mannitol Salt Agar plate supplied. The plate was incubated at 37 degrees Celsius, then e... Read More

Important ingredients: 6.5% salt, dextrose, bromcresol purple
Differential/Selective: used to test for salt tolerance and can be used to identify enterococcal group D streptococci. NaCl is a selective agent and those organisms that can grow in higher salt concentrations also ferment the dextro... Read More
