A new research report published in the July 2015 issue of the Jour... 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

Dear Vincent, Dickson and Daniel,
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
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
Microbes collected from Northern California and throughout the nation will soon blast into orbit for research and a microgravity growth competition on the International Space Station (ISS). This citizen science project, known as Project MERCCURI, is led by UC Davis microbiologists, who are inves... 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
