Organisms grown in Fluid Thioglycollate Media w/out resazurin dye is a reducing media that uses sodium thioglycollate to chemically combine with dissolved oxygen to deplete the oxygen in the media. All organism except for Neisseria sicca were grown for 48 hours at 37 degrees C. Neisseria sicca i... Read More
Recording together for the first time, the TWiV team celebrates their 300th recording at the American Society for Microbiology headquarters in Washington, DC, where Vincent speaks with Dickson, Alan, Rich, and Kathy about their careers in science.

A sample of Proteus mirabilis was inoculated on to a TSA plate by taking a sterile swab and placing a drop in the center of the plate. The plate was then incubated at 37 degrees for 8 hrs. Swarming motility can be seen as a clear halo and finger like projections coming from and around the grow... Read More
Slime production by Staphylococcus epidermidis on Congo Red agar; demonstrated by black colored colonies. Slime production is one of the most important virulence factors produced by Coagulase negative Staphylococci.
The colonies of slime non-producing strains remain pink to red.

A bill to track drug-resistant infections has been introduced in Florida, inspired in part by FRONTLINE’s Hunting the Nightmare Bacteria.
The bill, sponsored by Rep. Janet Adkins, a Republican, requires the state health department to maintain an online record of the type and location of any a... Read More
esearchers from Harvard-affiliated Brigham and Women’s Hospital (BWH) and Harvard Medical School (HMS) have estimated that around 1 million children contract tuberculosis (TB) annually — twice the number previously thought to have the disease and three times the number of cases diagnosed every y...

I came across this paper and thought it sounded interesting for a discussion on TWiP:
Colonisation resistance in the sand fly gut: Leishmania protects Lutzomyia longipalpis from bacterial infection
Food-poisoning outbreaks linked to disease-causing strains of the bacterium Escherichia coli are normally associated with tainted meat products. However, between 20-30% of these are caused by people eating contaminated vegetables, as was seen in the 2011 outbreak in Europe that caused 53 deaths.... Read More
Like ecosystems the world over, the human microbiome is losing its diversity, to the potential detriment of the health of those it inhabits.
Dr. Martin J. Blaser, a specialist in infectious diseases at the New York University School of Medicine and the director of the Human Microbiome Program... Read More
A protein called GRP78 could be a universal therapeutic target for treating human diseases like brain cancer, Ebola, Influenza, Hepatitis and superbug bacteria such as MRSE and MRSA, according to a Virginia Commonwealth University-led pre-clinical study published this month in the Journal of Cel...

A team of clinician researchers has discovered a highly virulent, multidrug resistant form of the pathogen, Pseudomonas aeruginosa, in patient samples in Ohio. Their investigation suggests that the particular genetic element involved, which is still rare in the United States, has been spreading ... Read More
A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

Doctors are reporting a second instance of a baby born with AIDS going into remission, or possibly cured, by aggressive treatment after birth. The first case, a child from Mississippi who is now 3 1/2, was reported last April. Doctors revealed the case Wednesday at an AIDS conference in Boston. ... Read More
Scientists have known for years that together, bacteria and plants can remediate contaminated sites. Ramakrishna Wusirika, of Michigan Technological University, has determined that how you add bacteria to the mix can make a big difference. Wusirika has also shed light on the biochemical pathways...

Researchers have developed a high-tech method to rid the body of infections — even those caused by unknown pathogens. A device inspired by the spleen can quickly clean blood of everything from Escherichia coli to Ebola, researchers report on September 14 in Nature Medicine.
Blood infections c... Read More
A controversy that has been brewing for several years in the world of influenza research may ignite again with the publication last week of a new paper that’s worth a read. I haven’t to date written about the controversy, which centers on what’s called “gain of function” research. In the case of... Read More
