George Mason University researchers can find out if a tick bite means Lyme disease well before the bite victim begins to show symptoms.
"If you are bit by a tick, you can't be sure if you will get Lyme disease ― that is the biggest problem right now," says Alessandra Luchini, research assista... Read More
Pfizer Inc.’s Zithromax or a generic version of the antibiotic pill should be added to the standard treatment for gonorrhea to fight multidrug-resistant strains of the sexually transmitted bacterium, doctors in Europe said.
New European guidelines for sexually transmitted infections recommend... Read More
Bacteria talk to each other using N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signals. This signaling allows the bacteria to control gene expression of virulence factors and biofilms once a critical density has been achieved. This phenomenon, quorum sensing, is important when an infe... Read More

Eight years ago, Herbert Smith (not his real name) did the unthinkable -- he swallowed thousands of microscopic pig whipworm eggs in a desperate try to quell his advancing Crohn's disease.
"There was nothing to it," said Smith, a 33-year old financial analyst from New York. "It was drinking h... Read More
Hi All - I am getting to the part of my Micro class where I have students analyze antibiograms and noticed a blog pointing to the attached paper. Forgive me if this topic (antibiogram... Read More
Genetic exchange of antibiotic resistance occurs about 10 million times more effectively in the nose than in the blood of animals, report researchers.
Antibiotic resistance results from bacteria’s uncanny ability to morph and adapt, outwitting pharmaceuticals that are supposed to kill them. B... Read More
There are lots of things I enjoy about studying bacteria. I love their biochemistry and the secret inner workings of their metabolic pathways. I love that everything they do they manage within the confines of a single cell, and I love that you can go into a bacterial cell fairly easily and just ... Read More
Great TWIV 197, it is really nice to learn how science was. Fascinating to see how laborious was to do things that nowadays are only "kitology".
Keep up the great podcast.

HIV is an exceptional adversary. It is more diverse than any other virus, and it attacks the very immune cells that are meant to destroy it. If that wasn’t bad enough, it also has a stealth mode. The virus can smuggle its genes into those of long-lived white blood cells, and lie dormant for year... Read More
The Gram stain is commonly used in epidemiologic and clinical studies. It involves smearing a sample onto a slide, staining the material using dyes that bind to bacterial cells, and visually inspecting under a microscope. Many epidemiologic and clinical studies of pregnancy, sexually transmitted... Read More
