This episode: Bacteria that swarm in the soil cooperate or compete based on one particular protein structure!
(10.5 MB, 11.5 minutes)
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

Vincent and Dickson discuss how malaria parasites induce odors in their rodent hosts that attract mosquitoes.
Four months ago, a mucus sample arrived in Dr. Ali Mohamed Zaki’s laboratory in Saudi Arabia.
The mucus had been coughed up by a 60-year-old Saudi Arabian man with a strange case of pneumonia. He had been admitted to the Dr. Soliman Fakeeh hospital in Jeddah on June 13; soon after, his kidney... Read More
Researchers from the Univ. of Rochester and Texas A&M Univ. have found that, over a period of five months following the disastrous 2010 Deepwater Horizon explosion and oil spill, naturally occurring bacteria that exist in the Gulf of Mexico consumed and removed at least 200,000 tons of oil and ...

Vincent and Dickson welcome new TWiP host Daniel Griffin to discuss the association of a new Mycoplasma with trichomoniasis, and to introduce a new feature to the show, a case study.
In a study that's already being greeted with notes of caution, Danish researchers report that children whose mothers had the flu or ran a fever lasting more than a week during pregnancy had an increased risk of developing an autism spectrum disorder.
U.S. health officials stress that the new ... Read More
A new study by researchers at Imperial College London has identified a way in which Salmonella bacteria, which cause gastroenteritis and typhoid fever, counteract the defence mechanisms of human cells.
One way in which our cells fight off infections is by engulfing the smaller bacterial cell... Read More
Study shows that key proteins in mucus prevent bacterial adhesion to surfaces, could help prevent growth of biofilms.
Slimy layers of bacterial growth, known as biofilms, pose a significant hazard in industrial and medical settings. Once established, biofilms are very difficult to remove, and... Read More
