Germaphobes, maybe you're on to something.
Sickness-causing bacteria and viruses can lurk on surfaces long after they're expelled in an infected person's sneeze or snot. Some can even stay on a surface for months, given the right conditions. While the ability of these microorganisms to actual... Read More
Streak plate isolation of E. coli on MacConkey Agar grown for 24 hrs at 37 degrees. E. coli demonstrates strong lactose fermentation indicated by the bright pink halo, bile precipitant around the colonies, and pink colony growth. Read More
TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host’s body.
These findings are report... Read More
The placenta is full of microbes, a new study finds, raising questions about how that ecosystem and mothers' oral health influence the risk of pre-term birth.
Even before a baby is born a microbial ecosystem takes up residence in the placenta, creating a microbiome that may help shape the new... Read More
Scientists for Science are confident that biomedical research on potentially dangerous pathogens can be performed safely and is essential for a comprehensive understanding of microbial disease pathogenesis, prevention and treatment. The results of such research are often unanticipated and accrue... Read More
To my great delight, I just discovered your podcasts twiv, twim and twip.
The first twip I heard, about Strongyloides stercoralis, although informative and interesting, seemed to have several inaccuracies. I w... Read More

Cystic fibrosis patients suffer from chronic bacterial infections and thick mucous in their lungs, due largely to a combination of microbial infections and resulting inflammation. A common pathogen, Pseudomonas aeruginosa, which can lay dormant in healthy individuals, becomes virulent in the lun... Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More
Bioengineer Ingmar Riedel-Kruse of Stanford University has created a series of games where players control organic microbes.
The games, which you can see showcased in the video below, places a collection of single-celled protozoans called paramecia in a thumbnail-sized chamber with electrode-... Read More
Many air travelers are concerned about the risks of catching a disease from other passengers given the long time spent in crowded air cabins. New research shows disease-causing bacteria can linger on surfaces commonly found in airplane cabins for days, even up to a week. Participants discuss ... Read More

A new class of molecules called acyldepsipeptides—ADEPs—may provide a new way to attack bacteria that have developed resistance to antibiotics.
Researchers have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemica... Read More
Later this month (May 2014) the World Health Assembly will decide whether to destroy the remaining stocks of variola virus – the agent of smallpox – or to allow continued research on the virus at WHO-approved laboratories. We are interested in your opinion on this issue. Please follow the link t... Read More
Vincent and Dickson discuss the spread of P. knowlesi in Malaysia, and how Leishmania parasites protect the sandfly gut from bacterial infection.
