The use of a commonly prescribed antibiotic is a major contributor to the spread of infection in hospitals by the ‘superbug’ MRSA, according to new research. The study also found that increasing measures to prevent infection – such as improved hygiene and hand washing – appeared to have only a s... Read More
Nearly one third of forestry workers in parts of eastern France are infected with Hepatitis E virus (HEV), according to a paper in the September Journal of Clinical Microbiology. Wild boars in the same region are also heavily infected. HEV is endemic in developing nations, but heretofore, HEV in... Read More
I comment a bit, as an educator, about the loss of Carl Woese. Not only the importance of his discoveries, but how he went about his work, remains of great value. Read More
Aunque el género Mycobacterium es asociado a infecciones tales como la lepra y la tuberculosis, hay un gran número de especies que son por lo general no patogénicos o patógenos oportunistas. En el episodio de hoy tenemos al Dr. Ricardo Santos del Instituto Superior Técnico de Lisboa, Portugal... Read More
Lately, we've been learning more and more about the teeming masses of bacteria inside our bodies - essentially trillions of tiny organisms that make us sick and keep us healthy.
Now two scientists at the University of Colorado have dared to ask what kinds of bacteria lives inside our mouths. ... Read More
Many species exhibit cooperative survival strategies — for example, sharing food or alerting other individuals when a predator is nearby. However, there are almost always freeloaders in the population who will take advantage of cooperators. This can be seen even among microbes such as yeast, whe... Read More
This episode: Some bacteria in the guts of healthy volunteers are able to break down gluten!

A new study of giant viruses supports the idea that viruses are ancient living organisms and not inanimate molecular remnants run amok, as some scientists have argued. The study may reshape the universal family tree, adding a fourth major branch to the three that most scientists agree represent ... 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
This episode: Antibiotic-degrading probiotics protect mouse gut microbes from hostile pathogen takeover after antibiotic treatment!

Sugary drinks help bad microbes grow in the human gut, according to a study published in the journal Obesity Reviews. This increase leads to many health complications like obesity and metabolic syndrome, raising risk of diseases associated with metabolic syndrome like diabetes.
The study says... Read More
Your most recent TWIV in Nebraska made me want to add a few verses to that old kids’ song…

In case this didn’t make the news in the city, I thought you might be interested in this report of Hantavirus in the Adirondacks. It looks like a wooden lean-to was the “scene of the crime” again!
A paper recently published in the Journal of Animal Science helps researchers further understand how microbials and probiotics affect poultry health.
Researchers at the North Carolina State University and Chung Jen College of Nursing, Health Sciences and Management (Taiwan) conducted a study ... Read More
