Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More
Vincent, Michael, and Michele explain how the gut microbiome modulates colon tumorigenesis, and regulation of intestinal macrophage function by the microbial metabolite butyrate.
How long does it take to become a microbiologist?
I'd never heard of magnetotactic bacteria before and thought perhaps you guys might find this interesting. Not sure if you've mentioned these on TWIM before,... Read More
A new study from Karolinska Institutet in Sweden finds that testing for human papilloma virus (HPV) allows for longer time between screening tests when compared to cytology-based testing. The study is published in the scientific journal British Medical Journal (BMJ).
Cervical screening progra... Read More
In a move to reduce health care associated infections, certain attire for health care professionals, including the traditional white coat, could become a thing of the past.
"White coats, neckties, and wrist watches can become contaminated and may potentially serve as vehicles to carry germs f... Read More
In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it “could do little harm and might provide a touch of home, in addition to a spot of hunting.”
By the end of the century, the rabbits had begun to overrun native ecosystems, reaching ... Read More
New research finds significantly higher levels of infectious pathogens in water from faucet taps with aerators compared to water from deeper in the plumbing system. Contaminated water poses an increased risk for infection in immunocompromised patients. The study was published in the February iss... Read More
Going barefoot in parts of Africa, Asia, and South America contributes to hookworm infections, which afflict an estimated 700 million of the world’s poor. The parasitic worm lives in the soil and enters the body through the feet. By feeding on victims’ blood, the worms cause anemia and, in child... Read More
A new biosensor quickly detects salmonella in food and can be easily customized to detect other types of bacteria—or even different strains for the same bacterium.
The process appears to easily outperform tests that are now standard in the food industry, according to researchers at Rice Unive... Read More
An international team of researchers has made important progress in understanding the distribution of the deadly amphibian chytrid pathogen. In some regions, the deadly impact of the pathogen appears to be hampered by small predators, naturally occurring in freshwater bodies. These micropredator... 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
Research on bacterial movement tends to focus on the rod-shaped bacteria. With the aid of small waving flagella, each bacterial cell can push itself in the direction it wishes to go. They can also move in groups, forming large swarms that ripple and slide their way across Petri dishes. Spherical... Read More
A viral pathogen that typically infects plants has been found in honeybees and could help explain their decline. Researchers working in the U.S. and Beijing, China report their findings in mBio, the online open-access journal of the American Society for Microbiology.
The routine screening of ... Read More
This episode: Fungi herd and raise bacteria for slaughter!
(13.2 MB, 14.4 minutes)
Gram-negative bacteria pose a particular challenge to any enterprising phage. First the phage is met by the outer membrane (OM)—a barrier to surmount that also can be used as a convenient handgrip for adsorption. Next hazard is the nuclease-infested periplasm with its jungle of peptidoglycan. An... Read More
Viruses inspire many different types of art, but I was unaware of the number of people who make viruses out of fiber! Keep reading for some photographs of what I have found. Read More
In this blog entry, I explore how students can use their creativity to learn microbiology in innovative and often artistic ways. It makes learning more personal! Read More
Hello dear TWIM'ers!
Firstly I would like to apologize in advance for my poor English skills since my native language is Portuguese. This past few years much has been the attention towards drug resistant bacteria. I am aware that a couple of your podcast touched this subject, but a few weeks ... Read More
The novel avian H7N9 influenza virus has caused more than 130 human infections with 43 deaths in China. New research, conducted under the supervision of Kansas State University's Juergen Richt, is showing promise in helping to fight this deadly virus.
"Emergence of a novel drug-resistant H7N9... Read More
