Student Thoughts On The First Day of Microbiology Class

I teach Microbiology at the University of Puget Sound every fall semester. The swiftly changing field of microbiology has depth and breath...and I was interested to learn what my students thought of the topic at the beginning of the first day of class. We will revisit this subject at the end o... Read More

Antibiotic stewardship - a community effort

As we highlighted in our previous blog, antibiotic stewardship – the careful use of appropriate antibiotic administration – can have positive effects. A small change from a difference in clinical lab reporting led to less drug use, which led to fewer drug-resistant infections. When we think of a... Read More

TWiV 402: The plight of the bumblebee

Polio returns to Nigeria, Zika virus spreads in Miami, and virus infection of plants attracts bumblebees for pollination, from the virus gentlepeople at TWiV.

Anti-bacterial fabric holds promise for fighting superbug

Antibiotics have proven to be a valuable weapon in the fight against infectious bacteria. However, due to the excess use of antibiotics in conventional treatments, overtime antibiotics have become less effective. Read More

People with rage disorder twice as likely to have latent toxoplasmosis parasite infection

Individuals with a psychiatric disorder involving recurrent bouts of extreme, impulsive anger--road rage, for example--are more than twice as likely to have been exposed to a common parasite than healthy individuals with no psychiatric diagnosis. Read More

A cultural revolution in the study of the gut microbiome

(BOSTON) - It's estimated that as many as 1,000,000 Americans suffer from inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn's disease, which cause mild to severe symptoms that at best can be managed and at worst can lead to life-threatening complications. While abnormal imm... Read More

Microbiology Myths Debunked: Scientific Analysis of the Five Second Rule

While walking through your house, you drop a granola bar you were eating. Quick – do you pick it up and eat it? Is the ground too dirty to eat from? Does the amount of time the food sits on the ground matter? Will more microbes gather onto the snack as you decide whether or not to continue noshi... Read More

Ancient clay remedy proves its antibacterial powers in the lab

Near Kisameet Bay on the central coast of British Columbia sits a deposit of clay that covers 5 acres and spans a depth up to 42 feet in places. This vast smear formed 10,000 years ago as glacial melt filled a granite basin and fine minerals silted out.

The ancient clay likely holds secrets t... Read More

Microbial Identification and Tracking: the Next Generation

How do you identify an unknown microbe? If you’ve taken an introductory microbiology lab course in the past twenty years, chances are you were assigned an unknown bacterium that you had to identify through differential media and biochemical assays. Newer techniques like qPCR are being standardiz... Read More

Moving to Zika Virus

I have worked on polio virus in my laboratory at Columbia University for 35 years. When that virus is eradicated--perhaps in the next few years--we will have to destroy all of our virus stocks. When that happens, I can either go home, or find another virus.

When Zika virus stepped into the w... Read More

The classic and current studies of bacterial endospore morphology

Recently, one of the Journal of Bacteriology Classic Spotlight series highlighted the numerous studies on bacterial spores that have been published in the journal throughout the years. Bacterial endospores, the resilient and relatively quiescent bacterial structures first identified in the 1800s... Read More

Study reveals how herpes virus tricks the immune system

With over half the U.S. population infected, most people are familiar with the pesky cold sore outbreaks caused by the herpes virus. The virus outsmarts the immune system by interfering with the process that normally allows immune cells to recognize and destroy foreign invaders. How exactly the ... Read More

The image of Red Lord Ganesha on this MacConkey agar plate is made of Serratia marcescens. It is just an expression that microorganisms are ubiquitous and miraculous in nature just as our gods.
Serratia marcescens produces a blood red pigment called prodigiosin (latin word prodigiosus meaning ... Read More

3-D protein map offers new malaria vaccine hope

A three-dimensional 'map' of a critical protein that malaria parasites use to invade human red blood cells could lead to a vaccine countering the most widespread species of the parasite. Read More

How Forest Loss Is Leading To a Rise in Human Disease

In Borneo, an island shared by Indonesia and Malaysia, some of the world’s oldest tropical forests are being cut down and replaced with oil palm plantations at a breakneck pace. Wiping forests high in biodiversity off the land for monoculture plantations causes numerous environmental problems, f... Read More

Immune system maintains a memory of past infections by priming genes for future encounters

Our ability to fight off recurrent infections, such as colds or flu, may lie in the 'immunological memory' found in a newly discovered class of gene regulatory elements, according to research from the University of Birmingham, supported by the BBSRC and Bloodwise. Read More

Enhanced virus transduction may lead to more effective gene therapy

A benefit of the voluminous wealth of research produced is that it allows us to stand on the shoulders of giants – we can take advantage of established facts, tools, and datasets. This may mean using a mutant library to find genes in your organism that are important for the process you study; ac... Read More

Motherboard: Your Showerhead Is Crammed Full of Bacteria That Scientists Want to Study

Scientists know very little about the kinds of bacteria that we interact with on a daily basis in our homes. Researchers from Colorado, and North Carolina are interested in what kinds of microbes are living in your shower head.

They are hoping to find out where Nontuberculous mycobacteria is... Read More
