Colonies of Alcaligenes

Circular, smooth, entire, opaque colonies of Alcaligenes on a nutrient agar plate. Taken from the Wistreich Collection, appearing exclusively on MicrobeWorld. Read More

Worm sperm motility

Two worm sperm shimmy across a microscope slide. Unlike most cells that rely on motor proteins to propel themselves forward, worm sperm use tiny fibers at their front ends. Putting the fibers together and taking them apart sets the cells in motion. In a new advance, researchers disassembled the ... Read More

"Never Really Alone" with Seth Bordenstein (Including Current News!)

This blog post describes a "video meeting" between Seth Bordenstein and my freshman writing class in the Fall of 2014. My freshman class revolved around ideas in symbioses and parasitism, so Seth's ideas regarding holobionts and the hologenome were particularly apt. Furthermore, last week Seth... Read More

Neoscytalidium dimidiatum arthrospore

It is a well recognized uncommon cause of skin and nail infection of the hands and feet . Unlike Dermatophytosis these mould infections are not contagious. There are few reports of invasive infection caused by N. dimidiatum; most infections occurred in immunocompromised hosts. Arthrospores are ... Read More

It takes a village... to ward off dangerous infections? New microbiome research suggests so

ANN ARBOR, Mich. -- Like a collection of ragtag villagers fighting off an invading army, the mix of bacteria that live in our guts may band together to keep dangerous infections from taking hold, new research suggests. Read More

Treponema pallidum

New resource makes gene-editing technology even more user friendly

Researchers at Harvard University and the University of California, San Diego, have developed a new user-friendly resource to accompany the powerful gene editing tool called CRISPR/Cas9, which has been widely adopted to make precise, targeted changes in DNA. This breakthrough has the potential t... Read More

Ice Nucleation Bacteria, Twitter, and Me!

In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More

New method to treat antibiotic resistant MRSA: Bacteriophages

MRSA is bad news. If you've never heard of it, here's what you need to know: It's pronounced MER-suh, it's a nasty bacterial infection and it can cause serious disease and death. Read More

Vaccination on the horizon for severe viral infection of the brain

Researchers from the University of Zurich and the University Hospital Zurich reveal possible new treatment methods for a rare, usually fatal brain disease. Thanks to their discovery that specific antibodies play a key role in combating the viral infection, a vaccine against the disease "progress... Read More

Stanford researchers genetically engineer yeast to produce opioids

For thousands of years, people have used yeast to ferment wine, brew beer and leaven bread. Now researchers at Stanford have genetically engineered yeast to make painkilling medicines, a breakthrough that heralds a faster and potentially less expensive way to produce many different types of pla...

Fungus on toilet seat (clearer view)

microbes in the environment: there are about 4 to 5 different colonies of bacteria which is growing in agar plate; sample from library toilet seat. (front view) Read More

A Spotter's Guide to Human Viruses

The New Scientist has published a nifty gallery of "psychedelic"-like images of human viruses. Many of them are from Government agencies so they are public domain. Click "source" to view the entire collection.

GUT TRANSIT TIME CHANGES WITH ‘TRAVELER’S DIET’

To better understand the importance of gut bacteria in human health, researchers measured the time it takes food to move through the gastrointestinal tract, called gut motility, in mice—in a way that mimics the dietary effects of world travel. Read More

Mold mycelium

A contaminant (mold mycelium) on a Serratia streak plate. Taken from the Wistreich Collection, appearing exclusively on MicrobeWorld. Read More

Detecting HIV diagnostic antibodies with DNA nanomachines

New research may revolutionize the slow, cumbersome and expensive process of detecting the antibodies that can help with the diagnosis of infectious and auto-immune diseases such as rheumatoid arthritis and HIV. An international team of researchers have designed and synthetized a nanometer-scale... Read More

Tiny Ocean Microbes are Brightening Up the Sky

Phytoplankton may be microscopic, but that doesn’t mean we can’t see them. Just look up: These little critters are brightening up cloudy days around the world. Read More
