Serratia marcescens can form brilliant red colonies on LB agar due to the synthesis of the secondary metabolite prodigiosin. In the Microbiology teaching lab, we had students create pigment mutants of S. marcescens and these lovely shades of pink and white were collected for analysis. Read More
I am in need of some assistance in Identifying a bacteria species. I am unable to locate a match in Bergey's Manual. Our copy is 20 years out of date. I know the photo isnt great, it was taken with a cell phone. The colonies are hot pink and were cultured on TSA slant. It is gram + micrococci, i... Read More

Methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant superbug, can cause life-threatening skin, bloodstream and surgical site infections or pneumonia. Researchers at the University of California, San Diego School of Medicine now report that cigarette smoke may make matters... Read More
Streptomycetes are a member actinomycete family. Streptomycetes are usually found in soil and are important decomposers. They are aerobic, gram-positive, filamentous rods that create branching hyphae. They also produce more than half of the world's antibiotics, and are therefore very valuable in... Read More

A concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics, according to laboratory experiments.
The findings, which will appear in the journal Applied and Environmental Microbiology, suggest that combining maple syrup extract with common antibiotics ... Read More
A leukemia-like cancer is killing soft-shell clams along the east coast of North America. The cancer is transmitted between animals in the ocean, and appears to have originated in a single clam as recently as 40 years ago. Read More
It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of the bacterial immune system is to detect the difference between "foreign"... Read More
The multidrug-resistant, incredibly contagious Shigella has popped up in 32 US states in the past year. The bacteria infect your intestines and trigger crampy rectal pain, bloody or mucus-laced diarrhea and vomiting. What can you do? Vigilant hygiene. And if you do get sick, go for an over-the-c...

News that a stomach bug is becoming resistant to antibiotics is alarming, but before you start fearing the so-called new bug, there are a few things you should know.
The Centers for Disease Control and Prevention reported this week that the bacteria Shigella sonnei has become resistant to cip... Read More
Vincent, Dickson, and Daniel discuss how filarial infection modulates the immune response to mycobacterial infection, and reveal a new case study.
Researchers at the University of Michigan are studying the ecology of microbes in the GI tract in hopes of developing novel diagnostic tests and effective treatments for intestinal disease. How are they studying this? By creating tiny gut ecosystems! Using undifferentiated stem cells, the inv... Read More
