Washington, DC – July 11, 2016 – A team of Italian investigators has discovered a new variant of an emerging antibiotic resistance mechanism. The new variant, dubbed mcr-1.2, confers resistance to colistin, a last-resort antibiotic against multidrug-resistant Gram-negative pathogens. The researc... Read More

Bacterial mats, golden brown in color, seen at the outer edges of a geothermal vent/geyser. Cyanobacteria grow around 163 F or lower. Yellowstone National Park.
Floor swab was done for a science project. One of the organisms seen was mucoid, opaque in color and had finger like projections (swarming) after growth on TSA at 37 degree's C for 48 hrs. Read More
Serratia marcescensgrown on TSA for 48 hrs. at 37 degree's C then held at room temp for 24 hrs. Serratia marcescens is circular, mucoid and has a red to oragne pigment due to the production of prodigiosin. Usually the red coloration dose best at reduced temperatures so after initial grown at ... Read More

Colony collapse disorder (CCD) has caused such a profound drop in honeybee populations that even the U.S. Congress is addressing the issue: Senator Jeff Merkley (D-Oregon) has proposed the Pollinator Recovery Act to preserve pollinator habitat. The rapid decline in these important pollinators af... Read More
Our work on Zika virus has utilized two different antibodies to detect Zika virus replication within cells. I described one antibody, directed against double-stranded RNA (dsRNA) in a previous article. A second antibody directed against a Zika virus protein has also been useful...

Marine plastic debris is a growing concern that has captured the general public’s attention. While the negative impacts of plastic debris on oceanic macrobiota, including mammals and birds, are well documented, little is known about its influence on smaller marine residents, including microbes t...

A central pursuit of microbial ecology is to accurately model changes in microbial community composition in response to environmental factors. This goal requires a thorough understanding of the drivers of variability in microbial populations. However, most microbial ecology studies focus on the ... Read More
BUFFALO, N.Y. - Most people recoil at the thought of ingesting E. coli. But what if the headline-grabbing bacteria could be used to fight disease? Read More
CAMBRIDGE, MA -- MIT engineers have developed a new type of easily customizable vaccine that can be manufactured in one week, allowing it to be rapidly deployed in response to disease outbreaks. So far, they have designed vaccines against Ebola, H1N1 influenza, and Toxoplasma gondii (a relative ... Read More
The application of polymer matrix composites has found valuable in many engineering fields like electrical, marine, aerospace, electronics and microelectronics. Thus, a new technique like microwave through electromagnetic energy was explored for processing of polymer matrix composite Read More
Imitation may be the sincerest form of flattery, but it can also be the easiest way to make a buck. That’s the primary motivation for camouflaging within an already-established brand: Sunbucks, McDowell’s, and Mountain Lightening all rely on brand recognition – of a brand that isn’t their own. W...

Mold culture growing on top of a home made yogurt culture. Yogurt was made using whole milk and incubated for 8 hrs at a ~30 degree's C then refrigerated. This culture had been in the refrigerator for over 2 weeks, well past expiration for home made yogurt. The green mold had spore formation ... Read More

This week's Microbial Science Friday article on the ASM blog is a celebration of the 100-year anniversary of the National Park System. It takes place in the world's first national park, Yellowstone--where some of the most exotic and colorful microbial communities live. #NPS100 Read More
Although the Gram-negative bacterium Vibrio cholerae (right) is normally associated with human pathogenic disease, most V. cholerae cells spend their lives in an aquatic environment, and only a few of the many serotypes are able to cause disease. When strains acquire the right genetic makeup – s... Read More
