This is as portrait of the late Francis Crick created by my wife Dr. Jennifer Quinn using "paint" of luminous bacteria. Photobacterium leignothi was grown in LB amended to 20g/l NaCl for a few hours until visible luminescence was detected visually. The liquid culture was painted onto amended L... Read More
BLOOMINGTON, Ind. -- Health experts have warned for years that the overuse of antibiotics is creating "superbugs" able to resist drugs treating infection. Read More
Scientific experiments with the herpesvirus such as the one that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of ...

As my Fall semester approaches, I am reflecting on last Fall. I taught a freshman seminar course revolving around symbioses and parasitism, and was fortunate to have many well known scientists be willing to "virtually visit" my class! Here is my report from last year on the great Jack Gilbert.... Read More
This slideshow outlines the work of WHOI scientists Tracy Mincer and Kristen Whalen in the quest to beat antibiotic resistance through bioprospecting in the ocean. Read More
MIT-WHOI Graduate student Kristen Hunter-Cevera describes the challenges and obstacles involved with growing marine microbes (in her case, Synechococcus) in a laboratory setting, and outlines the value of her research in understanding marine biogeochemistry. Read More
Immune cells that hang around after parasitic skin infection help ward off secondary attack, according to a study in The Journal of Experimental Medicine. These skin squatters may prove to be the key to successful anti-parasite vaccines. Read More
Scientists uncover a port of liver entry for malaria parasites in a report published in The Journal of Experimental Medicine. If these results hold up in humans, drugs that target this entry protein might help prevent the spread of disease. Read More
Inspired by the current Agar Art Contest and the gorgeous red of a recently isolated Serratia, I thought I'd try out my first bacteria "sketch." Using Serratia, Citrobacter, and an E. coli on Hektoen Agar I whipped up this goey DNA double helix! Read More
Scientists have engineered yeast cells that can “talk” to one another using a versatile plant hormone called auxin.
Typically, these simple fungal cells (Saccharomyces cerevisiae) usually do their jobs—making bread rise or converting sugar into alcohol—without having to communicate or work to... Read More
West Nile virus (WNV) is particularly dangerous in older people, who account for a large number of severe cases and deaths caused by the virus. WNV infection turns serious when the virus crosses the blood-brain-barrier and wreaks havoc among nerve cells in the brain. A study published on July 23... Read More
Serratia marcescens, Chromobacterium violeceum and Pseudomonas aeruginosa - what a romantic combination on Mueller Hinton II agar. All 3 organisms exhibit different pigment, Red, Purple and Green respectively on MHII agar, makes our daily routine of interpreting disk diffusion more interesting. Read More
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
This cutely radish photo of the colony of Aspergillus niger was taken by a digital camera. Before that Aspergillus niger was grown on SDA (Saboraud Dextrose Agar) media for the research purpose of testing antifungal activity of Scallop Powder(SP). SP ,a natural source obtained from Bivalves, can... Read More
Delftia acidovorans (formerly Comamonas acidovorans) is an aerobic gram-negative rod. It is unique because produces an orange color in the medium with the addition of Kovac's indole because of the production of anthranilic acid from typtone, though the organism is biochemically indole-negative. ...

Sometimes when a hairy beast of a contaminant grows on an old plate, the only thing to do is marvel at its beautiful rings and turn it into a cute cartoon. Any takers on the likely identity of this fungus? Read More
This is a photo of Bacillus subtilis sporulation on Phase contrast microscope. I take the photo by Canon camera! I love the photo this is a first time I have a good image on Phase contrast microscope.
I think, we should dilute the sample before carrying out the template.
Use the lame side, put... Read More
A new drug acts as a roadblock for malaria, curing mice of established infection, according to a study in The Journal of Experimental Medicine. Treatment was not associated with obvious side effects, suggesting that the drug may also be safe and effective in humans. Read More
Barbara Hinney and her colleagues from the Institute for Parasitology at the University of Veterinary Medicine, Vienna, screened 298 faecal samples taken from cats across Austria for single-cell intestinal parasites, so called enteric protozoa. The samples came from private households, catteries... Read More
