A positive D test indicates that the presence of macrolide-inducible resistance to clindamycin produced by an inducible methylase enzyme that alters the common ribosomal binding site for macrolides, clindamycin and the group B streptogrammins (quinupristin). This cross-resistance, called the ML... Read More
Athens, Ga. - People feeding white ibises at public parks are turning the normally independent birds into beggars, and now researchers at the University of Georgia say it might also be helping spread disease. Read More
Sammy Salmonella was created on a Muller Hinton Agar using three different isolates of Pseudomonas aeruginosa and Staphylococcus aureus for the outline. Pseudomonas aeruginosa is the only species of Pseudomonas that will produce pyocyanin, which is what creates Sammy’s green color. These bacte... Read More
I am a Dutch PhD student working on Red Fluorescent Proteins and I really want to join the Agar Art Contest, but I just heard of it today!
I know the deadline was the 3th of September, but I still send you my artwork. Hope you enjoy it! Read More
The slide was prepared from blood of infected animals (cattle). The smear was stained with poly-chrome methylene blue which demonstrated blue colored bacillary body and light pink colored capsule (McFadyean's reaction).
The animal had the symptoms of high fever, convulsion and sudden death. ... Read More
Researchers at the University of Toronto examined fungi in the mucus of patients with cystic fibrosis and discovered how one particularly cunning fungal species has evolved to defend itself against neighbouring bacteria. Read More

Our sensitivity instruments rarely ever go down, but when they do our lab uses Kirby-Bauer testing to perform antimicrobial susceptibility testing in our laboratory. This testing involves placing antibiotic-infused discs on a standardized inoculum of bacteria spread in a lawn onto a Mueller Hint... Read More
This picture is taken in microbiology laboratory where i am doing job. I just found out this bacterial colony from water testing plates that was incubated at 30-35°C. But i am unable to identify this bacteria on basis of colony morphology and biochemical charecterstics. The colour of the bacte... Read More
An international study led by University of Queensland (UQ) researchers has tracked the re-emergence of a childhood disease which had largely disappeared over the past 100 years. Read More
We took a few swabs around school - a few cultures have grown up that I am unable to identify. The first is this orange culture, which came from our water fountains (photo is 3 days after the sample was taken). 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. ...

Yeast extract-mannitol agar (YMA), with the pH indicator bromothymol blue (BTB), is the medium used for rhizobia isolation and characterization.
In this pic, one Bradyrhizobium strain isolated from cowpea root nodule in Brazil showing a "white pearly colony" Read More
Streak plate of Proteus vulgaris. The plate was incubated at 37 degree C for 48 hrs then held at room temperature for 1 week. Swarming, white growth with finger like projections at the outer edges, around the circular solated colonies, circular white/beige opaque colonies, was not seen until ... Read More
Scientists at the Center for Infectious Disease Research recently uncovered a critical piece in the puzzle of how malaria parasites infect their host. The work, recently published in Science Magazine, reveals the details of how the malaria parasite invades its initial target organ, the liver. Wi... Read More

Isolate: Chromobacterium violaceum
Agar: Mueller Hinton Agar
Incubation Conditions: 24 hours at 37C + 24 hours at Room Temperature
Pictured is Chromobacterium violaceum shaped in a biohazard symbol. This drawing was done at a mic... Read More
DURHAM, N.C. - A unique molecule developed at Duke Medicine, the University of North Carolina at Chapel Hill and MacroGenics, Inc., is able to bind HIV-infected cells to the immune system's killer T cells. It could become a key part of a shock-and-kill strategy being developed in the hope of one... Read More
What if a single vaccine could protect people from infection by many different viruses? That concept is a step closer to reality. Read More
Bacillus cereus, a food-borne pathogen, is capable to form biofilms. Biofilms are microbial communities that are controlled by a biological mechanism called quorum sensing. In this image, the B. cereus biofilm was viewed under microscope using LPO and grown in microtiter plate well for 48 hrs of... Read More
