Helicobacter is a Gram-negative rod with a helical shape on gram stain. The most known strain is H. pylori, which causes ulcers and chronic gastritis and is said to affect up to 50% of the human population. This particular strain, Helicobacter fennelliae is most commonly found in the feces an... 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
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
Pictured here is Rhodotorula, a beautiful coral-colored yeast grown on Sabouraud's Dextrose Agar.
Rhodotorula species are common environmental contaminants, found naturally in air, water, soil, and other areas. This yeast rarely is a pathogen, though it can cause infections in immumocompromis... 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

Unknown Bacillus from handprint. Colony was large, almost half the plate, and exhibited rhizoid growth. Plate was grown at 37 degree C for 2 days then held at room temp for 3+ days. Read More
Sputum specimen from sick of fibrosis cystic can hold many microbes and yeast. This specimen sent to our laboratory Mycobacteriology of Polyclinic University of Messina for mycobacteria research, shows yeast cells with Ziehl-Neelsen stain. Read More
Unknown fungal isolated contaminant found on MAC. MAC plate was incubated for 2 months at 4 degrees C once fungal growth was seen. This colony seemed to emerge from the agar and had a 3D appearance. The center of the colony had what seemed to be hyphal growth while the edges had a hard waxy un... Read More
A group of fungi growing on the surface of stagnant black tea left open to the environment. I've found this leads to beautiful morphologies when I try it. 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
This picture was taken in early October 2014 in the Washington, DC metro area. The temperature that week had been in the mid-70's during the day to the low 60's at night (Fahrenheit), and it hadn't been too humid. This had grown at the base of a tree, and was very large -- my hand is in there fo... 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
