E. coli was grown on MacConkey Agar (MAC) at 37 degrees for 24 hour. MAC is a Selective and Differential media used to inhibit G+ growth and some G- bacteria as well as identify and isolate lactose fermenting G- enteric bacteria mainly Enterobacteriaceae. Strong lactose fermentation produces pi... Read More

This tree is made up of Streptococus pneumoniae (as the leaves)and Candida albicans (as the trunk),cultured on a chocolate agar incubated 24hours under 5% CO2 condition.
S.pneumoniae is a alpha hemolytic organism producing green colour colonies while C.albicans produce 'feet'around the margin o... Read More
can u help me about this picture?
what's ur idea about this gram staining and arrangement?
in blood media alpha hemolysis has been seen so in macconkey agar have pink colony.

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
The picture was taken after my students at the Inter American University of Puerto Rico-San German, learned the technique of water filtration analysis of fecal coliforms in water. They filtrated a mL of groundwater from a nearby aquifer and transferred the filter to Endo agar plates. The pictur... Read More

E. coli growth on EMB Agar. EMB Agar slightly inhibits gram-positive bacteria due to the combination of dyes and is a selective and differential medium for coliforms. Bacteria that ferments lactose will exhibit a green metallic sheen. This image represents E. coli as a quality control microorga... Read More
