Saccharomyces cerevisiae is a species of yeast. It is the active agent responsible for our most basic foods - bread, wine, and beer since ancient civilizations. It has been long since humans have tried to understand how to make them more productive. However, it was not until the Genomic Era that... Read More
B. cereus was grown on urea agar for 6 days at 37 degrees C to induce spore formation.
The endospore stain was done using malachite green as the primary stain and safranin as counter the stain. Malachite green was applied to the smear and set over a steaming water bath for 10 min (stain was no... Read More

If the laboratory is not able to identify group-B streptococci (GBS) by the Lancefield grouping procedure, there are other microbiologic tests that can be used to identify GBS. This picture shows one of these tests. It is called the CAMP test. CAMP is an acronym for the authors of this test (Chr... Read More
