Epulopiscium fishelsoni is a Gram-positive bacteria found in the gut of a sturgeon fish. The largest ones found are up to 700μm in length. Your field of view when using the 100X objective has a diameter of 12mm. If you were to line up your Epulopiscium fishelsoni in a strepto- fashion, how many entire bacteria would fit in your field of view? Write just the number with any needed commas. Do not include units.
Microscopic examination
The analysis of minute organisms, cellular organization of any biological structure, and composition of body fluids with the help of a microscope is known as microscopic examination. The magnification of specimens or samples under study helps in attaining a clearer picture of it.
Gram Staining
Named after Hans Christian Gram, a Danish bacteriologist, Gram stain is one of the most powerful staining techniques within microbiology. This technique was introduced in 1882 to identify pneumonia-causing organisms. The Gram staining technique uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.
