Why use fluorescence microscopy for bacillus anthracis?
Perhaps fluorescence would be used because B. athracis has a cell wall making it difficult to visualize the details of the cytoplasm by simple bright field microscopy. Flourescence allows for labeling of specific entities, and "cold" illunimation of those entities against a dark field.
The ordinary light microscope is called a bright-field microscope because?
the object appears light on a dark background
What is a dark-field microscope used for?
Darkfield microscopes are useful in analyzing unstained tissue samples. Darkfield microscopy has also been used in computer mice, to help optical mice work on glass. It is also useful in the study of crystals and their defects.
What are conditions for a bright and a dark fringe?
central maximum is double the with of any other fringe. all other fringes(dark and bright) are of the same width.
Will the central ring be bright or dark?
It's bright during most of the show ... although they do dim it somewhat during the trapeze lady ... and then it's dark after the audience is gone.
What kind of technology does bright field dark field and phase microscopes use?
microscopy
What type of microscopy is the negative stain similar to?
The darkfield microscope. "darkfield microscopy"
What is Dark field microscopy?
Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.

How is spirochete activity seen?
observation with dark-field microscopy .

What is darkfield microscopy?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'

How is diagnosis for yaws conducted?
using a technique called dark-field microscopy. This often allows the spirochetes to be identified. They may also be identified in fluid withdrawn from swollen lymph nodes
The ordinary light microscope is called a bright-field microscope because?
the object appears light on a dark background
Gram stain of lymes disease?
Lyme Disease is caused by Borrelia burgdorferi. This is a spirochete bacterium with a gram negative cell wall structure. These organisms are best viewed by dark-field microscopy.
