The most likely explanation for seeing several perfect circles that are completely clear surrounding your specimen in a wet mount under a microscope is that air bubbles have formed in the mounting medium. These air bubbles can create a halo effect around the specimen, appearing as perfect circles. To resolve this issue, gently tapping the slide or using a fine needle to release the trapped air bubbles can help improve the clarity of the observation. Additionally, ensuring that the mounting medium is properly applied and the slide is prepared without any air pockets can prevent this phenomenon from occurring.

A scanning tunneling microscope can show detailed surface structures but the organism must be prepared by being plated with a very thin layer of metal. Most organisms can't survive this process. To see a three dimensional image of a living organism you should select a stereo microscope.
A Henrici slide is a specialized microscope slide used in microbiology to examine and identify fungi. It consists of a thin layer of agar on a glass slide, which allows fungi to be cultured and observed under the microscope. It is named after the Swiss mycologist, Hanns Hofmann Henrici.
Gram-positive and gram-negative refer to the Gram stain used to prepare slides of bacteria for viewing under a light microscope. Viruses are too small to see under a light microscope and have to be prepared differently for viewing under an electron microscope. So the answer to your question is neither
Yes
If your microscope is a Transmission Microscope then light has to pass through the specimen (that is how the microscope works).Other kinds of microscopes may not require this.
Samples for observation by an electron microscope are typically prepared by fixing the specimen in a chemical solution, dehydrating it, and then embedding it in a resin for stability. The sample is then sliced into ultrathin sections using a microtome before being stained to enhance contrast. Finally, the prepared sample is placed inside the electron microscope for imaging.

A compound microscope uses two or more glass lenses to magnify either living cells or prepared slides. This type of microscope is commonly used in laboratories and educational settings to study cells and microorganisms at a cellular level.
The milk is cultured, allowing colonies of bacteria to grow. The causative bacteria then can be specially prepared for identification under a microscope.
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.
A prepared slide for a compound light microscope is composed of a viewing sample suspended in a drop of distilled water, which has been placed on one glass slide. A second glass slide will be placed on the first slide and any residual water will be gently soaked up by a paper towel.

Samples from the skin lesions can be prepared with special stains, to allow identification of the causative bacteria under the microscope.
