Bacteria live everywhere, from the surface of your skin to the bottom of the sea; there are more bacteria on earth than there are people, and bacteria can be both a pleasure and a nuisance to live with and work with. Bacteriologists rely on microscopes to carry out their work, and today, with many advances in the field of microbiology, the digital high power microscope can help bacteriologists understand bacteria even better.
Before bacteria can be examined, they have to be cultured in the laboratory. This is done in order for the bacteria to multiply to high concentration, which can allow scientists to study them better with or without a microscope. This is because different bacteria form different sizes, colors, and shapes of colonies in culture, and this can further aid scientists in identifying them. It is routine in bacteriology to use data from both microscopy and culture in order to identify and classify bacterial species.
There are two ways to culture bacteria in the laboratory. They can be spread onto a solid medium, such as nutrient agar. This can allow bacteria to form colonies that can allow them to be identified, but this can be cumbersome for bacteriologists as solid culture media are harder to take cells from without risk of contaminating the entire culture plate. Bacteria can also be cultured using liquid media: once bacteria start colonizing the nutrient liquid medium, the medium becomes cloudy and blurry. A few drops of this culture medium can be directly transferred onto a slide, and the bacteria can be examined under the microscope. However, bacteria can only be identified, in this case, using their appearance under the microscope, and not their colony configuration. Bacteriologists usually make use of a combination of these two techniques in their experiments.
Bacteria are often invisible under the microscope, so scientists need to stain them in order to better see cellular structures. Some staining methods can also identify bacteria, or can classify them into different diagnostic categories. For instance, Gram staining divides most bacteria into two main categories depending on the contents and configuration of their cell wall. Gram positive bacteria appear purple under the microscope. Such bacteria have thick cell walls. On the other hand, Gram negative bacteria appear red or pink under the microscope. Gram negative bacteria have much thinner cell walls.
The classification of bacteria according to the Gram system is important in medicine. Some antibiotics will work only on Gram positive bacteria, while other antibiotics will work only on Gram negative bacteria. Antibiotics that are designated as broad spectrum will work for both types. This can make Gram staining, and hence, microscopy, important to medicine. Digital high power microscopes, in particular, give scientists, researchers, and medical technologists an edge, because it can give them a much clearer view of specimens. With poor lighting and magnification, purple and pink can look almost the same under the microscope, so digital high power microscopes are often used in laboratories, whether they are based in schools or in hospitals.
Medicine is not the only field that benefits from the use of digital high power microscopes. Industrial microbiology requires the use of specific kinds of bacteria that can lose function when contaminated with other bacteria in the same medium. Digital high power microscopes help industrial microbiologists monitor their cultures better and document their results. Veterinary microbiologists can make good use of such microscopes in diagnosis as well. Not only does this kind of microscopy allow veterinarians to see specimens better, it gives them a chance to present specimens in a format easily viewable by pet owners during a consultation, or other veterinarians during a conference.
A digital high power microscope can allow you to not only see bacteria better under the microscope, but take pictures of these bacteria as well. With the right illumination and staining methods, as well as with well-cultured bacteria, you can have fairly good images. You only need to clean the lenses of digital high power microscope regularly, since molds and mildew can cloud your lenses and make visualization difficult. You must keep in mind that the digital camera used in digital high power microscopy shares lenses with the digital high power microscope, so care must be taken to keep lenses in good working order.
