Microbiology Exam Questions Practice Test part 3

Microbiology is a branch of biology that focuses on the study of microorganisms, including bacteria, viruses, fungi, protozoa, and algae. Microorganisms are tiny living organisms that can only be seen with the aid of a microscope, and they are present in almost every environment on Earth. Microbiology seeks to understand the structure, function, and behavior of microorganisms, as well as their interactions with other organisms and their environments. The field includes a wide range of research topics, including the study of infectious diseases, microbial genetics, environmental microbiology, and the use of microorganisms in biotechnology and industry. Microbiologists use a variety of techniques to study microorganisms, including microscopy, DNA sequencing, and other molecular biology techniques. They may work in a variety of settings, including research labs, public health agencies, or in industries such as food and beverage production or pharmaceuticals. Overall, microbiology plays a critical role in many aspects of modern life, from understanding and treating infectious diseases to developing new medicines and technologies.

Studying bacterial shape, cell wall, size, …. & so on, need to scope the bacteria under a microscope. But you can not see any cells unless staining these cells, imagine that as a glass cup (cell) in front of whiteboard (microscope field), you cannot see this cup unless pouring a stain inside it. that is the same with bacterial staining and these cups (cell) differ in staining technique according to the aim of the study as simple stain, gram stain, spore stain, …. and so on.

About gram stain: depending on bacterial cell wall composition, the ability of bacteria to accept crystal violet with iodine to be gram-positive or not. Dividing bacteria into gram-positive or gram-negative is very important in bacterial taxonomy, also in determining the type of antibacterial treatment with diseases.

For spore stain: bacteria form spores as a preservation tool for life when exposed to environmental harsh conditions such as high temperature, radiation, acidity, salinity, drought, …., and so on. Also, spores are forming within a stationary phase during bacterial growth. So it is necessary to detect spore-forming bacteria in foods & dairy products to prevent spoilage through shelf life.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
