Viruses are prokaryotic microbes.

In the capsule stain, the capsule takes up the stain and will be dark in color.

Match the bacterial description to the staining procedure that allows a person to observe the feature described.

Match the subunit to the class of organic molecule where it is found.

A patient has a respiratory infection. The chest X-ray indicates the presences of granulomas in the lungs, suggesting tuberculosis. A sputum sample is collected to confirm that the patient has tuberculosis. Tuberculosis is caused by Mycobacterium tuberculosis, a species of bacteria that contain mycolic acid in its cell wall. What staining procedure will allow you determine if M. tuberculosis is present in the respiratory system?

You are observing a prepared slide of bacteria. The slide label says, “Bacteria, methylene blue.” When you observe the bacteria on the slide, you see blue helical cells. What type of staining process was used to prepare this slide?

Cryptococcus neoformans is a microbe that can cause meningitis. Infection occurs through inhalation of spores. If individuals with a compromised immune system inhale spores, the microbe can divide and lead to inflammation of the meninges surrounding the brain and spinal cord. In addition to reproducing through spores, C. neoformans cells have a nucleus, membrane-bound organelles, and a cell wall composed of chitin. What type of microbe is C. neoformans?

You are working as a nurse and have two patients suffering from pneumonia. Both patients are being treated with steroids and anti-inflammatory medications. The first patient has bacterial pneumonia and is also being treated with antibiotics. The second patient has viral pneumonia and is not receiving additional medications. Compare and contrast the two different microbial classes causing pneumonia in these patients.

Which class of microbes does not have mitochondria?

Mycoplasma species of bacteria are unique among the bacteria because they lack a cell wall. Like other bacteria and eukaryotic cells, Mycoplasma species have a cell membrane composed of phospholipids, and embedded proteins. In addition, the phospholipids, Mycoplasma contains steroids embedded in the cell membrane to provide additional stabilization, similar to animal cells. Compare and contrast the lipid components seen in Mycoplasma.
