Basic Microbiology.

Microbiology is the study of microscopic organisms (microbes), which are defined as any living organism that is either a single cell (unicellular), a cell cluster, or has no cells at all (acellular). This includes eukaryotes, such as fungi and protists, and prokaryotes

9. What is an infection?

10. How is an infection diagnosed? Signs and symptoms When the body detects an infection, the immune system reacts to fight it. Signs and symptoms of an infection depend on the pathogen. The following list of symptoms are indications that the body is fighting an infection: Fever Pain Redness Swelling Fluid Drainage

11. Laboratory Diagnosis

12. What is a Gram Stain Test? In a Gram stain test, a sample is placed on a slide and dyed with chemicals. Depending on how the bacteria reacts to the stain, the test can determine whether the bacteria is Gram-positive or Gram-negative. The Gram stain takes less than an hour to perform. The result of this test can help clinicians quickly decide which antibiotic to choose.

13. A Gram-Positive Result indicates that the bacteria has a very thick outer layer (cell wall) with additional proteins (peptidoglycan). Gram-positive cells appear purple under the microscope. Examples of Gram-positive bacteria are Staphylococcus, Enterococcus and Streptococcus.

14. A Gram-Negative Stain Means that the bacteria does not have an extra layer in the cell wall. Gram-negative cells appear pink under the microscope. Examples of Gram-negative bacteria are E coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and the Acinetobacter species.
