PE Question: LS2-1 Worth 5 pts

a. How do people use the idea of viral replication to argue that viruses are not alive?

CCC: Cause and Effect:

You have been told to obtain mucus from a patient's lung and to perform microbiological staining in order to determine the identity of the pathogen causing a patient’s illness.

You first perform a Gram stain, but upon microscopic analysis you visualize a mixture of pink bacilli and purple cocci.

Explain the results you have just observed and discuss what you may now do in order to identify the pathogen.

For full credit: Include the 5 I's and the process of using selective and differential media to help you determine the potential pathogens

Bacterial vs Eukaryotic Diseases

Bacterial and eukaryotic diseases are two different types of infections that affect the human body. Bacterial diseases are caused by bacteria, which are single-celled organisms that can reproduce and multiply on their own. Some common bacterial diseases include strep throat, tuberculosis, and urinary tract infections. On the other hand, eukaryotic diseases are caused by organisms that have a defined nucleus, such as fungi, parasites, and certain types of protists. Examples of eukaryotic diseases include athlete's foot, malaria, and giardiasis. While both types of diseases can have similar symptoms, such as fever and fatigue, they require different treatment approaches. Bacterial diseases are often treated with antibiotics, which target and kill the bacteria. Eukaryotic diseases, on the other hand, may be treated with antifungal medications, antiparasitic drugs, or other specific treatments depending on the type of infection. Understanding the differences between bacterial and eukaryotic diseases is important for effective diagnosis and treatment.
