Question

1. Why are yeast infections a common type of superinfection that results from long-term use of broad spectrum antimicrobials?

2. Too often patients will stop taking antimicrobial drugs before the prescription is finished. What are factors that cause a patient to stop too soon, and what negative impacts could this have?

3. How does the biology of HIV necessitate the need to treat HIV infections with multiple drugs?

Answer 1

Question

1. The yeast infection are common type of superinfection that result from long-term use of broad-spectrum  antibiotics because these antibiotics also target many normal microbiota that live in the body and increases the immunity of the body. Therefore, killing of normal microbioata favor the growth of yeast infection mainly because their activity are inhibited by those normal microbioata.

2. The factors that cause a patient to stop soon are:

I. Patient unawareness about the complete course of antibiotics.

II. Long duration of taking antibiotics.

III. Side-effects of antibiotics.

IV. Not so good taste of antibiotics.

The negative affect of not completing the course of antibiotic is that it increases the risk of " multiple -drug resistance". The microbe become resiatant to the antibiotic and therefore it increases the chances that disease require other drug to treat.

3. HIV attack the CD4 cells of the host and therefore decreses the immunity of the host. Also, the HIV virus is RNA virus, it means it have RNA as a genetic material. Therefore, it use host DNA to make their genetic material that is RNA.
