Treatment of sewage to reduce water contamination
Destruction of vectors by spraying insecticides
Destruction of an animal reservoir of the infectious agent
All of the choices are used to reduce o eliminate the source of an infection
Bacterial cell walls have a unique structure not found in eukaryotic host cells
Bacterial cell wall synthesis is easily inhibited wheras eukaryotic cell wall synthesis is more resistant to the action of the drugs
Euk cells do not take up the drugs
Euk cells inactivate the drugs before they can do any damage

Viral metabolism resembles that of their hosts so there is no selective point of attack
Viruses use the metabolic machinery of their hosts which limits many of the potential points of attack
Viruses have no metabolism and therefore offer no selective point of attack
Actually, viruses are not difficult to treat with chemotherapeutic agents
The amount of drug administered
The route of administration and speed of uptake
The rate at which the drug is cleared or eliminated from the body
All of the above
A disease that maintains a steady low level frequency
When a disease occurs occasionally and at erratic intervals in the human population
A sudden increase in the occurrence of a disease above the expected level
A sudden unexpected occurrence of a disease in a limited segment of a population

Cell-mediated
Antibody-mediated
Innate acquired
Innate natural
Humoral
The discovery of factors essential to disease occurrence
The development of methods for disease prevention
Measuring the level of resistance to antimicrobial agents
Both the discovery of factors essential to disease occurrence and the development of methods for disease prevention
Both the discovery of factors essential to disease occurrence and measuring the level of resistance to antimicrobial agents
