Each year, Streptococcus pneumoniae  — a bacterium — is a significant cause of morbidity and mortality in the U.S. despite the availability of a vaccine. Until 2000, at least 40% of the 60,000 cases of invasive S. pneumoniae infection were resistant to at least one drug. Pathogenic bacteria share the instinct to survive with their unwilling hosts. When faced with an antimicrobial attack, they rapidly assemble defensive resources. Although bacteria carry only a single chromosome, evolution has provided them with mechanisms that allow them to survive even aggressive antimicrobial treatment. Surviving bacteria are often resistant; these survivors reproduce and, by natural selection, become the dominant organism in the host. This course provides information about infections, antibiotic resistance, colonization and breaking the chain of disease.


The goal of this continuing education module is to broaden and update nurses’and respiratory therapists’ (RTs) knowledge of infectious disease causation and prevention. After studying the information presented here, you will be able to:
  • Identify the three components common to all infectious disease
  • List six of the factors associated with the emergence or resurgence and transmission of disease and one control measure for each
  • Identify three organisms associated with nosocomial disease
