Abstract
Over the past decade, antimicrobial resistance has emerged as a major public-health crisis. Common bacterial pathogens in the community such as Streptococcus pneumoniae have become progressively more resistant to traditional antibiotics. Salmonella strains are beginning to show resistance to crucial fluoroquinolone drugs. Community outbreaks caused by a resistant form of Staphylococcus aureus, known as community-associated meticillin (formerly methicillin)-resistant Staphylococcus aureus, have caused serious morbidity and even deaths in previously healthy children and adults. To decrease the spread of such antimicrobial-resistant pathogens in the community, a greater understanding of their means of emergence and survival is needed.

Glossary
- Minimum inhibitory concentration
-
The lowest concentration of an antibiotic that inhibits growth of the organism.
- Clonal dissemination
-
The spread of one or several clones of an organism throughout a region or population.
- Folliculitis
-
An infection of the skin localized to the hair follicles. Lesions are erythematous and sometimes pustular.
- Infective endocarditis
-
An infection of a heart valve that can lead to tissue destruction, valvular dysfunction, stroke and heart failure.
- Necrotizing pneumonia
-
A severe, often fulminant, infection of the lungs with tissue destruction caused both by the pathogen and by the response of the host immune system.
- Necrotizing fasciitis
-
A deep infection of subcutaneous tissue resulting in progressive destruction of the fascial and fat layers. It can spread rapidly and is associated with a high mortality if not treated early.
