Antimicrobial resistance in Streptococcus pneumoniae: an overview
1Department of Pathology, Hershey Medical Center, Pennsylvania 17033.
Summary
Penicillin resistance in Streptococcus pneumoniae is a growing global concern, first identified in 1965. This increasing antimicrobial resistance necessitates monitoring and targeted interventions worldwide.
Area of Science:
- Microbiology
- Infectious Diseases
- Antimicrobial Resistance
Background:
- Penicillin resistance in Streptococcus pneumoniae (pneumococcus) was first documented in 1965.
- Since then, resistance has been increasingly reported globally.
Observation:
- Penicillin-resistant strains have been isolated in South Africa, Spain, Hungary, Eastern Europe, France, the United States (especially Alaska and the South), Canada, Zambia, Japan, Malaysia, Pakistan, Bangladesh, Chile, and Brazil.
- Multidrug-resistant strains have also been identified in some regions.
Findings:
- The prevalence of penicillin-resistant pneumococci is rising worldwide.
- Geographic distribution of resistance is widespread, affecting numerous countries across continents.
Implications:
- The increasing prevalence of resistant strains mandates selective susceptibility testing.
- Epidemiological investigations are crucial for managing outbreaks of resistant pneumococci.
