Penicillin-insensitive pneumococci. Case report and review.

G A Ahronheim, B Reich, M I Marks

    American Journal of Diseases of Children (1960)
    |February 1, 1979
    PubMed
    Summary

    Routine penicillin susceptibility testing is crucial for pneumococcal infections. Penicillin may be inadequate for central nervous system infections and long-term prophylaxis in asplenic patients due to increasing resistance.

    Area of Science:

    • Microbiology
    • Infectious Diseases
    • Clinical Medicine

    Background:

    • Infections caused by Streptococcus pneumoniae (pneumococci) with reduced penicillin susceptibility are increasingly recognized.
    • Understanding pneumococcal resistance patterns is vital for effective treatment strategies.

    Observation:

    • Infections caused by pneumococci with decreased penicillin susceptibility are infrequently reported.
    • Clinical experience suggests a need for reassessment of penicillin's role in treating certain pneumococcal infections.

    Findings:

    • Penicillin susceptibility testing for significant pneumococcal isolates should be standardized.
    • Penicillin may be insufficient for treating central nervous system (CNS) infections caused by pneumococci with a minimal inhibitory concentration (MIC) > 0.1 microgram/ml.
    • Long-term penicillin prophylaxis might be unsuitable for asplenic individuals in regions with prevalent resistant pneumococci.

    Implications:

    • This highlights the importance of updated clinical guidelines for pneumococcal infection management.
    • Clinicians should consider alternative antibiotics for CNS infections and prophylaxis in at-risk populations.
    • Enhanced surveillance of pneumococcal penicillin resistance is necessary to guide public health interventions.
