Community-acquired Streptococcus Viridans Pneumonia in a Healthy Child.

ABSTRACT

Streptococcus viridans is usually considered to be nonpathogenic in healthy patients. Some strains become penicillin-resistant and cause life-threatening infections in immunocompromised patients. We report an immunocompetent boy who had community-acquired S. viridans pneumonia that was resistant to penicillin. Clinicians should note local patterns of virulence and antibiotic resistance in S. viridans and adjust treatment strategies accordingly.
