Abstract
A Canadian adult with bacteremic pneumonia caused by a relatively penicillin-resistant (minimal inhibitory concentration 0.25 μg/mL) Streptococcus pneumoniae is reported, and the published literature regarding penicillin-resistant pneumococci in Canada reviewed. Although penicillin resistance has been reported infrequently to date, this case emphasizes the need for routine antimicrobial sensitivity testing of all pneumococci isolated from normally sterile sites, and for ongoing systematic surveillance for penicillin and other antibiotic resistance in Canada.
Highlights
Penicillin-resistant pneumococci h ave been infrequently reported from Canada
MICROBIOLOGICAL METHODS AND RESULTS Blood culture isolates of Strep pneumoniae were identified according to standard me t11ods
Since . resistant stra ins have been reported from m any countries. a nd in som e a reas t11e prevalence of penicillin-resistant pneumococci is extremely high
Summary
When a pn eumococcus that was re latively resistant to penicillin was first reported from Australia (1). Penicillin-resistant pneumococci h ave been infrequently reported from Canada. British Columbia who developed bacteremic pneumococcal pneumonia witl[1] an isolate th at was relatively resistant (MIC 0.25 pg/mL). Two sets· of blood cultures drawn on admission to hospital grew Streptococcus pne wnoniae.
