Optochin resistance among Streptococcus pneumoniae strains colonizing healthy children in Portugal.

Journal of clinical microbiology - 1 Jan 2008

Nunes Sónia, Sá-Leão Raquel, de Lencastre Hermínia

Abstract excerpt

Two percent of 1,973 pneumococcus strains isolated from carriers since 2001 in Portugal were found to be optochin resistant. These strains belonged to eight serotypes (and some were nontypeable), and they had diverse genetic backgrounds. Novel optochin-resistant lineages were detected over time, suggesting that there was a continuous, although sporadic, emergence of optochin resistance.
