Identifying mutator phenotypes among fluoroquinolone-resistant strains of Streptococcus pneumoniae using fluctuation analysis.
Antimicrob. Agents Chemother. 51 , 3225-9, (2007) The occurrence of mutator phenotypes among laboratory-generated and clinical levofloxacin-resistant strains of Streptococcus pneumoniae was determined using fluctuation analysis. The in vitro selection for levofloxacin-resistant mutants of strain D39, each wi... |

Genotypic identification of presumptive Streptococcus pneumoniae by PCR using four genes highly specific for S. pneumoniae.
J. Med. Microbiol. 55(Pt 6) , 709-14, (2006) It was previously reported that two oligonucleotide primer sets (spn9802 and spn9828) for discriminating Streptococcus pneumoniae from pneumococcus-like oral streptococcal isolates using PCR had been developed. In this study, PCR amplification of the lytA, pl... |

Possible overestimation of penicillin resistant Streptococcus pneumoniae colonization rates due to misidentification of oropharyngeal streptococci.
Diagn. Microbiol. Infect. Dis. 42(4) , 263-8, (2002) Standard identification of Streptococcus pneumoniae by optochin and bile solubility testing can lead to ambiguous results for certain isolates. Newer bacteriologic identification techniques (e.g., DNA probes) now exist. In a prospective point prevalence study... |

Characterization of in vitro-generated and clinical optochin-resistant strains of Streptococcus pneumoniae isolated from Argentina.
J. Clin. Microbiol. 46(6) , 1930-4, (2008) Optochin susceptibility is a key test used for pneumococcal diagnosis, but optochin-resistant (Opt(r)) pneumococci have been reported in the last 2 decades. In this work, we characterized eight Opt(r) clinical strains which presented a new mutation, G47V, a p... |

Diversity of mutations in the atpC gene coding for the c Subunit of F0F1 ATPase in clinical isolates of optochin-resistant Streptococcus pneumoniae from Brazil.
J. Clin. Microbiol. 45(9) , 3065-7, (2007) We report the characteristics of four optochin-resistant (Opt(r)) Streptococcus pneumoniae isolates from Brazil. All four Opt(r) isolates presented mutations in the nucleotide sequence coding for the c subunit of F(0)F(1) ATPase. Two isolates showed mutations... |

Emergence of optochin resistance among Streptococcus pneumoniae in Portugal.
Microb. Drug Resist. 12(4) , 239-45, (2006) In most clinical microbiology laboratories optochin susceptibility is used in the screening and identification of Streptococcus pneumoniae. We report the characterization of 32 optochin-resistant S. pneumoniae strains from 10 laboratories that constituted 3.2... |

Phenotypic and genotypic discrepancy of Streptococcus pneumoniae strains isolated from Asian countries.
FEMS Immunol. Med. Microbiol. 45(1) , 63-70, (2005) Non-typeable isolates of Streptococcus pneumoniae collected from Asian countries were characterized by optochin susceptibility test, bile solubility test, multilocus sequence typing of housekeeping genes, amplification of virulence-related genes, 16S rDNA-Rsa... |

Optochin resistance in Streptococcus pneumoniae induced by frozen storage in glycerol.
Diagn. Microbiol. Infect. Dis. 58(2) , 185-90, (2007) Susceptibility to optochin is frequently the only test used to differentiate Streptococcus pneumoniae from other alpha-hemolytic streptococci isolated from clinical specimens. The current study shows that storage of S. pneumoniae isolates in tryptic soy broth... |

A novel mutation in the alpha-helix 1 of the C subunit of the F(1)/F(0) ATPase responsible for optochin resistance of a Streptococcus pneumoniae clinical isolate.
Diagn. Microbiol. Infect. Dis. 38(2) , 119-21, (2000) Previously reported mutations involved in optochin resistance of Streptococcus pneumoniae clinical isolates changed residues 48, 49 or 50, in the transmembrane alpha-helix 2 of the F(1)/F(0) ATPase subunit. We report here an unusual mutation which changes the... |
