Estimating recombinational parameters in Streptococcus pneumoniae from multilocus sequence typing data.
Multilocus sequence typing (MLST) is a highly discriminatory molecular typing method that defines isolates of bacterial pathogens using the sequences of approximately 450-bp internal fragments of seven housekeeping genes. This technique has been applied to 575 isolates of Streptococcus pneumoniae and identifies a number of discrete clonal complexes. These clonal complexes are typically represen...
متن کاملMultilocus sequence typing of Cryptosporidium hominis from northern India
BACKGROUND & OBJECTIVES Human cryptosporidiosis is endemic worldwide, and at least eight species have been reported in humans; the most common being Cryptosporidium hominis and C. parvum. Detailed understanding of the epidemiology of Cryptosporidium is increasingly facilitated using standardized universal technique for species differentiation and subtyping. In this study micro- and minisatellit...
متن کاملMultilocus sequence typing of Streptococcus pneumoniae by use of mass spectrometry.
Multilocus sequence typing (MLST) is an important tool for the global surveillance of bacterial pathogens that is performed by comparing the sequences of designated housekeeping genes. We developed and tested a novel mass spectrometry-based method for MLST of Streptococcus pneumoniae. PCR amplicons were subjected to in vitro transcription and base-specific cleavage, followed by analysis of the ...
متن کاملMultilocus sequence typing of Klebsiella pneumoniae nosocomial isolates.
A multilocus sequence typing (MLST) scheme was developed for Klebsiella pneumoniae. Sequences of seven housekeeping genes were obtained for 67 K. pneumoniae strains, including 19 ceftazidime- and ciprofloxacin-resistant isolates. Forty distinct allelic profiles were identified. MLST data were validated against ribotyping and showed high (96%) discriminatory power. The MLST approach provides una...
متن کاملMultilocus sequence typing system for group B streptococcus.
A multilocus sequence typing (MLST) system was developed for group B streptococcus (GBS). The system was used to characterize a collection (n = 152) of globally and ecologically diverse human strains of GBS that included representatives of capsular serotypes Ia, Ib, II, III, V, VI, and VIII. Fragments (459 to 519 bp) of seven housekeeping genes were amplified by PCR for each strain and sequence...
