Direct detection of Brucella spp. in raw milk by PCR and reverse hybridization with 16S-23S rRNA spacer probes.
The 16S-23S rRNA spacer regions of Brucella abortus, B. melitensis, and B. suis were cloned and subcloned after PCR amplification. Sequence analysis of the inserts revealed a spacer of about 800 bp with very high ( > 99%) homology among the three species examined. Two genus-specific primer pairs, BRU-P5-BRU-P8 and BRU-P6-BRU-P7, that could be used in a nested PCR format and three genus-specific...
متن کاملDirect real-time PCR-based detection of Neisseria gonorrhoeae 23S rRNA mutations associated with azithromycin resistance.
OBJECTIVES Surveillance for Neisseria gonorrhoeae azithromycin resistance is of growing importance given increasing use of ceftriaxone and azithromycin dual therapy for gonorrhoea treatment. In this study, we developed two real-time PCR methods for direct detection of two key N. gonorrhoeae 23S rRNA mutations associated with azithromycin resistance. METHODS The real-time PCR assays, 2611-PCR ...
متن کاملMonitoring a widespread bacterial group: in situ detection of planctomycetes with 16S rRNA-targeted probes.
The group of planctomycetes represents a separate line of descent within the domain Bacteria. Two phylum-specific 16S rRNA-targeted oligonucleotide probes for planctomycetes have been designed, optimized for in situ hybridization and used in different habitats to detect members of the group in situ. The probes, named PLA46 and PLA886, are targeting all or nearly all members of the planctomycete...
متن کاملUse of 16S rRNA gene-targeted group-specific primers for real-time PCR analysis of predominant bacteria in human feces.
16S rRNA gene-targeted group-specific primers were designed and validated for specific detection and quantification of the Clostridium leptum subgroup and the Atopobium cluster. To monitor the predominant bacteria in human feces by real-time PCR, we used these specific primers together with four sets of group-specific primers for the Clostridium coccoides group, the Bacteroides fragilis group, ...
متن کاملprobeBase: an online resource for rRNA-targeted oligonucleotide probes
Ribosomal RNA-(rRNA)-targeted oligonucleotide probes are widely used for culture-independent identification of microorganisms in environmental and clinical samples. ProbeBase is a comprehensive database containing more than 700 published rRNA-targeted oligonucleotide probe sequences (status August 2002) with supporting bibliographic and biological annotation that can be accessed through the int...
