Identification of Aeromonas culicicola by 16S rDNA RFLP.
Studies were conducted on the improvement of A. culicicola identification. This species is phenotypically very similar to A. veronii biotype sobria, A. sobria, and A. allosaccharophila. The sequences of 16S rDNA of A. culicicola isolates show the highest similarity with A. jandaei, A. veronii, and A. caviae. Digestion of 16S rDNA PCR product with AluI and MboI restriction endonucleases allowed ...
متن کاملDifferentiation of group VIII Spiroplasma strains with sequences of the 16S-23S rDNA intergenic spacer region.
Spiroplasma species (Mollicutes: Spiroplasmataceae) are associated with a wide variety of insects, and serology has classified this genus into 34 groups, 3 with subgroups. The 16S rRNA gene has been used for phylogenetic analysis of spiroplasmas, but this approach is uninformative for group VIII because the serologically distinct subgroups generally have similarity coefficients >0.990. Therefor...
متن کاملMolecular Assessment of 16S-23S rDNA Internal Transcribed Spacer Length Polymorphism of Aeromonas hydrophila
Aeromonas hydrophila is an important bacterial pathogen which causes the hemorrhagic septicemia in fishes, amphibians and humans. Genetic relationships of diverse isolates of A. hydrophila were recovered from fish and water sources. These isolates were investigated by flanked region of 16S and 23S Ribosomal DNA (rDNA) internal transcribed spacer (ITS). Here we analyzed polymorphism of PCR-ampli...
متن کاملIdentification and Typing of Aeromonas Hydrophila through 16S rDNA-PCR Fingerprinting
Raghava et al. stated that the identification and classification of microorganisms are of fundamental importance in microbiology [2]. Classical methods are basically dependent on phenotypic data. These are also time consuming and expensive. Various fingerprinting methods can be broadly classified DNA fingerprinting by restriction enzyme analysis of the genomic DNA on pulse field gel electrophor...
متن کاملExtended method for discrimination of Aeromonas spp. by 16S rDNA RFLP analysis.
A previously described molecular method, based on 16S rDNA RFLP analysis, for the identification of Aeromonas spp. was unable to separate the species Aeromonas salmonicida, Aeromonas bestiarum and the recently described Aeromonas popoffii. In this study, the method has been extended with endonucleases AIwNI and PstI for the identification of these species. A molecular frame for the identificati...
