PCR Typing of Trichophyton Rubrum Isolates by Specific Amplification of Subrepeat Elements in Ribosomal DNA Nontranscribed Spacer
Background: Trichophyton rubrum (T. rubrum) is the most common cause of dermatophytosis of skin and nail tissue. Strain identification in Trichophyton rubrum is important for identification of strain-related differences in infectivity potential or transmissibility and epidemiological studies. PCR typing could determine whether the original isolate is responsible for re-infection or a new strain...
متن کاملGenotyping of Different Pestiviruse Isolates by RT-PCR
1320 blood samples were collected from herds showing clinical signs of pestiviral infections. 39 samples were positive in Ag-ELISA assay. All these 39 samples in addition to 5 cytopathic strains were cultured in MD-BK cell line and presence of pestiviral antigens was confirmed by direct-immunofluorescent test. 27 out of 44 BVDV suspected isolates were detected by RT-PCR using a primer set. Diff...
متن کامل[ABO genotyping by PCR-direct sequencing method].
OBJECTIVE To analyze the sequence difference between human A, B, and O alleles and establish the method of ABO genotyping by PCR direct sequencing. METHODS PCR-direct sequencing technique was used to analyze two regions of cDNA from A transferase gene, 233-433 and 660-788. RESULTS Two nucleotide substitutions at 258th and 297th were found in 233-433 region, and a nucleotide substitution at ...
متن کاملSerotyping, ribotyping, PCR-mediated ribosomal 16S-23S spacer analysis and arbitrarily primed PCR for epidemiological studies on Legionella pneumophila.
Fifty clinical and environmental isolates of Legionella pneumophila were typed serologically and by DNA fingerprinting using arbitrarily primed polymerase chain reaction (AP-PCR). Furthermore, variability in and around ribosomal operons was assessed by conventional ribotyping and PCR-mediated amplification of the spacer region separating the 16S and 23S genes. It appears that serotyping suffers...
متن کاملPCR-based sensitive detection of medicinal fungi Hericium species from ribosomal internal transcribed spacer (ITS) sequences.
Based on phylogenetic analysis of rDNA internal transcribed spacer (ITS) sequences, a pair of specific primers were designed for differentiating the Chinese traditional medicine Hericium species from other mushrooms by PCR. PCR was performed, with total DNAs as a template at an annealing temperature of 52-57 degrees C. Positive amplification was obtained from H. erinaceus with all DNA templates...
