Molecular phylogeny and genetic diversity in all the nine species (Rhizophora mucronata, R. apiculata, R. stylosa, Bruguira cylindrical, B. parviflora, B. gymnorriza, Ceriops tagal and C. decandra) and a natural Rhizophora hybrid, of the mangrove Rhizophoraceae, occurring in the Indian sub-continent were analysed using random amplified polymorphic DNA (RAPD), restriction fragment length polymor...

Two hundred seventeen isolates of Borrelia burgdorferi originally cultured from skin biopsy samples or blood of early Lyme disease patients were genetically characterized by PCR-restriction fragment length polymorphism (RFLP) typing of the 16S-23S ribosomal DNA intergenic spacer. Three major RFLP types were observed. Of the cultured isolates, 63 of 217 (29.0%) were type 1, 85 of 217 (39.2%) wer...

objective(s):the utilization of molecular techniques in the epidemiology of tuberculosis have provided an opportunity for using effective markers to trace the transmission of the disease .the purpose of this study was to compare the genetic patterns of mycobacterium tuberculosis by three methods of rflp technique. materials and methods: in a cross-sectional and prospective study, 95 strains of ...

Our aim was to analyze the difference between methods for genotyping of Mycobacterium tuberculosis complex isolates. We collected genotyping results from Restriction Fragment Length Polymorphism (RFLP) and Mycobacterial Interspersed Repetitive Units-Variable Numbers of Tandem Repeat (MIRU-VNTR) in a geographically limited area (Stockholm) during a period of three years. The number and proportio...

BACKGROUND Due to the differences in the oncogenic activity of human papillomaviruses (HPV), it is clinically important to accurately identify HPV types in a simple and time effective manner. OBJECTIVES We aimed at developing a straightforward and cost-effective assay to individually identify all mucosal HPVs, based on the amplification of L1 gene using MY09/11 primers, and subsequent restric...

Restriction fragment length polymorphism (RFLP) analysis with probes derived from the insertion element IS6110, the direct repeat sequence, and the polymorphic GC-rich sequence (PGRS) and a PCR-based typing method called spacer oligonucleotide typing (spoligotyping) were used to strain type Mycobacterium bovis isolates from the Republic of Ireland. Results were assessed for 452 isolates which w...

AIM To develop polymerase chain reaction based artificial restriction fragment length polymorphism (artificial RFLP PCR) assays for DR3 and DR4 alleles of the multiallelic DRB1 locus and to apply them to paraffin wax embedded archival material. METHODS Sixty five samples from DRB1 typed cell lines were analysed using the artificial RFLP PCR method to determine the specificity and sensitivity ...

We compared genotyping by restriction fragment length polymorphism (RFLP) analysis of the amplified omp1 gene with serotyping by dot enzyme-linked immunosorbent assay (dot-ELISA) to determine the suitability of RFLP analysis for epidemiologic study. Fifteen prototypes of Chlamydia trachomatis and 30 clinical isolates were used in this study. To serotype with dot-ELISA, chlamydia antigen was spo...

Fusarium proliferatum is a well-known plant pathogenic fungus-infected many crops. The present study was carried out to molecularly identified and characterized morphologically F. from various hosts substrates. species identity of the isolates verified as based on TEF-1α sequences phylogenetic analysis indicated high intraspecific variations. RFLP-IGS also variations which were clustered into t...

Phytoplasmas are dangerous bacteria severely infecting agricultural production worldwide. In the present study, identification of phytoplasmas tomato plants showing symptoms such as small leaves, flower abnormalities, stunting, witches' broom, and reddening was performed. Five plants, two symptomatic three asymptomatic, were tested to verify phytoplasma infection. Total DNA isolated from 5 leaf...
