Once known some biological characteristics of six Trypanosoma cruzi strains, randomly amplified polymorphic DNA (RAPD) analysis was made. Cluster analysis by UPGMA (unweighted pair group method analysis) was then applied both to biological parameters and RAPD profiles. Inspection of the UPGMA phenograms indicates identical clusters, so supporting that usefulness of biological parameters to char...
The aim of this study was to find out if reinfection or recrudescence accounted for the recurrence of Helicobacter pylori infections after apparent eradication of the bacterium. Three hundred and twenty patients were treated with colloidal bismuth subcitrate (120 mg four times daily for four weeks), metronidazole and tetracycline (400 mg and 500 mg, respectively, thrice daily for the first week...
This study developed a new multiplex polymerase chain reaction (m-PCR) for rapidly detecting clinically essential strains of V. parahaemolyticus. enables the detection total and potentially virulent strains. The m-PCR was by targeting species-specific transcriptional regulator toxR gene, sequences an outer membrane protein hypothetical encoded omp htp, respectively. htp were discovered original...
Sequence characterized amplifled region (SCAR) markers were derived from random amplified polymorphic DNAs (RAPDs) that segregate in a longleaf pine x slash pine Fi family. Nine RAPD fragments, five from longleafpine and four from slash pine, were cloned and end sequenced. A total of 13 SCAR primer pairs, with lengths between 17 and 24 nucleotides, were developed. Nine (for SCAR loci FGPO04, FG...
background: sarcocystosis in south american camelids (sac) is an important parasitic disease which results in economical loss due to carcass condemnation. meat products from camelids are significant source of animal protein in several american countries. sarcocystis spp. producing macroscopical cysts in these animals have been nominated as s. aucheniae, s. tilopodi, and s. guanicoecanis. the ai...
background: dna isolation procedure can significantly influence the quantification of dna by real time pcr specially when cell free dna (cfdna) is the subject. to assess the extraction efficiency, linearity of the extraction yield, presence of co-purified inhibitors and to avoid problems with fragment size relevant to cfdna, development of appropriate external dna control (edc) is challenging. ...
objective(s) this study planned to assess the value of pcr is6110 assay in tissue specimens of needle pleural biopsy in patients suspicious to pleural tuberculosis. materials and methods sixty eight patients with lymphocytic exudative pleural effusion underwent pleural biopsy. tissue samples were sent for pathologic examination and pcr is6110 assay. the results of pcr reported as positive/ nega...
three tuberculous, twenty-one non-tuberculous mycobacterial (ntm) reference strains and seventy two isolates classified by biochemical tests were shown to produce specific sets of dna fragments in a polymerase chain reaction with single universal primer (up-pcr). a rather wide limit of tolerance for variations in procedure of pcr mixture preparation and thermocycling parameters was found. there...
background and objective: to estimate the risk of human papilloma virus (hpv) infection for cervical malignancies, we conducted a case-control study in southern iran (hormozgan province). materials and methods: for this purpose,52 paraffin embedded blocks with exact diagnosis of cervical carcinoma(50 carcinomas and 2 carcinomas in situ) from 2001 to 2006 and 52 praffin embedded blocks of cervic...
