Restriction Fragment Length Polymorphism (RFLP) is a technique in which organisms may be differentiated by analysis of patterns derived from cleavage of their DNA. If two organisms differ in the distance between sites of cleavage of a particular restriction endonuclease, the length of the fragments produced will differ when the DNA is digested with a restriction enzyme. The similarity of the pa...

conclusions the results of antifungal susceptibility tests demonstrated that voriconazole was the most active drug against candida isolates. candida albicans is the most common yeast isolated from human blood world-wide; the unexpectedly higher rate of c. parapsilosis isolated in this study necessitates more studies with larger sample sizes in iran. results candida parapsilosis (c. parapsilosis...

background interleukin-16 (il-16) is an immunomodulatory cytokine, which plays an important role in some inflammatory and autoimmune diseases such as hepatitis b, which is a major health concern worldwide. objectives in this study, we aimed to investigate the plausible association between il-16 polymorphism and chronic hbv susceptibility in an iranian population. conclusions these findings show...

background: recurrent spontaneous abortion is one of the diseases that can lead to physical, psychological, and, economical problems for both individuals and society. recently a few numbers of genetic polymorphisms in kinase insert domain-containing receptor (kdr) gene are examined that can endanger the life of the fetus in pregnant women. objective: the risk of kdr gene polymorphisms was inves...

A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for detection of cry11 genes from Bacillus thuringiensis was established. Based on the analysis of conserved regions of the cry11 genes, 2 oligonucleotide primers were designed to amplify a 1459-bp fragment of the cry11Aa gene, and a 1471-bp of the cry11Ba and cry11Bb genes. The amplification products were di...

background chronic hepatitis b virus (hbv) infection is a multifactorial disease that can result in serious clinical complications. host genetic background especially the genes that encode immunologic factors like inf-γ and its receptor (ifn-γ r) are critical in the pathogenesis of infection. materials and methods genomic dna from peripheral blood samples of 200 chronically hbv infected patient...

conclusions methicillin-resistant staphylococcus aureus is an increasingly common cause of nosocomial infections. our results are in agreement with those of other studies reporting that a few specialized clones are responsible for most cases of mrsa nasal carriage. in this study, mrsa strains isolated from different wards of hospital were closely related when analyzed by coagulase gene typing. ...

We developed an alternative nested-PCR-restriction fragment length polymorphism (RFLP) protocol for the detection of Cyclospora cayetanensis in environmental samples that obviates the need for microscopic examination. The RFLP method, with the restriction enzyme AluI, differentiates the amplified target sequence from C. cayetanensis from those that may cross-react. This new protocol was used to...
