OBJECTIVES The aim of the present study was to develop a simple, quick and cheap method to process whole-blood samples for the molecular techniques polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) without the use of expensive reagents or sophisticated machines. MATERIALS AND METHODS Venous whole-blood samples were collected from 40 individuals. The samples w...

Persistent human papillomavirus (HPV) infection is an essential factor of cervical cancer. This study evaluated the analytical performance of restriction fragment length polymorphism polymerase chain reaction (PCR-RFLP) assay compared to PapilloCheck® microarray to identify human papilloma virus (HPV) in cervical cells. Three hundred and twenty-five women were analyzed. One sample was used for ...

Abstract Background Emergence of fluoroquinolone resistance in gut pathogens is a cause concern. Resistant to quinolone mainly due the point mutations at quinolone-resistance determining regions (QRDR). The aim study was develop polymerase chain reaction-restriction fragment length polymorphism assay (PCR-RFLP) detect QRDR gyrA and gyrB enteric pathogens. Methodology PCR-RFLP done for 83 region...

The assemblages of Giardia duodenalis in 25 children with and 25 children without diarrhoea and 24 adults with gastrointestinal symptoms in South India were determined. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) targeting the glutamate dehydrogenase (gdh), β-giardin and triosephosphate isomerase (tpi) genes was used. The tpi PCR was the most sensitive and dete...

A rapid two-step identification scheme based on PCR-restriction fragment length polymorphism (PCR-RFLP) analysis of the 16S rRNA gene was developed in order to differentiate isolates belonging to the Campylobacter, Arcobacter, and Helicobacter genera. For 158 isolates (26 reference cultures and 132 clinical isolates), specific RFLP patterns were obtained and species were successfully identified...

the major histocompatibility complex (mhc) plays a central role in the control of disease resistance and immune response. extensive genetic diversity in mhc genes provides a valuable source for genetic improvement, via selection, in many domestic animals. exon 2 of the class ii mhc, termed ovar-drb1 in domestic sheep (ovis aries), has been suggested as important disease resistance and immune re...

BACKGROUND/AIMS Clarithromycin resistance is an important factor of Helicobacter pylori (H. pylori) eradication failure in adults and children. There are some tests to determine resistance such as restriction fragment length polimorphism (RFLP), fluorescence in situ hibridisation (FISH), PCR and (culture) agar dilution. Clarithromycin resistance is reported between 16.8%-48.2% in Turkey using P...

The discrimination of Leishmania species from patient samples has epidemiological and clinical relevance. In this study, different gene target PCR-restriction fragment length polymorphism (RFLP) protocols were evaluated for their robustness as Leishmania species discriminators in 61 patients with cutaneous leishmaniasis. We modified the hsp70-PCR-RFLP protocol and found it to be the most reliab...

Twenty-eight enteroviral isolates obtained from various clinical specimens were typed by Lim-Benyesh-Melnick (LBM) pool-based neutralization, PCR-restriction fragment length polymorphism (RFLP), and partial sequencing of the VP1 region of the enteroviral genome. Sequencing was found to be a good alternative to LBM typing, while PCR-RFLP was inadequate for identification of enteroviral isolates.
