This study aims to characterize different Salmonella enterica subsp molecularly. strains (n=49) were isolated from human gastrointestinal cases in the Tolima region and poultry Santander regions using PCR-RFLP, PCR-ribotyping, PCR-SSCP. The band patterns obtained with each technique analyzed by building dendrograms based on Unweighted Pair Group Method Arithmetic mean (UPGMA) method Dice coeffi...

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...

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...

Ghost crabs (genus Ocypode spp.) found on sandy beaches are susceptible with the loss of an ecotone, making them useful as indicators anthropogenic alteration, such seawall construction. On Sendai Bay Pacific coast Tohoku region northern Japan, three species have been sympatrically observed in recent years: O. stimpsoni, ceratophthalmus, and sinensis. However, these only occur from late summer ...

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...

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...

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...

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.

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...
