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 Italian-native Mediterranean brown trout (Salmo ghigii) is a seriously threatened freshwater fish, especially by anthropogenic hybridisation with the domestic strains of Atlantic origin that have been repeatedly released into wild for angling. A PCR-restriction fragment length polymorphism (RFLP) assay diagnostic lactate dehydrogenase chain-1 (LDH-C1) gene sequences has routinely applied to...

Mytilus galloprovincialis is one of three smooth shelled blue mussel species belonging to the Mytilus edulis species complex. Naturally occurring and introduced populations of M. galloprovincialis are widely distributed throughout many regions of the globe. Mytilus galloprovincialis includes morphologically indistinguishable Northern and Southern hemisphere mtDNA lineages that have been separat...

In this study, we have evaluated our recently developed polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay for the molecular subtyping of Shiga toxin-producing Escherichia coli (STEC). A total of 200 STEC strains including O157 (n=100), O26 (n=50), O111 (n=10), and non-O26/O111/O157 (n=40) serogroups isolated during 2005-2006 in Japan, which were identified to b...

The kinesin is the main motor protein in the trafficking system of the mitochondria and other organelles. Genetic variants affecting the function of kinesin were earlier found to be associated with cognitive disturbances and neurodegeneration. A multiplex polymerase chain reaction (mPCR) method, allowing the simultaneous detection of the KNS2 A185C (rs_1054080) and C406T (rs_3742465) mutations ...

BACKGROUND & OBJECTIVE Glycoprotein B (gB), involved in cell-to-cell transmission of human cytomegalovirus (HCMV), is a critical factor in tissue tropism and viral pathogenesis. The aim of the present study was to compare the efficiency of PCR-based RFLP and multiplex nested PCR for gB gene of HCMV to determine their genotype in clinical specimens from patients with HCMV. METHODS The PCR base...

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...
