Haemophilus parasuis belongs to opportunistic microorganisms of undefined virulence. The purpose of the studies was to compare suitability of PCR/RFLP in our modification and ERIC PCR for epidemiological study of domestic strains of H. parasuis. The results were evaluated taking into account two different aspects: suitability of the tests for isolating the highest possible number of clone group...

Spoligotyping has been suggested as a screening test in multistep genotyping of Mycobacterium tuberculosis strains. Relying on restriction fragment length polymorphism (RFLP) analysis with IS6110 (IS6110 RFLP analysis) as a "gold standard," we performed a comparative evaluation of spoligotyping and ligation-mediated PCR (LMPCR), a recently described PCR-based typing method, as rapid screening t...

To determine the types of Enterocytozoon bieneusi strains associated with intestinal microsporidiosis, we developed a rapid and efficient approach for typing parasites obtained from stool specimens by PCR-restriction fragment length polymorphism (PCR-RFLP). Typing was based on DNA polymorphism of the ribosomal DNA internal transcribed spacer (ITS) region of E. bieneusi. RFLPs generated with two...

In the presented paper, PCR-RFLP and RFLP-PFGE with two different enzymes were applied for the discrimination of 48 Campylobacter isolates from poultry carcasses and faeces. Both used typing methods had a typeability of 100% on this collection of the strains. PFGE with SacII enzyme was the most discriminatory method with the discrimination index of 0.98. Restriction analysis of the flaA gene al...

In this study, we performed fliC PCR-restriction fragment length polymorphism (RFLP) to investigate whether this technique would be better than classic serotyping for the characterization of the H antigen in enterotoxigenic Escherichia coli (ETEC) strains. We showed that the fliC genes from ETEC strains can be characterized by restriction analysis of their polymorphism. Only one allele of the f...

We describe a modified single nucleotide polymorphism (SNP) typing method based on the restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR). This is a simple, economical method without the need for special equipment. For most SNP loci, a common restriction endonuclease (Hind III, EcoR I or BamH I) recognizing site (RER) can be introduced into one allelic form, but not t...
