Since 1993, all Mycobacterium tuberculosis isolates recovered in the province of Manitoba, Canada, have been genotyped by the standard IS6110-restriction fragment length polymorphism (RFLP) method for routine surveillance, prevention, and control purposes. To date, our laboratory has collected 1,290 isolates, from which we have identified approximately 390 unique fingerprint patterns or "types....

In order to detect several new HLA-A class I alleles that have been described since 1998, the original PCR-RFLP method developed to identify the 78 alleles recognized at that time at high resolution level was adapted by us for low and medium resolution levels using a nested PCR-RFLP approach. The results obtained from blood samples of 23 subjects using both the PCR-RFLP method and a commercial ...

Pyocine production typing and restriction fragment length polymor¬ phism (RFLP) of plasmid DNA with BamHl (BamHl RFLP) were com¬ pared for intraspecies discrimination of 1 00 Pseudomonas aerugi¬ nosa isolâtes. Typeability of pyocine production method was 76% while that of BamHl RFLP was 100%. BamHl RFLP was highly discriminative so as to distinguish unrelated isolâtes of close lineage. However,...

A PCR-restriction fragment length polymorphism (RFLP) method was developed in order to screen a large number of strains for impaired adhesion to epithelial cells due to expression of truncated InlA. inlA polymorphism was analyzed by PCR-RFLP in order to correlate inlA PCR-RFLP profiles and production of truncated InlA. Thirty-seven Listeria monocytogenes strains isolated from various sources, i...

A new convenient molecular typing method, simultaneous polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis, for three different genes of methicillin-resistant Staphylococcus aureus (MRSA) was evaluated using 35 isolates of MRSA and comparing results with those previously reported for sequencing-based spa typing. Twenty-nine isolates of the most frequent prot...

The polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) experiment has the characteristics of low-cost, rapidity, simplicity, convenience, high sensitivity and specificity; thus, many small medium laboratories use it to perform all kinds single nucleotide polymorphisms (SNPs) genotyping works, as a molecular biotechnology for disease-related analysis. However, lack ava...

BACKGROUND In 2009, 3 genome-wide association studies implicated IL28B single-nucleotide polymorphisms (SNPs) as the strongest genetic pretreatment predictor of sustained virological response (SVR) in hepatitis C infection. Recently, the American Association for the Study of Liver Diseases (AASLD) and the European Association for the Study of the Liver (EASL) included IL28B testing in their gui...

A PCR-restriction fragment length polymorphism (RFLP) analysis method that analyzes a part of the dnaJ gene was designed for the rapid and accurate identification of Staphylococcus spp. XapI or Bsp143I digestion of the PCR-generated products rendered distinctive RFLP patterns that allowed 41 reference species and subspecies to be identified with a high degree of specificity. The novel method wa...

Advances in the molecular epidemiological analysis of this disease have greatly improved t...

Calreticulin (CALR) mutations are included in the WHO diagnostic criteria of Myeloproliferative Neoplasm (MPN). Presence CALR mutation, aids their diagnosis by excluding reactive causes. There several molecular techniques to detect mutations; however, these require advanced equipment and technical expertise. An in-house “polymerase chain reaction-restriction fragment length polymorphism (PCR- R...
