The Malayan box turtle (Cuora amboinensis) (MBT) is a vulnerable and protected turtle species, but it is a lucrative item in the illegal wildlife trade because of its great appeal as an exotic food item and in traditional medicine. Although several polymerase chain reaction (PCR) assays to identify MBT by various routes have been documented, their applicability for forensic authentication remai...

PURPOSE Four single-nucleotide polymorphisms (SNPs) in the TGIF, lumican, TGFB1, and HGF genes have been declared to be associated with high myopia in Chinese living in southeast China, but none of them has been confirmed by additional studies. This study was conducted to verify the reported positive association results by analysis of subjects from the same region. METHODS DNA was prepared fr...

We compared genotyping by restriction fragment length polymorphism (RFLP) analysis of the amplified omp1 gene with serotyping by dot enzyme-linked immunosorbent assay (dot-ELISA) to determine the suitability of RFLP analysis for epidemiologic study. Fifteen prototypes of Chlamydia trachomatis and 30 clinical isolates were used in this study. To serotype with dot-ELISA, chlamydia antigen was spo...

BACKGROUND Genetic polymorphisms of drug metabolisms by cytochrome P450 (P450s) could affect drug response, attracting particular interest in the pharmacogenetics. Due to the importance of CYP2C19* 17 allele and its capability of super- fast metabolism and also lack of information about distribution of the alleles in Iranian population, this research aimed to use High Resolution Melting (HRM) m...

Bacterial subclones recovered from an old stab culture of Escherichia coli K-12 revealed a high degree of genetic diversity, which occurred in spite of a very reduced rate of propagation during storage. This conclusion is based on a pronounced restriction fragment length polymorphism (RFLP) detected upon hybridization with internal fragments of eight resident insertion sequences (IS). Genetic d...

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...

Molecular types of the Cryptococcus neoformans/Cryptococcus gattii species complex that infect dogs and cats differ regionally and with host species. Antifungal drug susceptibility can vary with molecular type, but the susceptibility of Cryptococcus isolates from dogs and cats is largely unknown. Cryptococcus isolates from 15 dogs and 27 cats were typed using URA5 restriction fragment length po...

Increased frequency of methicillin-resistant Staphylococcus aureus (MRSA) in hospitalized patients requires rapid and reliable characterization of isolates for control of MRSA spread in hospitals. This study evaluated polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) as a molecular typing technique for MRSA strains on the basis of protein A (spa) and coagulase (coa) ...

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 ...

The adenosine A2a receptor (A2aAR) gene is thought to be involved in essential hypertension because adenosine elicits vasodilation and decreases arterial blood pressure via this receptor, and because disruption of the A2aAR gene increases blood pressure in mice. Therefore, using a restriction fragment length polymorphism (RFLP) of the A2aAR gene, we performed an association study in patients wi...
