The aim of this study was to evaluate the use of one of the molecular typing methods such as PCR (polymerase chain reaction) following by RFLP (restriction fragment length polymorphism) analysis in the identification of Candida species and then to differentiate the identified azole susceptible and resistant Candida albicans strains by using AP-PCR (arbitrarily primed-polymerase chain reaction)....

The aim of the present study was to compare polymerase chain reaction (PCR)-based methods--spoligotyping and mycobacterial interspersed repetitive units (MIRU) typing--with the gold-standard IS6110 restriction fragment length polymorphism (RFLP) analysis in 101 isolates of Mycobacterium tuberculosis to determine the genetic diversity of M. tuberculosis clinical isolates from Delhi, North India....

The potential use of spoligotyping—a polymerase chain reaction based typing system for diVerentiation of strains of Mycobacterium tuberculosis—for studying the epidemiology of tuberculosis in developing countries which do not routinely perform mycobacterial culture is described in this issue of Thorax by Heyderman et al in a study from Zimbabwe. 1 How does this newer method compare with the now...

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 Fusarium species are capable of causing a wide range of crop plants infections as well as uncommon human infections. Many species of the genus produce mycotoxins, which are responsible for acute or chronic diseases in animals and humans. Identification of Fusaria to the species level is necessary for biological, epidemiological, pathological, and toxicological purposes. In this study...

The Mycobacterium tuberculosis Beijing family isolates may cause more than a quarter of all tuberculosis cases worldwide, are emerging in some areas, and are often associated with drug resistance. Early recognition of transmission of this genotype is therefore important. To evaluate the usefulness of variable-number tandem-repeat (VNTR) typing to discriminate and recognize strains of the Beijin...

BACKGROUND AND OBJECTIVES Molecular typing methods are important and useful tools to assess the transmission, diversity of strains and differentiation between new infections and relapses which can effectively help in controlling infections. The aim of this study was to evaluate the molecular typing methods which have been used in Iran. By evaluating the results and discriminatory power of each ...

Repetitive-sequence-based PCR (rep-PCR) is useful for generating DNA fingerprints of diverse bacterial and fungal species. Rep-PCR amplicon fingerprints represent genomic segments lying between repetitive sequences. A commercial system that electrophoretically separates rep-PCR amplicons on microfluidic chips, and provides computer-generated readouts of results has been adapted for use with Myc...

An outbreak of an unusual tetracycline-sensitive, rifampicin- and ciprofloxacin-resistant, methicillin-resistant Staphylococcus aureus (MRSA) strain at a large teaching hospital was investigated. Two typing methods, phage typing and restriction fragment length polymorphism (RFLP) by pulsed-field gel electrophoresis (RFLP-PFGE), gave conflicting results which were clarified by phylogenetic analy...
