Differences were detected in the gene expression of strains of E. histolytica using RNA (RAP-PCR) and DNA fingerprinting (RAPD). Analysis of the electrophoretic profiles of the gels revealed some polymorphic markers that could be used in the individual characterization of the strains. The 260 bands generated by using five different primers for RAP-PCR, as well as RAPD, were employed in the cons...

OBJECTIVE To evaluate genus- and species-specific polymerase chain reactions (PCRs) for the detection of the genus Legionella and the species Legionella pneumophila in clinical specimens and hospital water supplies, and to establish a simple and reproducible random amplification of polymorphic DNA (RAPD)-PCR technique for genotyping of Legionella. MATERIALS AND METHODS A total of 70 respirato...

conclusions our results showed that blaoxa-23 was the most prevalent gene, followed by blaoxa-51, among the burn and non-burn clinical isolates of a. baumannii. blaoxa-24-like genes were detected at a lower level and were only found among the burn isolates, which also showed higher heterogeneity compared to the non-burn group. background emergence of multidrug-resistant acinetobacter baumannii ...

The purpose of this study was to determine the utility of RAPD-PCR and antibiotic susceptibility tests in differentiation of S. typhimurium isolates in Iran. Thirty isolates of S. typhimurium, selected based on animal source; place and time of the isolation and a reference strain of the bacterium were used in this study. Serotyping of the isolates was performed by reliable antisera and confirme...

Proteus mirabilis is one of the most important pathogens associated with complicated urinary tract infections (acute pyelonephritis, bladder infections, kidney stones) and bacteremia, affecting patients with anatomical abnormalities, immunodeficiency, and long-term urinary catheterization. For epidemiological purposes, various molecular typing methods, such as pulse-field gel electrophoresis (P...

Introduction The quality of DNA, obtained by various protocols and subjected to various storage conditions can be judged by comparing the PCR amplification profiles. The most commonly used technique that can be accessed by almost any laboratory is RAPD . Random amplified polymorphic DNA (RAPD) is a PCR based technique for identifying genetic variation. It involves the use of a single arbitrary ...

The objective of this work is to present an appropriate set of RAPD (random amplified polymorphic DNA) markers using single and multiplex PCR analysis suitable for the characterization of the endemic Cuban species Carica cubensis and the establishment of genetic relationships with the cultivated species Carica papaya. RAPD markers presented a high level of polymorphism. In addition, the incorpo...

Drug susceptibility profile of 53 Mycobacterium tuberculosis clinical isolates was studied by conventional solid and liquid culture methods. Forty three isolates were drug resistant to at least one drug and 10 were susceptible. The strain identification was performed by PCR amplification of mtp40 gene and strain subtyping was performed by Double Repetitive Element-PCR (DRE-PCR), IS6110 outward ...

Genetic relationships among 132 strains of Vibrio vulnificus (clinical, environmental, and diseased-eel isolates from different geographic origins, as well as seawater and shellfish isolates from the western Mediterranean coast, including reference strains) were analyzed by random amplified polymorphic DNA (RAPD) PCR. Results were validated by ribotyping. For ribotyping, DNAs were digested with...
