Phenotypic variation of Helicobacter pylori isolates from geographically distinct regions detected by lectin typing.
A total of 309 Helicobacter pylori isolates from 18 different countries were analyzed with a previously developed lectin typing system. The system was developed by using a proteolytic pretreatment to enhance the carbohydrate fraction of the sample. Four lectins from Ulex europaeus, Lotus tetragonolobus, Erythrina cristigali, and Triticum vulgaris were used to type the strains. The lectins were ...
متن کاملPhenotypic and genotypic variation in methylases involved in type II restriction-modification systems in Helicobacter pylori.
To determine relationships between Helicobacter pylori geographical origin and type II methylase activity, we examined 122 strains from various locations around the world for methylase expression. Most geographic regions possessed at least one strain resistant to digestion by each of 14 restriction endonucleases studied. Across all of the strains studied, the average number of active methylases...
متن کاملA Geographically Diverse Collection of Schizosaccharomyces pombe Isolates Shows Limited Phenotypic Variation but Extensive Karyotypic Diversity
The fission yeast Schizosaccharomyces pombe has been widely used to study eukaryotic cell biology, but almost all of this work has used derivatives of a single strain. We have studied 81 independent natural isolates and 3 designated laboratory strains of Schizosaccharomyces pombe. Schizosaccharomyces pombe varies significantly in size but shows only limited variation in proliferation in differe...
متن کاملEvaluation of Phenotypic and Genotypic Expression of Efflux Pumpin Clinical Isolates of Acinetobacter baumannii Resistant to Ciprofloxacin and Gentamicin
Introduction: Acinetobacter baumannii is an important bacteria because of high ability to obtain antibiotic resistance genes and creation of multi-drug resistant strains (MDR). Today, the active efflux pumps has been suggested as one of the most important mechanisms of intrinsic and acquired resistance of antibiotics in bacteria. The aim of this study was Evaluation of phenotypic and genotypic ...
متن کاملLewis antigen expression and stability in Helicobacter pylori isolated from serial gastric biopsies.
The expression of Lewis antigens by the gastric pathogen Helicobacter pylori in serial biopsy isolates was investigated to assess antigen distribution and stability. A total of 26 asymptomatic subjects were given various doses of 3' sialyllactose for up to 56 days. Gastric biopsies were performed during the dosing period, as well as 30 days after dosing, which provided 127 H. pylori isolates th...
