Clostridium difficile colonization in healthy adults: transient colonization and correlation with enterococcal colonization.
The aim of the present study was to investigate the colonization status of Clostridium difficile in healthy individuals. In total, 139 healthy adults from two study groups were examined at intervals of 3 months. Among the 18 positive subjects, the number of subjects from whom C. difficile was isolated once, twice, three times or four times was 10 (55.6%), three (16.7%), two (11.1%) and three (1...
متن کاملEffects of colonization asymmetries
1 Ocean currents, prevailing winds, and the hierarchical structures of river networks are 2 known to create asymmetries in re-colonization between habitat patches. The impacts of 3 such asymmetries on metapopulation persistence are seldom considered, especially rarely 4 in theoretical studies. Considering three classical models (the island, the stepping stone 5 and the distance-dependent model)...
متن کاملImage Space Colonization Algorithm
This paper describes an image segmentation method based on an evolutionary approach. Unlike other application of evolutionary algorithms to this problem, our method does not require the definition of a global fitness function. Instead a survival probability for each individual guides the progress of the algorithm. The evolution involves the colonization of a bidimensional world by a number of p...
متن کاملColonization and infection
Ureteral stenting (the insertion of the Double-J catheter) is and in the near future will remain one of the most common urological interventions. Consequently , bacterial and fungal complication of this stenting are in the focus of many controversial discussions [1]. These discussions are related not only to differences between patient selections, but also to differences in interpretation of ba...
متن کاملColonization Versus Infection
Most organisms which colonize are harmless commensals and are best left alone. They may, in fact, prevent invasion by pathogens. This happens by competition for nutrition and by producing inhibitory metabolic products. Some commensals can nevertheless invade if they have an opportunity. It is important to remember that most pathogenic organisms set up colonization first and switch to an invasiv...
