Abstract This study investigates responses of clonal plants and non-clonal to drought their competition results using a spatial simulator based on nonclonal life history strategies. The are designed as two phenotypes one generic species with facultative growth. Therefore, both share the same histories beside allocation aboveground belowground growth, resulting in differences leaf biomass, under...

We report a case of phenytoin-induced pseudolymphoma in a 28-year-old male with a history of autism and seizure disorder. The patient presented with bilateral cervical lymphadenopathy that was shown to be moderately to markedly FDG-avid on a whole body PET/CT scan. Flow cytometry analysis of peripheral blood and bone marrow mononuclear cells detected identical T cell population with aberrant im...

Toxoplasma gondii is one of the most prevalent parasitic infections in world. Rh, NED and Me49 are of the most prevalent clonal types of the parasite isolated till now. Differences in pathogenicity and virulence of different types have been investigated in different studies. No controlled study was performed to compare the ability of different types to initiate humoral immune response. We inves...

To study the population genetic structure of Pseudomonas aeruginosa, we developed a multilocus sequence typing scheme. The sequences of internal fragments of seven housekeeping genes were obtained for 34 P. aeruginosa isolates from patients hospitalized in five different European cities. Twenty-six different allelic profiles were identified. The mean allelic diversity was 0.854 (range: 0.606-0....

The introduction of multilocus sequence typing (MLST) for the precise characterization of isolates of bacterial pathogens has had a marked impact on both routine epidemiological surveillance and microbial population biology. In both fields, a key prerequisite for exploiting this resource is the ability to discern the relatedness and patterns of evolutionary descent among isolates with similar g...

A fundamental problem of asexual adaptation is that beneficial substitutions are not efficiently accumulated in large populations: Beneficial mutations often go extinct because they compete with one another in going to fixation. It has been argued that such clonal interference may have led to the evolution of sex and recombination in well-mixed populations. Here, we study clonal interference, a...
