Sixty-nine Staphylococcus aureus isolates from two epidemiologically unrelated sources were typed by pulsed-field gel electrophoresis after SmaI digestion of chromosomal DNA (genome typing), and the results were compared with those obtained by other typing methods: phage typing with the international set of phages, capsular serotyping with monoclonal antibodies against capsular polysaccharides ...
The spa gene occurs in all strains of Staphylococcus aureus (S. aureus), can function as a genetic marker and might be used distinguish strains at the species level. Hence, due to these advantages, we used spa typing and the Based Upon Repeat Pattern (BURP) to assign the clonal and phylogenetic relationships of S. aureus strains. The sensitivity of S. aureus strains to methicillin was determine...
Plants use their roots to forage for nutrients in heterogeneous soil environments, but different plant species vastly differ in the intensity of foraging they perform. This diversity suggests the existence of constraints on foraging at the species level. We therefore examined the relationships between the intensity of root foraging and plant body traits across species in order to estimate the d...
Most asexual species of fungi have either lost sexuality recently, or they experience recombination by cryptic sexual reproduction. Verticillium dahliae is a plant-pathogenic, ascomycete fungus with no known sexual stage, even though related genera have well-described sexual reproduction. V. dahliae reproduces mitotically and its population structure is highly clonal. However, previously descri...
Next-generation sequencing has been used to infer the clonality of heterogeneous tumor samples. These analyses yield specific predictions-the population frequency of individual clones, their genetic composition, and their evolutionary relationships-which we set out to test by sequencing individual cells from three subjects diagnosed with secondary acute myeloid leukemia, each of whom had been p...
Social advertising holds the potential to reshape the traditional advertising industry. Understanding what leads to effective social contagion at the dyadic level lies at the core of cost-effective social advertising strategies. This paper is the first attempt to comprehensively study the effect of dyadic network relationship on social contagion in directed networks. This paper reveals several ...
The main objective of this study was to learn whether emotional autonomy is truly part of a developmental stage for Spanish adolescents and young adults or if it is an indicator of difficult family relationships. Using a longitudinal design, a sample of ninety young people was followed for ten years, from their initial adolescence until their first years of adulthood. At four observation points...
