    Las personas han estado usando juegos mayormente con propósitos de ntretenimiento, sin embargo los juegos siempre han tenido una naturaleza educativa intrínseca. debido a esta naturaleza, las personas han creado juegos para propósitos educativos, con un adicional de motivación, atractivo y diversión. consecuentemente, los expertos han observado que los juegos son herramientas excelentes para el aprendizaje. (hamdaqui, khalidi, & bennani, 2014). Este estudio de investigación acción explora los resultados de usar juegos para enseñar vocabulario a estudiantes jóvenes adultos de inglés como idioma extranjero, con bajo nivel del idioma y problemas de motivación para el aprendizaje. Esta investigación comparó los resultados de enseñar vocabulario con juegos educacionales en contraste con el método tradicional.GuayaquilMaestría en Enseñanza del Inglés como Lengua Extranjer

    Genes encoding two <i>Theileria parva</i> antigens recognized by CD8<sup>+</sup> T-cells exhibit sequence diversity in South Sudanese cattle populations but the majority of alleles are similar to the Muguga component of the live vaccine cocktail

    <div><p>East Coast fever (ECF), caused by <i>Theileria parva</i> infection, is a frequently fatal disease of cattle in eastern, central and southern Africa, and an emerging disease in South Sudan. Immunization using the infection and treatment method (ITM) is increasingly being used for control in countries affected by ECF, but not yet in South Sudan. It has been reported that CD8<sup>+</sup> T-cell lymphocytes specific for parasitized cells play a central role in the immunity induced by ITM and a number of <i>T</i>. <i>parva</i> antigens recognized by parasite-specific CD8<sup>+</sup> T-cells have been identified. In this study we determined the sequence diversity among two of these antigens, Tp1 and Tp2, which are under evaluation as candidates for inclusion in a sub-unit vaccine. <i>T</i>. <i>parva</i> samples (<i>n</i> = 81) obtained from cattle in four geographical regions of South Sudan were studied for sequence polymorphism in partial sequences of the Tp1 and Tp2 genes. Eight positions (1.97%) in Tp1 and 78 positions (15.48%) in Tp2 were shown to be polymorphic, giving rise to four and 14 antigen variants in Tp1 and Tp2, respectively. The overall nucleotide diversity in the Tp1 and Tp2 genes was π = 1.65% and π = 4.76%, respectively. The parasites were sampled from regions approximately 300 km apart, but there was limited evidence for genetic differentiation between populations. Analyses of the sequences revealed limited numbers of amino acid polymorphisms both overall and in residues within the mapped CD8<sup>+</sup> T-cell epitopes. Although novel epitopes were identified in the samples from South Sudan, a large number of the samples harboured several epitopes in both antigens that were similar to those in the <i>T</i>. <i>parva</i> Muguga reference stock, which is a key component in the widely used live vaccine cocktail.</p></div

    <p>(A) Multiple sequence alignment of the four Tp1 antigen variants. Antigen variants Var-1, -3 and -9 were first described by Pelle et al. (2011) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0171426#pone.0171426.ref017" target="_blank">17</a>]. (B) Multiple sequence alignment of 14 Tp2 antigen variants. The naming of the antigen variants follows the nomenclature by Pelle et al. (2011) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0171426#pone.0171426.ref017" target="_blank">17</a>]. Antigen variants Var-1, -2 and -5 were first described by Pelle et al. (2011) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0171426#pone.0171426.ref017" target="_blank">17</a>]. The CD8<sup>+</sup> T-cell target epitopes are boxed and the polymorphic residues in the epitopes are shown in red. The frequency of each variant amongst the samples tested is indicated in square brackets. Residues conserved in all sequences are identified below the alignment (*). The shaded flanking regions are equivalent to the positions of the secondary (nested) PCR primers, and are not included in estimations of the percentage of the residues that are conserved.</p
