Analiza Trilce (1922), el segundo libro de poemas de César Vallejo que revolucionó los espacios de la crítica literaria peruana e hispanoamericana y generó desconcierto ante la trasformación radical del lenguaje poético. Representa la ruptura con la estética tradicional, con la insuficiencia del discurso poético establecido. La investigación plantea que es una creación particular, no obstante, contiene elementos que coinciden con la vanguardia literaria de la época y que la escritura poética traspasa y crea el arte nuevo.

Antibiotic resistance mediated by bacterial production of extended-spectrum beta-lactamase (ESBL) is a global threat to public health. ESBL resistance is most commonly hospital-acquired; however, infections acquired outside of hospital settings have raised concerns over the role of livestock and wildlife in the zoonotic spread of ESBL-producing bacteria. Only limited data are available on the circulation of ESBL-producing bacteria in animals. Here, we report ESBL-producing Escherichia coli in wild common vampire bats Desmodus rotundus and livestock near Lima, Peru. Molecular analyses revealed that most of this resistance resulted from the expression of blaCTX-M-15 genes carried by plasmids, which are disseminating worldwide in hospital settings and have also been observed in healthy children of Peru. Multilocus sequence typing showed a diverse pool of E. coli strains carrying this resist...
