Display of FliC131 on the Surface of Lactococcus lactis as a Strategy to Increase its Adjuvanticity for Mucosal Immunization.

Research on innovative mucosal adjuvants is essential to develop new vaccines for safe mucosal application. In this work, we propose the development of a Lactococcus lactis that expresses a variant of flagellin on its surface (FliC131*), to increase the adjuvanticity of the living cell and cell wall-derived particles (CWDP). We optimized the expression of FliC131*, and confirmed its identity and localization by Western blot and flow cytometry.

Activos de salud, calidad de vida y morbimortalidad de la población en Asturias.

IntroducciÓn: n promoción de la salud se ha detectado en los últimos años un incremento de investigaciones con enfoques teóricos basados en activos de salud. Pese a los estudios identificados, no se dispone de suficiente evidencia sobre los efectos que diferentes tipos de activos pueden tener en la calidad de vida y en la morbimortalidad de la población.

Objetivo: analizar la relación entre los activos de salud disponibles con indicadores de morbilidad, mortalidad y calidad de vida de la población asturiana en el año 2018.

Pre-vaccine rotavirus surveillance in Buenos Aires, Argentina. Characterization of an emergent G1P[8] strain associated to fatal cases in 2014.

Group A rotaviruses (RVA) are the most frequent etiological agents causing severe diarrhea in infants and surveillance of genotype, and genetic characteristics of circulating strains are necessary in order to evaluate vaccine programs. The objectives of this work were to describe G and P genotype from 2012 through 2014 in Buenos Aires, Argentina completing an overview of 19 years of genotype surveillance in our region and to characterize an emerging G1P[8] strain associated with severe cases and five fatalities in 2014. We performed genotyping by RT-PCR.

Specific diagnostic method for St. Louis encephalitis virus using a non-structural protein as the antigen.

St. Louis encephalitis virus (SLEV) is a mosquito-borne re-emerging flavivirus in Argentina. It is currently necessary to develop specific serological tests that can efficiently discriminate the flaviviruses that circulate in our country.
