Abstract
Sudan virus (SUDV) causes severe lethal hemorrhagic fever in humans and nonhuman primates. The most effective and economical way to protect against Sudan ebolavirus disease is prophylactic vaccination. However, there are no licensed vaccines to prevent SUDV infections. In this study, a bacterium-like particle (BLP)-based vaccine displaying the extracellular domain of the SUDV glycoprotein (eGP) was developed based on a gram-positive enhancer matrix-protein anchor (GEM-PA) surface display system. Expression of the recombinant GEM-displayed eGP (eGP-PA-GEM) was verified by Western blotting and immunofluorescence assays. The SUDV BLPs (SBLPs), which were mixed with Montanide ISA 201VG plus Poly (I:C) combined adjuvant, could induce high SUDV GP-specific IgG titers of up to 1:40,960 and robust virus-neutralizing antibody titers reached 1:460. The SBLP also elicited T-helper 1 (Th1) and T-helper 2 (Th2) cell-mediated immunity. These data indicate that the SBLP subunit vaccine has the potential to be developed into a promising candidate vaccine against SUDV infections.

Abstract
Introducción. El virus del Ébola, antes llamado fiebre hemorrágica del Ébola, es una enfermedad altamente contagiosa con mortalidad entre 50% y 90%, para la cual existen prometedoras opciones de tratamiento que se encuentran en fase de evaluación y uso compasional.Objetivos. Revisar la mejor evidencia médica publicada y analizar el comportamiento de las epidemias por virus del Ébola, sus manifestaciones clínicas, sus complicaciones, los elementos más significativos para su diagnóstico y las nuevas opciones terapéuticas disponibles, para así aprender y aplicar estas experiencias en nuevos brotes.Materiales y métodos. Se realizó una búsqueda sistemática en las bases de datos PubMed, ProQuest, Embase, Redalyc, Ovid, Medline, DynaMed y ClinicalKey durante el periodo 2009-2017 en el contexto internacional, regional y local.Resultados. La revisión sistemática de artículos aportó un total de 51 430 registros, de los cuales 772 eran elegibles; de estos, 722 no eran relevantes, por lo que quedaron incluidos 50. A punto de partida se pudieron precisar los aspectos objeto de esta revisión.Conclusión. La enfermedad causada por el virus del Ébola, a pesar de su alta mortalidad, puede ser prevenida, diagnosticada oportunamente y tratada con efectividad, lo cual permite evaluar su impacto epidemiológico en las áreas endémicas y a nivel mundial. Existe un potencial arsenal terapéutico en fase de experimentación con resultados prometedores.
