ELISA Methods for the Detection of Ebolavirus Infection

Ebola viruses are high-priority pathogens first discovered in rural Africa associated with sporadic outbreaks of severe hemorrhagic disease in humans and nonhuman primates. Little is known about the disease ecology or the prevalence of past exposure of human populations to any of the five species of the genus Ebolavirus. The use of immunologic means of detection for either virus antigens or the host's immune response to antigen associated with prior infections offers a powerful approach at understanding the epidemiology and epizootiology of these agents. Here we describe methods for preparing antigen detection sandwich enzyme-linked immunosorbent assays (ELISAs) as well as IgG and IgM ELISAs for the detection of ebolavirus antigens or antibodies in biological samples.
