aHistologic detection can be performed with morphologic techniques, in blood or tissue smears, or in tissue sections. Serologic assays can detect specific antibodies to the suspected agent or to a related organism in tissues or in biological fluids. The year of the first isolation and the culture system used are indicated. HUS = hemolytic uremic syndrome. HLE=human embryonic lung fibroblasts; ref = reference.
