This photomicrograph of a Gimenez-stained yolk sac smear revealed the presence of Rickettsia rickettsii bacteria, which are the cause of Rocky Mountain spotted fever (RMSF). These bacteria range in size from 0.2µ x 0.5µ to 0.3µ x 2.0µ. They are difficult to see in tissues by using routine histologic stains, and generally require the use of special staining methods, like the Gimenez stain used in this case.
