An indirect immunoperoxidase procedure using a specific anti- Ehrlichia risticii monoclonal antibody and an avidin-biotin-peroxidase staining method was used to detect E. risticii antigen in infected P388D1 murine monocytes. Several different methods of cytological fixation were used, including acetone (15 min), 95% ethanol (15 min), Bouin's fixative (5 hr), and 10% buffered neutral formalin (24 hr). The E. risticii organisms were labeled effectively and identified in cells fixed with acetone and ethanol. However, infected P388D1 cells fixed in 10% formalin or Bouin's fixative required enzymatic digestion with 1.0% trypsin for 15 min at 37 C before positive results were evident. This indirect immunoperoxidase avidin-biotin staining procedure proved to be a sensitive assay for the detection of intracellular E. risticii and may be an effective diagnostic procedure for formalin-fixed paraffin-embedded tissue.
