IMMUNOLOCALISATION OF MIDGUT ANTIGEN OF RHIPICEPHALUS HAEMAPHYSALOIDES BY INDIRECT IMMUNOPEROXIDASE TEST USING METHYLENE GREEN COUNTER STAIN

Abstract
Immunolocalisation of midgut antigen of Rhipicephalus haemaphysaloides was performed by indirect immunoperoxidase test using methylene green as counter stain. Semi engorged adult female ticks were fixed in bouins fixative, embedded in paraffin wax and sectioned. The tick sections were treated with sera from immunized animals showed positive brown colour reaction on the entire surface of digestive cells and midgut epithelial membrane. The methylene green was used for counter staining which clearly differentiated the midgut from other tick tissues.
