Fig. 4From: Isolation of infectious Theileria parva sporozoites secreted by infected Rhipicephalus appendiculatus ticks into an in vitro tick feeding systemDemonstration of infectivity of secreted T. parva sporozoites collected from the in vitro tick feeding system. a Flow cytometric detection of cultured T. parva-infected lymphocytes. b Immunocytochemistry demonstrating T. parva schizont formation in bovine lymphocytes. Lymphocytes were probed with monoclonal antibodies: left panel, isotype control; right panel, anti-PIM. Red indicates antibody-specific reactivity to T. parva within bovine lymphocytes.
