Fig. 2 in Phlebotomine Sandflies - Potential Vectors of Avian Trypanosomes

Fig. 2. Light microscopy of live T. avium SIM3 trypanosomes in L. longipalpis (A) and P. arabicus (B) gut; Giemsa stained metacyclic trypomastigotes of T. avium (s. s.) strain SIM3 from L. longipalpis hindgut (C). Scanning electron microscopy of T. avium (s. s.) SIM3 in the gut of sandfly P. arabicus (D, E) and L. longipalpis (F). A detailed view of trypomastigotes at the epithelium (D); note the massive infection of trypomastigots covering the gut (E); rounded objects are developmental stages of gregarines Psychodiella chagasi (F).
