(A) Low magnification of the duodenal epithelium of 21 day-old gerbils inoculated with HGINV isolate. Trophozoites in the submucosa (box) are shown at higher magnification on top. 2B and 2C show electron microscopy images of the top trophozoites denoted whit an asterisk (*). The morphology appeared normal. One nucleus (N) of connective tissue cells in proximity to the trophozoites showed nuclear or cytoplasmic membrane integrity (thick arrows) and preserved mitochondria (M). Serosa (S); lumen (L); vacuoles (V); collagen fibres (CF); adhesive disc (AD); lateral crest (LC); ventrolateral flange (VLF); flagellum (F), axonemes (AX). 2A: 20x toluidine blue; on top 100X. 2B and 2C: 15,000 x.
