Immunocytochemistry against Giardia intestinalis in the duodenal villi of gerbils at 30 days of age.
(4A) Control animal; (4B) infection with the reference isolate WB; (4C to 4F) infection with the HGINV isolate. The duodenal epithelium from the controls and those infected with the WB isolate exhibited a normal appearance with an intact brush border (arrows). WB (4B) trophozoites were found on the brush border (T). HGINV trophozoites were found heading toward the interior epithelium (4C), between the nuclei of epithelial cells (4D), in the centre of the villi in the lacteal vessels (4E) and at the base of empty goblet cells (4F). Lumen (L); trophozoites inside the intestinal epithelium (*); lacteal vessels (LA); goblet cell (GC); lymphocyte (arrow head). Counter-staining with haematoxylin, 100x.
