The digestive tracts were divided into the foregut, midgut, ileum, rectum, and Malpighian tubules.
The midgut of hymenopterans is a relatively long tube, lined with a single layered epithelium, 2 layers of circular (inner) and longitudinal (outer) muscles, and a peritrophic membrane enclosing the food (Snodgrass 1935; Serrao & Cruz-Landim 1996b).
Labeling of midguts with fluorescein-conjugated HPA confirmed the presence of GalNAc-containing glycoproteins in the midguts of P.
Trypanosoma brucei gambiense and human-blood meals were found in tsetse fly midguts, which suggested active disease transmission.
The midguts were then removed aseptically, and each was placed into a separate vial that contained 2 mL modified Barbour-Stoenner-Kelly medium that could support the growth of small numbers of B.
On the next day, all mosquito pools contained infectious virus in their midguts, representing viremic hamster blood ingested by mosquitoes within the trap.
Field-collected ticks were dissected and their midguts examined for spirochetal infection by dark-field microscopy.
felis-infected flea midguts (FleaData, Inc; Freeville, NY) were dissected and placed into individual wells of a 10-well Tefloncoated antigen slide at two midguts/well and allowed to air dry for 20 minutes.
To confirm that larvae used for xenodiagnosis were free of spirochetes, a sample of each batch was routinely fed on a laboratory-bred mouse; no spirochetes were found when midguts of 20 of the resulting nymphs were examined by dark-field microscopy, and subsequent xenodiagnosis of the mouse showed no evidence of spirochetes.
The midguts were also checked for metacyclic promastigotes to confirm infection.
