Figure 1

Transverse section of the anterior intestine of Amatitlania nigrofasciata. Serosa (S), muscularis externa (ME), submucosa (SM) with numerous eosinophilic granule-containing cells (rectangle), and mucosa (M) with epithelial layer (E) and lamina propria (LP), note the brush border (encircled), APUD cells (arrowhead) and goblet cells (arrows). Stain: H-E.

Figure 2

Transverse section of mid intestine of Amatitlania nigrofasciata. Goblet cells (arrows) and thick brush border (encircled). Stain: H-E.

Figure 3

Transverse section of posterior intestine of Amatitlania nigrofasciata. Epithelial cells occupied with numerous, heterogenous supranuclear vacuoles (rectangled) and filled with giant ones (asterisks); note also brush border (encircled). Stain: H-E.

Figure 4

Goblet cells (arrows) in transverse sections of anterior intestine of Amatitlania nigrofasciata stained with different methods: a, AB (pH 2.5); b, PAS; c, AF; d, AB (pH 2.5) followed by PAS.

Figure 5

Goblet cells (arrows) in transverse sections of mid intestine of Amatitlania nigrofasciata stained with different methods: a, AB (pH 2.5); b, PAS; c, AF; d, AB (pH 2.5) followed by PAS.

Figure 6

Transverse section of the posterior intestine of Amatitlania nigrofasciata stained with AB; note vacuolar enterocytes (asterisks) and a few, poorly stained goblet cells (arrows).
