“…The occurrence of only close-type cells in A. bimaculatus, coincided with other studies that also found only this type of cells in C. argus and in the yellow catfish Pelteobagrus fulvidraco (Pan et al, 2000b). Moreover, no GAS-IR cells were found in the stomach of the catfish R. quelen that was present only in the intestine (Hernández et al, 2012), indicating that the distribution of this hormone can vary depending on the species examined.…”

“…Several earlier studies used antibodies produced in mammals and obtained consistent results in fishes, proving the affinity of the antibodies (e.g., Ku et al, 2004;Hernández et al, 2012;Vieira-Lopes et al, 2013). According to Langer et al (1979), the cross-reactivity strongly suggests that peptides in teleosts fishes share similar or even identical epitopes with their equivalents in higher vertebrates.…”

“…In O. hepsetus, 5-HT-IR cells were observed only in the regions of the stomach, both in the lining epithelium and the glandular epithelium, as also observed in C. herzi by Lee et al [44] . As was described for the fish species Oncorhynchus mykiss [54] , Salmo trutta [55] , Odontesthes bonariensis [56] and Rhamdia quelen [57] , in O. hepsetus we observed CCK-IR cells in the intestine; in this case only in the posterior part, while in O. bonariensis [56] these cells were observed throughout the gut, but with greater concentration in the hindgut. There were no CCK-IR cells in the other regions of the DT of O. hepsetus.…”

AIM:To describe the histology of the digestive tract and to investigate the occurrence of endocrine cells in Oligosarcus hepsetus (O. hepsetus ). METHODS:The digestive tract (DT) of O. hepsetus was divided into esophagus, two stomach regions (glandular and non-glandular) and two intestinal regions (anterior and posterior). These specimens were processed by routine histological techniques and stained with hematoxylin-eosin, Gomori's trichrome, periodic acid Schiff (PAS) and Alcian blue (AB). An immunohistochemical method using avidin-biotin-peroxidase was employed. RESULTS:The esophagus is lined with a non-keratinized stratified squamous epithelium that is reactive to PAS and AB. The stomach has a mucosa lined with a simple columnar epithelium with mucus-secreting cells that are reactive only to PAS. The intestine has a simple columnar epithelium with a brush border and goblet cells that are reactive to PAS and AB. Somatostatin, serotonin and cholecystokinin immunoreactive cells were identified throughout the DT. CONCLUSION:This study revealed adaptations for the species' diet and showed that the distribution and relative frequency of immunoreactive cells are similar to those of other fish.

Goblet cells (GCs) and endocrine cells (ECs) play an important role in intestine physiology, and few studies currently exist for Amazonian fishes. This study aimed to quantify the distribution of GCs and ECs producing cholecystokinin‐8 and neuropeptide Y, assessed by mucin histochemistry and peptides immunohistochemistry, in the intestine of two Amazonian species with different feeding habits Tambaqui (Colossosoma macropomum) and hybrid catfish (Pseudoplatystoma reticulatum × Leiarius marmoratus), an omnivore and carnivore, respectively. A systematic literature review correlating feeding habit and GC and EC distribution was also included to contribute to the comparative study. The results of this study provided novel information about the gut cells of Tambaqui and hybrid catfish. Both, GCs and ECs can be found sweeping the entire intestine of Tambaqui and hybrid catfish although the cells can be more concentrated in certain segments. The GCs and ECs in Tambaqui were more uniformly distributed in the midgut segments (T1, T2, and T3). Unlike, in hybrid catfish GCs were more concentrated in the hindgut (C4) and ECs mainly in the two midgut segments (C1 and C2) of hybrid catfish. Based on the comparison between Tambaqui, hybrid catfish, and other fishes in the literature review, we suggest that cell distribution can be partially explained by feeding habits, carnivorous vs. omnivorous.
