“…Investigation and comparison of the histochemical distribution of mucous secreting cells in the GIT of various mammalian species of different diets and life histories can assistant in the understanding of the quality and composition of the resulting mucous layer and biofilm formed on the surface of the GIT mucosa (Sheahan and Jervis, 1976;Filipe, 1979;Bollinger et al, 2007).…”

“…The marmoset ceca may serve as a reservoir of bacteria to recolonize the upper colon after the resident bacterial populations have been reduced, perhaps due to the passage of large, hard seeds. The human appendix has been recently suggested to perform such a function, harboring a reservoir of gut microbes that can recolonize the lower gut [Bollinger et al, 2007]. The greater ability of marmosets to ferment gums may, in part, derive from an enhanced ability to maintain large microbial populations within the upper colon.…”

Wild common marmosets (Callithrix jacchus) feed on fruits, insects, and gums, all of which provide different digestive challenges. Much of the ingested mass of fruits consists of seeds. In general, seeds represent indigestible bulk to marmosets and could inhibit feeding if they are not eliminated rapidly. In contrast, gums are (Winked polysaccharides that require microbial fermentation. Their digestion would benefit from an extended residence time within the gut. Earlier research found that mean retention time (MRT) for a liquid digestive marker (cobalt EDTA) was significantly longer than MRT for a particulate marker (chromium-mordanted fiber), suggesting that common marmosets preferentially retain liquid digesta. We conducted two four-day-long digestion trials on 13 individually housed adult common marmosets fed a single-item, purified diet in order to examine the relations among MRT of cobalt EDTA and chromium-mordanted fiber, food dry matter intake (DMI), and apparent digestibility of dry matter (ADDM). We compared the MRT values with the data from the previous study mentioned above and a study using polystyrene beads. There were no significant correlations among MRT, ADDM, or DMI, although increases in DMI between trials were associated with decreases in MRT. ADDM was consistent within individuals between trials; but the mean values ranged from 75.0 to 83.4% among individuals. We found no difference in MRT between the liquid (17.5 +1.6 hr) and particulate (17.9+1.4 hr) markers. Although these values were not significantly different than found previously, the MRT for chromium-mordanted fiber tended to be longer. This probably reflects the relatively small size of the chromium-mordanted fiber particles used in this study. An inverse relationship between particle size and MRT was evident; the mean MRT of polysterene beads, the largest marker, was only 8.3 +1.5 hr. Marmosets appear to retain liquids and small particles within the gut longer than large particles. Am. J. Primatol. 71:957-963, 2009.

Apendix is a worm shaped tubular structure found attached to the ceacum just below the ileocecal junction in humans, some apes and wombats. It's inflammation is the most common disease of the appendix which leads to appendectomy; the most common emergency operation throughout the world. It's different positions are responsible for different clinical presentation apart from common symptoms and on top of that a long subhepatic appendix can further confuse the picture and produce a diagnostic dilemma. Hence a good clinical acumen and a high index of suspicion are required to lower the morbidity and mortality associated with a delayed diagnosis of acute appendicitis.
