Anyone here know that during the eating process, bacteria will totally been grinded by pharynx or some bacteria maybe also get through the pharynx and further been digested or exocytosis by intestine cells? ???
Apparently, bacteria are mechanically digested by the pm6 ‘grinder’ cells prior to entry into the intestine. However, I’ve fed OP50-GFP to worms and observed bacteria entering the intestine in older adults (>125 post hatching), but this was pretty rare and limited to the lumen of anterior intestinal cells.
