This study investigated the morphohistology of the digestive tract and the mean intestinal coefficient of the damsel fish Stegastes fuscus captured from the tidal pools of Northeastern Brazil. The wall of the digestive tract of S. fuscus is composed of the tunica mucosa, tunica muscularis, and tunica serosa. The esophagus is short with sphincter and thick distensible wall with longitudinally fo...

New strategies to prevent or treat diseases have been focusing on innovative approaches, such as the oral administration of living recombinant microorganisms delivering active compounds directly into the human digestive tract. The feasibility of the approach was evaluated using recombinant Saccharomyces cerevisiae expressing a model P450. The survival rate of the yeasts and their ability to con...
