bacteria usually cause disease in the gastrointestinal tract by colonization and growth in the gastrointestinal tract, where the micro organisms may invade the tissues of host or secretion of an exotoxin that is performed in food and then ingested by the host, examples of second group include: staphylococcal, bacillus cereus, clostridial (c.botulinum and c.perfringens type a) toxin. in this stu...

background: the iron deficiency anemia (ida) is a common cause of referral to medical departments. chronic gastrointestinal (gi) blood loss is important cause of ida and also an alarming sign of serious underlying disease. the information concerning ideal evaluation of the gastrointestinal tract in patients with the ida is scant. we designed a prospective study to determine the frequency of gi ...

cytomegalovirus is the most common viral infection after kidney transplantation. clinical presentations of cytomegalovirus infection range from asymptomatic infection to organ-specific involvement. most symptomatic infections manifest as fever and cytopenia. the gastrointestinal tract is the most common site of tissue-invasive infection, often presenting as diarrhea or gastrointestinal bleeding...

The protein content of the gastrointestinal tract is not more than 7 % of whole-body protein, while the amount of protein synthesized daily exceeds 20% of whole-body protein synthesis. Considering this active protein metabolism in the gastrointestinal tract as well as the role of the gastrointestinal tract in digestion and absorption, we have investigated fluxes of N and amino acids (AA) in rel...
