animal’s digestive tract expelled
through the anus during
defecation.
Feces
is
the study of
feces
Scatology or coprology
Produces strong odor and flatus
BACTERIAL METABOLISM
Lactose intolerance leads to excessive gas production
Bacterial metabolism
Major site for final breakdown and reabsorption of compounds
Small intestine
DIGESTIVE ENZY MES
Trypsin,
Chymotrypsin
Lipase,
Amino Peptidase
Amino Lipase
deficiency in enzymes
Osmotic diarrhea
Increase liquidity and frequency of more than three times per day
Diarrhea
Increase daily stool (above 200g)
Diarrhea
MAJOR MECHANISM diarrhea
Secretory diarrhea
Osmotic diarrhea
Intestinal hyper motility
Bacterial, viral, and protozoan infections produce increase secretion of water and electrolytes, which override the reabsorptive ability of the large intestine.
Secretory diarrhea
usually caused by an organism that produces a toxin that stimulates adenylase cyclase enzyme that leads to crampy diarrhea and secretion of intestinal fluid.
Secretory diarrhea
Secretory diarrhea Stool characterized as.
Watery
Mucus
Wbc
Voluminous No rbc
Causative agent of secretory diarrhea
Vibrio cholera
Etec (traveler’s bacterial diarrhea)
Giardia lamblia
Mostly caused by bacteria
Invasive diarrhea
Invasive organism destroy the mucosal lining of the intestines producing pus, blood, and mucus in stool
Invasive diarrhea
Invasive diarrhea Stool may contain:
WBC
RBC
speck of mucus
Patient is experiencing tenesmus
Invasive diarrhea
Invasive diarrhea Caused by:
Shigella
Entamoeba histolytica
EIEC (enteroinvasive escherichia coli)
Incomplete breakdown of reabsorption of food presents increased fecal material to the large intestine, resulting in the retention of water and electrolytes in the large intestine
Osmotic
Mechanism: Usually caused by inefficient reabsorption of an osmotic substance due to an enzyme deficiency
Osmotic diarrhea
