feces
Problems with evacuation of feces have plagued people since the beginning of time.
      
Diagnosis relies on demonstration of schistosome eggs in feces or tissue.
      
Baylisascaris procyonis, a parasitic infection of raccoons, causes severe neurologic and ocular disease in humans when infectious eggs from raccoon feces are ingested.
      
The experimental results showed that the fecal coliform (FC) to fecal streptococcus (FS) ratio (FC/FS) in the human feces and in warm-blooded animal feces were rather different.
      
FC/FS ratio in the human feces was greater than 7.0, and in warm-blooded animal feces was less than 1.0.
      
66.43% of the total amount of the pesticide administered was excreted in feces and urine, especially in feces.
      
DNA microcapsules and microspheres were recovered intact from rat feces following gavage and gastrointestinal transit.
      
The eight adult males who participated in the first study lost significantly more selenium in their feces when fed a test diet containing 50 mg tin daily than when fed the control diet containing 0.1 mg tin daily.
      
Radioisotope-dilution technique for determining endogenous manganese in feces of the growing rat
      
Rat pups, however, are coprophagic and begin to consume the maternal feces in their second postnatal week.
      
This experiment was designed to determine whether the maternal feces are a significant source of Pb in pups exposed via the lactating dam.
      
Half of the litters from intubated dams had continuous access to maternal feces throughout the lactation period, whereas access was curtailed at P14 in the other litters.
      
Lead content of the feces from Pb-exposed dams ranged from 1000 to 5000 μg Pb/g wet wt.
      
At P21, Pb concentrations were 2-4 times higher in blood, brain, bone, and liver of pups that had access to Pb-contaminated feces than in pups that were exposed to Pb primarily through the mother's milk.
      
When estimating exposure levels in pups receiving Pb through the lactating dam, coprophagy and the high content of Pb in the dam's feces must be taken into consideration.
      
Unenriched samples of human milk, feces, and whole blood were prepared similarly to monitor instrumental precision and analytical error.
      
Selenium significantly enhanced fermentation in the colon and rectum, but not in the cecum or feces.
      
Selenium was found in association with the bacterial cell fractions of gut contents and feces: 40-46% of the total Se was associated with colonic microbes and 58% in fecal microbes.
      
However, it could not be assumed that there was no big difference in absorption of the metal in the human body if fractions of consumed Al retained in the body or excreted by bile or feces were considered.
      
In turn, combined administration of zinc and chelating agents significantly reduced the amount of copper found in the feces.
