| 释义 | caeca plural ofcaecumUKspecialized Examples of caecacaeca Given adequate chemotactic or other directional information, it is not impossible to imagine them making their way into the caeca by their own efforts. None was attached to the intestinal wall and none was found in the pyloric caeca. Two nematode species were recovered from both the gizzard and caeca, and a single nematode species from the proventriculus and crop, respectively. The stomach, pyloric caeca and intestine were separated and opened longitudinally. The caeca are blind parts of the intestine with no continuous through-flow of gut contents. The caeca seem to be periodic in their filling and emptying activities. Some of the intestines and pyloric caeca were processed for histology. The strain used colonized caeca and internal organs of chickens to a high extent 1 week after infection with a low-dose inoculum. The caeca and vitellaria were also adversely affected by drug treatment. Birds were then euthanased and their caeca removed for parasite and parasite egg estimation. Alternatively, immature worms may migrate from the intestine to the pyloric caeca as they develop. Few oocysts could be recovered from caeca given a zero score and therefore these caeca were not used for the selection of a resistant line. The caeca of all chickens were isolated aseptically after necropsy. The columns represent the number of birds from each group, as a percentage, from which the inoculated strain was isolated from the caeca. The crop caeca were also examined for the presence of trypanosome forms. These examples are from corpora and from sources on the web.
