On an organ basis, the highest fertility rates were seen in the lungs, rather than the liver, these being the two most commonly infected organs.
However, some larvae continue their migration through the heart and lungs to the systemic circulation where they are distributed via the bloodstream to various organs.
In sheep, unlike cattle, the fertility of hepatic cysts was higher than that in lungs.
The organs examined were the intestine, diaphragm, intercostal muscles, lungs, heart, brain, liver, spleen and kidneys.
In the laboratory, the digestive tract, body cavity, liver and lungs of each individual were examined for the presence of helminths under a stereomicroscope.
At autopsy, lesions on the surface of the livers and lungs were examined morphologically.
Extracting nematodes from lungs or muscle of the deer could not be undertaken.
Accompanying a post-infection increase in host immune cells in the lungs, there was evidence of reciprocal tegumental damage to the parasites.
