E. multilocularis commonly occurs in the posterior part of small intestine and rarely were found in anterior part. Even during very intensive infection, when they are distributed in whole intestine, in posterior part they are usualy signifficantly more frequent.
From my investigation: "...The tapeworms were most frequently found in the posterior part of the small intestine (95% of infected foxes), then in the middle part (80% of foxes), and in the anterior part (55% of foxes).No tapeworms occurred only in the anterior part..".- I attached the artice with full description of these results.

Thanks Jacek. I was aware of that and of your paper, but thanks for sharing. I read it with interest. My question was more on the distribution of the worms on the mucosa that is affected: are they uniformly distributed on the intestine mucosa (regardless of which section), or are they found attached in patches?
why do you think that intensity was low ? mean intensity about 500 worms per animal it is not "so bad" :) . Of course some foxes had only single worms but there were also ones with hundrets or thousands EM, - normal situation.
