In the pastoral variant, sheep serve as the most common intermediate hosts while in the sylvatic variant the usual intermediate hosts are caribou or moose.
In the Northwest Territories and the northern portion of the Canadian Prairie Provinces of Alberta, Saskatchewan and Manitoba, the barren ground caribou is the most common intermediate host [ 2].
Bush dogs (Speothos venaticus) are the most common definitive hosts for E. vogeli cestodes (adult cestode carriers; wild rodents, especially pacas (Cuniculus paca), may be the most common intermediate hosts (larvae or metacestode carriers) (2 ).
Transmission of E. canadensis G7 is considered to be restricted to certain areas in central, southern, and eastern Europe, Spain, Poland, Lithuania, the Slovak Republic, Ukraine, Romania, and Italy [ 12– 16, 26– 30], where the most common intermediate host is the pig.
Another explanation with some scientific support is that adults are most common at intermediate depths, while young sharks are restricted to shallower water and both adults and juveniles are found in deeper water.
For most common and intermediate incidence cancers a firm histological diagnosis is available prior to staging investigations.
Most of the common intermediates were usually found to lead to more than two targets.
The most common situation is intermediate between the two limiting cases described above.
With regard to race/ethnicity, IFG was most common in Hispanics, intermediate in blacks, and least common in whites, similar to results in NHANES (10).
For the categorical variable, we tested preference using the most common higher and intermediate dry steppe/shrub communities as reference category.
