| determinants of host specificity and comments on attachment site specificity of tetraphyllidean cestodes infecting rajid skates from the northwest atlantic. | the objectives of this study were to (1) describe the host range for 6 tetraphyllidean species and quantify their host specificity using 5 specificity indices; (2) determine the role of morphological determinants in the host specificity of tetraphyllideans by comparing villar and bothridial measurements of species examined herein; and (3) determine the role of a physiological component in the host specificity of tetraphyllideans by exposing tetraphyllideans to blood sera from different fish spec ... | 2008 | 18564745 |
