To date however, mechanism of protection is not well understood, especially in goat. In this study, HC58 DNA vaccinated goats were artificially infected with 5, 000 dose of infective H. contortus L 3 (third larval stage), and cellular immune responses and abomasum worm burden examined. The results showed that peripheral CD4+, CD8+ T and B lymphocytes for nematode challengedenArticle
