ANDERSON, P. J. S. & VERSTER, ANNA, 1971. Studies on Dictyocaulus filaria. II. Migration of the developmental stages in lambs. Onderstep oort]. vet. Res. 38 (3), 185190 (1971). Developmental stages of D ictyocaulus filaria (Rudolphi, 1809) were recovered from the right colic mesenteric lymph nodes of lambs 18 hours after infestation . The majority of the parasites remain in the lymph nodes until D ay 6 and from Day 7 onwards migrate via the thoracic duct to the heart and pulmonary arteries. From D ay 8 to Day 14 parasites occur in considerable numbers in the lung tissue. Although some worms may be present in the trachea and bronchi on D ay 4, they are not present in large numbers prior to Day 10. From the 12th day the numbers in the lung tissue decrease while those free in the respiratory passages increase.

Analysis of the transcriptome of adult Dictyocaulus filaria and comparison with Dictyocaulus viviparus, with a focus on molecules involved in host-parasite interactions.

In spite of their economic importance, very little is known about the immunomolecular biology of these parasites. Here, we conducted...
