Experimental Oesophagostomum dentatum infections in the pig: Worm populations resulting from trickle infections with three dose levels of larvae

This paper describes the worm populations in pigs experimentally infected by trickle infections with different dose levels of the nodular worm, Oesophagostomum dentatum. Four groups each of 20 helminth naïve pigs, 10–12 weeks old, were inoculated with 0 (group 1), 100 (group 2), 1000 (group 3), or 1...

Zusammenfassung:This paper describes the worm populations in pigs experimentally infected by trickle infections with different dose levels of the nodular worm, Oesophagostomum dentatum. Four groups each of 20 helminth naïve pigs, 10–12 weeks old, were inoculated with 0 (group 1), 100 (group 2), 1000 (group 3), or 10,000 (group 4) infective larvae twice weekly, and the pigs were killed after 10–13 weeks. No overt clinical signs were observed, and only group 4 had slightly lower food conversion rate ( P
