Adaptation of Haemonchus contortus to condensed tannins: can it be possible?

The in vitro anthelmintic (AH) effect of Acacia pennatula, Lysiloma latisiliquum, Piscidia piscipula and Leucaena leucocephala tannin rich extracts on three Mexican strains of Haemonchus contortus L 3 larvae was evaluated. Water/acetone extracts were obtained from the fodder of A. pennatula, L. lati...

Water/acetone extracts were obtained from the fodder of A. pennatula, L. latisiliquum, P. piscipula and L. leucocephala collected in the vegetation of Yucatan, Mexico.
