Conteúdo: | The interaction between ivermectin-resistant and ivermectin-sensitive nematodes and the effect of this anthelmintic on the hematological status of naturally infected goats was assessed using 36 animais. Of these animaIs, 12 were infected by ivermectin-sensitive gastrointestinal nematodes of the superfamily Trichostrongyloidea (G1s e G1s) 12 were infected by ivermectin-resistant nematodes (G2r e G2r) and 12 uninfect goats (G3np). Six infected goats of each group (G1sm e G2rm) received oral ivermectin aI the dose of 200mg/kg, while six were used as controIs (G1sc e G2rc). Blood and fecal samples were collected on the day of medication (day zero), at seven, and at 14 days thereafter. The erythrocyte count and hematocrit levels in goats infected by sensitive strains of Haemonchus was greater than that of the group infected by a resistant strain. These values are lower in comparison to those observed in uninfected goats. The increase in lhe number of eggs per gram of feces, regardless of lhe strain, is inversely related to lhe hematocrit level. The use of ivermectin did not significantly change lhe hematological parameters of goats.
