Anthelmintic efficacy of milbemycin D against Toxocara cati and Ancylostoma tubaeforme in domestic cats.
Anthelmintic efficacy of milbemycin D was evaluated against Toxocara cati and Ancylostoma tubaeforme in domestic cats. Twelve cats naturally infected with each nematode species were allocated among 2 groups of 6 animals each, and milbemycin D was orally administered to the 2 groups of cats in doses of 0.05 mg/kg and 0.1 mg/kg body weight, respectively. In all the cats infected with T. cati, fecal egg counts decreased followed by their disappearance from the feces and 2-35 worms were excreted into the feces after the medication in both doses of 0.05 mg/kg and 0.1 mg/kg. At postmortem of these medicated groups, no worms were detected from 4 cats of each group, but 1 and 2 immature worms were recovered from the other 2 cats respectively. In the cats infected with A. tubaeforme, fecal egg counts decreased followed by the disappearance from the feces and 2-62 worms were excreted into the feces in all the cats of the 2 groups, no nematodes remaining at postmortem. These results indicate that milbemycin D is fully effective against T. cati and A. tubaeforme in cats in a dose of 0.05-0.1 mg/kg.
