Figure 1From: Moxidectin steady state prior to inoculation protects cats from subsequent, repeated infection with Dirofilaria immitis Mean levels of moxidectin (μg/L) prior to and during repeated infection with Dirofilaria immitis . Cats were treated with 10% imidacloprid-1% moxidectin on study days −84, −56, −28, and 0. Third-stage larvae of D. immitis (n = 25) were inoculated on days 7, 14, 21, and 28, 1 – 4 weeks after the final treatment was administered.Back to article page
