ABSTRACT

 

Khayatnouri MH, Garedaghi Y., Effect of pour on ivermectin on natural Toxascaris leonina infestations in street dogs, Onl J Vet Res., 27 (7): 415-419, 2023. Authors determined effect of pour on ivermectin on natural Toxascaris leonina infestations in dog. After confirming infestation by adult worms, 0.5 mg kg Ivermectin pour-on was administered to 60 street dogs. Feces were subjected to Willis and MacMaster tests for T leonina eggs at days 1, 7, 21 and 28 days after treatment. We found 13 or 22% of 60 dogs tested for eggs to be infested by Toxascaris leonina with mean egg count of 137. Results showed that prevalence of Toxascaris leonina infestations was 21.7%. Treatment with pour on ivermectin, reduced egg counts 21.2% at day, 43.1 by 7 days, 88.3 by 21 days and 98.5% by 28 days. Contact time of parasite with ivermectin rather than its dose may be more effective justifying slow release delivery in dogs.
