Few data are available in the literature on the dermatological consequences and treatment of Neotrombicula autumnalis infestation in dogs and cats. In this study, 15 dogs naturally infested with Neotrombicula were affected with moderate to severe pruritic dermatitis. The dermatitis resolved with successful treatment of the parasitic infestation. In 14 dogs, treatment using a topical permethrin-pyriproxyfen combination (pump-spray or 'line-on') was effective within one to three weeks. Two applications were necessary in four dogs. Careful follow-up was conducted in all cases. Statistical analysis was performed to assess the impact of treatment on the parasite population and clinical signs over the three-week study period.

Administration of the ivermectin-praziquantel paste appears to be safe in pregnant mares and their foals.

Five groups of 20 weaned beef calves were injected subcutaneously with either an ivermectin, a doramectin, an abamectin long-acting formulation, an ivermectin long-acting formulation or a saline control, at turnout and 60 and 120 days later. The animals grazed the same pasture and were sampled and weighed at turnout and 30, 60, 90, 120, 150 and 180 days later. At turnout the mean bodyweights of all the groups were similar and faecal culture showed that they had a mixed strongyle infection of Cooperia, Haemonchus, Ostertagia, Oesophagostomum and Trichostrongylus species. After 180 days, the mean bodyweight gains of each group were respectively 62.1 kg, 102.2 kg, 106.4 kg, 107.3 kg and 110.1 kg for the control, ivermectin, doramectin, ivermectin long-acting and abamectin long-acting groups. All the products significantly improved the weight gains of the cattle, and significantly reduced their faecal egg counts.
