Epidemiology, genetic divergence and acaricides of Otodectes cynotis in cats and dogs

Otodectes cynotis mite is a common parasite of cats and dogs, survives in the ear canal and causes otitis externa, itching and severe complications. The microscopic examination of ear swabs, skin scraps and faecal samples of 289 cats and 223 dogs revealed that mono-specific and mixed infestations of...

Description
Summary:Otodectes cynotis mite is a common parasite of cats and dogs, survives in the ear canal and causes otitis externa, itching and severe complications. The microscopic examination of ear swabs, skin scraps and faecal samples of 289 cats and 223 dogs revealed that mono-specific and mixed infestations of Otodectes cynotis in cats were (24.56%) and(6.57%) while in dogs were (7.17%) and (4.48%) respectively. The highest rate of infestation was in young cats and the lowest was in elder dogs. The mixed infestations were found in combination with Sarcoptes, Demodex, Dermatophytes, Ticks, Fleas, Ascarids, Dipylidium and Isospora. The RAPD-PCR proved the genetic divergence between cat and dog isolates whereas they are morphologically similar. Selamectin-pour on, Doramectin-subcutaneous injection and Ivermectin-Ear drops were evaluated two weeks post treatment. The rate of success in cats were (96.66%) ,(90.00%) and (83.33%) and in dogs were (77.77%), (75.00%) and (66.66%) respectively. It is concluded that Selamectin pour on is the best acaricide against Otodectes cynotis in both cats and dogs. It is also needed to prepare a vaccine in the future to prevent the infestation with Otodectes cynotis and its complications.
