Epizootic features of pets’ sarcoptoidoses and therapeutic efficiency of iver-mectin

Keywords: sarcoptoidoses, cats, rodents, ivermectin, intensity of invasion, intensefficiency of drugs


In the article the results of studies of epizootic characteristics, clinical course, diagnosis criteria of pets’ sarcoptoides, as well as evaluating the therapeutic efficacy of ivermectin in the fight against scabious diseases are presented. It is established that sarcoptoides among pets are mostly cats, home decorative rabbits, Guinea pigs, rats. Largely that do not meet hygienic standards contribute to contamination of animal welfare. Among the pathogens of pets’ sarcoptoidoses there are whole range, namely Notoedres cati causes scabies names notoedrosis; supracutaneous mite Psoroptes cuniculi striking in rodents, causing them the development of parasitic otitis, and carpet mite Otodectes cynotis is the cause of otodectosis in cats. Otodectosis in cats (31%) is most widespread. This is due to commensals of the pathogen and the constant presence of it in the external auditory canal. The rest of the diseases takes from 5 to 10% of the extensiveness of the invasion. Notoedrosis of cats is a highly contagous disease and more common in cats who have come into contact with stray animals and may have contracted through direct contact. Parasitic otitis in rodents, caused by Psoroptes cuniculi, develop in individuals that are kept separately and were not part of a collective of animals. Likely, the main contagion happened from mothers, and in further animals were carriers of parasites. Under favorable conditions, the increased development of ticks led to the emergence of the disease. Scabies diseases were accompanied by the development of dermatitis of varying severity, itching with scratches and abrasions. The clinical picture is quite characteristic, but the basis for diagnosis is the detection and identification of the pathogen, as well as the calculation of the intensity of the invasion. To combat sarcoptoidosis pathogens, parenteral administration of ivermectin solutions of 1% and 0.1% was applied twice at 7-day intervals at a dose of 0.03 ml/kg of 1% solution and 0.3 ml/kg of 0.1% solution. 7 days intensefficiency of drugs accounted for 69–85% and for 14 – 95–100%. The most effective drug was to fight Psoroptes cuniculi and Notoedres cati. Less intensefficiency of the drug in the fight against Otodectes cynotis may be associated with the biology of the mites and its commensals to the external auditory canal of cats.
