Arthropods Specific to dogs Specific to cats In both dogs and cats Trichodectes canis Felicola subrostratus Linognathus setosus 6 Ctenocephalides felis Sarcophagidae (myiasis) Calliphoridae (myiasis) Cuterebra spp. Ixodes scapularis Ixodes cookei Ixodes muris Rhipicephalus sanguineus Dermacentor variabilis Amblyomma americanum Notoedres cati Sarcoptes scabiei Demodex canis Demodex cati Otodectes cynotis Cheyletiella yasguri Cheyletiella blackei Pneumonyssus caninum 2. Prevalence of the main species of parasites Trombiculidae First, it is important to know what the prevalence of the parasite species is in our region. A few study results of the more common species were published in the past, and they provide valuable information. For more recent data, we will use those obtained by Dr. Brigitte Guay when working on her master’s degree and those obtained at the Diagnostic Laboratory Service of the Faculty of Veterinary Medicine in Saint-Hyacinthe. 2.1 Study results published in Canada The vast majority of the prevalence studies of canine parasites were published more than 25 years ago, specifically, between 1974 and 1979. Another was published in 1950. The last two date back to 1986 and 1987. However, their results have little to do with our current situation, since one of these studies was carried out in the far north of Québec, the other carried out on samples taken in a recreational area. The data from these studies are presented in the following table:

Researchers have compiled 54 studies covering some 42,000 dogs and obtained a mean of 15,2% of dogs excreting Toxocara eggs, although the range was 0 to 93% (Glickman and Schantz, 1981). However, recent reports from university laboratories show a sharp decrease in these figures. Table 4.
