Table 11. Number of ticks submitted monthly to the LSPQ Nb de tiques Among the other species found on our pets, Rhipicephalus sanguineus purportedly transmits Ehrlichia canis, Babesia canis, and other pathogenic agents, while Dermacentor variabilis is considered the main vector of Rickettsia rickettsii, the etiologic agent of Rocky Mountain spotted fever. The other species seem to have only minor importance as vectors of pathogenic agents. All the species of ticks found here have a similar development cycle. They eat only three meals in their lifetime, each on a different animal, and the food they ingest during each of these meals helps the next moult or egg laying after the female’s third meal. They climb onto an animal and can take some time to get a suitable place before they bite and start injecting their saliva and sucking blood. The meal lasts 3 to 14 days, and the ticks detach only at the very end of the meal, at which point they fall to the ground. The sated female will use the food in preparation for laying hundreds of eggs, which will take place a few days later. Due to their method of feeding, which takes them from one animal to another, and since ticks inject a large amount of saliva during their meals in order to get rid of the fluids that were ingested, there is a strong potential for transmission of pathogenic agents. 2.5 Zoonotic species 450 400 350 300 250 200 150 100 50 0 1 2 3 4 5 6 7 8 9 10 11 12 One important argument for controlling parasites in our pets is the fact that the most frequently encountered species are transmissible to humans. Too often, this is unrecognized or ignored, but we should keep it in mind, especially knowing that children are particularly at risk for infection, and since there are more and more people whose immune systems have been weakened by various diseases. 14 Mois

Identifying such infections proves challenging in most cases, and the lack of knowledge on the part of most human health specialists is a major obstacle. Regular consultations with the Diagnostic Laboratory Service suggest that zoonotic infections are quite common, despite the fact that most people, including veterinarians, are under the impression that they are rare. Such cases are simply misidentified or wrongly attributed to some other cause. We can use the case of toxocariosis to illustrate the extent of the problem. Only a few cases of human toxocaral infection have been reported in Canada (Table 8), which seems to have reassured certain specialists (Fanning et al., 1981). However, the 15
