Appendix A Complete list of 594 pathogens identified in canines categorized by the following taxonomical groups: bacteria, ectoparasites, fungi, helminths, protozoa, rickettsia and viruses. Pathogens categorized as zoonotic/sapronotic/anthroponotic have been bolded; sapronoses are specifically denoted by a ❖. If the dog is involved in transmission, maintenance or detection of the pathogen it has been further underlined. Of these, if the pathogen is reported in dogs in Canada (Tier 1) it has been denoted by an *. If the pathogen is reported in Canada but canine-specific reports are lacking (Tier 2) it is marked with a C (see also Appendix C). Finally, if the pathogen has the potential to occur in Canada (Tier 3) it is marked by a D (see also Appendix D).
