Abstract

Dogs and cats play an important role as reservoirs of vector-borne pathogens, yet reports of canine and feline vector-borne diseases in Saudi Arabia are scarce. Blood samples were collected from 188 free-roaming dogs and cats in Asir (70 dogs and 44 cats) and Riyadh (74 dogs), Saudi Arabia. The presence of Anaplasma spp., Bartonella spp., hemotropic Mycoplasma spp., Babesia spp., and Hepatozoon spp. was detected using a multiplex tandem real-time PCR. PCR-positive samples were further examined with specific conventional and real-time PCR followed by sequencing. Dogs from Riyadh tested negative for all pathogens, while 46 out of 70 dogs (65.7) and 17 out of 44 cats (38.6) from Asir were positive for at least one pathogen. Positive dogs were infected with Ana-plasma platys (57.1), Babesia vogeli (30), Mycoplasma haemocanis (15.7), and Bartonella henselae (1.4), and cats were infected with Mycoplasma haemofelis (13.6), Candidatus Mycoplasma haemo-minutum (13.6), B. henselae (9.2), and A. platys (2.27), all of which are reported for the first time in Saudi Arabia. Co-infection with A. platys and B. vogeli was detected in 17 dogs (24.28), while coinfections were not detected in cats. These results suggest that effective control and public aware-ness strategies for minimizing infection in animals are necessary. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.
