Background: Ticks and fleas are considered amongst the most important arthropod vectors of medical and veterinary concern due to their ability to transmit pathogens to a range of animal species including dogs, cats and humans. By sharing a common environment with humans, companion animal-associated parasitic arthropods may potentially transmit zoonotic vector-borne pathogens (VBPs). This study aimed to molecularly detect pathogens from ticks and fleas from companion dogs and cats in East and Southeast Asia. Methods: A total of 392 ticks and 248 fleas were collected from 401 infested animals (i.e. 271 dogs and 130 cats) from China, Taiwan, Indonesia, Malaysia, Singapore, Thailand, the Philippines and Vietnam, and molecularly screened for the presence of pathogens. Ticks were tested for Rickettsia spp., Anaplasma spp., Ehrlichia spp., Babesia spp. and Hepatozoon spp. while fleas were screened for the presence of Rickettsia spp. and Bartonella spp. Result: Of the 392 ticks tested, 37 (9.4%) scored positive for at least one pathogen with Hepatozoon canis being the most prevalent (5.4%), followed by Ehrlichia canis (1.8%), Babesia vogeli (1%), Anaplasma platys (0.8%) and Rickettsia spp. (1%) [including Rickettsia sp. (0.5%), Rickettsia asembonensis (0.3%) and Rickettsia felis (0.3%)]. Out of 248 fleas tested, 106 (42.7%) were harboring at least one pathogen with R. felis being the most common (19.4%), followed by Bartonella spp. (16.5%), Rickettsia asembonensis (10.9%) and "Candidatus Rickettsia senegalensis" (0.4%). Furthermore, 35 Rhipicephalus sanguineus ticks were subjected to phylogenetic analysis, of which 34 ticks belonged to the tropical and only one belonged to the temperate lineage (Rh. sanguineus (sensu stricto)).

Conclusion: Our data reveals the circulation of different VBPs in ticks and fleas of dogs and cats from Asia, including zoonotic agents, which may represent a potential risk to animal and human health.

DO) 3 33Abstract 34 Ticks and fleas are considered amongst the most important arthropod vectors of medical and 35 veterinary concern due to their ability to transmit pathogens to a range of animal species including 36 dogs, cats and humans. By sharing a common environment with humans, companion animal-37 associated parasitic arthropods may potentially transmit zoonotic vector-borne pathogens (VBPs). 38 This study aimed to molecularly detect pathogens from ticks (n = 392) and fleas (n = 248) collected 39 from companion dogs and cats in East and Southeast Asia. Of the 392 ticks tested, 37 (9.4%) scored 40 positive for at least one pathogen with Hepatozoon canis being the most prevalent (5.4%), followed 41 by Ehrlichia canis (1.8%), Babesia vogeli (1%), Anaplasma platys (0.8%) and Rickettsia spp. (1%) 42 [including Rickettsia sp. (0.5%), Rickettsia asembonensis (0.3%), Rickettsia felis (0.3%)]. Out of 43 248 fleas tested, 106 (42.7%) were harboring at least one pathogen with R. felis being the most 44 common (19.4%), followed by Bartonella spp. (16.5%), Rickettsia asembonensis (10.9%) and 45 Candidatus Rickettsia senegalensis (0.4%). Furthermore, 35 Rhipicephalus sanguineus sensu lato 46 ticks were subjected to phylogenetic analysis, of which 34 ticks belonged to the tropical and only 47 one belonged to the temperate lineage (Rh. sanguineus sensu stricto). Our data reveals the 48 circulation of different VBPs in ticks and fleas of dogs and cats from Asia, including zoonotic 49 agents, which may represent a potential risk to animal and human health.50 51 Author summary 52 Ticks and fleas are among the most important vectors of pathogens infesting many animal species 53 including humans worldwide. Although a number of vector-borne pathogens have been detected in 54 dogs and cats from East and Southeast Asia, investigation in ticks and fleas collected from them are 55 scant. In order to provide an overview of the pathogens circulating in ticks and fleas from 4 56 companion dogs and cats in Asia, ticks (n = 392) and fleas (n = 248) were collected from privately-57 owned dogs and cats from China, Taiwan, Indonesia, Malaysia, Singapore, Thailand, Philippines 58 and Vietnam and molecularly screened for the presence of pathogens. Overall, multiple pathogens 59 were found in ticks (i.e., Babesia vogeli, Hepatozoon canis, Ehrlichia canis, Anaplasma platys and 60 Rickettsia spp.) and fleas (i.e., Rickettsia spp. and Bartonella spp.) from the sampling areas. Of the 61 ticks tested, 9.4% scored positive for at least one pathogen and of fleas 42.7% harbored at least one 62 pathogen with Rickettsia felis being the most common (19.4%). Overall, of the detected pathogens, 63 R. felis stood out as the most important due to its zoonotic potential. The result of this study should 64 increase awareness among pet owners and veterinary practitioners regarding the importance of ticks 65 and fleas, and their transmitted pathogens. 66 67 68 Vector-borne diseases are caused by bacteria, viruses, protozoa and helminths transmitted by 69 arthr...
