Abstract Background: Camel production in Saudi Arabia is severely affected by various diseases and by inadequate veterinary services. Ticks and tick-borne pathogens (TBPs ) affect the health and wellbeing of camels consequently diminishing their productivity and performances. In addition, camels may act as hosts for TBPs (e.g. Anaplasma phagocytophilum ) causing diseases in humans. The current study aimed to determine the prevalence of ixodid ticks and molecularly investigate the associated pathogens in camels from Saudi Arabia. Methods: Blood and tick samples were collected from camels ( n = 170) in Riyad Province of Saudi Arabia. Ticks were morphologically identified, and blood of camels were molecularly screened for apicomplexan (i.e. Babesia spp . , Theileria spp., Hepatozoon spp.) and rickettsial parasites (i.e. Ehrlichia spp. and Anaplasma spp.). Results: Of the 170 camels examined, 116 (68.2%; 95% CI: 60.9–75.1%) were infested by ticks with a mean intensity of 2.53 (95% CI: 2.4–2.6). In total of 296 ticks collected, Hyalomma dromedarii was the most prevalent (76.4%), followed by Hyalomma impeltatum (23.3%) and Hyalomma excavatum (0.3%). Of the tested animals, 13 (7.6%; 95% CI: 4.3–12.8%) scored positive to at least one TBP, with Anaplasma platys (5.3%; 95% CI: 2.7–9.9%) being the most prevalent species, followed by Anaplasma phagocytophilum , Anaplasma sp., Ehrlichia canis and Hepatozoon canis (0.6% each; 95% CI: 0.04–3.4%). None of the camels were found to be co-infected with more than one pathogen. All samples tested negative for Babesia spp. and Theileria spp. Conclusions: The present study reveals the occurrence of different tick species and tick-borne pathogens in camels from Saudi Arabia. Importantly, these camels may carry A. phagocytophilum and A. platys , representing a potential risk to humans.

Ticks are still considered a major cause of zoonotic diseases most especially to dogs and other related animals. This study was conducted to assess the ticks infestation of dogs in Runjin Sambo area Sokoto. The sample was collected using hand picking and hair brushing method with the assistance of dog owners. A total of sixty dogs were randomly selected in four different sub areas in Runjin Sambo. The locality, sex and age of the dogs were noted. The ticks species were identified in the entomology laboratory using key devices. Four species of ticks namely, Amlyomma variegatum, Rhipicephalus pulchellus, Boophilus decolaratus and Hyalomma excavatum were identified. The 45 (75%) of dogs were found infected with prevalence of 11.67%, 21.67%, 25.00% and 16.67% in the four sub-areas respectively. The prevalence rate of infection was 31.67% in male dogs and 43.33% in female dogs. Similarly 55.00% and 20.00% in adult and puppy dogs respectively.  Tick infestation of dogs seems to be due to poor and unhygienic condition of the dogs and can be reduced by proper sanitation, improve hygiene and health education.
