Despite the global distribution of the brown dog tick, Rhipicephalus sanguineus (Latreille, 1806) sensu lato (s.l.), limited information exists about their identity from the Arabian Peninsula. Ticks from free roaming urban dogs and dromedary camels in Riyadh, Saudi Arabia were morphologically identified, confirmed with scanning electron microscopy and characterised at mitochondrial DNA (cox1, 12S rDNA and 16S rDNA). A total of 186 ticks were collected from 65 free roaming dogs (n = 73) and 84 dromedary camels (n = 113). Morphologically, 5.9% (11/186) were R. sanguineus s.l. and Hyalomma spp. (93.5%, 174/186). From within R. sanguineus s.l., the presence of Rhipicephalus cf. camicasi Morel, Mouchet et Rodhain, 1976 (1 dog, 2 camels) and Rhipicephalus turanicus Pomerantsev, 1936 (1 camel) is reported. The examined R. cf. camicasi form a sister group to R. sanguineus s.l. tropical lineage at all DNA markers. Dogs were parasitised by Hyalomma dromedarii Koch, 1844 (n = 59), Hyalomma impeltatum Schulze et Schlottke, 1930 (n = 1), Hyalomma excavatum Koch, 1844 (n = 2), Hyalomma turanicum Pomerantsev, 1946 (n = 1) and Hyalomma rufipes Koch,1844 (n = 1). DNA from dog blood (n = 53) from Riyadh confirmed a low prevalence of canine vector-borne pathogens that does not exceed 5.7% for Babesia spp., Mycoplasma spp., Anaplasma platys, Hepatozoon canis and Ehrlichia canis using multiplexed tandem PCR (MT-PCR) and diagnostic PCR. Low prevalence of R. sanguineus s.l. on dogs likely contributed to the low level of canine vector-borne pathogens in Saudi Arabia. We demonstrate that dogs in the central Arabian Peninsula are more commonly parasitised by Hyalomma spp. than R. sanguineus s.l.

La ehrlichiosis monocítica canina (EMC) es una enfermedad causada por la bacteria intracelular obligada Ehrlichia canis (Rickettsiales, Anaplasmataceae). La EMC es de importancia en salud animal por ser considerada de alta mortalidad en caninos domésticos, con distribución mundial; con síntomas inespecíficos como fiebre alta, depresión, letargia, anorexia y signos clínicos como linfoadenomegalia, esplenomegalia y trombocitopenia con tendencia hemorrágica, por lo que su diagnostico es un desafío en el entorno clínico. Ehrlichia canis es transmitida a un hospedador susceptible por ninfas y adultos de la garrapata Rhipicephalus sanguineus sensu lato. El taxón R. sanguineus s.l. representa un complejo de especies asociadas a caninos domésticos con distribución cosmopolita y particularmente en la región Neotropical se reconocen dos linajes: tropical y templado. El linaje templado, que representa a R. sanguineus sensu stricto, siendo el límite geográfico que separa ambos linajes una zona ecotonal situada entre 24 ° y 25 ° de latitud sur. En condiciones experimentales, R. sanguineus s.s. (linaje presente en la región centro de Argentina) demostró no tener competencia vectorial para transmitir E. canis (cepa Jaboticabal, Brasil) pero si R. sanguineus s.l. del linaje tropical. Sin embargo, estudios recientes han determinado molecularmente la infección con E. canis en muestras de sangre de perros con diagnóstico presuntivo de EMC en la provincia de Buenos Aires, dónde prevalece R. sanguineus s.s. Además, poblaciones de R. sanguineus s.l. (LT) y R. sanguineus s.s. de las provincias de Formosa y Buenos Aires, respectivamente, se detectaron naturalmente infectadas con E. canis. El presente informe de caso es el primer reporte de caso confirmado de EMC por E. canis en un canino de la ciudad de Rafaela, Santa Fe, área endémica de R. sanguineus s.s.

“…No I. inopinatus was collected on dogs, and only R. sanguineus s.l. ticks were identified to "group" level since the re-description of R. sanguineus s.s. (Nava et al, 2018) was not yet available at that time. Ticks were pooled by tick species and by biogeographical region of origin (summarized as Northwest, North, Center, Mediterranean, and South).…”

Ticks and Tick-borne Diseases

Studies on tick microbial communities historically focused on tick-borne pathogens. However, there is an increasing interest in capturing relationships among non-pathogenic endosymbionts and exploring their relevance for tick biology. The present study included a total of 1600 adult ticks collected from domestic dogs in 4 different biogeographical regions of Spain. Each pool formed by 1 to 10 halves of individuals representing one specific ticks species was examined by PCR for the presence of Coxiellaceae, Rickettsia spp., Rickettsiales, Wolbachia spp., and other bacterial DNA. Of the pools analyzed, 92% tested positive for endosymbiont-derived DNA. Coxiella spp. endosymbionts were the most prevalent microorganisms, being always present in Rhipicephalus sanguineus sensu lato (s.l.) pools. Rickettsia spp. DNA was detected in 60% of Dermacentor reticulatus pools and 40% of R. sanguineus s.l. pools, with a higher diversity of Rickettsia species in R. sanguineus s.l. pools. Our study reveals a negative relationship of Rickettsia massiliae with the presence of tick-borne pathogens in the same pool of ticks. An additional endosymbiont, 'Candidatus Rickettsiella isopodorum', was only detected in D. reticulatus pools. Data from this study indicate that dogs in Spain are exposed to several endosymbionts. Due to the importance of tick-borne pathogens, characterizing the role of endosymbionts for tick physiology and prevalence, may lead to novel control strategies.
