Abstract Background Camel production in Saudi Arabia is severely affected by various diseases and by inadequate veterinary services. Ticks and tick-borne pathogens (TBPs) represent a major threat to the health of camels consequently affecting 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 Current 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.

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.).

Las enfermedades caninas causadas por protozoarios y transmitidas por garrapatas representan un importante problema en medicina veterinaria. El objetivo del estudio fue detectar molecularmente Hepatozoon spp., Babesia spp. y Theileria spp. en perros clínicamente sanos de distintas regiones de Argentina y analizar la diversidad genética de los hallazgos obtenidos. Se analizaron 163 muestras de ADN de sangre de perros (40 de Ciudad Autónoma de Buenos Aires; 33 de Bahía Blanca, Buenos Aires; 15 de Castelli, Chaco; 27 de Salsipuedes, Córdoba; 40 de Merlo, San Luis; y 8 de San Miguel, Corrientes). Mediante una PCR que amplifica un fragmento variable (460-540 pb) del gen ARNr 18S incluyendo la región V4 de los géneros Hepatozoon, Babesia y Theileria, el 12,1 % (4/33) de los perros de Bahía Blanca (Buenos Aires) resultaron positivos. Las secuencias obtenidas se identificaron como Hepatozoon canis y resultaron filogenéticamente similares a hallazgos en Sudamérica y en el resto del mundo. El estudio de H. canis en Argentina mediante técnicas moleculares de diagnóstico junto con el análisis filogenético resulta de suma importancia para conocer la situación de este patógeno en el país.

Las condiciones propias de un país tropical como Costa Rica representan grandes ventajas para ladistribución y actividad de las garrapatas, así como facilita que exista una serie de hospedadores paraeste tipo de ectoparásitos. Ambos factores inciden en la presentación y prevalencia de enfermedadesvectoriales zoonóticas. En el presente trabajo se presentan los principales resultados obtenidos en lasinvestigaciones realizadas durante los últimos diez años en la Escuela de Medicina Veterinaria, en lascuales se ha determinado la presencia, se ha estimado la prevalencia y se ha establecido la importancia,en la salud pública, de agentes rickettsiales (Ehrlichia spp., Anaplasma spp. y Rickettsia spp.), piroplasmas(Babesia spp., Theileria spp.), y Hepatozoon canis en animales domésticos (caninos, felinos, equinosy ovinos), animales silvestres (mapaches, pizotes, venados cola blanca) y garrapatas de nuestro país.Además, se presentan los resultados obtenidos en un estudio serológico de donadores de sangre; enespecial, la identificación de un nuevo genotipo de Ehrlichia canis hallado en ellos. Finalmente, sediscute sobre la diseminación, transmisión y curso de las diferentes enfermedades, como también sobreel diagnóstico, el tratamiento y los estudios que hacen falta para establecer las medidas de controlapropiadas a adoptar para el control de estas enfermedades en nuestro país.

Climate changes in recent years led to a sharp rise in the tick population and an increase in the number of animals and people with tick-borne infections. The domestic and wild carnivores, especially the dogs, have a huge role for the distribution of ticks in certain areas. In this study 60 ixodid ticks collected from domestic dogs and red foxes from Bulgaria have been investigated for infection with Ehrlichia canis, Hepatozoon canis, Babesia spp., and Rickettsia spp. The results showed that the dogs were infected with two tick species - Rhipicephalus sanguineus (72%) and Ixodes ricinus (28%). The red foxes were infected with only one species - I. ricinus. Out of all R. sanguineus ticks, 43.6% were female and 56.4% male. The opposite was observed for I. ricinus - female specimens (86.7%) were significantly more prevalent than males (13.3%). Similar trend was found out for I. ricinus collected from red foxes - 66.7% of the ticks were female and 33.3% male. Infectious agents were found in 31.7% of the investigated ticks. Ehrlichia spp. was established in 79% and Rickettsia spp. in 21% of the infected ticks. Ehrlichia spp. was found only in ticks collected from dogs. The majority of the ticks infected with Ehrlichia spp. were Rh. sanguineus (93.3%) and only one tick was I. ricinus (6.7%). Four ticks were positive for Rickettsia spp., two were Rh. sanguineus and two - I. ricinus, one of the latter was found on a fox. This is the first report about detection of Ehrlichia spp. in Rh. sanguineus ticks from Bulgaria as well as Rickettsia spp. in I. ricinus ticks collected from red foxes from this country.

Abstract Background Ticks and tick-borne diseases are increasingly recognized as a cause of disease in dogs worldwide. The epidemiology of ticks and tick-transmitted protozoa and bacteria has changed due to the spread of ticks to urban and peri-urban areas and the movement of infected animals, posing new risks for animals and humans. This countrywide study reports information on distribution and prevalence of pathogens in ticks collected from privately-owned dogs in Italy. We analyzed 2681 Ixodidae ticks, collected from 1454 pet dogs from Italy. Specific PCR protocols were used to detect i) Piroplasms of the genera Babesia and Theileria , ii) Gram-negative cocci of the family Anaplasmataceae and iii) Borrelia burgdorferi sensu lato. Sequencing of positive amplicons allowed for species identification. Results Babesia / Theileria spp. DNA was detected in 435 homogeneous tick-pools (Minimum Infection Rate (MIR) = 27.6%; 95% confidence interval (CI) = 25.4-29.8%) with higher prevalence in Ixodes ricinus and Rhipicephalus sanguneus group. The zoonotic B. venatorum was the most prevalent species (MIR = 7.5%; 95% CI = 6.3-9.0%). Anaplasma and Ehrlichia species were detected in 165 tick-pools (MIR = 10.5%; 95% CI = 9.3-11.8%) and specifically, A. phagocytophilum was identified with MIR = 5.1% (95% CI = 4.1-6.3%). Borrelia burgdorferi s.l. and B. afzelii were detected with MIR = 0.4% (95% CI = 0.2-0.8%) and MIR = 0.3% (95% CI 0.1-0.7%) respectively. Conclusions Zoonotic pathogens B. venatorum and A. phagocytophilum were the most frequently detected in ticks collected from privately-owned dogs which might be used as markers of pathogens presence and distribution.
