Ticks identified as Rhipicephalus sanguineus (Latreille, 1806) have been recorded in Australia since 1896. It is now recognized that ticks identified as R. sanguineus belong to different lineages. Recently, the so‐called temperate lineage has been redescribed as R. sanguineus sensu stricto with a designated neotype. In Australia, the evidence suggests that only R. sanguineus sensu lato tropical lineage exists. We present a genetic evaluation of R. sanguineus sensu Roberts (1965) from museum material that was evaluated or identified by Roberts. We evaluated 12 museum specimens collected between 1913 and 1964, from various locations around Australia at the molecular level. DNA isolation was successful for 4/12 specimens. All four museum specimens were 100% identical to each other and to the reference R. sanguineus s.l. tropical lineage. Measurements of morphologically significant structures for male and female museum and contemporary tick specimens were obtained. The morphologically significant structures revealed there was no significant difference (ANOVA, P > 0.05) between these groups of male and female ticks. This study updates and supplement the comprehensive descriptions provided by Roberts (1965), which genetically belong to R. sanguineus s.l. tropical lineage.

“…This could be due to the fact that the vectors, R. sanguineus and I. ricinus, are widely distributed throughout the Spanish geography (61). Regarding R. sanguineus, this tick is the most common tick found in dogs in Spain (61)(62)(63) and it has been detected across the country, which could justify the homogeneous distribution found in this study (61,64). The prevalences obtained from studies previously carried out in Galicia, Castilla, and Leon or Madrid on both bacteria (9, 65-68) were lower than the results obtained in this study, except in the case of Castilla and Leon (19.2% for E. canis) (66).…”

Current Distribution of Selected Vector-Borne Diseases in Dogs in Spain

Currently, climate change, modifications of landscapes and habitats due to human activities, as well as an increase in the movement of reservoirs and new species of competent vectors, have contributed to the spread of canine vector-borne diseases. These are mostly emerging and neglected diseases, some of them with zoonotic potential. Therefore, the objective of this study was to assess the prevalence and distribution of four major canine vector-borne diseases (Dirofilaria immitis, Leishmania infantum, Anaplasma spp., and Ehrlichia canis) in Spain. Between September 2018 and February 2020, blood was sampled from 4643 client-owned dogs from 111 veterinary clinics from the 17 autonomous communities of Spain. All samples were tested for the detection of D. immitis antigens, and for antibodies against L. infantum, Anaplasma spp. and E. canis. Of the studied dogs, 22.14% were positive for one or several diseases while the prevalence was 6.25% (CI: 5.59-6.98) for D. immitis, and the seroprevalences were 10.36% (CI: 9.52-11.27) for L. infantum, 5.06% (CI: 4.47-5.73) for Anaplasma spp., and 4.26% (CI: 3.72-4.88) for E. canis. Co-infections by two and three vector-borne diseases were reported in 13% and 2% of the infected dogs, respectively. The studied vector-borne diseases are widely distributed throughout the Spanish geography, being observed and expanding northward in the case of D. immitis and L. infantum. The results point to an insufficiency of preventive measures to avoid the infection, and the need of the implementation of awareness campaigns among veterinarians and owners. Furthermore, a close collaboration between veterinarians, physicians and health authorities would be necessary for such zoonotic vector-borne diseases.

Two lineages of brown dog ticks (Rhipicephalus sanguineus sensu lato (s.l.), Latreille [Acari: Ixodidae]) have been described in North America: temperate and tropical. To characterize the distribution of these lineages across this region and evaluate seasonal activity, a 12S rRNA mitochondrial gene fragment was sequenced from R. sanguineus s.l. collected from hundreds of dogs and cats from different locations across 25 of the 50 states from 2018 to 2021. Infestations with temperate lineage predominated (78.5%) and were identified on pets from 20 states, with most (83.5%) from areas with annual mean daily average temperature <20°C. Tropical lineage submissions were less common (19.3%), submitted from 15 states, and most (80.0%) tropical lineage ticks were from areas with an annual mean daily average temperature >20°C. Although travel history was not obtained for all dogs, when tropical lineage infestations were found in colder regions, follow up conversations with veterinarians suggested some of these infestations may have resulted from recent travel of dogs. A limited number (2.2%) of dogs from Arizona and Texas were co-infested with both lineages. Both temperate and tropical lineage ticks were collected from pets in every month of the year. Temperate lineage infestations were primarily collected March through August while tropical lineage infestations were more often collected June through November. These data confirm at least two lineages of R. sanguineus s.l. are present in the United States, each predominating in distinct, overlapping geographies, and suggest that peak activity of each lineage occurs at different times of the year.
