The aim of this study was to identify the species and parasitic indices of ticks. A flock of 57 individuals (sheep, goats, cattle and dogs) in southern Algeria was studied from March 2019 to February 2020 during monthly visits. A total of 2544 ticks were collected by examining the entire body of the animal. Two tick species were identified: Hyalomma dromedarii (2430 ticks) and Rhipicephalus sanguineus sensu lato (114 ticks). The first species had annual activity and consisted only of adults, while the second species had spring and summer activity and contained both adults and nymphs. At the annual level, the prevalence of infestation, abundance, and intensity were 38.60%, 44.63 and 115.64 ticks per animal, respectively. At the monthly level there were species specific fluctuations, with a peak in activity in September.

Rhipicephalus Sanguineus Sensu Lato

Rhipicephalus sanguineus, the brown dog tick, is responsible for maintaining and transmitting various pathogens, both in animals and human beings, and it is of great sanitary importance. This communication reports the first occurrence of Rhipicephalus sanguineus sensu lato parasitizing Rattus norvegicus in the state of Rio Grande do Sul, Brazil, and it is also the first record of this tick species parasitizing Rattus rattus in Brazil. The rodents were captured from the port area, located in the city of Pelotas, Rio Grande do Sul, Brazil. We collected 6 larvae of this tick species from 2 male R. rattus individuals, and 3 larvae from 2 female R. norvegicus individuals; parasitized specimens of both rodent species were captured from different sites within the experimental area. This record broadens the number of Rhipicephalus sanguineus sensu lato hosts in urban areas, indicating the need for continued monitoring on population density for both R. sanguineus and synanthropic rodents.

Abstract The present study aimed to contribute towards identification and registration of tick species that parasitize dogs in rural and urban areas of three mesoregions of Paraná, southern Brazil, and to estimate the rate of occurrence of each species. Fifty-six dogs with ticks living in three mesoregions: Metropolitana de Curitiba (MC), Centro Oriental (COP) and Centro Sul Paranaense (CSP), were used in the study. From these 56 dogs, 253 ticks were collected and were identified and morphologically characterized according to the species. Among all the ticks, 69.6% were identified as belonging to the species Rhipicephalus sanguineus sensu lato (s. l.); 28.1% as Amblyomma aureolatum and 2.4% as Amblyomma ovale. Among the dogs in MC that were evaluated, 57.7% were parasitized by R. sanguineus s. l., 38.5% by A. aureolatum and 3.8% by A. ovale; while in COP, 72.4% of the dogs were parasitized by A. aureolatum and 27.6% by R. sanguineus s. l.. In CSP, one tick was obtained, which was identified as A. aureolatum.

Monthly total body tick collections from 13-20 camels were conducted for 2 consecutive years (2000-2001) in Northern Sudan. Tick populations were correlated with locality, season, predeliction site, sex and coat colour. Hyalomma dromedarii was found to be the predominant (89 %) tick species infesting the camels. Other tick species found in very low numbers were Hyalomma impeltatum (7.7 %), Hy alomma anatolicum anatolicum (3.3 %), Hyalomma truncatum (0.29 %), Hyalomma marginatum rufipes (0.25 %), Rhipicephalus praetextatus (0.30 %) and Rhipicephalus sanguineus group (0.09 %). Nymphs of the genus Hyalomma were collected in significant numbers. Adult ticks significantly preferred to attach to the lower parts of the camel's body for feeding while the nymphs preferred the back of the animal.

In Mexico, the distribution and the presence of pathogenic genospecies of B. burgdorferi in dogs and their ticks has not been extensively investigated. The study of canine borreliosis is acquiring greater relevance, since the dog is considered to be an important sentinel for pathogens pertaining to the complex Borrelia burgdorferi sensu lato; in addition, dogs could be playing a key role in the spread of ticks from forested areas into the domestic environment. This study aimed to detect and estimate the prevalence of B. burgdorferi s.l. in dogs and their ticks in two rural communities of Yucatán, Mexico. In each community, 50 houses were visited, where 144 blood samples from dogs were studied by puncture of the saphenous vein, as well as the collection of their ticks. To detect the presence of B. burgdorferi s.l. in these samples, the conserved gene flaB, p66 and ospC were PCR amplified. A total of 144 dog blood samples, and 846 of ticks were obtained from the examined animals. Considering tick species, Rhipicephalus sanguineus sensu lato (786 / 846) was common, while Ixodes affinis (33 / 846), and Amblyomma mixtum (27 / 846) resulted less frequent. As per gene conservation, the prevalence of B. burgdorferi in canine blood was 17.3 % (25 / 144) to flaB, 12.50 % (18 / 144) for p66 and 1.38 % (2 / 144) for the ospC gene. Within the analyzed ticks, R. sanguineus s.l. had a prevalence of 0.89 %, A. mixtum 5.88 % and I. affinis 15.15 %, being this last species the one that presented higher prevalence. Two dogs and their ticks I. affinis were positive to the flaB gene. Only a tick R. sanguineus s.l. was positive to the gene p66 and no tick species was positive the ospC gene. This study confirmed the existence of B. burgdorferi s.l. in dogs and their ticks in rural communities of Yucatán, Mexico. The detection of Borrelia in dogs may be an important criterion for the evaluation of the risk of borreliosis in humans, since the dog can be used as an epidemiological indicator for the identification of new outbreaks of this disease.

Rapid Urbanization

Ticks are important arthropod vectors that serve as reservoirs of pathogens. Rapid urbanization and changes in animal breeding practices could be causing a rise in tick burden on animals. Studies on tick distribution on livestock and tick molecular diversity from the United Arab Emirates (UAE) are limited. The aim of this study was to (i) provide molecular and morphological identification of tick species, (ii) compare tick infestation between different hosts, (iii) compare tick infestation in relation to the sex of the host, and (iv) assess the prevalence of tick species on hosts. A total of 5950 ticks were collected from camels (4803 ticks), cows (651 ticks), goats (219 ticks), and sheep (277 ticks). Ticks were identified based on morphological characters at the species level using taxonomic keys. In addition, Polymerase Chain Reaction (PCR) amplification of the cytochrome oxidase subunit 1 (cox1) and 16S rRNA mitochondrial genes was used to identify ticks. Four species were confirmed based on molecular and morphological characterization, namely, Hyalomma dromedarii, Hyalomma anatolicum, Rhipicephalus sanguineus, and Amblyomma lepidum. Hyalomma dromedarii (94.3%) was the most abundant species, followed by H. anatolicum (32.8%). Camels were heavily infested (94%) with ticks as compared to cows (38%), sheep (37%), and goats (14%). Widespread occurrence of these four tick species in the UAE poses a risk of spreading tick-borne pathogens wherever the conditions of infection prevail.

Increased human mobility elevates the risk of exposure of companion animals travelling with their owners or imported from other regions to tick attacks. In this study, we highlight the potential role of dogs and cats taken for tourist trips or imported animals in the spread of ticks and tick-borne pathogens. The Rhipicephalus sanguineus tick, which is a vector of numerous pathogens causing diseases in animals and humans, is imported most frequently from endemic areas to many European countries. Additionally, alien tick species with high epizootic and epidemiological importance can be imported on dogs from other continents. Companion animals play an even greater role in the spread of autochthonous tick species and transmission of tick pathogens to other animals and humans. Although the veterinary and medical effects of the parasitism of ticks carried by companion animals travelling with owners or imported animals are poorly assessed, these animals seem to play a role in the rapid spread of tick-borne diseases. Development of strategies for protection of the health of companion animals in different geographic regions should take into account the potential emergence of unknown animal tick-borne diseases that can be transmitted by imported ticks.
