“…The tick species A. rotundatum is widely distributed across all regions of Brazil ( Polo et al, 2021 ), with a higher frequency of reports in the North and Northeast regions. It has been observed parasitizing various species of reptiles and amphibians in these areas ( Alcantara et al, 2018 ; Dantas-Torres et al, 2010a ; Dantas-Torres et al, 2010b ; Martins et al, 2020 ; Oda et al, 2018 ).…”

“…Despite its narrow specificity for reptiles and amphibians and its wide geographic distribution, studies have indicated a sympatric relationship between A. rotundatum and A. dissimile , a tick species closely associated with reptiles and amphibians. This highlights the need for a more detailed description of the hosts of each species to facilitate the development of robust epidemiological and parasitic studies ( Polo et al, 2021 ; Scott & Durden, 2015 ).…”

Amblyomma rotundatum is a tick species commonly found on reptiles and amphibians. In Brazil, investigations of this ectoparasite have indicated its distribution across all Brazilian biomes, although it is concentrated in certain locations. In this context, the objective of the present study was to describe a case of parasitism by A. rotundatum in a red-footed tortoise ( Chelonoidis carbonarius ) in the state of Rio de Janeiro. A female red-footed tortoise ( C. carbonarius ), seized by the environmental police, was parasitized by a tick in the left periocular region. The tick was manually removed, preserved in 70º GL ethanol, and sent for identification at the Federal Rural University of Rio de Janeiro (UFRRJ). Based on the morphological evaluation Dantas-Torres et al. (2019), Barros-Battesti et al. (2006) and Lampo et al. (1997), a diagnosis of a female specimen of A. rotundatum was made. In conclusion, this study reports the first case of A. rotundatum parasitizing C. carbonarius in the state of Rio de Janeiro, highlighting the presence of periocular blepharitis associated with this parasitism.

“…According to the literature, A. rotundatum seems to be a species that is widely distributed in Brazil. Its presence has been reported in all regions of the country, encompassing the states of Acre, Amazonas, Rondônia, Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Pará, Paraná, Maranhão, Pernambuco, Ceará, Rio Grande do Sul, Rio de Janeiro, Santa Catarina and São Paulo (Labruna et al, 2005a;Polo et al, 2021).…”

The aim of the present study was to report on the occurrence of parasitism by Amblyomma rotundatum ticks on two species of Teiidae lizards and test the presence of rickettsiae in the collected ticks, in the western Brazilian Amazon region. Ticks were collected in July 2019, from a fragment of terra firme forest in the municipality of Senador Guiomard, Acre, Brazil. Two lizards that were infested by immature stages of ticks were caught using mist net and Tomahawk traps. Ectoparasites were collected manually, and the lizard specimens were identified and released at the same location where they had been caught. Three nymphs and 49 larvae were collected from Ameiva ameiva, while 25 nymphs and nine larvae were collected from Tupinambis cuzcoensis, which are both in the family Teiidae. The ticks were identified morphologically as belonging to the genus Amblyomma. Nymphs were identified at species level through molecular analysis, resulting in the tick species Amblyomma rotundatum. This is the first record of parasitism by the tick A. rotundatum on T. cuzcoensis lizard, and the first report of an association between A. rotundatum and the lizard species A. ameiva and T. cuzcoensis in Acre, in the western part of the Amazon region.

“…This is also the case of the evolution of VBDs, where many pathogens have a clade or cluster of species associated to reptiles or ectothermic tetrapods, like the reptile-associated Borrelia group ( Morales-Diaz et al, 2020 ), or the reptile clade of Leishmania (subgenus Sauroleishmania ) ( Tuon et al, 2008 ). Also, some parasitic arthropods became well adapted to their reptilian host producing minimum deleterious effects on them ( Bertrand et al, 2002 ; Bower et al, 2019 ), such as in the case of Amblyomma rotundatum ticks infesting reptiles in South America ( Polo et al, 2021 ; Mendoza-Roldan et al, 2020a ), or Ixodes ricinus parasitizing wild lizards ( Lacerta agilis ) in Europe ( Wieczorek et al, 2020 ). Conversely, other parasitic arthropods (e.g., Ophionyssus natricis mites in snakes) may have a pronounced deleterious effect on their hosts, when there is a high parasitic load ( Fuantos-Gámez et al, 2020 ).…”

Reptile vector-borne diseases of zoonotic concern

Reptile vector-borne diseases (RVBDs) of zoonotic concern are caused by bacteria, protozoa and viruses transmitted by arthropod vectors, which belong to the subclass Acarina (mites and ticks) and the order Diptera (mosquitoes, sand flies and tsetse flies). The phyletic age of reptiles since their origin in the late Carboniferous, has favored vectors and pathogens to co-evolve through millions of years, bridging to the present host-vector-pathogen interactions. The origin of vector-borne diseases is dated to the early cretaceous with Trypanosomatidae species in extinct sand flies, ancestral of modern protozoan hemoparasites of zoonotic concern (e.g., Leishmania and Trypanosoma ) associated to reptiles. Bacterial RVBDs are represented by microorganisms also affecting mammals of the genera Aeromonas, Anaplasma, Borrelia , Coxiella , Ehrlichia and Rickettsia , most of them having reptilian clades. Finally, reptiles may play an important role as reservoirs of arborivuses, given the low host specificity of anthropophilic mosquitoes and sand flies. In this review, vector-borne pathogens of zoonotic concern from reptiles are discussed, as well as the interactions between reptiles, arthropod vectors and the zoonotic pathogens they may transmit.
