“…Three distinct rickettsial strains (COOPERI, NOD, and ApPR) have been reported from different Amblyomma ticks in Brazil (162,(198)(199)(200). Indeed, these strains are regarded as potential pathogens because they are phylogenetically related to the pathogens R. parkeri, R. africae, R. sibirica, and the Atlantic rainforest strain (200).…”

SUMMARY Tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus Rickettsia . These zoonoses are among the oldest known vector-borne diseases. However, in the past 25 years, the scope and importance of the recognized tick-associated rickettsial pathogens have increased dramatically, making this complex of diseases an ideal paradigm for the understanding of emerging and reemerging infections. Several species of tick-borne rickettsiae that were considered nonpathogenic for decades are now associated with human infections, and novel Rickettsia species of undetermined pathogenicity continue to be detected in or isolated from ticks around the world. This remarkable expansion of information has been driven largely by the use of molecular techniques that have facilitated the identification of novel and previously recognized rickettsiae in ticks. New approaches, such as swabbing of eschars to obtain material to be tested by PCR, have emerged in recent years and have played a role in describing emerging tick-borne rickettsioses. Here, we present the current knowledge on tick-borne rickettsiae and rickettsioses using a geographic approach toward the epidemiology of these diseases.

“…It is important to note that spotted fever group Rickettsia have been found in A. nodosum ticks parasitizing birds (OGRZEWALSKA et al, 2009b), but a link with human diseases has not yet been established. In a recent report by Almeida et al (2013), this agent was found in A. nodosum ticks collected from anteaters in Mato Grosso do Sul.…”

Herein, we report tick species found on wild and domestic animals and in the environment during a one-year sampling period at the Brazilian Farming Research Company beef cattle unit (Embrapa Beef Cattle), which is located within the urban area of Campo Grande, Mato Grosso do Sul, Brazil. From 55 wild hosts including six different species (Nasua nasua, Cebus spp., Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla and Dasyprocta aguti), 323 ticks were collected. Amblyomma ovale ticks were found solely on coatis, and Amblyomma nodosum was identified solely on anteaters. No ticks were found on capuchin monkeys. However, Amblyomma cajennense was found on all parasitized host species with the exception of capuchin monkeys. Giant anteaters displayed the highest infestation abundance, with a mean of 53 ticks/animal. Environmental sampling yielded 166 adult A. cajennense ticks. The tick species found on domestic animals (Rhipicephalus (Boophilus) microplus, R. sanguineus, Dermacentor nitens and A. cajennense) were those typically found on these hosts in Brazil. The most prevalent tick species, A. cajennense, was found on both wild and domestic animals and was also prevalent in the environment. Thus, this tick species is the primary vector that allows pathogens to bridge wild and domestic animals in the Cerrado.Keywords: Ticks, wild animals, urban area, Campo Grande, Mato Grosso do Sul. ResumoNeste trabalho são descritas as espécies de carrapatos de animais selvagens e domésticos e do ambiente coletados por um ano na EMBRAPA Gado de Corte localizado na área urbana de Campo Grande, Mato Grosso do Sul, Brasil. Dos 55 hospedeiros selvagens de seis espécies diferentes (Nasua nasua, Cebus spp., Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla e Dasyprocta aguti) foram coletados 323 carrapatos. Amblyomma ovale foi encontrado apenas em quatis e Amblyomma nodosum apenas sobre tamanduás. Nenhum carrapato foi encontrado sobre macacos-prego. Por outro lado, Amblyomma cajennense foi encontrado em todos os hospedeiros com exceção dos macacos-pregos. A maior abundancia de infestação foi aquela em tamanduás-bandeira com média de 53 carrapatos/animal. No ambiente foram capturados 166 carrapatos, todos da espécie A. cajennense. As espécies de carrapatos em animais domésticos (Rhipicephalus (Boophilus) microplus, Rhipicephalus sanguineus, Dermacentor nitens e A. cajennense) foram aquelas características nestes hospedeiros no Brasil. De forma geral a espécie de carrapato A. cajennense foi a mais prevalente sendo encontrada em animais domésticos e selvagens bem como no ambiente. Portanto, esta é a principal espécie de vetor a estabelecer uma ponte para bioagentes patogênicos entre animais domésticos e selvagens.Palavras-chave: Carrapato, animais selvagens, área urbana, Campo Grande, Mato Grosso do Sul.
