Amblyomma ovale parasitizing a human
Comparative Clinical Pathology, 2017The present study aims to report a case study regarding the parasitism in humans due to Amblyomma ovale in the west side of Santa Catarina, southern Brazil. The parasitized individual noticed the ectoparasite after visiting an area of forest and riverbank in that region, site also visited by cattle. The tick was then removed and placed in a 70% alcohol

Current status of Amblyomma ovale (Acari: Ixodidae) in Panama
Ticks and Tick-borne Diseases, 2013 The genus Amblyomma is the most diverse and relevant among the Neotropical ticks. In Panama, this genus contains 19 species, including Amblyomma ovale. There is a lack of knowledge of the ecology of A. ovale in Panama, and thus the aim of this work is to report on its geographical distribution and its spectrum of vertebrate hosts.

Comparative analysis of germ cells and DNA of the genus Amblyomma: adding new data on Amblyomma maculatum and Amblyomma ovale species (Acari: Ixodidae) [PDF]
Parasitology Research, 2017 Among tick species, members of the subfamily Amblyomminae have received special attention, since they serve as vectors for pathogens such as Rickettsia spp. and display cryptic species complexes that make their taxonomical classification challenging.

First occurrence of Amblyomma ovale in the State of Rio Grande do Norte, Brazil [PDF]
Brazilian Journal of Veterinary Parasitology, 2013 This study aims to report the occurrence of parasitism byAmblyomma ovale (Koch, 1844) in dogs in the municipality of Apodi, Rio Grande do Norte, Brazil. Specimens were identified as being one female and two males of A. ovale, besides; the animal was infested by five females of Rhipicephalus(Boophilus) microplus and seven females and three males of R ...

Life-cycle and host preference of Amblyomma ovale (Acari: Ixodidae) under laboratory conditions
Experimental and Applied Acarology, 2011This study evaluated for the first time the life cycle of Amblyomma ovale in the laboratory. For this purpose, larvae and nymphs were exposed to Gallus gallus (chickens), Cavia porcellus (guinea pigs), Rattus norvegicus (wistar rats), Oryctolagus cuniculus (domestic rabbits), Calomys callosus (vesper mouse), and Didelphis albiventris (white-eared ...

A high gene flow in populations of Amblyomma ovale ticks found in distinct fragments of Brazilian Atlantic rainforest [PDF]
Experimental and Applied Acarology, 2019 The genetic structure of populations of the tick Amblyomma ovale from five distinct areas of the Brazilian Atlantic rainforest was evaluated via DNA sequencing and associated with the presence of domestic dogs acting as hosts at the edge of forest fragments. Ticks were collected from domestic dogs and from the environment between 2015 and 2017.

DNA sequences of Amblyomma aureolatum (Pallas, 1772) and Amblyomma ovale Koch, 1844 were obtained to determine genetic differences between these tick species. Collections of these species are discussed in relation to distribution and hosts. Seven ticks collections (four from Brazil, one from Argentina, one from Uruguay and one from USA) house a total ...

Transmission of Hepatozoon spp. to dogs was investigated using four species of ixodid ticks: Rhipicephalus sanguineus, Amblyomma aureolatum, Amblyomma ovale and Amblyomma cajennense. We collected completely or partially engorged adult ticks of these species from dogs that were naturally infested and positive for Hepatozoon spp.

Amblyomma aureolatum (Pallas) and Amblyomma ovale Koch are common ectoparasites of domestic dogs in São Paulo state, southeastern Brazil, where they are vectors of distinct spotted fever group rickettsioses, one caused by Rickettsia rickettsii (transmitted by A. aureolatum), and the other caused by Rickettsia sp. strain Atlantic rainforest (transmitted
