Diagnosis of Hepatozoon spp. in Amblyomma ovale and its experimental transmission in domestic dogs in Brazil

Veterinary Parasitology, 2005
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.

Altitudinal Assessment ofAmblyomma aureolatumandAmblyomma ovale(Acari: Ixodidae), Vectors of Spotted Fever Group Rickettsiosis in the State of São Paulo, Brazil

Journal of Medical Entomology, 2015
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

Description of the larva of Amblyomma ovale Koch, 1844 (Acari: Ixodidae) by light and scanning electron microscopy

Systematic and Applied Acarology, 2008
The larval stage of Amblyomma ovale Koch is described using optical and scanning electron microscopy. Unfed larvae were obtained from a colony of A. ovale originating from engorged females collected on domestic dogs from Monte Negro County, state of Rondonia, Western Amazon, Brazil. Fifteen larvae were prepared and mounted on slides, and observed under

Impact of climate change on the geographical distribution of ticks of public health significance in Colombia: Amblyomma ovale (Ixodida: Ixodidae), the Amblyomma maculatum (Ixodida: Ixodidae) complex and the Amblyomma cajennense (Ixodida: Ixodidae) complex

Journal of Medical Entomology
Abstract Ticks of the Amblyomma maculatum (Ixodida Ixodidae) complex, the Amblyomma cajennense (Ixodida Ixodidae) complex and Amblyomma ovale (Ixodida Ixodidae) are known to transmit various Rickettsia species in Colombia, but their exact distribution is unknown.
