Amblyomma cajennense ticks induce immediate hypersensitivity in horses and donkeys

Experimental & Applied Acarology, 2004
Since host immune reaction to ticks interferes with tick-borne pathogen transmission, it is important to recognize naturally occurring tick-host immune relationships to better understand the epidemiology of such infectious diseases. Amblyomma cajennense is an important tick-borne disease vector in the Neotropical region and horses maintain it in ...

Acquired resistance of horses to Amblyomma cajennense (Fabricius, 1787) ticks

Veterinary Parasitology, 2003
Acquired immunity of horses to larvae, nymphs and adults of the Amblyomma cajennense tick was evaluated through three consecutive experimental infestations of tick-bite naïve hosts. Data from these infestations were compared to those from field-sensitized horses and donkeys.

Survival and Water-Balance Characteristics of Unfed Adult Amblyomma cajennense (Acari: Ixodidae)

Journal of Medical Entomology, 1996
Off-host survival, water balance, and cold tolerance of unfed adult, Cayenne ticks, Amblyomma cajennense (F.), were examined to evaluate species characteristics important to zoogeography and off-host ecology. Survivorship decreased when males and females were subjected to progressively drier constant environmental conditions.

Cross-mating experiments with geographically different populations of Amblyomma cajennense (Acari: Ixodidae)

Experimental and Applied Acarology, 2011
The present study evaluated the reproductive compatibility of the crosses between adult ticks of the following three geographically different populations of Amblyomma cajennense: State of São Paulo (SP), southeastern Brazil; State of Rondônia (RO), northern Brazil; and Colombia (CO). In addition, crosses between A.

Salivary glands of Amblyomma cajennense (Acari: Ixodidae): a histological and an ultrastructural overview

Experimental and Applied Acarology, 2011
The present study on the salivary glands of semi-engorged Amblyomma cajennense females has identified the various cell types present in this tissue and allowed its morphohistochemical characterization. Marking techniques were applied to detect polysaccharides (PAS), proteins (bromophenol blue), lipids (Nile blue) and calcium (von Kossa), as well as ...

Natural Infection of the Tick, Amblyomma Cajennense, with Rickettsia Rickettsii in Panama

The American Journal of Tropical Medicine and Hygiene, 1953
The occurrence of Rocky Mountain spotted fever on the Isthmus of Panama was established for the first time in 1950 when a highly virulent strain of Rickettsia rickettsii was isolated by the author from the blood of a 26 year old Panamanian farmer who died February 8 of that year, shortly after admission to the hospital.

Development of Resistance to Nymphs of Amblyomma cajennense Ticks (Acari:Ixodidae) in Dogs

Annals of the New York Academy of Sciences, 2002
Abstract: Ticks have long been regarded as constraints to humans and domestic animals, but hosts often develop resistance to ticks after repeated infestations. The purpose of this investigation was to study the possible acquisition of immunity in domestic dogs to nymphs of A.

Acaricidal activity of thymol on larvae and nymphs of Amblyomma cajennense (Acari: Ixodidae)

Veterinary Parasitology, 2011
The aim of the present study was to evaluate the acaricidal efficacy of thymol on unengorged and engorged larvae and engorged nymphs of Amblyomma cajennense. To perform the test for unengorged larvae, the larval packet technique was employed and mortality was evaluated 24h after the test, while for engorged larvae and engorged nymphs the immersion ...
