Morphological characterization of the ovary and vitellogenesis dynamics in the tick Amblyomma cajennense (Acari: Ixodidae)

Veterinary Parasitology, 2004
In this work we describe the internal morphology of the female reproductive system of the cayenne tick Amblyomma cajennense. This system is represented by a panoistic ovary, which lacks nurse cells in the germarium. This ovary consists of a single tube, in which a large number of oocytes develop asynchronously, thus accompanying the processes of yolk ...

Hypersensitivity Induced in Dogs by Nymphal Extract of Amblyomma cajennense Ticks (Acari:Ixodidae)

Annals of the New York Academy of Sciences, 2002
Abstract: In general, hosts develop resistance to ticks after repeated infestations; nevertheless, several studies on naturally occurring host‐tick interactions were unable to detect resistance of hosts to ticks even after repeated infestations. The purpose of this investigation was to study the type of cutaneous hypersensitivity to unfed nymphal ...

Horse resistance to natural infestations of Anocentor nitens and Amblyomma cajennense (Acari: Ixodidae)

Veterinary Parasitology, 2002
The objective of this study was to investigate some aspects of horse resistance to natural infestations of Anocentor nitens and Amblyomma cajennense over a 2-year period. Free-living stages of A. nitens were used to evaluate the influence of season of the year on horse resistance.

Experimental Transmission of Q Fever by Amblyomma Cajennense

The American Journal of Tropical Medicine and Hygiene, 1949
Since Davis and Cox (1) first isolated the causative agent of Q fever from Dermacentor andersoni, several species of ticks have been incriminated in the epidemiology of this disease in various parts of the world. Investigations implicating the following species were reviewed by Kohls in 1948 (2): in Australia, Haemaphysalis humerosa and H.
