Bacteria associated with Amblyomma cajennense tick eggs. [PDF]

Genet Mol Biol, 2015
Ticks represent a large group of pathogen vectors that blood feed on a diversity of hosts. In the Americas, the Ixodidae ticks Amblyomma cajennense are responsible for severe impact on livestock and public health. In the present work, we present the isolation and molecular identification of a group of culturable bacteria associated with A.

Antiviral effect of the egg wax of Amblyomma cajennense (Acari: Ixodidae). [PDF]

Cytotechnology, 2012
The control of viral infections, especially those caused by influenza viruses, is of great interest in Public Health. Bio prospection has shown the presence of active principles in the hemolymph of arthropods, and in the salivary gland of ticks, and some of these are of interest for the development of new pharmacological drugs.

Seasonal dynamics of the Cayenne tick, Amblyomma cajennense on horses in Brazil [PDF]

Medical and Veterinary Entomology, 2003
Abstract.  The population dynamics of all stages of the Cayenne tick, Amblyomma cajennense (Fabricius) (Acari: Ixodidae) on horses was evaluated over a period of 2 years in the district of Pedro Leopoldo, State of Minas Gerais, Brazil. Every 14 days, the left side of 20 horses was brushed for collection of immature stages; counts of adults were also ...

Lack of parthenogenesis by Amblyomma cajennense (Acari: Ixodidae) [PDF]

Memórias do Instituto Oswaldo Cruz, 2002
Some reproductive parameters of adult stages of Amblyomma cajennense ticks were studied. The capacity of virgin females to reproduce by parthenogenesis was evaluated, during an experimental infestation, in absence of males, on a horse (Equus cabalus). Ticks were spread either completely free or in limited sites on the body of the animal.

Efficacy of sarolaner (Simparic™) against induced infestations of Amblyomma cajennense on dogs. [PDF]

Parasit Vectors, 2017
Amblyomma cajennense is the main vector of Rickettsia rickettsii which causes Brazilian spotted fever. This adult tick preferably infests horses and capybaras, but has low host specificity during its immature stages, thus posing a threat to humans and dogs.

First report of Amblyomma sculptum (Amblyomma cajennense complex) in a Brazilian state classified as a silent area for human rickettsiosis. [PDF]

Vet World, 2023
Background and Aim: Studies on ticks of public health concern in equine husbandry are scarce in the Northeastern region of Brazil. This study aimed to investigate the presence of ticks on horses in the State of Alagoas, which is classified as a silent area for human rickettsiosis.

Divergent environmental preferences and areas of sympatry of tick species in the Amblyomma cajennense complex (Ixodidae) [PDF]

International Journal for Parasitology, 2014
Four species of Neotropical ticks, Amblyomma mixtum, Amblyomma cajennense, Amblyomma tonelliae and Amblyomma sculptum (formerly included in the catch-all name A. cajennense), have an allopatric distribution in much of their range, with areas of parapatry
