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.

Amblyomma cajennense (Fabricius, 1787) (Acari: Ixodidae), the Cayenne tick: phylogeography and evidence for allopatric speciation [PDF]
BMC Evol Biol, 2013 Amblyomma cajennense F. is one of the best known and studied ticks in the New World because of its very wide distribution, its economical importance as pest of domestic ungulates, and its association with a variety of animal and human pathogens.

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 ...

Inhibition of the classical pathway of the complement system by saliva of Amblyomma cajennense (Acari: Ixodidae) [PDF]
Exp Parasitol, 2016 Inhibition of the complement system during and after haematophagy is of utmost importance for tick success in feeding and tick development. The role of such inhibition is to minimise damage to the intestinal epithelium as well as avoiding inflammation ...

Amblyomma cajennense is an intrastadial biological vector of Theileria equi. [PDF]
Parasit Vectors, 2013 BACKGROUND: The apicomplexan hemoprotozoan parasite Theileria equi is one of the etiologic agents causing equine piroplasmosis, a disease of equines that is endemic throughout large parts of the world. Before 2009 the United States had been considered to

Diversity of Ticks in the Caribbean Region and Detection of Their Pathogens Using BioMark Technology [PDF]
Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.Introduction Ticks and the pathogens they transmit are widespread in Caribbean animal populations. There is; however, limited information on the diversity of ticks and tick‐borne pathogens (TTBPs) in the region. This study aims to identify TTBPs across multiple Caribbean countries using a high‐throughput real‐time microfluidic PCR system.

Automated identification of spotted‐fever tick vectors using convolutional neural networks [PDF]
Medical and Veterinary Entomology, Volume 39, Issue 4, Page 829-841, December 2025.We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.

Immunosuppressive effects of Amblyomma cajennense tick saliva on murine bone marrow-derived dendritic cells [PDF]
Parasit Vectors, 2015 BackgroundDendritic cells (DCs) are professional antigen-presenting cells with vital roles in the activation of host immunity. Ticks are bloodsucking arthropods that secrete bioactive compounds with immunomodulatory properties via their saliva.

Wild birds as hosts of Amblyomma cajennense (Fabricius, 1787) (Acari: Ixodidae) [PDF]
Memorias do Instituto Oswaldo Cruz, 1999 We evaluated the prevalence, mean intensity and relative density of ticks in 467 wild birds of 67 species (12 families) from forest and cerrado habitats at two protected areas of Minas Gerais, between March and September 1997.
