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.

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.

Virome analyses of Amblyomma cajennense and Rhipicephalus microplus ticks collected in Colombia. [PDF]

Acta Trop
Tick-borne viruses (TBV) have gained public health relevance in recent years due to the recognition of human-associated fatal cases and the increase in tick-borne disease and transmission. However, many tick species have not been studied for their potential to transmit pathogenic viruses, especially those found in Latin America.

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.
