Ticks (Acari: Ixodidae) and tick-borne agents associated with domestic dogs in an environmental protection area in Brazil, with molecular evidence of Rhipicephalus linnaei (Audouin, 1826) [PDF]

Revista Brasileira de Parasitologia Veterinária
Wild animals and domestic dogs living in human dwellings near forested areas can share ectoparasites, including ticks. In this study, we surveyed ticks associated with dogs which tutors living in the Palmares Environmental Protection Area (EPA Palmares).

Diversity of Ticks in the Caribbean Region and Detection of Their Pathogens Using BioMark Technology. [PDF]

Transbound Emerg Dis
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]

Med Vet Entomol
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.
