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.

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.

Baseline susceptibility of Haemaphysalis longicornis to organophosphate, carbamate, and pyrethroid acaricides

Pest Management Science, Volume 79, Issue 11, Page 4328-4334, November 2023., 2023
The baseline susceptibility of Haemaphysalis longicornis to organophosphate, carbamate and pyrethroid acaricides was calculated using a larval package approach. Results indicate that the Asian longhorned tick is susceptible to pyrethroids, coumaphos and carbamates, and should also be effective for controlling H. longicornis.

A risk assessment of equine piroplasmosis entry, exposure and consequences in the UK

Equine Veterinary Journal, Volume 55, Issue 2, Page 282-294, March 2023., 2023
Abstract Background Equine piroplasmosis (EP) is currently not endemic in the UK, despite a lack of formal surveillance and the presence of carrier horses in the equine population. Pathogen establishment would have significant welfare and economic impacts on the national equine industry, but the disease is often overlooked by UK practitioners ...

Controle estratégico do carrapato Amblyomma cajennense em eqüinos [PDF]

Ciência Rural, 2004
Avaliou-se quantitativamente as infestações por adultos de Amblyomma cajennense em eqüinos mantidos sob infestações naturais em uma pastagem (pastagem 1), antes e após o uso de tratamentos carrapaticidas. Os tratamentos foram aplicados nos eqüinos a cada sete dias durante os períodos de predomínio das larvas e ninfas do carrapato, no Estado de São ...
