Spotted fever group Rickettsia and Borrelia sp. cooccurrence in Amblyomma sculptum in the Midwest region of Brazil

Experimental & applied acarology, 2020
More than 70 tick species are found in Brazil, distributed over five genera and including main vectors of infectious disease agents affecting both animals and humans. The genus Amblyomma is the most relevant for public health in Brazil, wherein Amblyomma

Amblyomma humerale

, 2012
Amblyomma humerale Amblyomma humerale was collected from yellowfooted tortoise, Geochelone denticulate from Mayaro (Aitken et al. 1968a; Robbins et al. 2003). Everard and Tikasingh (1973) found A. humerale on rodents (Oryzomys capito and Proechimys guyannensis) from Turure Forest, Trinidad. Nava et al.

Automated identification of spotted‐fever tick vectors using convolutional neural networks

Medical and Veterinary Entomology, EarlyView.
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.

Ticks and tick‐borne bacterial pathogens found on hard ticks (Acari: Ixodidae) on cattle in the Central River region of The Gambia

Medical and Veterinary Entomology, EarlyView.
First detection of Ehrlichia minasensis, Anaplasma marginale and hemotropic Mycoplasma spp. in cattle in The Gambia. Identification of four tick species, with Hyalomma marginatum being the most common. 15.6% of ticks tested positive for tick‐borne pathogens, including Ehrlichia spp., A. marginale and hemotropic Mycoplasma spp.
