Characterization of the bacterial microbiome of Amblyomma scalpturatum and Amblyomma ovale collected from Tapirus terrestris “Tapir” and Amblyomma sabanerae collected from Chelonoidis denticulate “Motelo”, Madre de Dios- Peru

, 2022
Abstract Ticks are reservoirs and vectors of pathogens of importance in animal and human health. These microorganisms in ticks can play different roles such as endosymbiont, pathogenic, and even unknown. Here we report the bacterial microbiome of adult males Amblyomma scalpturatum and Amblyomma ovale ticks (GARS) collected from Tapirus ...

Challenging the Clinical Paradigm of Hepatozoon canis: A Primary Pathogen Causing Clinically Significant Disease at Low Parasitaemia and a Chronic Inflammatory State

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Hepatozoon canis causes significant clinical disease even at low parasitaemia and induces chronic subclinical anaemia and inflammation in dogs. Lack of tick control is the main modifiable risk factor. Molecular diagnosis is far more sensitive than microscopy, challenging the traditional view that disease severity depends solely on parasite burden ...

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, Volume 40, Issue 1, Page 91-100, March 2026.
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.

Parasitism by Amblyomma ovale on domestic dog in the central region of the state of Rio Grande do Sul, Brazil

Acta Scientiarum. Animal Sciences, 2023
Ticks are obligate ectoparasite arthropods of the class Arachnida distributed worldwide and can parasitize many animals. They constitute one of the most important groups of vectors of infectious diseases, including zoonoses. The objective of this study was to report the parasitism by Amblyomma ovale Koch, 1844 in a domestic dog (Canis lupus familiaris ...

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

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.

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...
