Helminths, Ticks, and Calf Mortality in Ethiopia: A Prospective Cohort Study

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
There is a significant demand for animal products in Ethiopia, driven by the country’s rapid urbanization and population growth. In contrast, calf death has been hindering cattle productivity. This study investigated helminth and tick species affecting calves and evaluated whether calf mortality exceeded accepted management thresholds.

Risk for Human Tick-Borne Encephalitis, Borrelioses, and Double Infection in the Pre-Ural Region of Russia

Emerging Infectious Diseases, 2001
We assessed the risk for human tick-borne encephalitis (TBE), ixodid tick-borne borrelioses, and double infection from 1994 to 1998 in Perm, which has among the highest rates of reported cases in Russia.

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.

Acquired resistance to ixodid ticks induced by tick cement antigen

Experimental & Applied Acarology, 1989
Antisera from guinea pigs made resistant to infestation with an ixodid tick of east and central Africa, Rhipicephalus appendiculatus, were used to identify the tick antigens they recognized by immunoblotting. Most of the antigens were found in tick salivary glands and in tick attachment cement. Antisera from R. appendiculatus-resistant guinea pigs also

Stable isotope analysis of ectoparasites as a tool for understanding trophic interactions with mammalian hosts

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 664-674, December 2025.
Ectoparasites showed significant δ15N enrichment compared to their hosts, indicating trophic enrichment, but δ13C preservation varied. Lice, fleas and ticks preserve their hosts' isotopic fingerprints to varying degrees, with lice reflecting host dietary patterns most closely, likely due to their exclusive, host‐specific feeding behaviour. The presence

Harnessing 50 years of tick population genetics: Choosing the right molecular tool for contemporary research

Journal of Animal Ecology, Volume 94, Issue 11, Page 2159-2177, November 2025.
Population genetics reveals how ticks interact with hosts, microbiomes and environments. This review guides researchers in choosing the best tool for the job, weighing cost, resolution, reproducibility and throughput to study tick population structure. Abstract Ticks are ectoparasites of major medical, veterinary and ecological importance, transmitting
