Acaricide activity in vitro of Acmella oleracea against Rhipicephalus microplus [PDF]

Parasitology Research, 2014
Cattle tick control has been limited by the resistance of these parasites to synthetic acaricides. Natural products are a possible alternative as they have different mechanisms of action. Acmella oleracea is a native plant with a large cultivated area in the Amazon region and could be easily used for large-scale preparation of a commercial product ...

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

Ticks on pastures and on two breeds of cattle in the Eastern Cape province, South Africa

Onderstepoort Journal of Veterinary Research, 2011
Many studies on the population dynamics of questing ticks on pastures and of parasitic ticks on cattle have been conducted. Few, however, have attempted to link the two in a single study.

Carryover Effects of Thermal Conditions on Tick Survival, Behavior, and Simulated Detectability

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Recent thermal history affects the abundance and behavior of adult Amblyomma americanum. Thermal responses impacted simulated tick detection through combined effects on movement and mortality. ABSTRACT Carryover effects occur when environmental history of an organism influences its behavior, fitness, and population dynamics.

Triosephosphate isomerase from Fasciola hepatica: high‐resolution crystal structure as a drug target

Acta Crystallographica Section F, Volume 81, Issue 9, Page 381-387, September 2025.
The high‐resolution crystal structure of triosephosphate isomerase from F. hepatica was solved at 1.51 Å resolution in its monoclinic form, revealing details of the dimer interface critical for enzyme function. Molecular docking with the fasciolocide triclabendazole suggests selective binding near nonconserved residues, highlighting this enzyme as a ...
