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.

Strategies for the control of Rhipicephalus microplus ticks in a world of conventional acaricide and macrocyclic lactone resistance

Parasitology Research, 2017
Infestations with the cattle tick, Rhipicephalus microplus, constitute the most important ectoparasite problem for cattle production in tropical and subtropical regions worldwide, resulting in major economic losses. The control of R.

Status of Rhipicephalus microplus resistance to ivermectin, fipronil and fluazuron in Mato Grosso do Sul, Brazil.

Revista brasileira de parasitologia veterinaria = Brazilian journal of veterinary parasitology : Orgao Oficial do Colegio Brasileiro de Parasitologia Veterinaria, 2021
Southern cattle tick resistance to pour-on and injectable acaricides has yet to be evaluated on a broader scope, and the paucity of information on the subject may hinder efforts to control this parasite.

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.

Homology modeling, docking, molecular dynamics and in vitro studies to identify Rhipicephalus microplus acetylcholinesterase inhibitors

Journal of Biomolecular Structure and Dynamics, 2021
Rhipicephalus microplus is an important ectoparasite of cattle, causing considerable economical losses. Resistance to chemical acaricides has stimulated the search for new antiparasitic drugs, including natural products as an eco-friendly alternative of ...

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 ...

Rickettsia spp. and Anaplasmataceae in Ticks From Domestic Animals in Northern Colombia

Zoonoses and Public Health, Volume 72, Issue 5, Page 421-434, August 2025.
ABSTRACT Introduction Tick‐borne diseases have a significant impact on public and animal health and represent a considerable financial burden on livestock farming. However, in many regions of Latin America, comprehensive epidemiological data, including species identification, geographical distribution and molecular profiling of ticks and their ...
