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 ...

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.

Experimental infection of Rickettsia parkeri in the Rhipicephalus microplus tick

Ticks and Tick-borne Diseases, 2018
This study aimed to evaluate, by means of artificial feeding, the interaction between a pathogenic rickettsia and the hard tick R. microplus. We used partially engorged females fed on calves free of Rickettsia spp. Group 1 (G1), containing 20 ticks, was fed bovine blood only.

Rhipicephalus microplus cystatin as a potential cross-protective tick vaccine against Rhipicephalus appendiculatus

Ticks and Tick-borne Diseases, 2020
Rhipicephalus appendiculatus, the brown ear tick, is an important disease vector of livestock in eastern, central and southern Africa. Rhipicephalus appendiculatus acaricide resistance requires the search for alternative methods for its control. Cystatins constitute a superfamily of cysteine peptidase inhibitors vital for tick blood feeding and ...

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 ...

Acaricide resistance status of livestock ticks from East and West Africa and in vivo efficacy of acaricides to control them

International Journal for Parasitology: Drugs and Drug Resistance
Through a collaborative effort across six Sub-Saharan African countries, using recognized international assessment techniques, 23 stocks of three tick species (Rhipicephalus microplus, Rhipicephalus appendiculatus and Amblyomma variegatum) of economic ...
