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 ...

An update on distribution models for Rhipicephalus microplus in West Africa

Geospatial health, 2013
The cattle tick, Rhipicephalus microplus, which reached the West African region approximately 8 years ago, has established viable populations in Côte d'Ivoire and Benin and spread rapidly from the assumed points of introduction. However, existing maps of its distribution range do not agree on the areas at risk, most probably due to suboptimal modelling

Modelling the distribution of Rhipicephalus microplus and R. decoloratus in Zimbabwe

Veterinary Parasitology: Regional Studies and Reports, 2018
Species distribution modelling is a very useful tool in vector management. Ticks are vectors of various pathogens which cause serious problems in livestock production in tropical countries. They have a high dispersal potential which is mainly facilitated by the movement of animals from one area to another.

Viral diversity of Rhipicephalus microplus parasitizing cattle in southern Brazil [PDF]

Scientific Reports, 2018
AbstractTicks are ectoparasites spread worldwide and are well known as vectors of many viruses of great importance to human and animal health. However, the viral diversity in ticks is still poorly understood, particularly in South America. Here we characterized the viral diversity present in Rhipicephalus microplus parasitizing cattle in the southern ...

The potential of Rhipicephalus microplus as a vector of Ehrlichia ruminantium in West Africa

Ticks and Tick-borne Diseases, 2023
Heartwater, or cowdriosis, is a virulent tick-borne rickettsial disease of ruminants caused by Ehrlichia ruminantium, biologically transmitted by Amblyomma species (A. variegatum in West Africa). In West Africa, this bacterium was recently reported to naturally infect the invasive cattle tick, Rhipicephalus microplus (Rm) through trans-ovarian ...

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.

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 ...

Evaluation of phytotherapy alternatives for controlling Rhipicephalus (Boophilus) microplus in vitro [PDF]

Revista Brasileira de Parasitologia Veterinária, 2017
Abstract The objective of this study was to identify the main chemical components of the essential oil of Cuminum cyminum L. (cumin) and of the fixed oils of Bertholletia excelsa (Brazil nut) and of Helianthus annuus (sunflower seed). As well as testing the three oils and three different commercial synthetic acaricides against engorged females of ...

Lactate Dehydrogenase/Albumin to Urea Ratio: A Novel Prognostic Indicator for Adverse Outcomes in Patients With Severe Fever With Thrombocytopenia Syndrome

Journal of Medical Virology, Volume 97, Issue 6, June 2025.
ABSTRACT Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease with significant mortality risks. This study evaluated the predictive value of the lactate dehydrogenase/albumin to urea ratio (LAU) for lethal outcomes in SFTS patients.

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 ...
