Genetic susceptibility to Theileria orientalis (Ikeda) in Angus‐ and Hereford‐sired yearling cattle born to dairy cattle on an endemically infected farm in New Zealand

New Zealand Journal of Agricultural Research, Volume 67, Issue 5, Page 565-573, October 2024.
ABSTRACT Theileria orientalis (Ikeda) was first detected in New Zealand in 2012, becoming endemic in most of the North Island, and can cause incidences of anaemia and death. Research has been performed in New Zealand on the incidence and severity of infection.

Effects of urea on the cattle tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)

Veterinary Parasitology, 2010
This study aimed at evaluating the effects of urea on Rhipicephalus (Boophilus) microplus. The experiment was divided into two stages. In Stage I, Brachiaria brizantha was placed into 30 pots, each with an area of 18 cm(2).These were divided into three groups of ten pots each: G1 non-treated control group, G2 treated with 15 g of urea per pot and G3 ...

Insights from entire mitochondrial genome sequences into the phylogeny of ticks of the genera Haemaphysalis and Archaeocroton with the elevation of the subgenus Alloceraea Schulze, 1919 back to the status of a genus

Medical and Veterinary Entomology, Volume 38, Issue 2, Page 189-204, June 2024.
We sequenced the entire mt genomes of three species of tick for the first time: Bothriocroton auruginans, B. hydrosauri and H. (Kaiseriana) novaeguineae, and we sequenced the 18S rRNA gene of B. hydrosauri and H. (Kaiseriana) bancrofti. In our phylogenetic trees, Alloceraea was the sister to Archaeocroton sphenodonti, from New Zealand; to the exclusion

Bovine immunoprotection against Rhipicephalus (Boophilus) microplus with recombinant Bm86-Campo Grande antigen Imunoproteção de bovinos contra Rhipicephalus (Boophilus) microplus com antígeno recombinante Bm86-Campo Grande

Revista Brasileira de Parasitologia Veterinária, 2012
The southern cattle fever tick, Rhipicephalus (Boophilus) microplus, is no doubt the most economically important ectoparasite of cattle globally. The inappropriate use of chemical acaricides has driven the evolution of resistance in populations of R. (B.)

Vitellin- and hemoglobin-digesting enzymes in Rhipicephalus (Boophilus) microplus larvae and females

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2010
The aim of the present study was to address the involvement of Rhipicephalus microplus larval cysteine endopeptidase (RmLCE) in protein digestion in R. microplus larvae and adult females. In this work, an improved purification protocol for native RmLCE was developed.

Characterisation of putative novel tick viruses and zoonotic risk prediction

Ecology and Evolution, Volume 14, Issue 1, January 2024.
Tick‐borne viruses remain a substantial zoonotic risk worldwide, so knowledge of the diversity of tick viruses has potential health consequences. Through data mining and bioinformatic analyses of more than 37,800 public meta‐genomic and ‐transcriptomic data sets, we found five putative novel Alphatetra‐like viruses, four putative novel Orthomyxo‐like ...

Molecular Identification of Hyalomma Ticks and Application of Bacillus thuringiensis Toxins as an Effective Biological Acaricide

Journal of Parasitology Research, Volume 2024, Issue 1, 2024.
Bacillus thuringiensis (B. thuringiensis) is considered one of the most important entomopathogenic microorganisms. It produces potent toxins against insects. Therefore, the present study investigates the bioacaricidal properties of B. thuringiensis on the Hyalomma tick species.

Immunogenic potential of Rhipicephalus (Boophilus) microplus aquaporin 1 against Rhipicephalus sanguineus in domestic dogs [PDF]

Revista Brasileira de Parasitologia Veterinária, 2017
Abstract This study evaluated a recombinant aquaporin 1 protein of Rhipicephalus (Boophilus) microplus (RmAQP1) as antigen in a vaccine against R. sanguineus. Five dogs were immunized with RmAQP1 (10 µg) + adjuvant (Montanide) (G1), and five were inoculated with adjuvant only (G2), three times.

Rhipicephalus (Boophilus) microplus aquaporin as an effective vaccine antigen to protect against cattle tick infestations

Parasites & Vectors, 2014
Background Vaccination as a control method against the cattle tick, Rhipicephalus (Boophilus) microplus has been practiced since the introduction of two products in the mid-1990s.
