Rhipicephalus (Boophilus) microplus embryo proteins as target for tick vaccine

Veterinary Immunology and Immunopathology, 2012
Rhipicephalus (Boophilus) microplus is one of the most widely distributed tick in the world. The control of the parasite is based mainly on the use of chemical acaricides, which are produced from a limited set of molecules. These drugs induce selection of acaricide-resistant ticks, and are an important source of environmental pollution.

Rhipicephalus (Boophilus) microplus

2012
Rhipicephalus (Boophilus) microplus Aitken et al. (1958) recorded a few specimens of the southern cattle tick R. (B.) microplus from cattle and sheep in Trinidad. Williams and Gonzalez (1968) observed that Holstein heifers imported into Trinidad from Canada with the intent to develop a dairy industry were exposed to tick-infested pastures and that ...

Eprinomectin accumulation in Rhipicephalus (Boophilus) microplus: Pharmacokinetic and efficacy assessment

Veterinary Parasitology, 2016
Eprinomectin (EPM) is a macrocyclic lactone used against endo-ectoparasites without withdrawal time in milk and meat after its pour-on administration at 0.5mg/kg. Previous experiments evaluated the efficacy of EPM against Rhipicephalus (Boophilus) microplus in cattle. This study assessed EPM efficacy against R.

Multiple paternity in Rhipicephalus (Boophilus) microplus confirmed by microsatellite analysis

Experimental and Applied Acarology, 2009
The aim of this study was to determine if individual ticks among the progeny of a single female Rhipicephalus (Boophilus) microplus tick removed from cattle under natural conditions are the result of mating with one or several males. To this end, simulations were run using an existing dataset of genotypes from 8 microsatellite loci to predict the ...

Deltamethrin resistance in south Indian isolates of Rhipicephalus (Boophilus) microplus

Veterinary Parasitology: Regional Studies and Reports, 2016
The present communication deals with the detection and characterization of deltamethrin resistance in tick populations using biological (larval packet test), biochemical (esterase enzyme assay) and molecular assays. Ticks were collected from cattle farms of Korutla, Telangana (KOR), Mehboob Nagar, Telangana (MBN), Nagpur, Maharashtra (NAG), Parbani ...

Cross-resistance between fipronil and lindane in Rhipicephalus (Boophilus) microplus

Veterinary Parasitology, 2015
The southern cattle tick, Rhipicephalus (Boophilus) microplus (Canestrini), is one of the most damaging parasites of cattle in tropical and subtropical regions. Several chemical groups have been used for its control, including cyclodienes (lindane and dieldrin).

BYC, an atypical aspartic endopeptidase from Rhipicephalus (Boophilus) microplus eggs

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2008
An aspartic endopeptidase was purified in our laboratory from Rhipicephalus (Boophilus) microplus eggs [Logullo, C., Vaz, I.S., Sorgine, M.H., Paiva-Silva, G.O., Faria, F.S., Zingali, R.B., De Lima, M.F., Abreu, L., Oliveira, E.F., Alves, E.W., Masuda, H., Gonzales, J.C., Masuda, A., and Oliveira, P.L., 1998.

First report of fipronil resistance in Rhipicephalus (Boophilus) microplus of Mexico

Veterinary Parasitology, 2013
Five strains of Rhipicephalus (Boophilus) microplus collected from Tamaulipas Mexico were tested for resistance against several classes of acaricides commonly used. All were resistant to fipronil. Four of five were co-resistant to permethrin and coumaphos in addition to being resistant to fipronil.

A Rhipicephalus (Boophilus) microplus cathepsin with dual peptidase and antimicrobial activity

International Journal for Parasitology, 2012
The cattle tick, Rhipicephalus (Boophilus) microplus, is a haematophagous arthropod responsible for considerable losses in the livestock industry. Immunological control with vaccines is a promising alternative to replace chemical acaricides. Due to their importance in parasite physiology, cysteine endopeptidases are potential targets.

Ixodicide activity of Eysenhardtia polystachya against Rhipicephalus (Boophilus) microplus.

Journal of animal science, 2016
The objective of this study was to evaluate the acaricidal effect of 2 compounds extracted from Eysenhardtia polystachya in vitro, namely coatlines and matlalines. Each extract was obtained by aqueous extraction in a nitrogen atmosphere. Engorged adult females of an amitraz-resistant strain of Rhipicephalus (Boophilus) microplus were used to produce ...
