Resistance of the cattle tick Rhipicephalus (Boophilus) microplus to fluazuron in Argentina

Experimental and Applied Acarology, 2022
The aim of this work is to report the presence of resistance to fluazuron in a population of Rhipicephalus microplus in Argentina. The evidence was obtained from field and in vitro trials. In the field trial, cattle infested with ticks was treated with two commercial formulations of fluazuron.

Resistance of the cattle tick Rhipicephalus (Boophilus) microplus to ivermectin in Argentina

Research in Veterinary Science, 2020
Resistance to ivermectin in populations of the cattle tick Rhipicephalus microplus in Argentina was diagnosed in this work. The in vitro larval immersion test (LIT) was used to determine quantitatively the levels of resistance to ivermectin in different populations of R. microplus.

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 ...

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.

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.

ABC transporters as a multidrug detoxification mechanism in Rhipicephalus (Boophilus) microplus

Parasitology Research, 2012
ATP-binding cassette (ABC) transporters are responsible for pumping drugs across membranes and are an important drug detoxification mechanism. Since ABC transporters act on a wide spectrum of chemical compounds, they have been associated with multidrug resistance phenotype in various parasites and cancer cells.

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.

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.

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).

Population structure of Australian isolates of the cattle tick Rhipicephalus (Boophilus) microplus

Veterinary Parasitology, 2009
Since its introduction in Australia, and despite decades of movement control, the cattle tick, Rhipicephalus (Boophilus) microplus, has spread widely in suitable habitat in the Northern Territory and the state of Queensland (QLD). On the east coast, its southerly distribution is limited by a tick quarantine line on the border with the state of New ...
