Abstract

The goal of the present study was to assess the gene expression of xenobiotic metabolizing enzymes (XMEs) Cytochrome P-450 (CYP) and carboxylesterase (CE) related to detoxification of synthetic pyrethroids, plus acetylcholinesterase (AChE), in field isolates of acaricide-resistant Rhipicephalus...

Abstract

Monitoring acaricide resistance and understanding the underlying mechanisms are critically important in developing strategies for resistance management and tick control. Identification of single nucleotide polymorphisms in the acaricide-resistant associated gene of Rhipicephalus microplus has...

Abstract

Acaricide resistance is one of the greatest threats towards the successful control of vector ticks worldwide. Communal farmers of Zimbabwe use amitraz as the most common acaricide with occasional usage of pyrethroids and organophosphates. As a strategy towards developing an effective acaricide...

Abstract

The frequently used chemical control method to manage Rhipicephalus microplus is limited by the emergence of resistance populations. Understanding of resistance mechanisms is essential to develop strategy for sustainable management. The present study was focused on working out the molecular...

Abstract

The problem of ticks and tick borne diseases is a global threat and growing reports of resistance to commonly used insecticides further aggravated the condition and demands for country specific resistance monitoring tools and possible solutions of the problem. Establishment of standard reference is ...

Abstract

Two novel lipase genes RlipE1 and RlipE2 which encoded 361- and 265-amino acid peptides, respectively, were recovered from a metagenomic library of the rumen microbiota of Chinese Holstein cows. A BLAST search revealed a high similarity (90%) between RlipE2 and a carboxylesterase from Thermosinus...

Abstract

This study was done with the objective of developing a methodology for cholinesterase and carboxylesterase expression measurement in acaricide resistant R. microplus, for that purpose the expression levels for these enzymes were measured by real time PCR quantification of mRNA specific detection,...

Abstract

Predicted bovine carboxylesterase (CES) protein and gene sequences were derived from bovine (Bos taurus) genomic sequence data. Two bovine CES1 genes (CES1.1 and CES1.2) were located on chromosome 18 encoding amino acid sequences that were 81% identical. Two forms of CES1.2 were also observed...

Abstract

Chemical control based on the use of pyrethroid and organophosphate compounds has selected resistant genotypes in populations of Rhipicephalus (Boophilus) microplus. Point mutations in esterase-encoding genes represent one of the main resistance mechanisms in this species. In this study, the...

Abstract

This paper reviews the current status and mechanisms of resistance to commonly used acaricides in Mexican strains of the southern cattle tick, B. microplus. Resistance to organophosphates (OPs) and pyrethroids was measured using the FAO Laval Packet Test (LPT), and a modification of the FAO-LPT was ...
