Abstract Background The present study aimed to evaluate the effects of different treatment strategies using a new commercial formulation containing pour-on fluralaner on Rhipicephalus microplus infestation in cattle and pastures tropical climate region where up five generations this tick species can occur per year. Methods Forty-five naturally infested were divided into three experimental groups: T01, treated with (2.5 mg/kg) every 42 days; T02, received first Day 0 but next involved weekly...
Abstract Background In Rio Grande do Sul, Brazil, a region with subtropical climate, Rhipicephalus microplus is present in taurine cattle raised for beef and milk. addition, ticks resistant to multiple acaricides are this region. Recently, fluralaner (isoxazoline) was launched on the market. Thus, there need evaluate effects of control R. cattle. occurrence myiasis by Cochliomyia hominivorax larvae after tick parasitism weight gain during experimental period were evaluated. Methods Thirty...
Abstract Background In 2022, fluralaner was launched on the market for use in control of cattle tick Rhipicephalus microplus after showing 100% efficacy registration trials against causative agents fever (TFAs). The aim present study to determine whether a strategic regimen R. using (FLU) Holstein calves grazing tropical region would alter enzootic stability status fever, triggering outbreaks these animals up 22 months age. Methods this study, group treated with FLU compared currently being...
Abstract Background The occurrence of higher winter temperatures in Brazilian areas with tropical and highland climates may result a fifth peak tick populations during addition to the four generations previously described. Therefore, strategic control protocol was developed treatments two seasons objective controlling ticks that occur spring/summer those autumn/winter. Methods study conducted Mato Grosso do Sul, Brazil, from beginning rainy season, November 2020, October 2021. In randomized...
Abstract Background The first isoxazoline-based acaricide (fluralaner) for the control of Rhipicephalus microplus was introduced onto market in 2022, initially Brazil, followed by other Latin American countries . Therefore, it is important to establish laboratory methods monitor susceptibility populations R. this molecule and determine relationship between results tests those from field trials. Methods A larval immersion test (LIT) performed on 18 lethal concentration 50 (concentration...
Rhipicephalus (Boophilus) microplus is one of the most successful ticks infesting cattle around world. This highly-invasive species transmits parasites that cause fever leading to a high socio-economic burden. Tick eradication programs have often failed, due development acaricide resistance. Here we characterize resistance in large number tick isolates from regions South Africa (KwaZulu Natal, Mpumalanga, Western & Eastern Cape provinces) and two Brazilian regions. By means Larval Packet...
This is the first case of African horse sickness (AHS) in a dog where there was no apparent ingestion meat. Significantly, part colony that resides Good Clinical Practice and Laboratory accredited facility complete history, weather feeding records are maintained. The died after week-long illness despite therapy. principal post-mortem findings were severe hydrothorax pulmonary consolidation (red hepatisation lungs). Histopathology revealed oedema congestion lungs, hyaline degeneration...
The susceptibility of the larval offspring engorged female Boophilus decoloratus, and females, collected from cattle on dairy farms Brycedale, Sunny Grove Welgevind in Eastern Cape Province, South Africa, was tested against acaricides amitraz, chlorfenvinphos cypermethrin. Resistance determined by means Shaw Larval Immersion Test (SLIT) for larvae Reproductive Estimate (RET) Egg Laying (ELT) adults. At Brycedale tests all indicated resistance to chlorfenvinphos, RET ELT amitraz emerging...
