Resumo: | The aim of the present study was to evaluate the hemolymph of engorged females of Rhipicephalus microplus ticks exposed to the growth regulator fluazuron. Firstly, the engorged females were divided into two groups (control and treated) and these were subjected to an immersion test. Hemolymph was collected 24 and 48 hours after the immersion test, to evaluate the cellular and metabolic response. In comparison with the control group, the treated group had lower total hemocyte counts at both times, with lower granulocyte counts and higher spherulocyte counts. There were reductions in glucose and total protein values in both the control and the treated group at the 48-hour evaluation, compared with the 24-hour evaluation. There were no changes in activity levels of lactate dehydrogenase and aspartate aminotransferase enzymes in either group at both times. Fluazuron was not able to promote changes in the energy metabolism of the ticks under the conditions established for this study, but this growth regulator proved to be capable of promoting changes in hemocyte dynamics. |

Primeiramente, as fêmeas ingurgitadas foram divididas em dois grupos (controle e tratado) e estes foram submetidos a um teste de imersão. A hemolinfa foi coletada 24 e 48 horas após o teste de imersão, para avaliação da resposta celular e metabólica. Em comparação com o grupo controle, o grupo tratado apresentou menor contagem de hemócitos totais em ambos os momentos, com menor contagem de granulócitos e maior contagem de esferulócitos. Houve reduções nos valores de glicose e proteína total no grupo controle e no grupo tratado na avaliação de 48 horas, em comparação com a avaliação de 24 horas. Não houve alterações nos níveis de atividade das enzimas lactato desidrogenase e aspartato aminotransferase em nenhum dos grupos em ambos os momentos. O fluazuron não foi capaz de promover alterações no metabolismo energético dos carrapatos nas condições estabelecidas para este estudo, mas esse regulador de crescimento mostrou-se capaz de promover alterações na dinâmica hemocitária.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2021-11-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdftext/xmlhttps://rbmv.org/BJVM/article/view/122010.29374/2527-2179.bjvm001821Brazilian Journal of Veterinary Medicine; Vol. 43 No. 1 (2021); e001821Revista Brasileira de Medicina Veterinária; v. 43 n. 1 (2021); e0018212527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://rbmv.org/BJVM/article/view/1220/1105https://rbmv.org/BJVM/article/view/1220/1203Copyright (c) 2021 Mariana Silva Revoredo Alves, Andressa Aparecida Lima Reis, Marisa Beatriz da Silva Rocha, Melina Cardilo Campos Alves, Debora Azevedo Borges, Barbara Rauta de Avelar, Diefrey Ribeiro Campos, Yara Peluso Cid, Fabio Barbour Scotthttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAlves, Mariana Silva RevoredoReis, Andressa Aparecida LimaRocha, Marisa Beatriz da SilvaAlves, Melina Cardilo CamposBorges, Debora Azevedode Avelar, Barbara RautaCampos, Diefrey RibeiroCid, Yara PelusoScott, Fabio Barbour2022-06-26T21:40:03Zoai:ojs.rbmv.org:article/1220Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2022-06-26T21:40:03Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false |
