Abstract

Ectoparasites are important to the one health concept because their parasitism can result in the transmission of pathogens, allergic reactions, the release of toxins, morbidity, and even death of the host. Ectoparasites can affect host physiology, as reflected in immune defenses and body condition as well as hematological and biochemical parameters. Thus, evidence that ectoparasites influence host hematological parameters was systematically reviewed, and the methodological quality of these studies was analyzed. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed, and the studies included were limited to those that evaluated changes in hematological tests in ectoparasite-infested and non-infested animals, and bias and methodological quality were evaluated using the Animal Research: Reporting of In Vivo Experiments guideline. Thirty-four studies were selected and information about the host, ectoparasite infestation, blood collection, and analysis was collected and compared whenever possible. In this review, the presence of ectoparasites influenced both the red series and the white series of hematological parameters. Among the main parameters analyzed, hematocrit, red blood cells, hemoglobin, and lymphocytes showed reductions, probably due to ectoparasite blood-feeding, while including eosinophils, neutrophils, and basophils increased in infested animals due to the host immune response. However, methodologic improvements are needed to reduce the risk of bias, enhance the reproducibility of such studies, and ensure results aligned with the mechanisms that act in the ectoparasite-host relationship.

体外寄生虫影响宿主血液学参数的证据:系统综述。
外寄生虫对一个健康概念很重要,因为它们的寄生会导致病原体的传播、过敏反应、毒素的释放、发病甚至宿主的死亡。外寄生虫可以影响宿主的生理机能,这反映在免疫防御和身体状况以及血液学和生化参数中。因此,系统地回顾了体外寄生虫影响宿主血液学参数的证据,并分析了这些研究的方法学质量。遵循系统评价的首选报告项目和荟萃分析指南,所包括的研究仅限于评估体外寄生虫感染和未感染动物血液学测试变化的研究,并使用动物研究:体内实验报告指南评估偏倚和方法学质量。选择了34项研究,尽可能收集并比较了有关宿主、体外寄生虫感染、血液采集和分析的信息。在这篇综述中,体外寄生虫的存在影响了血液学参数的红色系列和白色系列。在分析的主要参数中,红细胞压积、红细胞、血红蛋白和淋巴细胞显示减少,可能是由于外寄生虫的血液喂养,而包括嗜酸性粒细胞、中性粒细胞和嗜碱性粒细胞在内的受感染动物由于宿主免疫反应而增加。然而,需要对方法进行改进,以降低偏倚的风险,提高此类研究的可重复性,并确保结果与体外寄生虫-宿主关系中的机制一致。

期刊介绍: Animal Health Research Reviews provides an international forum for the publication of reviews and commentaries on all aspects of animal health. Papers include in-depth analyses and broader overviews of all facets of health and science in both domestic and wild animals. Major subject areas include physiology and pharmacology, parasitology, bacteriology, food and environmental safety, epidemiology and virology. The journal is of interest to researchers involved in animal health, parasitologists, food safety experts and academics interested in all aspects of animal production and welfare.
