Abstract:
Nasopharyngeal myiasis in European roe deer (Capreolus capreolus) is a pathological condition caused by the larval stages of Cephenemyia stimulator, a fly from the Oestridae family. These larvae reside in the host\'s upper respiratory tract for months, inducing significant tissue damage and clinical symptoms. The lifecycle of Cephenemyia stimulator is complex, involving three larval stages before maturation into adult flies, with each stage contributing to the progressive pathology observed in the host. Despite their prevalence, the histopathological effects of these larvae in the nasal and nasopharyngeal cavities have been understudied. Our study fills this knowledge gap by providing a detailed histopathological analysis of the affected tissues, using various staining techniques to reveal the extent and nature of the damage caused by these parasitic larvae. This histopathological examination reveals significant alterations within the nasopharyngeal mucosa and nasal cavity, including erythematous changes, mucosal metaplasia, fibrosis, and tissue necrosis. Parasitic cysts and eosinophilic infiltration further characterize the impact of the infestation, compromising not only the mucosal integrity but also potentially the olfactory function of the affected animals. This research is crucial for understanding the impact of myiasis on both the health and olfactory capabilities of roe deer populations and could have significant implications for wildlife management and conservation.
摘要:
欧洲bee(Capreoluscapreolus)的鼻咽虫病是由头孢霉素刺激器的幼虫阶段引起的病理状况,一只来自Oestridae家族的苍蝇.这些幼虫在宿主的上呼吸道停留数月,诱导显著的组织损伤和临床症状。头孢霉素刺激器的生命周期很复杂,涉及成熟成蝇之前的三个幼虫阶段,每个阶段都有助于在宿主中观察到的进行性病理学。尽管流行,这些幼虫在鼻腔和鼻咽腔中的组织病理学作用尚未得到充分研究。我们的研究通过提供受影响组织的详细组织病理学分析填补了这一知识空白,使用各种染色技术来揭示这些寄生幼虫造成的损害的程度和性质。该组织病理学检查显示鼻咽粘膜和鼻腔内的显着改变,包括红斑改变,粘膜上皮化生,纤维化,和组织坏死。寄生虫囊肿和嗜酸性粒细胞浸润进一步表征了侵染的影响,不仅损害粘膜的完整性,而且可能损害受影响动物的嗅觉功能。这项研究对于了解木虫病对ro种群的健康和嗅觉能力的影响至关重要,并且可能对野生动植物的管理和保护产生重大影响。
