Abstract

The presence of Oestrus sp. in sheep is a parasitic condition that has been widely reported in most regions of the world. However, to date, there are no documented records of this parasitosis in the Azores archipelago, Portugal. This study describes the first occurrence of Oestrus sp. in a sheep on Terceira Island, Azores, identified during necropsy, with the animal showed signs of lethargy, anorexia and loss of body condition before death, which may have resulted from multiple factors rather than exclusively from Oestrus sp. Infestation.

During the post-mortem examination, five Oestrus sp. larvae were found in the animal's nasal cavities and paranasal sinuses. This finding confirms the presence of this parasite on Terceira Island, suggesting a possible recent introduction or under-reporting of its occurrence in local sheep.

亚速尔群岛绵羊鼻腔内发情期蝇幼虫的报告

绵羊中存在的发情期是一种寄生疾病，在世界上大多数地区已被广泛报道。然而，迄今为止，在葡萄牙亚速尔群岛没有这种寄生虫病的文献记录。本研究描述了首次在亚速尔群岛Terceira岛的一只羊身上发现的发情虫，该动物在死亡前表现出嗜睡、厌食和身体状况丧失的迹象，这可能是由多种因素造成的，而不仅仅是发情虫的侵扰。在尸体解剖过程中，在该动物的鼻腔和鼻窦内发现了5只发情雌蚊幼虫。这一发现证实了该寄生虫在Terceira岛上的存在，这表明可能是最近引入的，或者在当地绵羊中出现的报告不足。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
