Abstract

Purpose

Gynandromorphism is a developmental anomaly characterized by the simultaneous presence of male and female sexual morphological traits within the same individual. This study documents a case of gynandromorphism in the cattle tick Rhipicephalus microplus(Canestrini 1888) in El Salvador.

Methods

The specimen was collected from a bovine belonging to the Experimental and Practical Station of the Faculty of Agronomic Sciences of the University of El Salvador, located in the municipality of San Luis Talpa, Department of La Paz.

Results

The reported gynandromorph of R. microplus exhibits bilateral gynandromorphism, displaying primarily female characteristics on the left side and male characteristics on the right.

Conclusion

This is the first report of a tick with gynandromorphism in El Salvador. Further studies are warranted to understand the implications of such anomalies and their veterinary and public health relevance.

萨尔瓦多微小棘头蜱（蜱螨亚纲：伊蚊科）雌雄同体现象首次报道。

目的：雌雄同体是一种发育异常，其特征是在同一个体内同时存在男性和女性的性形态特征。本研究记录了萨尔瓦多牛蜱（Canestrini 1888）的一例雌雄同体现象。方法：标本取自位于拉巴斯省圣路易斯塔尔帕市的萨尔瓦多大学农艺科学学院实验与实践站的一头牛。结果：报道的微加鼠雌雄同体表现为双侧雌雄同体，左侧以雌性特征为主，右侧以雄性特征为主。结论：本报告为萨尔瓦多首例雌雄同体蜱虫报告。有必要进行进一步的研究，以了解这种异常的影响及其与兽医和公共卫生的关系。

期刊介绍： Acta Parasitologica is an international journal covering the latest advances in the subject. Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews. The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
