Abstract

Lagochilascariasis is a neglected zoonosis that affects domestic and wild mammals, including humans, and can form nodules, especially on the neck. Although emerging, it is considered a rare disease in the Americas and, therefore, the objective was to report an atypical case of recurrent otitis with the formation of polyps in the ear canal in a domestic feline associated with lagochilascariasis in Brazil. A cat had a purulent exudate in one of her ears and responded poorly to treatments. During an otoendoscopy procedure, a polyp and nematodes were removed and sent for histopathological and parasitological diagnosis. Nematodes were subjected to DNA extraction, whose amplification of the 18S, cox1 and 12S genes in the Polymerase Chain Reaction (PCR) and genetic sequencing confirmed the presence of Lagochilascaris minor. To our knowledge, this is the first description of recurrent otitis with the formation of polyps in the ear canal associated with lagochilascariasis in domestic cats and the description of this atypical case may contribute to the elucidation of new clinical cases. Additionally, new molecular sequences are provided, contributing to the knowledge of the parasite.

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).
