Human lagochilascariasis (HL) is a parasite produced by Lagochilascaris minor Leiper 1909 that also can be found in cats and dogs. HL is considered an emerging zoonosis in the Americas, spreading from Mexico to Argentina, and the Caribbean Islands. The present paper describes three HL cases from the Peninsula of Yucatan, Mexico, recorded in the last decade. It describes the characteristics of the lesions and discusses the route of transmission in humans and particularly in the observed patients.

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.

A case of polyparasitism in an 8-year-old female cat from Southern Brazil is reported. Among the described clinical signs, both gurltiosis and lagochilascariasis are of rare occurrence, being categorized as neglected diseases. The diagnosis of feline crural parasitic paraplegia was established through clinical signs, necropsy lesion observations, and the presence of Gurltia paralysans in histological sections of the spinal cord.

The global threat of neglected tropical diseases (NTDs) constitutes a public health issue in underdeveloped countries. Zoonotic helminthiases are the most common human NTD agents in developing countries in sub-Saharan Africa, Asia, and the Americas, causing a global burden of disease that exceeds that of more recognized infectious diseases such as malaria and tuberculosis. Wild canids are well-known mammals that act as natural reservoirs of zoonotic-relevant helminthiasis worldwide, thus playing a pivotal role in their epidemiology and transmission to humans.

Article Synopsis
- A case study details the clinical symptoms and findings of Lagochilascaris minor, a parasitic worm, in a domestic cat from Veracruz, Mexico.
- The cat exhibited a neck fistula containing 32 nematodes, which were identified as Lagochilascaris spp. based on physical characteristics.
- DNA analysis confirmed the species as L. minor, showing a 100% match with samples from Costa Rica, marking the first report of this parasite in domestic cats in Veracruz and highlighting its presence as a zoonotic threat in the region.

Two cases of lagochilascariasis minor in domestic cats from Costa Rica within a period of two months are recorded for the first time in Central America. Clinical findings included purulent discharge and a tumor in the left ear in one of the cats, whereas the other cat had an ulcerated cervical lesion. Both patients underwent surgical procedures during which nematode worms were collected and analyzed.
