Abstract:
Jaguarundi (Puma yagouaroundi), feeds on birds, small mammals, reptilians, fishes and
arthropodae which are potential intermediate hosts and/or paratenic for parasites. The
endoparasites may infect wild felines with theses animals typically showing no evidence of
medical signs, excepting when a significant infection exists or the animal presents a state of
imunosuppression. Considering this problematic, two cases of Cylicospirura spp. infection in
jaguarundi (P. yagouaroundi) were investigated, both of them reported in the semiarid region
of Paraíba. Two specimens of jaguarndi were found dead in province of Paraíba’s highways
demonstrating traumatic lesions caused by automobiles, having them transported and
analysed in the Laboratório de Patologia Animal at UFCG. Through necropsy procedures,
multiple fractures and inner organs disruptions were observed due to the vehicles’ shocks;
also, whitish nodes were found, varying from 1 to 2 cm in diameter, featuring a solid
consistency at the serous surface which extended to the muscular layer and stomach’s
mucosa, with nematodes specimina found in their lumen. Similar lesions were observed in the
small intestine as well as in the animal’s lungs. In a microscopical analysis, the nodes showed
a composition made, in a major portion, of granulomatous inflammatory infiltrate, forming
multiples granulomata circled by an accentuated fibrous connective tissue in both stomach
and small intestine. At the centre of these granulomata, circular structures that are compatible
with pseudocelom nematodes were found, presenting few eosinophilic fluid, thin coelome
musculature, abundant lateral strings, circular and vacuolated, large intestines, high cubic
epithelium with basilar guidance centers and presence of eosinophilic amorphous material
inside. There were also interstitial pneumonia with analogous by injuries nemotades; such
morphological traits are known to be related to Cylicospirura spp., which induced the
formation of numerous granulomata, causing eosinophilic sclerosing fibroplasia on stomach,
discreet enteriris and interstitial pneumonia. The Cylicospirura spp. infection occur in wild
gatos-mouriscos (Puma yagouaroundi) in the Brazilian Northeastern semiarid, yet diagnosed
through an accidental finding upon necropsy procedures in runned-over animals. The
presence of Cylicospirura spp. in the lungs of one of the animals is considered an unusual
observation since this organism usually infects organs of the digestive system and, depending
on the amount of parasites, may cause the death of native felines.
