RESUMEN

Two parasites were collected from the epithelial layer of the tongue mucosa of a brown-nosed coati (Nasua nasua) in an area of Atlantic Forest in Minas Gerais State, Brazil. These were identified as female Gongylonema sp. nematodes, not previously reported in Brazilian wild carnivores.

RESUMEN

This study describes Crenosoma brasiliense (Nematoda, Metastrongyloidea), a new species parasitic in bronchi and bronchioles of Galictis cuja (Molina) (Carnivora, Mustelidae) from Brazil. This species differs from other 11 species of Crenosoma by having a cuticular projection at the distal end of the spicules, forming a prominent blade at the tip of the spicule, a vulval cuticular appendage with a triangular shape and prominent vulval lips. There are no previous records of species of Metastrongyloidea in G. cuja or species of Crenosoma in South America. Therefore, the new species represents the first host record and first geographical record of species of Crenosoma in South America.

RESUMEN

Holotype and paratype of Ascocotyle (Phagicola) rara Arruda, Muniz-Pereira et Pinto, 2002, a heterophyid trematode recently described on the basis of two worms collected by Lauro Travassos in 1921 in the intestine of Ixobrychus exilis (Gmelin) from Brazil, were studied. The morphology of the worms revealed their conspecificity with Ascocotyle (Phagicola) angeloi Travassos, 1928 found in the same host. Both the taxa have a similar length (between 600 and 900 microm) and shape of the body (long pyriform), the long intestinal caeca reaching to the ovarian level, a long posterior muscular prolongation of the oral sucker and the prepharynx, transverse uterine loops situated between the ventral sucker and testes, and the gonotyl with more than 20 digitiform pockets. Consequently, A. (P.) rara is proposed as a junior synonym of Ascocotyle (Phagicola) angeloi.

RESUMEN

Angiostrongylus felineus n. sp. (Nematoda, Metastrongyloidea), parasitic in Puma (Herpailurus) yagouaroundi (É. Geoffroy, 1803) (Carnivora, Felidae) from the municipality of Juiz de Fora, Minas Gerais state, Brazil, is described and illustrated herein. Angiostrongylus felineus n. sp. differs from all congeneric species by having the anterior extremity with accentuated cuticular expansion and by smaller size of spicules. This study describes for the first time a species of Angiostrongylus in a wild Felidae in Brazil.

RESUMEN

We report Dipylidium caninum for the first time in a wild carnivore in Brazil, the crab-eating fox (Cerdocyon thous). Presence of the cestode could be the consequence of anthropogenic expansion into natural habitats of this host, as this parasite has only previously been reported in domestic hosts in Brazil.

RESUMEN

The prevalence of infection and associated pathology induced by two helminth and one protozoan species infecting Brazilian turkeys are reported. The intestinal nematode Heterakis gallinarum appeared with a prevalence of 70% in the infected birds, without gross lesions when not associated to the protozoan Histomonas meleagridis. Histological findings in the ceca were represented by the presence of H. gallinarum worms, intense chronic diffuse inflammatory processes with mononuclear and polymorphonuclear (heterophils) leucocyte infiltrations. The prevalence of the protozoan H. meleagridis associated to H. gallinarum was of 2.5% and microscopic examination revealed a severe inflammatory process in the liver and cecum with the presence of small clear areas with round eosinophilic parasites. Gross lesions were absent in turkeys infected with the renal digenetic trematode Paratanaisia bragai; the parasite was prevalent in 20% of the cases and cross-sections of the kidneys showed a remarkable distension of the collecting ducts with several worms in the lumen. The walls of the ducts presented a discrete heterophilic infiltrate among mononuclear cells.

RESUMEN

This is the first report of a natural infection in the saffron finch Sicalis flaveola (Linnaeus, 1766) captured in Brazil, with the establishment of a new host record for the acuarioid nematode Acuaria mayori Lent, Freitas and Proença, 1945, previously referred in Cyanocorax chrysops (Vieillot, 1818) from Paraguay and Sporophila caerulescens caerulescens (Vieillot, 1823) and C. cyanomelas (Wied, 1821) from Brazil and Myarchus nuttingi (Ridgway, 1883) from Costa Rica.

RESUMEN

A new genus, Oswaldotrema gen. nov. is proposed. Oswaldotrema nacinovici sp. nov. is descibed from Numenius phaeopus Latham, 1790. Differentiation from the other related genera, namely Philophthalmus, Pygorchis, Proctobium, Parorchis, Echinostephila, Cloacitrema, Pittacium, Ophthalmotrema, Skrjabinovermis and Paratrema, was based on morphological characters, mainly on those referring to the body surface, body shape, head, esophagus, pharynx, acetabulum, vitellaria, vitelline reservoir and seminal vesicle.

RESUMEN

The present paper reports acuarioid nematodes recovered from avian hosts. A new species of the genus Schistorophus Railliet, 1916 is proposed based mainly on findings referring to ptilina, spicules and vagina. Ancyracanthopsis coronata (Molin, 1860) Chabaud & Petter, 1959 is referred again in Brazil since its proposition in 1860, from specimens recovered from a Brazilian bird. A revised key to the species of the genus Schistorophus is also presented
