Objective: To analyze the presence of protozoan parasites in bird coprolites from the Tremembé Formation (Oligocene of the Taubaté Basin).

Materials: Twenty avian coprolites embedded in pyrobituminous shale matrices.

Methods: Samples were rehydrated and subjected to spontaneous sedimentation.

In the present study, we describe Oxysomatium brevispiculum n. sp. (Ascaridida: Cosmocercidae) parasitizing Amphisbaena alba Linnaeus (Squamata: Amphisbaenidae) in the municipality of Uberlândia, Cerrado Biome, Minas Gerais, Brazil.

The aim of this study was to register the first occurrence of Synhimantus (Dispharynx) nasuta (Nematoda: Acuariidae) in some species of wild birds in Brazil. In addition, the aim was to deepen the knowledge about the morphology of this species through analysis using scanning electron microscopy. Nematodes were collected in wild birds of the species Turdus leucomelas, T.

Parasites have evolved a diversity of lifestyles that exploit the biology of their hosts. Some nematodes that parasitize mammals pass via the placenta or milk from one host to another. Similar cases of vertical transmission have never been reported in avian and nonavian reptiles, suggesting that egg laying may constrain the means of parasite transmission.

During the past twenty years, a number of molecular analyses have been performed to determine the evolutionary relationships of Onchocercidae, a family of filarial nematodes encompassing several species of medical or veterinary importance. However, opportunities for broad taxonomic sampling have been scarce, and analyses were based mainly on 12S rDNA and coxI gene sequences. While being suitable for species differentiation, these mitochondrial genes cannot be used to infer phylogenetic hypotheses at higher taxonomic levels.

Physaloptera bainae n. sp. (Nematoda: Physalopteridae) from stomach of the large "tegú" lizard Salvator merianae (Squamata: Teiidae), collected in an ecological park that is part of the Atlantic Rainforest biome in Juiz de Fora, Minas Gerais, Brazil, is described.

Wolbachia are vertically transmitted endosymbiotic bacteria of arthropods and onchocercid nematodes. It is commonly accepted that they co-evolved with their filarial hosts, and have secondarily been lost in some species. However, most of the data on the Wolbachia/Onchocercidae relationship have been derived from studies on two subfamilies, the Dirofilariinae and the Onchocercinae, which harbour parasites of humans and domestic animals.

Background: Wolbachia are intriguing symbiotic endobacteria with a peculiar host range that includes arthropods and a single nematode family, the Onchocercidae encompassing agents of filariases. This raises the question of the origin of infection in filariae. Wolbachia infect the female germline and the hypodermis.

During the study of the metazoan parasites of Paroaria dominicana (Linnaeus, 1758), eight infrapopulations of Mediorhynchus emberizae (Rudolphi, 1819), were collected in the medium third of the small intestine, with parasite intensities ranging from one to ten specimens. Differences among the average values of the biomass, volume of the eggs, volume of the testicles and the parasite density of the infrapopulations were statistically tested in order to detect variations of these parameters in function of parasite density. Was observed that the acanthocephalans biomass increased with the volume of the intestine and also that the parasite density increased with the parasite intensity in the infrapopulations.

During the study of the metazoan parasites of Paroaria dominicana Linnaeus, 1758 (Passeriformes), four infrapopulations of Platynosomum illiciens (Brown, 1901) (Trematoda), parasitic in the liver ducts were collected, with intensity of infection 10, 11, 18 and 36 specimens respectively. Differences between the means of morphometrical values and the total number of eggs were statistically tested. The liver weigh were not significantly correlated with avian total weigh and length, and with the total parasitic abundance.
