Tracer calves were used to assess the seasonality of infections of gastrointestinal parasites in beef cattle extensively raised at a farm in the State of Minas Gerais, Brazil, and Cooperia was the predominant genus in fecal cultures until the calves were 9 months old.

This is the first record of Brazilian molluscs infected with this nematode species, and larvae obtained from A. fulica snails, from São Vicente, state of São Paulo, also showed genetic profiles of this Nematode.
Population dynamics of Lymnaea columella and its natural infection by Fasciola hepatica in the State of Minas Gerais, Brazil
Study of the population dynamics and natural infection of Lymnaea columella by Fasciola hepatica in a low-lying area near Itajubá in the Brazilian State of Minas Gerais found the removal by farmers of aquatic plants from the drainage furrows caused a drastic reduction in this snail population.
Occurrence of Angiostrongylus vasorum in the lungs of the Brazilian fox Dusicyon vetulus.
Angiostrongylus vasorum infection was detected for the first time in eight foxes (Dusicyon vetulus) captured in the south of the State of Minas Gerais, Brazil. Two crossbred dogs were successfully…
The life cycle of Dendritobilharzia anatinarum cheatum, 1941 (Trematoda, Schistosomatidae)
The life cycle of Dendritobilharzia anatinarum was completed experimentally in the laboratory and it was found that sexually mature trematodes are present in the blood vessels of the bird.

It is concluded that infection by A. vasorum in dogs may cause a discrete anemia during the acute phase which is probably regenerative and important hemostatic alterations due to the infection suggest a chronic intravascular consumption coagulopathy.
Predatory activity of the fungi Duddingtonia flagrans, Monacrosporium thaumasium, Monacrosporium sinense and Arthrobotrys robusta on Angiostrongylus vasorum first-stage larvae.

The four isolates of predatory fungi were efficient in the in vitro capture and destruction of A. vasorum L1, confirming previous work on the efficiency of nematophagous fungi in the control of nem atode parasites of dogs and as a possible alternative method of biological control.
Angiostrongylus vasorum (Baillet, 1866) Kamensky, 1905: emergence of third-stage larvae from infected Biomphalaria glabrata snails
The results shown in these experiments suggest that angiostrongylosis could be directly transmitted to the definitive hosts, with implications for the parasite′s life cycle.
Expression of IL-4, IL-10 and IFN-γ in the liver tissue of cattle that are naturally infected with Fasciola hepatica.
The results suggest that the TH2 polarized host immune response previously observed in experimental infection may also be responsible for establishing chronic phase and the maintenance of the natural infection of cattle from endemic areas that are in continuous contact with parasite.
A New Metastrongilid Species (Nematoda: Metastrongylidae): A Lungworm from Akodon montensis (Rodentia: Sigmodontinae) in Brazil

A new species of Angiostrongylus lenzii is described from the pulmonary artery of the wild rodent Akodon montensis Thomas, 1913, collected in the municipality of Teresopólis, Rio de Janeiro State, Brazil and represents the 17th species of the genus and the 2nd in South America as parasites in rodents.
