Three rat liver nucleotides(5') diphosphosugar (NDP-sugar) or nucleoside(5') diphosphoalcohol pyrophosphatases are described: two were previously identified in experiments measuring Mg(2+)-dependent ADP-ribose pyrophosphatase activity (Miró et al. (1989) FEBS Lett. 244, 123-126), and the other is a new, Mn(2+)-dependent ADP-ribose pyrophosphatase. They are(More)
Taking into account the difficulties of taxonomic identification of larval anisakid nematodes based on morphological characters, genetic analyses were performed, together with those usually applied, in order to identify anisakid larvae found in the flounder Paralichthys isosceles from the littoral of the state of Rio de Janeiro, Brazil. The analysis of(More)
Data on the frequency, distribution and mean intensity of the helminth fauna recovered from outbred and inbred mice conventionally maintained in Brazilian animal houses, are reported. The oxyurid nematodes Syphacia obvelata and Aspiculuris tetraptera presented overall frequencies of 91.5% and 8.5%, respectively. The frequency of S. obvelata in animals of(More)
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(More)
This investigation reports data on frequency and pathology related to the nematode Cheilospirura hamulosa in 28 ring-necked pheasants (Phasianus colchicus) and 30 domestic chickens (Gallus g. domesticus) from backyard flocks of five localities of the State of Rio de Janeiro, Brazil. The prevalence of C. hamulosa in pheasants was of 14.3%, with a mean(More)
New records for nematode species recovered from elasmobranch fishes in Brazil are established and new systematical arrangements proposed. Parascarophis sphyrnae Campana-Rouget, 1955 from the spiral valve of Sphyrna zygaena is referred for the first time in South America as a new host record. Procamallanus (S.) pereirai Annereaux, 1946, from the spiral valve(More)
New records for helminth species recovered from elasmobranch fishes in Brazil are established. Digenean and acanthocephalan parasites of elasmobranch fishes are reported from the southern coast of Brazil: Otodistomum veliporum (Creplin, 1837) Stafford, 1904 (Digenea: Azygiidae) in the stomach and spiral valve of Dipturus trachydermus and in the spiral valve(More)
During recent studies of the parasites of rodents from Goiás and Bahia States, the following nematodes were recovered: Aspidodera vicentei n.sp., Boreostrongylus minutus (Dujardin, 1845) Durette-Desset, 1971, Hassalstrongylus epsilon (Travassos, 1937) Durette-Desset, 1971, Hassalstrongylus hoineffae (Durette-Desset, 1969) Durette-Desset, 1971,(More)
Sixty specimens of Paralichthys isosceles captured in the southeastern Brazilian coast were investigated for helminths from October 2006 to March 2008. One thousand eight hundred and twenty larvae (third and fourth stages) of Hysterothylacium sp. were recovered from the abdominal cavity, free or inserted in the mesentery, intestine, stomach, stomach wall,(More)
