The paramfistomosis is an infection caused by a trematode belonging to the sub order Paramphistomata, some their species are parasitics of the rumen and reticulo of ruminant. One of the most frequent trematodos in the world is Cotylophoron, it affects to domestic and wild ruminant, especially cows, sheep, goats and buffalos in tropical and subtropical regions. We evaluate the parasitism in 61 specimens of apparently healthy cattle (42 adult females and 19 under one year), fed with wild pastures on a farm located on the Nanay River Basin, Iquitos. The samples of fresh grounds were obtained by means of rectal palpation and processed by means of the method of Dennis modified. Two cows were sacrificed to collect mature parasites. The results indicate the presence of Cotylophoron cotylophorum (Fischoeder, 1901) Stiles & goldeberger, 1910, in the studied animals, which is a new record from...

Many Amazonian animals are a valuable food source, for the rural and urban people of the Peruvian forest. Their meat is called carne de monte, and is the third source of protein food in the region. Podocnemis unifilis (Yellow-spotted Amazon River turtle or taricaya) is utilized for both its meat and eggs. The efforts for restocking this reptile through breeding in semicaptivity and captivity, has allowed increasing the population, and now they are abundant. However, the breeding process had not taken into account the sanitary aspect, and this information is barely known in Peru. With the objective of identifying the parasitic fauna of the taricaya, the digestive tracts of 12 females (2 adults, 10 young) captured in the Pacaya Samiria National Reserve where examined. Different grades of parasitic infection were found in all turtles investigated. The parasites identified were the nematodes...

La paranfistomosis es una infección ocasionada por trematodes pertenecientes al suborden Paramphistomata, algunas de estas especies son parásitos del rúmen y retículo de rumiantes. Uno de los trematodos más fre- cuentes en todo el mundo es el Cotylophoron que afecta a rumiantes domésticos y silvestres, especialmente a vacas, ovejas, cabras y búfalos especialmente en regiones tropicales y subtropicales. Se realizó la evaluación parasitaria a 61 ejemplares de ganado bovino aparentemente sanos (42 hembras adultos y 19 menores de un año), manejados al pastoreo, en un fundo ganadero ubicado en la cuenca del río Nanay –Iquitos. Las heces fueron obtenidas mediante palpación rectal y procesada mediante el método Dennis modificado. Dos vacas fueron sacrificadas para obtener parásitos adultos. Los resultados indican la presencia de Cotylophoron cotylo- phorum (Fischoeder, 1901) Sti...

Muchos animales amazónicos son apreciados como alimento por los pobladores rurales y urbanos de la selva peruana; su carne se le conoce como carne de monte y es la tercera fuente de alimento proteico en la región. La tortuga Podocnemis unifilis conocida como taricaya es una especie de la que se consume la carne y huevos. Los esfuerzos para el repoblamiento de esta especie mediante cría en semicautiverio y cautiverio, han permitido el incremento de la población y como consecuencia en la actualidad son abundantes. Sin embargo, el manejo no ha contemplado el aspecto sanitario, y esta información es poco conocida en el Perú. Con el objetivo de identificar la fauna parasitaria de la taricaya, se realizó el análisis del contenido gastrointestinal de 12 hembras (2 adultos, 10 juveniles), capturadas en la Reserva Nacional Pacaya Samiria. Encontramos diferentes grados de infección parasi...

In this paper, Mecistocirrus digitatus (Linstow, 1906) Railliet and Henry, 1012 a nematode Trichostrongylidae is reported in the fi rst time from Loreto, Peru.

En el presente trabajo se reporta, por primera vez en el Perú, la presencia del nemátode Trichostrongylidae Mecistocirrus digitatus (Linstow, 1906) Railliet and Henry, 1912, encontrado en vacunos de Loreto, Perú.

We obtained 8 digestive tract of the turtle Podocnemis expansa and 18 of P. unifilis from the Belen market (Iquitos, Peru). Only digeneans were studied and identified. Four species were found: Nematophila grandis (Diesing, 1839) Travassos, 1934, Halltrema avitellina Lent & Freitas, 1939, Podocnemitrema papillosum Alho & Vicente, 1964 and Telorchis hagmanni Lent & Freitas, 1937. Halltrema avitellina, Podocnemitrema papillosum and Telorchis hagmanni are new records from Peru.

En el mercado de Belén (Iquitos, Perú) se obtuvieron ocho tractos digestivos de Podocnemis expansa y 18 de P. unifilis los que fueron analizados en búsqueda de parásitos, detectándose la presencia de digeneos y nematodos. Solo se estudió los digeneos, los que fueron identificados como Nematophila grandis (Diesing, 1839) Travassos, 1934, Halltrema avitellina Lent & Freitas, 1939, Podocnemitrema papillosum Alho & Vicente, 1964 y Telorchis hagmanni Lent & Freitas, 1937. Halltrema avitellina, Podocnemitrema papillosum y Telorchis hagmanni son nuevos registros para el Perú.

In this paper, we report the results of parasitological examination performed on 40 specimens of marsupials species: Caluromys lanatus, Didelphis marsupialis, Marmosops noctivagus, Metachirus nudicaudatus, Marmosa (Micoureus)regina, Monodelphis adusta, Philander andersoni and Philander opossum from department of Loreto, Peru. The endoparasites were: Nematoda: Aspidodera sp., Cruzia tentaculata, Physaloptera mirandai, Physaloptera sp., Pterygodermatites sp., Trichuris sp., Turgida turgida, and Viannaia sp.; Trematoda: Podo- spathalium pedatum; Acanthocephala: Giganthorhynchus ortizi and Pentastomida: nymph. For the first time Trichuris sp., Pterygodematities sp., Turgida turgida, Viannaia sp. and Podospathalium pedatum are reported from marsupials in Peru. Also, for the first time the following parasite-hosts associations are recorded: Pterygo- dermatites sp.-Marmosa regina, Viannaia sp.-...

The aim of this study was to identify and determine the presence of blood parasites in yellow-footed tortoises sold in the market of Belen, Iquitos, Peru and their association with sex, body weight, hematocrit and parasitemia. Blood samples were collected from 47 tortoises in July 2010. The thin blood smears with Giemsa, the microcapillary Woo technique and the Buffy coat technique were used for the identification of the haemoparasites. The results showed the presence of Haemogregarina sp in 74.5% of the samples, being 68.8% in females and 86.7% in males. There were mature gamonts (11.09 ± 1.42 μm length x 5.82 ± 0.76 μm wide) and inmature gamonts (14.85 ± 0.69 μm x 3.26 ± 0.41 μm). There were no significant differences between the presence of the parasite and the variables sex, weight, hematocrit and parasitemia level.
