En 1970 Tió Y Guerrero, al estudiar los parásitos de Cavia aperea Erxl de las localidades de Canas y Canchis, en el Cuzco, Perú, encontraron que el 28 % de ellos estaban parasitados con Monoecocestus sp. cestodo Anoplocephalideo.

In the present work on helminths parasites of Bufo spinulosus Trifolium (Tschudi) from Huanuco, we found two species, one of they is a new report to Peru.

In 1970 Tió and Guerrero studied parasites of Cavia aperea Erxl from Canchis and Canas in Cuzco, Peru, they found that 28% of C. aperea were parasitized with Monoecocestus sp. cestodo Anoplocephalideo.

En el presente trabajo sobre los helmintos que parasitan a Bufo spinulosus trifolium (Tschudi) de la localidad de Huánuco, se presentan dos especies conocidas para la ciencia pero una de ellas nueva para el Perú.

Information on parasitic helminths of seabirds is very limited in Peru. In the present work, helminths collected from the Belcher's gull (Larus belcheri) from some beaches of Lima (Pucusana, Chorrillos, Ventanilla and Ancón) in Peru were identified. The helminths were studied morphologically and identified as Skrjabinoclava sp. (Nematoda), Contracaecum sp. (Nematoda), Maritrema sp. (Trematoda) and Profilicollis altmani (Acanthocephala). The present work corresponds to the first records of these parasites in the Peruvian gull.

Linguatulosis is a zoonosis caused by Linguatula serrata. The nymph and adult stages of the parasite can affect humans, and the man main mechanisms of transmission is through contact with domestic dogs and ingestion of uncooked infected cattle viscera. This study aimed to determine the prevalence, mean abundance, and the mean intensity of the nymphal stage ofL. serrata in mesenteric lymph nodes of cattle slaughtered in two abattoirs in Lima, Peru. The animals were brought from the departments of Puno, Junín, La Libertad, Amazonas, Pasco and Lima. A total of 3576 lymph nodes from 368 cattle were collected, fat was removed and stored at 5 °C. Nodes with micro abscesses, calcified granulomas and yellow, green or gray nodules were selected and longitudinal cuts were done. Nymphs were fixed and mounted for evaluation. Results of the morphometry showed averages of 4.95 mm total length, 1.39 ...

La linguatulosis es una zoonosis causada por Linguatula serrata, parásito que puede afectar al hombre en su estadio ninfal y adulto, siendo los principales mecanismos de transmisión el contacto con el perro doméstico y la ingesta de vísceras infectadas mal cocidas de bovinos. El presente estudio tuvo como objetivo determinar la prevalencia, abundancia e intensidad media del estadio ninfal de L. serrata en ganglios linfáticos mesentéricos yeyuno-iliacos de reses beneficiadas en dos camales de la ciudad de Lima, Perú, procedentes de los departamentos de Puno, Junín, La Libertad, Amazonas, Pasco y Lima. Se recolectaron 3576 ganglios de 368 animales, se les retiró la grasa circundante y refrigeraron a 5 °C hasta su procesamiento. Se realizaron cortes longitudinales en ganglios con microabscesos, granulomas calcificados o con nódulos de color amarillo, verde o gris. Las ninfas cole...
