BackgroundThe aim of the investigation was to determine the risk factors for human fascioliasis in schoolchildren in five localities of the Baños del Inca district in Cajamarca, Peru. Secondarily, the prevalence of infection among this population was also studied.MethodsA questionnaire was applied to 270 schoolchildren from 6–12 years of age and to their parents with the aim of collecting information related to risk factors predisposing the children to Fasciola hepatica infection. Faecal samples from all the children were tested for F. hepatica using the modified rapid sedimentation method of Lumbreras and the technique of Kato–Katz for egg counts.ResultsRisk factors were identified as follows—raising cattle, consumption of radishes and chewing grass. The prevalence of F. hepatica in Baños del Inca was 6.30%; there was no significant difference by sex or age.ConclusionRisk factor...

Fasciolosis caused by Fasciola hepatica, is the most prevalent parasitic disease in dairy cattle from the northern region of Cajamarca, Peru. The control of this parasite is based on the use of Triclabendazole (TCBZ), a drug that has been used for more than fifteen years in this area. Recent studies, however, have reported a lack of clinical efficacy after treating dairy cattle. This research was aimed to determine the efficacy of TCBZ in a clinical trial. Eleven dairy cows all positive to F. hepatica identified by presence of eggs in feces, were treated with TCBZ (Fasinex® 10%) at 12 mg/kg body weight. Fourteen and thirty days after treatment, the animals were analyzed for F. hepatica eggs in their feces by the fecal egg count reduction test. The results found show an overall efficacy of 31.05% and 13. 63% (14 and 30 days post treatment, respectively). Furthermore, an in vivo efficacy ...

La temprana caracterización de la fibra de alpaca es esencial para permitir a los criadores seleccionar machos sobresalientes y establecer programas de reproducción adecuados. En este trabajo se determinaron las características de la fibra en alpacas Huacaya machos de la provincia de Cajamarca. Las alpacas estudiadas fueron provenientes de dos empresas alpaqueras. Los parámetros evaluados incluyeron la Media del Diámetro de la Fibra (MDF), el Coeficiente de Variación del Diámetro de la Fibra (CVDF), el Índice de Confort (IC), el Índice de Curvatura (ICur) y la Finura al Hilado (FiHi). Estas características se analizaron en relación con la procedencia y la edad de 80 animales de 1 a 3 años de edad, mediante el equipo de Lasercan. La MDF general fue de 22,6µm, el CVDF fue de 22,4%, la FiHi tuvo un valor de 22,3µm, el ICur un valor de 53,3°/mm, y el IC fue de 89,5%. Además, ...

Introducción: Camu-Camu, es un árbol frutal, oriundo de la amazonla sudamericana que crece en las orillas anegables de rlos amazónicos. Pertenece al genero Myrciaria, especie dubia. Presenta una gran importancia nutritiva. Su alto contenido en ácido ascórbico (2780 mg/lOO g de pulpa) le confieren propiedades antioxidantes.Objetivo: Evaluar la toxicidad subaguda (30 días) del Camu-Camu.Material y método: Utilizamos 33 ratas albinas. macho, Holt<;man, distribuidas en 3 grupos equitativos: Grupo I (grupo control), se leadministró agua destilada, Grupo 11 y Grupo 111, se les administró por vía oral el extracto seco de Camu-Camu a las dosis de 100 y 200mg/Kg, respectivamente. Al inicio del experimento (basal), a los 15 y a los 30 días, se determinó: hemoglobina, WBC, urea, albúmina, creatinina, proteínas, GOT, TGP, TGO, en sangre, y peso corporal; además, serealizó el exam...
