The present study aimed to characterize the guinea pig breeding system in three provinces of the Cajamarca Region, Peru. A structured survey was applied to 1231 producers (401 from Cajamarca, 360 from San Marcos and 470 from Cajabamba). The predominant production system is family-commercial (67% of producers). The Peru breed is preferred by producers, rearing the animals in pools. Most of the producers have less than 49 guinea pigs in a 0.5 to 5 ha land area. Alfalfa (Medicago sativa) being the forage most used in the feeding of guinea pigs. More than 80% of producers do not receive technical assistance and more than 87% are not part of a breeder association. In the sanitary characterization, 1 to 5 guinea pigs die per week and per producer, especially in the lactating class. The most reported disease is salmonellosis, which is identified by alterations in the liver.

El presente estudio tuvo como objetivo la caracterización de la crianza de cuyes en tres provincias de la Región Cajamarca, Perú. Se aplicó una encuesta estructurada a 1231 productores (401 de Cajamarca, 360 de San Marcos y 470 de Cajabamba). El sistema de producción predominante es el familiar-comercial (67% de productores). La raza Perú es la preferida por los productores, utilizando mayormente el sistema de crianza en pozas. La mayoría de los productores posee menos de 49 cuyes con un área de terreno entre 0.5 a 5 ha., siendo la alfalfa (Medicago sativa) el forraje más utilizado en la alimentación de los cuyes. Más del 80% de productores no reciben asistencia técnica y más del 87% no forman parte de alguna asociación de criadores. En la caracterización sanitaria, entre 1 y 5 cuyes mueren por semana y por productor, especialmente en la clase lactantes. La enfermedad más...

Fascioliasis, caused by Fasciola hepatica, is a public health problem in Peru, especially in schoolchildren. Prevalence rates in livestock are over 80% in dairy cattle reared in the Andean valley of Cajamarca, Peru. The present investigation aimed to determine the prevalence of F. hepatica infection in schoolchildren and the main risk factors involved in its presentation. Two hundred and seventy schoolchildren nine years old and over from primary public institutions from the district of Los Baños del Inca (Cajamarca) were included in the investigation. Questionnaires were applied to parents and children and fecal samples were taken and evaluated using the rapid sedimentation technique. Blood samples were also collected and analyzed. Seventeen fecal samples were positive to F. hepatica eggs, giving a prevalence of 6.3% (95% CI 3.21 - 9.38). Significant differences were found with origin ...

Fasciolosis caused by Fasciola hepatica is an important parasitic disease of livestock in many countries. In Cajamarca, Peru, prevalence rates above 80% are reported in dairy cattle. The aim of the study was to assess the proliferative capacity and expression of cytokines (IFN-γ and IL-4) in peripheral blood mononuclear cells from cows and calves against nonspecific phytohemagglutinin and specific excretory-secretory antigens from immature and mature stages of F. hepatica. The proliferative capacity was determined by in vitro lymphocyte proliferation and the cytokine expression was evaluated in cell culture supernatants by ELISA. Cows infected with F. hepatica showed a decreased capacity to respond against nonspecific and specific proliferative stimulus. In the cytokine profile against specific stimulus, IFN-γ expression was low while IL-4 response was high, indicating that the respons...

La fasciolosis producida por Fasciola hepatica es una importante enfermedad parasitaria de la ganadería en muchos países. En Cajamarca, Perú, se reportan prevalencias superiores al 80% en el ganado lechero. El objetivo del estudio fue evaluar la capacidad de proliferación y la expresión de citoquinas (IFN-γ e IL-4) en células mononucleares de sangre periférica de terneras y vacas naturalmente infectadas, contra el antígeno no específico fitohemaglutinina y los antígenos específicos de excreción-secreción del estadio inmaduro y maduro de F. hepatica. La capacidad proliferativa fue determinada por linfoproliferación in vitro y la expresión de citoquinas se evaluó en sobrenadantes de cultivo celular por la técnica de ELISA. Las vacas infectadas con F. hepatica mostraron una disminución de la capacidad de respuesta frente a estímulos proliferativos inespecíficos y especÃ...

Se ha adaptado la técnica de extracción de ARN total de Fasciola hepatica, así como la obtención de cDNA mediante RT-PCR con la finalidad de posibilitar la amplificación del gen gst (glutation s-transferasa) de Fasciola hepatica para estudios adicionales sobre la expresión del gen gst en relación a la resistencia de Fasciola hepatica frente al triclabendazol. Esto ha implicado la modificación de las técnicas convencionales para los procesos antes mencionados, lo que ha permitido contar el material genético adecuadamente preparado para amplificar el gen gst mediante PCR convencional. Se trabajó con 11 muestras de parásitos nativos obtenidos del Camal Municipal de la ciudad de Cajamarca. Los resultados obtenidos evidencian que las modificaciones introducidas a los procedimientos convencionales de extracción de ARN y obtención de cDNA son las adecuadas para poder evidenciar ni...

Varroasis is a disease caused by arachnids of the genus Varroa, an obligatory parasite of bees and the cause of high mortality. The present study aimed to report the prevalence of Varroa spp in the apiary of the Fundo Tartar Pecuario of the National University of Cajamarca, Peru and the possible resistance factors associated with the production and temperament of the hives and nuclei. The sampling was carried out in December 2019. The average prevalence of Varroa spp in the four nuclei sampled was 1.62 ± 0.61% and in the three hives it was 1.11 ± 0.5%, being 1.39 ± 0.41% for the apiary. All the nuclei and hives were classified with good production (1 to 2 floors) and in terms of temperament: 1 calm nucleus, 1 aggressive and 2 very aggressive, while the three hives were very aggressive. It is concluded that the quality of being a nucleus or hive does not influence the production or tem...
