In the present study, findings regarding parasites discovered in a white-tailed deer, Odocoileus virginianus peruvianus, captured in the dry forest of the Paccha district, Chota province, Cajamarca department, are reported. The Servicio Nacional Forestal y de Fauna Silvestre recovered parasites from an adult male specimen and forwarded them to the Tropical Medicine Research Center at the Universidad Nacional de Cajamarca for taxonomic identification of helminths and arthropods, as well as coproparasitological analysis. Two metacestodes corresponding to Cysticercus tenuicollis were identified. Qualitative coproparasitological analyses revealed Nematodirus spp. eggs at a concentration of 10 eggs per gram of feces (EPG) and 40 EPG of Strongylid type that could not be differentiated due to low counts in the coproculture. No trematode eggs were detected in the sedimentation. Among ectoparasit...

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...

The aim of this study was to determine the prevalence of trematodes and nematodes through the presence of eggs in faeces of creole donkeys marketed in the Plaza Pecuaria Iscoconga in Cajamarca, Peru. The work was carried out between November and December 2019 with stool samples from 73 donkeys of both sexes. The samples were analysed using the Sedimentation method modified by Rojas and Torrel for the case of trematodes and the Sheather method for the case of nematodes. All samples were positive for at least one species of parasite. The prevalence found were Fasciola hepatica 28.8 ± 10.4% (21/73), paramphistomides 0%; Strongylus spp 53.4 ± 11.4% (39/73), Trichostrongylus spp 46.6 ± 11.4% (34/73), Nematodirus spp 2.7 ± 3.7% (2/73) and Parascaris spp 2.7 ± 3.7% (2/73). It is concluded that the prevalence of parasitosis was 100%; 98.6% corresponding to nematodes, 27.4% to the associatio...

This study determine the prevalence of Eimeria spp and performs the morphometric study of the oocysts found in the faeces of guinea pigs (Cavia porcellus) from commercial family-rearing farms in the district of Chota, Cajamarca, Peru. The study was conducted between August and October 2014. In total, 285 faecal samples were obtained regardless of sex, age and type of guinea pigs in eight communities. The samples were processed using the Sheather technique and the morphometric study of the oocysts was carried out by microscopic observation at 40X using a micrometric eyepiece with a correction factor of 1.64. Oocyst sporulation was induced with 2.5% potassium dichromate. The prevalence of Eimeria spp was 25%. The average of ovoid-shaped oocysts was 17.46 µm long and 17.25 µm wide and for ellipsoidal oocysts it was 23.40 µm long and 17.8 µm wide. The morphometric characteristics indicat...

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...

The present study evaluated the efficacy of fenbendazole, levamisole and ivermectin in the control of nematodes in dairy cattle farms in three provinces of the Cajamarca region, Peru. Thirty female cattle older than six months were selected in each farm (E-I, E-II, E-III), distributed in three homogeneous groups (n=10) according to the natural infection loads of gastrointestinal nematodes. Using an active principle for each treatment, fenbendazole (oral) and levamisole (subcutaneous) were administered at a dose of 7.5 mg/kg and ivermectin at 0.2 mg/kg (subcutaneous). It was determined that in E-I there was therapeutic failure to fenbendazole (70.05 ± 6.57% efficacy) and levamisole (52.08 ± 7.07%) and in E-II to levamisole (65.06 ± 7.25%) and ivermectin (73.96 ± 6.62%). In E-III, levamisole and fenbendazole were effective (99.13 ± 0.98% and 100%, respectively). The larvae obtained af...

The study determines the prevalence of trematodes through coproparasitology in grazing dairy cattle in six districts of the Cajamarca region. The analyzes and processing of the faecal samples were carried out by natural sedimentation. The proportion of parasitized animals was 50.4 ± 2.1% (1092/2169), only Fasciola hepatica 32.4 ± 2.0% (703/2169), Calicophoron microbothrioides 17.9 ± 1.6% (389/2169) and coinfection by both parasites was 7.51 ± 1.11% (163/2169). The prevalence by district in Cajamarca was 49.5±5.0% (188/380), Baños del Inca 61.2±5.6% (181/296), La Encañada 80.7±4.1% (284/352), Celendín 45.4±5.0% (171 /377), San Juan 50.0±5.0% (190/380) and Chota 20.3±4.0% (78/384). There was no statistical association in the presence of both trematodes in the animals (p>0.95), nor was a correlation found between the altitude of each district and the presence of faecal eggs ...

Chuquiraga weberbaueri “amaro” (Asteraceae) is a plant species popularly used for the treatment of animal fasciolosis in Peru. However, biological and chemical studies of this species remain scarce. Hence, the objective of the present study was to evaluate the anthelmintic effect of the hydroethanolic and aqueous extracts of C. weberbaueri leaves on Fasciola hepatica, through a controlled and a therapeutic efficacy test in artificially infected sheep. In addition, the chemical composition of the extracts was evaluated using phytochemical screening and analysis by UHPLC-MS/MS. Among the evaluated extracts, the aqueous extract proved to be the most efficient and of low toxicity against F. hepatica, inhibiting about 70% of its oviposition, using a 100 mg/kg dose. The chemical study showed that the major constituents were phenolic derivatives, such as chlorogenic acid and ethyl caffeate,...
