A study in goats was carried out in the central coast of Peru to validate the FAMACHA© method for selective anthelmintic treatment in dairy goat herds. Blood and fecal samples were taken from 120 adult goats in five dairy goat farms. The micro haematocrit and the McMaster techniques plus faecal culture were used to evaluate the haematocrit, faecal nematode egg count (EPG) and to identify major nematode species, respectively. Spearman correlation coefficients were obtained. Two FAMACHA© criteria were used to identify animals that require anthelmintic treatment: 1: score 3, 4 or 5; 2: score 4 or 5, with <20% haematocrit in both cases. Sensitivity, specificity, positive predictive value and negative predictive value were assessed. Bunostomum sp and Haemonchus contortus were identified. Correlations between FAMACHA score, haematocrit and EPG were highly significant (p<0.001). False n...

The aim of this study was to determine the effectiveness of a combination of albendazole and rafoxanide against Fasciola hepatica in cattle from the northern region of Lambayeque fattened in an intensive fattening centre in Lima, Peru. Twenty-one naturally infected bulls treated with a combination of albendazole (9 mg/kg) and rafoxanide (10 mg/kg) (Ranide Forte®, TQC, Peru) were used. The effectiveness of the drug was determined using the faecal egg count reduction test (FECRT) with faecal samples collected on days 14 and 30 of dosing. The number of eggs per gram of faeces (epg) was determined with the FLUKEFINDER® method. The bootstrapping method in the R program was used to generate the 95% confidence intervals. The efficacy of the compound was 94% (90:98 95% CI) on day 14 and 100% on day 30. It is shown that rafoxanide in combination with albendazole is a good therapeutic option aga...

La giardiasis canina, parasitosis causada por Giardia sp., es un problema de gran impacto en la salud canina reconocida en todo el mundo por ser causa de trastornos digestivos, sobre todo en animales jóvenes y además de ser reconocido el potencial riesgo zoonótico que involucra mencionándose la posibilidad de que la giardiasis canina sea reservorio en la epidemiología de la giardiasis humana. El objeto del presente estudio fue determinar la prevalencia de Giardia sp. en caninos domésticos en el Cono Sur de la cuidad de Lima, Perú. Para tal fin se recolectaron 204 muestras de heces de caninos domésticos procedentes de los distritos de Surco, Barranco, Chorrillos, San Juan de Miraflores, Villa Maria del Triunfo y Villa El Salvador, estratificados según el nivel socioeconómico de los propietarios. Las muestras se analizaron mediante las Técnicas de examen directo y Sedimentación...

The aim of this study was to determine the prevalence and monthly parasitic load of gastrointestinal nematodes and Fasciola hepatica in dairy cattle of the districts Nueve de Julio and Matahuasi el Mantaro Valley (Junín, Peru), as well as the epidemiological factors associated with these parasitosis. Monthly faecal samples were collected from 11 dairy farms in each district for one year. The samples were analysed with the modified Dennis technique for the detection and counting of F. hepatica eggs and the modified McMaster technique for nematode eggs. The mixed logistic regression test was used to evaluate the variables district, time of year, feeding system, age, temperature, rainfall and humidity as possible risk factors. The average monthly prevalence in Matahuasi and Nine of July for gastrointestinal nematodes was 24.5 and 30.3%, with monthly loads of 118.3 and 87.4 hpg, and for F. ...

This study assessed the prevalence and risk factors associated with gastrointestinal parasite infection in goats in Ayacucho, Peru. Fecal samples were collected from a total of 254 goats from four districts of Ayacucho: Ocaña (89), Colca (76), Pacaicasa (64), and Luricocha (25) during the dry season; recording the location, sex, and age of the animals. The fecal samples were analyzed using the flotation technique in salt and sugar solution, and modified McMaster egg counting techniques for eggs/oocysts (epg/opg) of gastrointestinal parasites. The associations between location, sex, and age with the prevalence of gastrointestinal parasites were analyzed using the chi-square test. Fecal samples showed an overall parasite prevalence of 87.80%. The identified parasites were Eimeria spp. (86.22%), Strongyle type eggs (STE) (65.75%), Skrjabinema spp. (7.87%), Trichuris spp. (3.15%) and Moniez...

El objetivo del presente estudio fue evaluar la presencia de huevos de helmintos en heces de hámsteres (Mesocricetus auratus y Phodopus sungorus) criados como mascotas para su venta en tiendas del Cercado de Lima, Perú. El estudio fue descriptivo, transversal y prospectivo. Se evaluaron heces de 63 grupos (‘pools’) de hámsteres de cuatro tiendas locales con la técnica de concentración coproparasitológica de flotación usando la solución de azúcar-sal, durante los meses de mayo a julio de 2021. Los huevos de helmintos fueron identificados según su dimensión y morfología. Se identificaron huevos de helmintos en el 60.5 y 36% de los ‘pools’ de hámster sirio (M. auratus) y hámster ruso (P. sungorus), respectivamente. Syphacia spp fue el parásito que se halló en mayor frecuencia (36.5%), seguido de Aspiculuris tetraptera (7.9%). Hymenolepis spp fue el único cestodo y p...

(3.15%) and Moniezia spp. (3.15%). There was no significant association between the location and the presence of parasites (p<0.05), however, there was a higher prevalence and parasite variety in Luricocha. Sex and age did not have a significant association with parasitosis (p>0.05), except in prevalences of Trichurisspp....

Objective: The study assessed the anthelmintic activity of Artemisia absinthium ethanolic extract for controlling gastrointestinal nematodes in goats, both in vitro using infective larvae and in vivo in naturally infected goats under free-grazing conditions in the region of Ayacucho, Peru. Materials and Methods: For the in vitro assay, a larval motility inhibition test was performed on Trichostrongylus spp. infective larvae from goats using three different dilutions: 150, 175, and 200 mg/ml of the plant extract. In vivo efficacy was evaluated through the fecal egg count reduction test (FECRT), which was applied to 15 naturally infected Creole goats in one community. Animals were randomly assigned to 3 experimental groups and treated orally with 600 mg/kg of the plant extract. Fecal samples were collected directly from the rectum on days 0 (pre-treatment) and 7 and 15 post-treatment for e...

El objetivo del presente estudio fue aislar e identificar a Leishmania de Amblyomma naponense y Amblyomma humerale colectadas de Pecari tajacu, Tayassu pecari y Chelonoide denticulata. Se colectaron garrapatas Amblyomma naponense y Amblyomma humerale de Pecari tajacu, Tayassu pecari y Chelonoide denticulata en Madre de Dios, Perú. Se extrajeron las vísceras y glándulas salivales de las garrapatas y se hicieron observaciones directas al microscopio, se realizaron cultivos en agar sangre bifásico y se inocularon en almohadillas plantares e intraperitoneal de hámsteres. En ninguna de las observaciones, cultivos y respuesta a las inoculaciones se aisló ni identificó al parásito. Estos resultados muestran una investigación básica la cual sirve para recomendar el uso de un número mayor de garrapatas colectadas de varios animales como potenciales reservorios de Leishmania y el uso de...
