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...

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...

(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....

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...
