dc.description.none.fl_txt_mv The aim of this study was to estimate the prevalence of gastrointestinal helminthiasis in guinea pigs of small-scale farming of Matahuasi district, Concepción province, Junín-Peru, as well as to determine the genera and species of gastrointestinal helminths, load and type of parasitism (monoparasitism, biparasitism or polyparasitism), degree of concordance between the differential count of parasites to post mortem examination vs coprological techniques and the sensitivity/specificity of coprological techniques in the diagnosis of gastrointestinal helminthiasis in guinea pigs. Gastrointestinal tracts of guinea pigs (n=262) were acquired from slaughtering centres between January and March 2017. The stomach, small intestine and large intestine segments were evaluated to determine the parasitic load and faecal samples were collected from the rectum. Sample analysis was performed by differential count of parasites on post-mortem examination and complementary coprological techniques (Flotation and modified Dennis). The prevalence of gastrointestinal helminths was 82.8 ± 4.6%. Paraspidodera uncinata, Capillaria spp, Trichostrongylus axei and Trichuris spp were identified with frequencies of 74, 34, 6.1 and 3.4% respectively. The average number of helminths per animal was 24.7, where P. uncinata, Capillaria spp, Trichostrongylus axei and Trichuris spp showed averages of 23.5, 8.7, 1.2 and 1.2, respectively The monoparasitism was 50.4% and the biparasitism was 30.2% The degree of concordance between the coprological techniques presented values of Kappa (K) equal to 0.19 and 0.13 indicating poor concordance. The Flotation technique and the modified Dennis technique presented a sensitivity of 39.6 and 29.5% and a specificity of 89.9 and 93.3%, respectively.
El objetivo del estudio fue estimar la prevalencia de helmintiasis gastrointestinal en cuyes de producción familiar-comercial del distrito de Matahuasi, provincia Concepción, Junín-Perú; así como determinar los géneros y especies de helmintos gastrointestinales; carga y tipo de parasitismo (monoparasitismo, biparasitismo o poliparasitismo), grado de concordancia entre el recuento diferencial de parásitos al examen post mortem vs las técnicas coprológicas y la sensibilidad/especificidad de las técnicas coprológicas en el diagnóstico de la helmintiasis gastrointestinal en cuyes. Se adquirieron 262 tractos gastrointestinales de centros de acopio de cuyes provenientes de crianzas familiar-comercial entre enero y marzo de 2017. Se evaluaron los segmentos de estómago, intestino delgado e intestino grueso para determinar la carga parasitaria y se colectaron muestras fecales del recto. El procesamiento de muestras se realizó mediante el recuento diferencial de parásitos al examen post mortem y técnicas coprológicas complementarias (Flotación y Dennis modificado). La prevalencia de helmintos gastrointestinales fue de 82.8 ± 4.6%. Se identificaron Paraspidodera uncinata, Capillaria spp, Trichostrongylus axei y Trichuris spp con frecuencias de 74, 34, 6.1 y 3.4%, respectivamente. El número promedio de helmintos por animal fue 24.7, donde P. uncinata, Capillaria spp, Trichostrongylus axei y Trichuris spp mostraron promedios de 23.5, 8.7, 1.2 y 1.2, respectivamente. El monoparasitismo fue 50.4% y el biparasitismo fue 30.2%. El grado de concordancia entre las técnicas coprológicas presentó valores de Kappa (K) igual a 0.19 y 0.13 indicando que fue del tipo pobre. Las técnicas de flotación y Dennis modificado presentaron una sensibilidad de 39.6 y 29.5% y una especificidad de 89.9 y 93.3%, respectivamente.
