The aim of this study was to estimate the prevalence and burden of gastrointestinal helminths in vicuñas in the district of Contumaza, Cajamarca, as well as to determine their association with the variables of age and sex and to identify the parasitic genera. During August 2015, 208 vicuñas were trapped in the chaccu organized by the peasants and faeces were collected from the rectum. The samples were analysed using the qualitative techniques of flotation with Sheather’s solution and spontaneous sedimentation to detect the presence of helminth eggs and Fasciola hepatica, respectively. The parasite load was estimated using the modified McMaster method. In addition, larvae culture was made with the Baermann technique. The prevalence of helminths was 81.3 ± 5.3% and the prevalence of Strongylus-type eggs, Nematodirus, Trichuris, Capillaria and Moniezia was 61.1, 39.4, 26.9, 16.8 and 8....
