--- Enterocytozoon bieneusi and Giardia duodenalis are considered the most common intestinal parasites found in humans and domestic, captive and wild animals. These pathogens are responsible for causing diarrhea in immunocompromised and immunocompetent individuals. The aim of the present study was to identify E. bieneusi and G. duodenalis genotypes in fecal samples from alpaca crias. Fecal samples were collected from 126 alpaca crias up to 30 days of age from three geographic regions in the highland of Peru (Huancavelica, Cuzco and Puno). The internal transcribed spacer (ITS) region of the rRNA gene of E. bieneusi, and the amplification of the triosephosphate isomerase (TPI) locus of G. duodenalis, were amplified for a nestedPCR. All positives samples were sequenced. Sixty-five crias (51.6%) were found to be PCR positive for E. bieneusi. Ten distinct genotypes of E. bieneusi were found in alpaca cria isolates, six of all isolates belong to novel genotypes (ALP1, ALP2, ALP3, ALP4, ALP5, and ALP6). Five (7.7%) crias were positive to genotype P, four (6.2%) crias were positive to genotype Type IV, two (3.1%) to genotype D, one (1.5%) to genotype Beb6, 48 (73.8%) to genotype ALP1, and five crias were positive each to new genotype (ALP2, ALP3, ALP4, ALP5, and ALP6). Forty-two samples were positive for G. duodenalis. Assemblages A (n=33) and E (n=9) were detected in crias, Assemblage A was the most frequently found in Puno and Huancavelica, while Assemblage E was found in 8 crias in Cuzco and one from Huancavelica. The potential role of E. bieneusi and G. duodenalis in the neonatal diarrhea syndrome of alpaca needs to be seriously considered and further evaluated, although had not association between the presence of parasites and diarrhea. Key words: Enterocytozoon bieneusi, Giardia duodenalis, alpaca, diarrhea, zoonosis.
