The present work increases the knowledge about the intestinal parasitism of camelids from Cerro Casa de Piedra 7 (CCP7) archaeological site during the last 10000 years. Coprolites assigned to camelids collected from 9 stratigraphic levels were examined. The comparison between new information and from previous studies of CCP7 site showed similar results. There was a recurrence of certain intestinal parasites throughout the whole stratigraphic sequence: molineids assimilable to Lamanema / Nematodirus genus were present in all samples, whereas Calodium sp. and E. macusaniensis in 78% and 67% of samples, respectively. This parasites community stability contrasts with the few reports of these enteroparasites in current camelids suggesting a low prevalence in the present. Ecological events such as the introduction of cattle and the subsequent invasion of new enteroparasites may probably explain these contrasts between pre-Hispanic and the present times.
