Hallazgo de Demodex sp. (Trombidiformes: Demodicidae) en coprolitos de Lama guanicoe del sitio arqueológico CCP7 (Santa Cruz, Argentina)

Abstract

El presente trabajo comunica el hallazgo de un ectoparásito en una muestra de coprolitos de guanaco (Lama guanicoe) hallados en el sitio arqueológico Cerro Casa de Piedra 7 (CCP7) ubicado en la provincia de Santa Cruz, Argentina. Se examinaron seis coprolitos del nivel III del sitio arqueológico CCP7 (3990±80 años antes del presente). Los mismos fueron rehidratados, se procesaron por sedimentación espontánea y el sedimento fue observado bajo microscopio óptico. Se registró un ácaro vermiforme identificado como Demodex sp. La detección de Demodex sp. en coprolitos sugiere manifestaciones patológicas del ácaro sobre su hospedador. Este es el primer registro de Demodex para guanacos y también en coprolitos a nivel global.

In the present work, the finding of an ectoparasite in Lama guanicoe coprolites found in Cerro Casa de Piedra, cave 7 archaeological site CCP7 (Santa Cruz Province, Argentina) was reported. Six coprolites collected of level III from CCP7 site (3,990±80 years before present) were rehydrated and submitted to spontaneous sedimentation for microscope analysis. A vermiform mite was identified as Demodex sp., and their presence in coprolites suggests pathological manifestations of the mite on its host. This is the first Demodex record in guanacos and also in coprolites at global level.
