Coprolites attributable to humans, dated from the Pleistocene–Holocene transition, obtained from the archaeological site Cerro Casa de Piedra, Santa Cruz Province, were examined for parasites. The feces were processed by rehydration and spontaneous sedimentation using conventional parasitic procedures. Helminthic eggs recovered were identified as Trichuris sp., Calodium sp., other capilariids, and ancylostomid (Nematoda), probably Hymenolepis sp. and anoplocephalid (Cestoda); one oocyst attributable to Eimeria macusaniensis (Apicomplexa) was also found. According to the life-cycles and specificity of the parasites found, it is possible to suggest that some species (i.e., E. macusaniensis and Calodium sp.) represent parasites in transit or pseudoparasitism. Paleoparasitological results revealed the existence of an intensive relationship between parasites and humans in the Pleistocene–Holocene transition in Patagonia. Evidence suggests an early association among parasites, rock shelters and hunter–gatherers in the region. It is also postulated that the ancient lifestyles associated with caves and rock shelters were conductive to illness. 相似文献

Ascaris lumbricoides (giant roundworm) and Trichuris trichiura (whipworm) are the most common intestinal parasites found in humans worldwide today and they almost always co-occur. However, we find two distinct patterns in archaeological material. In historical North American and Old World contexts, the association of A. lumbricoides and T. trichiura is similar to the modern epidemiological picture. In contrast, the co-occurrence of A. lumbricoides and T. trichiura eggs in prehistoric South America is rare. For prehistoric contexts, T. trichiura is the most common parasite found in archaeological material. Recently molecular biology techniques pointed to a subdiagnosis of roundworm infection in pre-Columbian South American populations. This is contrary to the modern epidemiological picture in which A. lumbricoides infection is predominant. This is a paradox, especially when one considers the number of eggs laid by female daily, 200,000 and 20,000 thousand per day, for A. lumbricoides and T. trichiura respectively. By reviewing the records of these parasites, this paradox is presented and explanations for the paradox are explored. Taphonomy, prehistoric behavior patterns and medicinal plant use seem to be most relevant to the explanation of the paradox. Nematophagous fungi is a less likely factor creating the near absence of A. lumbricoides eggs in the prehistoric New World. 相似文献

Raptor pellets from Cerro Casa de Piedra archaeological sites, Patagonia, have yielded consistent evidence of parasitism and possible zoonoses in ancient times. Pellet samples analyzed were dated at 2740 ± 100 and 3.990 ± 80 years before present and have produced evidence of three intestinal parasite genera. Eggs of two nematodes Trichuris and Calodium, and one cestode, taeniid, were found. Its significance for rock shelters paleoepidemiology of the Holocene is discussed. This study increases the evidences that raptor pellets can be used as source of paleoparasitological information in archaeological sites. 相似文献
