Pathoecology studies the factors that contribute to the maintenance of infections in past populations and their possible health consequences. Aiming to apply the concept of pathoecology in an archaeological site in the Northeast region of Brazil, six samples of coprolites of animal origin from the Pedra do Tubarão Archaeological Site, dated between...
Chapter
Ancient parasite studies depend on the recovery of parasite remains from archaeological material. Collection strategies, sample processing, and the use of parasitological techniques are essential to perform the analyses without loss of microremains and also to interpret the data obtained by correlating with the archaeological information. Together...

Pinworms infected Ancestral Pueblo populations since early periods of occupation on the Colorado Plateau. The high prevalence of pinworm found in these populations was correlated with the habitation style developments through time. However, in previous studies, Turkey Pen Cave, an early occupation site, and Salmon Ruins, a late occupation site, exh...

Pretos Novos cemetery (PNC), Rio de Janeiro, Brazil (1769-1830) was created exclusively to bury enslaved Africans who died upon arrival at the city or before being sold in the slave market. The PNC site may be unique in the Americas in allowing the study of African parasite infections acquired in Africa. We aimed to identify parasites infecting PNC...

The study of coprolites has been a theme of archaeology in the American Southwest. A feature of archaeoparasitology on the Colorado Plateau is the ubiquity of pinworm infection. As a crowd parasite, this ubiquity signals varying concentrations of populations. Our recent analysis of coprolite deposits from 2 sites revealed the highest prevalence of...

There is often the risk of confusing pollen grains with helminth eggs from archaeological sites. Thousands to millions of pollen grains can be recovered from archaeological burial sediments that represent past ritual, medication and environment. Some pollen grain types can be similar to parasite eggs. Such a confusion is represented by the diagnosi...

The impact of coprolite taphonomy on parasite remains and aDNA recovery has been recognized. In general, coprolites from sites protected by geologic features such as caves and rock shelters exhibit the best preservation. In contrast, coprolites from open sites can be badly affected by taphonomic processes as shown by analyses of parasite eggs. For...
Article
Pathoecology studies the environmental and cultural factors that contribute to the maintenance of infections or diseases in populations. Concerning parasites, it requires the evaluation of these factors based on the presence and life cycle of these organisms. For this reason, it is possible to apply this concept in the context of ancient population...

Article
For archaeological studies it is always necessary to consider taphonomic factors that could have influenced in ancient material preservation. Parasite eggs are usually highly degraded in ancient sites dated from all periods of time and taphonomic factors are mentioned to explain absence and low quantity of eggs found. In this study, we compare para...

In the field of archaeological parasitology, researchers have long documented the distribution of parasites in archaeological time and space through the analysis of coprolites and human remains. This area of research defined the origin and migration of parasites through presence/absence studies. By the end of the 20th century, the field of pathoeco...

This is the handout for microscopic observation of ancient parasite eggs in WORKSHOP II "Parasitology in Paleopathology: New perspectives using large data bases" (organized by Dong H. SHIN, Morgana CAMACHO, Johnica MORROW, Karl REINHARD), 45th Annual North American Meeting of Paleopathology Association, Austin (Texas), 9-11 April, 2018
Article
For more than 30 years, paleoparasitologists attempted to recover parasite remains from burial sediments and archaeological layers in Brazilian shellmounds. These sites are located along the shoreline of the country especially at the South and Southeastern regions, and for that reason they are exposed to frequent rainfall. Most of the shellmounds w...

Parasite findings in sambaquis (shell mounds) are scarce. Although the 121 shell mound samples were previously analysed in our laboratory, we only recently obtained the first positive results. In the sambaqui of Guapi, Rio de Janeiro, Brazil, paleoparasitological analysis was performed on sediment samples collected from various archaeological layer...

Project
Avaliação da frequência de infecções e identificação das espécies parasitárias circulantes na comunidade civil e militar da Ilha da Marambaia, Mangaratiba, Rio de Janeiro, Brasil; com realização de atividades de educação em saúde, visando à prevenção destas das enteroparasitoses.
Project
Objetiva-se neste projeto o diagnostico de infecção por protozoários do gênero Leishmania, através do encontro de fragmentos de DNA parasitário nos vestígios arqueológicos, assim como de anticorpos anti-Leishmania e também antígenos do parasito. A aplicação de mais de uma técnica ratifica os resultados encontrados e a padronização dos testes imunológicos servirão como mais opções de metodologia para o diagnóstico parasitário na linha de estudos da paleoparasitologia. Ademais, os resultados obtidos trarão elucidações quanto à evolução e filogenia das respectivas espécies analisadas, assim como às relações parasito-hospedeiro no passado e na atualidade
Project
Estudar a ocorrência de Leishmania tarentolae no Município de Itacambira, Minas Gerais, Brasil na atualidade, correlacionando com o achado dessa espécie no passado.
