Protozoan parasites of birds from the Tremembé formation (Oligocene of the Taubaté Basin), São Paulo, Brazil
Objective
To analyze the presence of protozoan parasites in bird coprolites from the Tremembé Formation (Oligocene of the Taubaté Basin).
Materials
Twenty avian coprolites embedded in pyrobituminous shale matrices.
Methods
Samples were rehydrated and subjected to spontaneous sedimentation.
Results
Paleoparasitological analyses revealed oocysts compatible with the Eimeriidae family (Apicomplexa) and one single Archamoebae (Amoebozoa) cyst.
Conclusions
The present work increases the amount of information about the spread of infections throughout the Cenozoic Era and reveals that the Brazilian paleoavifauna played an important role in the Apicomplexa and Amoebozoa life cycles.
Significance
This is the first record of protozoans in avian coprolites from the Oligocene of Brazil. These findings can help in the interpretation of phylogenies of coccidian parasites of modern birds, as certain taxonomic characters observed in the Oligocene Protozoa characterize monophyletic groups in current molecular phylogenetic analyses.
Limitations
None of the oocysts were sporulated; therefore, it is not possible to identify the morphotypes to genus or species.
Suggestions for further research
Our results create new perspectives related to biogeographic studies of the parasitic groups described and may improve the understanding of the temporal amplitude of parasitic evolutionary relationships between Protozoans and birds.
期刊介绍：
Paleopathology is the study and application of methods and techniques for investigating diseases and related conditions from skeletal and soft tissue remains. The International Journal of Paleopathology (IJPP) will publish original and significant articles on human and animal (including hominids) disease, based upon the study of physical remains, including osseous, dental, and preserved soft tissues at a range of methodological levels, from direct observation to molecular, chemical, histological and radiographic analysis. Discussion of ways in which these methods can be applied to the reconstruction of health, disease and life histories in the past is central to the discipline, so the journal would also encourage papers covering interpretive and theoretical issues, and those that place the study of disease at the centre of a bioarchaeological or biocultural approach. Papers dealing with historical evidence relating to disease in the past (rather than history of medicine) will also be published. The journal will also accept significant studies that applied previously developed techniques to new materials, setting the research in the context of current debates on past human and animal health.
