Detection Of Giardia Duodenalis Antigen In Coprolites Using A Commercially Available Enzyme-Linked Immunosorbent Assay, Marcelo Luiz Carvalho Gonçalves, Adauto Araújo, Rosemere Duarte, Joaquim Pereira Da Silva, Karl Reinhard, Françoise Bouchet, Luis Fernando Ferreira Jan 2002

Detection Of Giardia Duodenalis Antigen In Coprolites Using A Commercially Available Enzyme-Linked Immunosorbent Assay, Marcelo Luiz Carvalho Gonçalves, Adauto Araújo, Rosemere Duarte, Joaquim Pereira Da Silva, Karl Reinhard, Françoise Bouchet, Luis Fernando Ferreira

Karl Reinhard Publications

The objective of this experiment was to assess the utility of a commercially available enzyme-linked immunosorbent assay (ELISA) kit for diagnosis of giardiasis in archaeological human remains. The kit, a monoclonal antibody assay, is used to detect the presence of Giardia-specific antigen 65 (GSA65) in human feces. We utilized the assay in ancient fecal material. The material included desiccated feces found in mummies or in archaeological sites, and sediments from latrines. A total of 83 specimens, previously examined microscopically for parasites, were examined. The ELISA detected 3 positive samples, dated to about 1200 AD, 1600 AD, and 1700 AD. …

Multidisciplinary Coprolite Analysis, Karl Reinhard, Dennis R. Danielson, Mark Daniels, Sérgio Augusto De Miranda Chaves Jan 2002

Multidisciplinary Coprolite Analysis, Karl Reinhard, Dennis R. Danielson, Mark Daniels, Sérgio Augusto De Miranda Chaves

Karl Reinhard Publications

Coprolite analysis, as reviewed by Reinhard and Bryant (1992), contributes unique and detailed information regarding diet and parasitic disease. We present here an analysis of dietary components of coprolites from Bighorn Cave using macroscopic remains, pollen concentrations, and phytoliths. In addition, we analyzed Bighorn Cave coprolites for evidence of parasitic organisms, especially intestinal worms. Such analyses of coprolites have become important methods for reconstructing past dietary and medicinal practices. Pollen concentration and phytolith quantification techniques have recently been developed, but until this report no known attempt has been made to synthesize pollen, macroscopic, and phytolith data from a single coprolite …

Ultrastructure Of Tuzetia Weidneri Sp. N. (Microsporidia: Tuzetiidae) In Skeletal Muscle Of Litopenaeus Setiferus And Farfantepenaeus Aztecus (Crustacea: Decapoda) And New Data On Perezia Nelsoni (Microsporidia: Pereziidae) In L. Setiferus, Elizabeth U. Canning, Alan Curry, Robin M. Overstreet Jan 2002

Ultrastructure Of Tuzetia Weidneri Sp. N. (Microsporidia: Tuzetiidae) In Skeletal Muscle Of Litopenaeus Setiferus And Farfantepenaeus Aztecus (Crustacea: Decapoda) And New Data On Perezia Nelsoni (Microsporidia: Pereziidae) In L. Setiferus, Elizabeth U. Canning, Alan Curry, Robin M. Overstreet

A new microsporidian species, Tuzetia weidneri sp. n. , is described from the skeletal muscle of the decapod crustaceans Litopenaeus setiferus and Farfantepenaeus aztecus. Fresh spores are pyriform, measuring 3.1 x 2.3 µm. All stages have unpaired nuclei. Meronts lie in direct contact with degenerate host cell cytoplasm but produce numerous small blisters at the surface. Multinucleate meronts divide by constriction into groups or chains of uninucleate products. Sporogony is initiated by deposition of a dense surface coat on the plasma membrane of uninucleate or multinucleate stages and fusion of blisters to enclose the sporont in a sporophorous vesicle …

Potential Pathological Effects Of Blood Flukes (Digenea: Sanguinicolidae) On Pen-Reared Marine Fishes, Stephen A. Bullard, Robin M. Overstreet Jan 2002

Potential Pathological Effects Of Blood Flukes (Digenea: Sanguinicolidae) On Pen-Reared Marine Fishes, Stephen A. Bullard, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sanguinicolids, or fish blood flukes, infect the vascular system of both marine and freshwater fishes, and some act as serious pathogens of hosts in aquaculture. Blood flukes typically possess a relatively benign relationship with wild fishes; however, cultured hosts near appropriate intermediate hosts (i.e., snail, bivalve, or polychaete) may accumulate heavy infections of the worms and their eggs. The resulting disease, sanguinicoliasis, has caused mass mortalities of fish reared in ponds and cages in North America, Europe, and Asia. In the life cycle, the cercaria emerges from the intermediate invertebrate host and penetrates into and matures in the definitive fish …

Hydrobiid Snails (Mollusca: Gastropoda: Rissooidea) From St. Andrew Bay, Florida, Richard W. Heard, Robin M. Overstreet, John M. Foster Jan 2002

Hydrobiid Snails (Mollusca: Gastropoda: Rissooidea) From St. Andrew Bay, Florida, Richard W. Heard, Robin M. Overstreet, John M. Foster

Heleobops sp. of Hershler and Thompson appears to be the only previously published record for the gastropod family Hydrobiidae Troschel in tidal waters of the St. Andrew Bay System, Florida. Six species occurred in bayous, marshes, and brackish ponds associated with the System during studies conducted between 1984 and 1999: Texadina barretti (Morrison), Texadina sphinctostoma Abbott and Ladd, Littoridinops monroensis (Frauenfeld), Littoridinops palustris Thompson, Onobops jacksoni (Bartsch), and Heleobops sp. A. The last is an apparently undescribed species closely related to Heleobops carrikeri Davis and McKee. Based in part on this study, Heleobops sp. A, which occurs in brackish habitats …
