Where Are The Parasites? [Letters], Susan J. Kutz, Andy P. Dobson, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

First paragraph:

The review by E. Post et al. ("Ecological dynamics across the Arctic associated with recent climate change," 11 September 2009, p. 1,355) paid little heed to parasites and other pathogens. The rapidly growing literature on parasites in arctic and subarctic ecosystems provides empirical and observational evidence that climate-linked changes have already occurred. The life cycle of the protostrongylid lungworm of muskoxen, Umingmakstrongylus pallikuukensis, has changed, and the range of that organism and the winter tick, Dermacentor albipictus, has expanded.

Genetics And Pathogenesis Of Feline Infectious Peritonitis Virus, Meredith Brown, Jennifer L. Troyer, Jill Pecon-Slattery, M. Roelke-Parker, Stephen J. O'Brien

Feline coronavirus (FCoV) is endemic in feral cat populations and cat colonies, frequently preceding outbreaks of fatal feline infectious peritonitis (FIP). FCoV exhibits 2 biotypes: the pathogenic disease and a benign infection with feline enteric coronavirus (FECV). Uncertainty remains regarding whether genetically distinctive avirulent and virulent forms coexist or whether an avirulent form mutates in vivo, causing FIP. To resolve these alternative hypotheses, we isolated viral sequences from FCoV-infected clinically healthy and sick cats (8 FIP cases and 48 FECV-asymptomatic animals); 735 sequences from 4 gene segments were generated and subjected to phylogenetic analyses. Viral sequences from healthy cats were …

Taxonomic Revision Of Species Of The Genus Monoecocestus (Cestoda: Anoplocephalidae), Terry R. Haverkost

School of Biological Sciences: Dissertations, Theses, and Student Research

My dissertation research is an important contribution to the taxonomy of anoplocephalid cestodes. Almost all research conducted for these chapters was done by staining, mounting, and measuring anoplocephalid cestodes from the Bolivian Biodiversity Survey conducted in Bolivia from 1984-2000. These specimens were collected and processed in the field and deposited in the Harold W. Manter Laboratory of Parasitology. I was particularly interested in species of the genus Monoecocestus Beddard, 1914 that parasitize caviid and sigmodontine rodents. In all instances, the material studied has lead to the description of new species or the redescription of existing species of Monoecocestus. In …
