| tularemia, plague, yersiniosis, and tyzzer's disease in wild rodents and lagomorphs in canada: a review. | information related to infection of wild rodents or lagomorphs in canada by francisella tularensis, yersinia pestis, other yersinia spp., and clostridium piliforme was searched for this study. reports on tularemia in humans linked to these species came from diagnostic databases, literature, wildlife health specialists, and public health agencies. tularemia has been diagnosed in 8 species of wild rodent and 2 species in the genus lepus in canada. tularemia occurred in wild animals, or in humans a ... | 2009 | 20190973 |
| spatiotemporal analysis of cryptosporidium species/genotypes and relationships with other zoonotic pathogens in surface water from mixed-use watersheds. | nearly 690 raw surface water samples were collected during a 6-year period from multiple watersheds in the south nation river basin, ontario, canada. cryptosporidium oocysts in water samples were enumerated, sequenced, and genotyped by detailed phylogenetic analysis. the resulting species and genotypes were assigned to broad, known host and human infection risk classes. wildlife/unknown, livestock, avian, and human host classes occurred in 21, 13, 3, and <1% of sampled surface waters, respective ... | 2012 | 23124241 |
| quantitative multi-year elucidation of fecal sources of waterborne pathogen contamination in the south nation river basin using bacteroidales microbial source tracking markers. | over a seven-year period (2004-2010) 1095 water samples were obtained from the south nation river basin at multiple watershed monitoring sites (ontario, canada). real-time pcr using bacteroidales specific markers was used to identify the origin (human (10% prevalence), ruminant (22%), pig (~2%), canada goose (4%) and muskrat (7%)) of fecal pollution. in parallel, the distribution of fecal indicator bacteria and waterborne pathogens (cryptosporidium oocysts, giardia cysts, escherichia coli o157:h ... | 2013 | 23497974 |

| molecular and phylogenetic approaches for assessing sources of cryptosporidium contamination in water. | the high sequence diversity and heterogeneity observed within species or genotypes of cryptosporidium requires phylogenetic approaches for the identification of novel sequences obtained from the environment. a long-term study on cryptosporidium in the agriculturally-intensive south nation river watershed in ontario, canada was undertaken, in which 60 sequence types were detected. of these sequence types 33 were considered novel with no identical matches in genbank. detailed phylogenetic analysis ... | 2012 | 22841595 |
| tracking host sources of cryptosporidium spp. in raw water for improved health risk assessment. | recent molecular evidence suggests that different species and/or genotypes of cryptosporidium display strong host specificity, altering our perceptions regarding the zoonotic potential of this parasite. molecular forensic profiling of the small-subunit rrna gene from oocysts enumerated on microscope slides by u.s. environmental protection agency method 1623 was used to identify the range and prevalence of cryptosporidium species and genotypes in the south nation watershed in ontario, canada. fou ... | 2007 | 17483276 |
| tissue metal levels in muskrat (ondatra zibethica) collected near the sudbury (ontario) ore-smelters; prospects for biomonitoring marsh pollution. | an examination of tissue metal levels in sudbury-area muskrat (ondatra zibethica) revealed that animals collected in the vicinity of the local ore-smelters contained elevated burdens of cd and ni in their liver and kidneys. respective tissue concentrations averaged 2-fold and 3- to 6-fold higher than background values and are believed to reflect accumulations resulting from food chain contamination in regional marshes, including that reportedly characterizing typha latifolia stands-their primary ... | 2004 | 14749066 |
