| biologic and molecular characteristics of toxoplasma gondii isolates from striped skunk (mephitis mephitis), canada goose (branta canadensis), black-winged lory (eos cyanogenia), and cats (felis catus). | toxoplasma gondii isolates can be grouped into 3 genetic lineages. type i isolates are considered virulent to outbred mice, whereas type ii and iii isolates are not. in the present report, viable t. gondii was isolated for the first time from striped skunk (mephitis mephitis), canada goose (branta canadensis), and black-winged lory (eos cyanogenia). for the isolation of t. gondii, tissues were bioassayed in mice, and genotyping was based on the sag2 locus. toxoplasma gondii was isolated from 3 o ... | 2004 | 15562622 |
| latitudinal variability in the seroprevalence of antibodies against toxoplasma gondii in non-migrant and arctic migratory geese. | toxoplasma gondii is an intracellular coccidian parasite found worldwide and is known to infect virtually all warm-blooded animals. it requires a cat (family felidae) to complete its full life cycle. despite the absence of wild felids on the arctic archipelago of svalbard, t. gondii has been found in resident predators such as the arctic fox and polar bear. it has therefore been suggested that t. gondii may enter this ecosystem via migratory birds. the objective of this study was to identify loc ... | 2012 | 23339847 |
| genotyping toxoplasma gondii from wildlife in pennsylvania and identification of natural recombinants virulent to mice. | recent studies indicated the predominance of toxoplasma gondii haplogroup 12 in wildlife in the usa. however, still little is known of the genetic diversity of this parasite circulating in wildlife. in the present study, we tested coyotes (canis latrans), red foxes (vulpes vulpes), white-tailed deer (odocoileus virginianus), and geese (branta canadensis) from the state of pennsylvania for t. gondii infection. antibodies to t. gondii were found in 160 of 367 animals, including 92 (34.5%) of 266 c ... | 2014 | 24332401 |
| toxoplasmosis in geese and detection of two new atypical toxoplasma gondii strains from naturally infected canada geese (branta canadensis). | wild birds are important in the epidemiology of toxoplasmosis because they can serve as reservoir hosts, and vectors of zoonotic pathogens including toxoplasma gondii. canada goose (branta canadensis) is the most widespread geese in north america. little is known concerning t. gondii infection in both migratory, and local resident populations of canada geese. here, we evaluated the seroprevalence, isolation, and genetic characterization of viable t. gondii isolates from a migratory population of ... | 2016 | 26796021 |
