seroprevalence of toxoplasma gondii in llamas (lama glama) in the northwest usa.serum samples from 283 llamas (lama glama) from oregon, washington state and idaho were tested for antibodies to toxoplasma gondii using the modified agglutination test. antibodies were found in 95 (33.5%) llamas. percent seropositivity in serum dilutions of 1:25, 1:50, 1:500, and 1:5000 was 9.5%, 18.3%, 4.9%, and 0.7%, respectively.19921466137
toxoplasmic encephalitis in a free-ranging rocky mountain bighorn sheep from washington.a 4-mo-old free-ranging rocky mountain bighorn sheep (ovis canadensis canadensis) from the hells canyon area (washington, usa) was diagnosed with encephalitis associated with toxoplasma gondii infection. the sheep had concurrent pneumonic pasteurellosis and resided in a geographic area with endemic pasteurella-associated pneumonia and mortality in bighorn sheep. the brain had multifocal necrotizing and nonsuppurative encephalitis with intralesional protozoa. the protozoa were identified as t. go ...200011085438
dual sarcocystis neurona and toxoplasma gondii infection in a northern sea otter from washington state, usa.dual sarcocystis neurona and toxoplasma gondii infection was observed in a northern sea otter from washington, usa. the animal was found stranded, convulsed, and died shortly thereafter. encephalitis caused by both s. neurona and t. gondii was demonstrated in histological sections of brain. immunohistochemical examination of sections with s. neurona specific antisera demonstrated developmental stages that divided by endopolygeny and produced numerous merozoites. pcr of brain tissue from the sea ...200111390085
seroprevalence of toxoplasma gondii in harbor seals (phoca vitulina) in southern puget sound, washington.as part of the puget sound ambient monitoring program of the washington department of fish and wildlife, serum samples from 380 harbor seals (phoca vitulina) were tested for antibodies to toxoplasma gondii in the modified agglutination test (mat) incorporating formalin-fixed tachyzoites and mercaptoethanol. antibodies to t. gondii were found in 29 of 380 (7.6%) seals with titers of 1:25 in 13, 1:50 in 14, and > or = 1:500 in 2 seals. results indicate natural exposure of these wild marine mammals ...200111695398
evaluation of an indirect fluorescent antibody test (ifat) for demonstration of antibodies to toxoplasma gondii in the sea otter (enhydra lutris).an indirect fluorescent antibody test (ifat) for detection of toxoplasma gondii infection was validated using serum from 77 necropsied southern sea otters (enhydra lutris nereis) whose t. gondii infection status was determined through immunohistochemistry and parasite isolation in cell culture. twenty-eight otters (36%) were positive for t. gondii by immunohistochemistry or parasite isolation or both, whereas 49 (64%) were negative by both tests. at a cutoff of 1:320, combined values for ifat se ...200212099433
prevalence of antibodies to toxoplasma gondii in raccoons (procyon lotor) from an urban area of northern virginia.raccoons (procyon lotor) are intermediate hosts for toxoplasma gondii, and clinical toxoplasmosis in raccoons has been reported. a 2-yr serological survey was conducted to determine the prevalence of antibodies to t. gondii in raccoons collected from fairfax county, virginia, a suburban/urban area outside washington, d.c. serum samples from 256 raccoons were examined for t. gondii antibodies at a 1:50 dilution using the modified direct agglutination test. results indicated that 216 (84.4%) of th ...200516108570
genetic diversity among sea otter isolates of toxoplasma gondii.sea otters (enhydra lutris) have been reported to become infected with toxoplasma gondii and at times succumb to clinical disease. here, we determined genotypes of 39 t. gondii isolates from 37 sea otters in two geographically distant locations (25 from california and 12 from washington). six genotypes were identified using 10 pcr-rflp genetic markers including sag1, sag2, sag3, btub, gra6, c22-8, c29-2, l358, pk1, and apico, and by dna sequencing of loci sag1 and gra6 in 13 isolates. of these 3 ...200818155841
pathogen exposure and blood chemistry in the washington, usa population of northern sea otters (enhydra lutris kenyoni).northern sea otters (enhydra lutris kenyoni) from washington state, united states were evaluated in 2011 to determine health status and pathogen exposure. antibodies to brucella spp. (10%) and influenza a virus (23%) were detected for the first time in this population in 2011. changes in clinical pathology values (serum chemistries), exposure to pathogens, and overall health of the population over the last decade were assessed by comparing 2011 data to the data collected on this population in 20 ...201324502716
