| sarcocystis sp. in mountain goats (oreamnos americanus) in washington: prevalence and search for the definitive host. | during october and november 1986, sarcocystis sp. was detected in 24 of 56 (43%) tongues from hunter-killed mountain goats (oreamnos americanus) in washington (usa). sarcocysts had an unusual sessile polyp-shaped branched wall. mean size of 154 sarcocysts was 71.3 x 37.8 microns (range, 20 to 248 x 10 to 120 microns), and the mean intensity was 2.3 (range, 1 to 28). in an attempt to identify the definitive host, infected tongues were fed to four coyotes (canis latrans), eight domestic dogs, four ... | 1989 | 2509738 |

| ecology and epidemiology of raccoon rabies. | two areas of the united states presently are experiencing epizootics of raccoon rabies, which have been followed by the development of an enzootic state. these include four southeastern and five mid-atlantic states. information was obtained from 1,610 raccoons submitted for rabies testing in four of the affected mid-atlantic states during 1982 and 1983 and from 798 raccoons from virginia during 1984 and 1985. analysis of the two sets of data provided an opportunity to characterize certain aspect ... | 1988 | 3264616 |
| prevalence of agglutinating antibodies to sarcocystis neurona in raccoons (procyon lotor) from an urban area of virginia. | equine protozoal myeloencephalitis is the most important protozoan disease of horses in north america and is usually caused by sarcocystis neurona. natural and experimentally induced cases of encephalitis caused by s. neurona have been reported in raccoons (procyon lotor) and raccoons are an intermediate host for this parasite. a 3-yr-long serological survey was conducted to determine the prevalence of agglutinating antibodies to s. neurona in raccoons collected from fairfax county, virginia, a ... | 2004 | 15357091 |
| prevalence of antibodies to trypanosoma cruzi in raccoons (procyon lotor) from an urban area of northern virginia. | raccoons (procyon lotor) are reservoir hosts for trypanosoma cruzi. a 3-yr-long serological survey was conducted to determine the prevalence of antibodies to this zoonotic parasite in raccoons collected from fairfax county, virginia, a suburban/urban area outside washington, d.c. serum samples from 464 raccoons were examined for t. cruzi antibodies at a 1:40 dilution with an indirect fluorescent antibody test (ifat) and brazil strain t. cruzi amastigotes and trypomastigotes as antigen. a positiv ... | 2005 | 15986630 |
| 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 ... | 2005 | 16108570 |
| first records of rodent-infesting cuterebra bot flies parasitizing raccoons (procyon lotor) in north america. | larvae of cuterebra spp. bot flies are specialized parasites of native species of either rodentia (e.g., mice, rats, and tree squirrels) or lagomorpha (e.g., rabbits and hares) in the americas. however, they also infest other native and introduced wildlife, domestic animals, and humans, but which cuterebra species parasitize these "atypical" hosts has seldom been determined, largely because the larvae are difficult to identify to species without first rearing them to adults. here, we describe 2 ... | 2006 | 17304824 |
| modest genetic differentiation among north american populations of sarcocystis neurona may reflect expansion in its geographic range. | sarcocystis neurona is an important cause of neurological disease in horses (equine protozoal myeloencephalitis, epm) and sea otters in the united states. in addition, epm-like disease has been diagnosed in several other land and marine mammals. opossums are its only definitive hosts. little genetic diversity among isolates of s. neurona from different hosts has been reported. here, we used 11 microsatellites to characterize s. neurona dna isolated from natural infections in 22 sea otters (enhyd ... | 2008 | 18243561 |
| serological survey for antibodies to leptospira in dogs and raccoons in washington state. | a high number of reported canine leptospirosis cases occurred in washington state from 2004 to 2006. this prompted a serosurvey of healthy dogs from around the state to determine the distribution of exposure risk and to provide insight into serovar epidemiology in the region. in addition, a convenience sample of sera from injured raccoons was also tested, and clinical serological data from the washington animal disease diagnostic laboratory were examined. the proportion of dogs with an antibody ... | 2008 | 18631236 |
| acceptance of simulated oral rabies vaccine baits by urban raccoons. | in summer 1986, a study was conducted to evaluate raccoon (procyon lotor) acceptance of oral baits that could be used for rabies vaccination. one thousand wax-coated sponge bait cubes were filled with 5 mg of a seromarker (iophenoxic acid), placed in polyethylene bags, and hand-distributed in an 80 ha area within an urban national park in washington, d. c. (usa). after 3 wk, target and nontarget animals were trapped and blood samples collected to evaluate bait uptake. thirty-three of 52 (63%) ra ... | 1989 | 2915389 |
