| raccoon roundworms in pet kinkajous--three states, 1999 and 2010. | baylisascaris procyonis (bp) is the common roundworm of raccoons (procyon lotor). adult bp live in the small intestine of this host, where they produce eggs that are passed in the feces. bp eggs ingested by nondefinitive host species hatch in the intestine, producing larvae that can migrate widely, causing visceral, ocular, or neural larva migrans. cases of neural larva migrans in humans caused by bp likely acquired from raccoons have resulted in severe encephalitis with permanent deficits and i ... | 2011 | 21412211 |
| trypanosoma cruzi and chagas' disease in the united states. | chagas' disease is caused by the protozoan parasite trypanosoma cruzi and causes potentially life-threatening disease of the heart and gastrointestinal tract. the southern half of the united states contains enzootic cycles of t. cruzi, involving 11 recognized triatomine vector species. the greatest vector diversity and density occur in the western united states, where woodrats are the most common reservoir; other rodents, raccoons, skunks, and coyotes are also infected with t. cruzi. in the east ... | 2011 | 21976603 |
| baylisascaris procyonis in raccoons (procyon lotor) in eastern tennessee. | raccoon (procyon lotor) carcasses (n=118) were collected from july through december 2007 throughout eastern tennessee. necropsies were performed, and baylisascaris procyonis was collected from the gastrointestinal tract of infected carcasses. prevalence rates were determined for the overall sample population, males and females, and adults and juveniles. the sample population had a b. procyonis prevalence of 12.7%. males and females had a prevalence of 15% and 11%, respectively; prevalence in adu ... | 2009 | 19901404 |

| use of polymerase chain reaction to diagnose the fifth reported us case of autochthonous transmission of trypanosoma cruzi, in tennessee, 1998. | in july 1998, the mother of an 18-month-old boy in rural tennessee found a triatomine bug in his crib, which she saved because it resembled a bug shown on a television program about insects that prey on mammals. the gut contents of the triatoma sanguisuga were found, by light microscopy and polymerase chain reaction (pcr), to be infected with trypanosoma cruzi; pcr products hybridized with t. cruzi-specific oligonucleotide probes. whole-blood specimens obtained from the child in july and august ... | 2000 | 10608796 |
| patterns of infestation by adult dermacentor variabilis (acari: ixodidae) in a mark-recapture study of raccoons (mammalia: carnivora) and virginia opossums (mammalia: didelphimorphia) in tennessee. | a mark-recapture study of raccoons (procyon lotor l.) and virginia opossums (didelphis virginiana kerr) was conducted from february 1991 through april 1994 to determine host interactions with adult dermacentor variabilis say. we captured 1,293 raccoons and virginia opossums during the 3-yr study (140 individual raccoons and 160 individual virginia opossums) with 1,895 adult d. variabilis collected. raccoons had a significantly higher mean intensity and higher prevalence of adult ticks than virgi ... | 1999 | 10337094 |

| geographic variation in helminth parasites from the digestive tract of tennessee raccoons, procyon lotor. | the stomachs and intestinal tracts of 253 raccoons, procyon lotor, were examined for helminth parasites. sixteen species of helminths were found including eight trematodes, two cestodes, five nematodes, and one acanthocephalan. fourteen of these helminths are new geographic records for the state of tennessee. multivariate statistical techniques were used to analyze two-state and multistate character sets. matrices of correlation among characters were computed and the first three principal compon ... | 1980 | 7365628 |
| characterization of a novel canine distemper virus causing disease in wildlife. | canine distemper virus (cdv) is a common cause of a multisystemic disease in both domestic dogs and wildlife species, including raccoons and foxes. outbreaks of cdv in domestic dogs in eastern tennessee have occurred since 2012, and it was determined that these outbreaks resulted from a novel genotype of cdv. we hypothesized that this virus is also infecting area wildlife and may be a source of the virus for these outbreaks in dogs. from 2013 to 2014, autopsies were performed and tissues collect ... | 2016 | 27400957 |
| baylisascaris procyonis in raccoons (procyon lotor) from north carolina and current status of the parasite in the usa. | baylisascaris procyonis is an intestinal nematode of raccoons (procyon lotor) that can cause fatal larva migrans in numerous species of birds and mammals, including humans. historically, this parasite has been rare in the southeastern usa but recently has been reported in eastern tennessee and isolated parts of georgia and florida. the objective of the current study was to investigate the distribution and prevalence of b. procyonis in raccoons from north carolina. in western north carolina, in c ... | 2013 | 23180125 |

| investigation into seasonal scavenging patterns of raccoons on human decomposition. | although raccoons are known as one of the most common scavengers in the u.s., scavenging by these animals has seldom been studied in terms of forensic significance. in this research, the seasonal pattern of raccoon scavenging and its effect on human decomposition was investigated using 178 human cadavers placed at the anthropological research facility (arf) of the university of tennessee, knoxville (utk) between february 2011 and december 2013. the results reveal that (i) the frequency of scaven ... | 2016 | 27404620 |
| metal accumulation and health effects in raccoons (procyon lotor) associated with coal fly ash exposure. | approximately 5.4 million cubic yards of coal fly ash and water spilled into the emory river embayment of watts bar reservoir in east tennessee on dec 22, 2008. raccoons were collected in 2009 and 2010 from the spill site (10/y) and unexposed areas (5/y) to determine whether metals and metalloids were accumulating in raccoons and if any negative health effects resulted from exposure to the spilled coal fly ash. tissues were analyzed from each animal to determine the concentrations of 26 metals/m ... | 2013 | 23292273 |
| genetic relatedness and female spatial organization in a solitary carnivore, the raccoon, procyon lotor. | among mammals, some of the most common types of cohesive social groupings originate from natal philopatry through the extended mother family. this retention of females within social groups (i.e. the nonrandom dispersion of female relatives in space) should affect population genetic structure. we examined the relationship between genetic relatedness and female spatial organization in a wild population of the north-american raccoon, procyon lotor, a solitary carnivore in east tennessee. multilocus ... | 2002 | 12030986 |
