| serologic evidence of avian influenza (h4n6) exposure in a wild-caught raccoon. | growing concerns about avian influenza, and its effect on agriculture and human health, have highlighted the need to understand the role of wildlife in maintaining and spreading the virus. we surveyed the wildlife inhabiting a poultry farm with recent h3n6 and h4n6 avian influenza virus exposure in pennsylvania, u.s.a. one raccoon (procyon lotor) tested positive for h4n6 antibodies. this is the first recorded incident of avian influenza exposure in a wild raccoon. we suggest that raccoons may pl ... | 2009 | 19848088 |
| further development of raccoon poxvirus-vectored vaccines against plague (yersinia pestis). | in previous studies, we demonstrated protection against plague in mice and prairie dogs using a raccoon pox (rcn) virus-vectored vaccine that expressed the f1 capsular antigen of yersinia pestis. in order to improve vaccine efficacy, we have now constructed additional rcn-plague vaccines containing two different forms of the lcrv (v) gene, including full-length (vfull) and a truncated form (v307). mouse challenge studies with y. pestis strain co92 showed that vaccination with a combination of rc ... | 2009 | 19879228 |
| prevalence and distribution of baylisascaris procyonis in urban raccoons (procyon lotor) in winnipeg, manitoba. | the prevalence of baylisascaris procyonis was estimated in the urban raccoon population of winnipeg through the fecal flotation of raccoon feces collected at active latrines and through gross postmortem and fecal flotation of samples collected from nuisance raccoons. fecal flotation of latrine-collected feces was positive in 33 of 89 samples and, of 52 latrines identified, 26 were positive on 1 or more occasions. trapped individual raccoons subjected to postmortem examination were positive in 57 ... | 2009 | 19881923 |
| human vaccinia infection after contact with a raccoon rabies vaccine bait - pennsylvania, 2009. | since 2003, the u.s. department of agriculture's wildlife services has coordinated a multistate oral rabies vaccination (orv) program for wildlife in a 15-state zone extending from maine to alabama and in texas. the program seeks to enhance local control and prevent the spread of epizootic rabies among raccoons and, in texas, among gray foxes and coyotes. the program uses baits containing liquid vaccinia-rabies glycoprotein (v-rg) recombinant virus vaccine. because contact with ruptured baits ca ... | 2009 | 19893480 |
| rabies in northeastern europe--the threat from invasive raccoon dogs. | the red fox (vulpes vulpes) is the main terrestrial wildlife rabies vector in europe. however, recently the raccoon dog (nyctereutes procyonoides)--an invasive species originating from east asia--has become increasingly important as secondary host, especially in the baltic states. this imposes problems on neighboring rabies-free countries (such as finland), where the density of each of the two vector species on its own might be too low to sustain a long-term rabies epizootic, but the community o ... | 2009 | 19901385 |
| antibodies to west nile virus in raccoons and other wild peridomestic mammals in iowa. | surveillance for evidence of west nile virus (wnv) infection in small- and medium-sized wild mammals was conducted in iowa, usa, from may 2005 to june 2007. sera were collected from 325 mammals belonging to nine species and tested for antibodies to wnv and other flaviviruses by epitope-blocking enzyme-linked immunosorbent assay (elisa). all sera that had antibodies to flaviviruses by blocking elisa were further examined by plaque reduction neutralization test (prnt). thirteen mammals were seropo ... | 2009 | 19901390 |

| bacteroidales diversity in ring-billed gulls (laurus delawarensis) residing at lake michigan beaches. | this study investigated the occurrence and diversity of bacteroidales fecal bacteria in gulls residing in the great lakes region. members of this bacterial order have been widely employed as human and bovine host-specific markers of fecal pollution; however, few studies have focused on gulls, which can be a major source of fecal indicator bacteria and pathogens at beaches. we found a low but consistent occurrence of bacteroidales in gulls at five beaches in three different counties spanning the ... | 2009 | 19151182 |
| gastrointestinal helminths in raccoons in texas. | raccoons (n=590) were collected from october 1999 to august 2003 from 35 counties across texas, and gastrointestinal tracts were examined for helminth parasites. prevalence was calculated and differences in mean abundance were examined among habitat ecoregions, age classes, and between sexes. twenty different species of helminths (13 nematodes, two cestodes, two acanthocephalans, and three trematodes) were positively identified in the gastrointestinal tracts of 590 raccoons in texas. five of the ... | 2009 | 19204330 |
| prevalence of baylisascaris procyonis in raccoons (procyon lotor) in portland, oregon, usa. | we investigated the prevalence of baylisascaris procyonis in raccoons living in the metropolitan area of portland, oregon, usa, in order to assess the potential public health risk involved in the transmission of b. procyonis to humans and companion animals. sixty-nine euthanized raccoons were collected from portland wildlife-control agencies. infection with b. procyonis was determined through the harvesting of adult worms from raccoon intestines during necropsy and by fecal analysis using modifi ... | 2009 | 19204331 |
| unusual odd-chain and trans-octadecenoic fatty acids in tissues of feral european beaver (castorfiber), eurasian badger (melesmeles) and raccoon dog (nyctereutesprocyonoides). | the fatty acid (fa) composition of depot adipose tissues in the raccoon dog (nyctereutesprocyonoides) and the european beaver (castorfiber) differs from that reported for the lipids of other monogastric animals, especially with regard to the presence of trans-octadecenoic acids. the concentrations of pentadecanoic acid 15:0 (pa) and heptadecanoic acid 17:0 (ha) in the lipids of the tested animals ranged from 0.23 to 0.79% and from 0.33 to 2.35% of total fas, respectively. the total content of th ... | 2009 | 19243702 |
| molecular characterization of highly pathogenic h5n1 avian influenza a viruses isolated from raccoon dogs in china. | the highly pathogenic avian influenza h5n1 virus can infect a variety of animals and continually poses a threat to animal and human health. while many genotypes of h5n1 virus can be found in chicken, few are associated with the infection of mammals. characterization of the genotypes of viral strains in animal populations is important to understand the distribution of different viral strains in various hosts. this also facilitates the surveillance and detection of possible emergence of highly pat ... | 2009 | 19270752 |
| landscape modelling spatial bottlenecks: implications for raccoon rabies disease spread. | a landscape genetic simulation modelling approach is used to understand factors affecting raccoon rabies disease spread in southern ontario, canada. using the ontario rabies model, we test the hypothesis that landscape configuration (shape of available habitat) affects dispersal, as indicated by genetic structuring. we simulated range expansions of raccoons from new york into vacant landscapes in ontario, in two areas that differed by the presence or absence of a landscape constriction. our resu ... | 2009 | 19324623 |
| molecular evidence for the presence of new babesia species in feral raccoons (procyon lotor) in hokkaido, japan. | we recently reported that feral raccoons (procyon lotor) with splenomegaly native to japan were carriers of a babesia microti-like parasite identical to that found in the united states, which was likely introduced to japan from north america via raccoons imported as pets. thus, we attempted extensive molecular survey for piroplasma infections of feral raccoon with normal spleen in hokkaido, japan using nested pcr that target broadly to 18s ribosomal rna gene (ssu-rdna) of all the parasites in th ... | 2009 | 19349121 |
| a suspected canine distemper epidemic as the cause of a catastrophic decline in santa catalina island foxes (urocyon littoralis catalinae). | the island fox (urocyon littoralis catalinae) population on santa catalina island, california, usa declined precipitously in 1999 with an approximate 95% reduction on their eastern range, an area representing 87% of the island. during this investigation, between october 1999 and april 2000, evidence of live foxes dramatically decreased. the only carcass recovered during the decline succumbed to a co-infection of canine distemper virus (cdv) and toxoplasmosis. sequence analysis of the viral p gen ... | 2009 | 19395743 |

| animal rabies in massachusetts, 1985-2006. | in this study, we review annual rabies data from massachusetts from 1985 to 2006, spanning the introduction of raccoon strain rabies in 1992. of 52,034 animals tested, 9.7% (5,049/52,034) were rabid, representing 26 of over 67 species submitted. bats were the most common rabid animals prior to 1992 (50 of 52), but raccoons (procyon lotor) became the most common rabies-positive species upon arrival of raccoon strain rabies virus (38.2%, 2,728 of 7,138 tested), followed by striped skunks (mephitis ... | 2009 | 19395747 |
| nightly and seasonal movements, seasonal home range, and focal location photo-monitoring of urban striped skunks (mephitis mephitis): implications for rabies transmission. | we followed radio-collared striped skunks (mephitis mephitis) from january 2004-december 2005 in two urban areas of flagstaff, arizona, usa to determine seasonal patterns of movement and home-range size. we also used automated cameras to determine the potential for inter- and intraspecific interaction at skunks' diurnal resting sites and nocturnal focal locations. we found no difference between sexes in nightly rates of travel or in size of seasonal home range. nightly rates of travel were great ... | 2009 | 19395748 |
| serologic survey for selected infectious diseases in raccoons (procyon lotor) in indiana, usa. | the objective of this study was to characterize the antibody prevalence of important livestock and domestic animal pathogens in raccoons (procyon lotor) trapped and sampled in 39 forest patches in north-central indiana, usa, between 2004 and 2005. a total of 459 serum samples were tested for antibodies to leptospira serovars, 512 for canine distemper virus (cdv) antibodies, and 340 for antibodies to porcine reproductive and respiratory syndrome virus (prrsv). in total, 47, 16, and 0% of the samp ... | 2009 | 19395767 |
| isolation and characterization of leptospira spp. from raccoons in japan. | we investigated whether raccoons (procyon lotor) carried leptospires in their kidneys in japan. leptospira was isolated from 2 of 71 raccoons captured in kanagawa prefecture and 1 of 53 raccoons at a zoological park in nagasaki prefecture. anti-leptospira antibodies were detected in 16 of 124 raccoons (12.9%) in kanagawa and 33 of 53 raccoons (62.3%) in nagasaki, respectively. the partial nucleotide sequences of their flab genes suggested that the isolates belonged to l. interrogans. the serovar ... | 2009 | 19420844 |
| wild ecotopes and food habits of triatoma longipennis infected by trypanosoma cruzi lineages i and ii in mexico. | the control of wild triatomine populations that can invade dwellings is a major challenge for chagas disease control in mexico, but a better knowledge of the biology of these populations is required to develop appropriate control methods. we describe a new terrestrial ecotope of triatoma longipennis, a principal vector in the occidental part of mexico, in addition to its previously identified niche in rock pile boundary walls. analysis of feeding hosts in the two ecotopes showed that this specie ... | 2009 | 19478263 |
| the relationship between baylisascaris procyonis prevalence and raccoon population structure. | parasite transmission is a dynamic process that can be affected by factors including host and parasite population dynamics. raccoons ( procyon lotor ) are the definitive host of baylisascaris procyonis , an intestinal roundworm. transmission of this parasite has been linked to raccoon behavior and human land-use patterns; however, we do not know the importance of host population structure. therefore, the objective of this study was to determine the relationship between raccoon population attribu ... | 2009 | 19480537 |
| feline panleukopenia. abcd guidelines on prevention and management. | overview: feline panleukopenia virus (fpv) infects all felids as well as raccoons, mink and foxes. this pathogen may survive in the environment for several months and is highly resistant to some disinfectants. infection: transmission occurs via the faecal-oral route. indirect contact is the most common route of infection, and fpv may be carried by fomites (shoes, clothing), which means indoor cats are also at risk. intrauterine virus transmission and infection of neonates can occur. disease sign ... | 2009 | 19481033 |
| evaluation of the chagas stat-pak assay for detection of trypanosoma cruzi antibodies in wildlife reservoirs. | an immunochromatographic assay (chagas stat-pak) was evaluated for the detection of trypanosoma cruzi antibodies in 4 species of wildlife reservoirs. antibodies to t. cruzi were detected in raccoons (procyon lotor) (naturally and experimentally infected) and degus (octodon degu) (experimentally-infected) using the chagas stat-pak. in naturally exposed wild raccoons, the chagas stat-pak had a sensitivity and specificity of 66.7-80.0% and 96.3%, respectively. compared with indirect immunofluoresce ... | 2009 | 19016578 |
| hydroxylated polychlorinated biphenyls (oh-pcbs) in the blood of mammals and birds from japan: lower chlorinated oh-pcbs and profiles. | an analytical method was developed to measure tri- to octa-chlorinated oh-pcbs and pentachlorophenol (pcp) in the whole blood. further, baseline data on the levels and profiles of these phenolic compounds in japanese mammals (human, cat, dog, raccoon dog, and northern fur seal) and birds (black-tailed gull, common cormorant, and jungle crow) were obtained. eighteen identifiable and fifty unknown peaks of oh-pcbs were detected and the major congeners identified were 4'oh-cb101/120, 4oh-cb107/4'oh ... | 2009 | 19054541 |
| synanthropic trichinella infection in finland. | the first three human trichinellosis cases in finland were recorded around 1890, and altogether eight cases were registered until 2008. the first infected finnish swine was found in 1954. from the early 1980s, an increasing trend in the number of infected swine was seen, with the highest number registered in 1996, after which a decrease has been observed. infected pigs were found yearly until 2004. since 1954, all slaughtered pigs have been tested for trichinella, regardless of subsequent export ... | 2009 | 19054618 |
| landscape genetics of raccoons (procyon lotor) associated with ridges and valleys of pennsylvania: implications for oral rabies vaccination programs. | raccoons are the reservoir for the raccoon rabies virus variant in the united states. to combat this threat, oral rabies vaccination (orv) programs are conducted in many eastern states. to aid in these efforts, the genetic structure of raccoons (procyon lotor) was assessed in southwestern pennsylvania to determine if select geographic features (i.e., ridges and valleys) serve as corridors or hindrances to raccoon gene flow (e.g., movement) and, therefore, rabies virus trafficking in this physiog ... | 2009 | 19125658 |
| cardiovascular anatomy, physiology, and disease of rodents and small exotic mammals. | cardiovascular disease in small exotic mammals is anecdotally common, but clinical reports of diagnosis and treatment of disease are rare. this article focuses on known causes of cardiovascular disease in the small exotic mammal. normal anatomy and physiology, as it differs from the dog and cat, is also highlighted. cardiomyopathy, dirofilariasis, atrial thrombosis, and other acquired and congenital cardiac and vascular diseases of rodents, hedgehogs, sugar gliders, raccoons, opossums, and skunk ... | 2009 | 19131033 |
| differential permeability of rivers to raccoon gene flow corresponds to rabies incidence in ontario, canada. | the correlation of landscape features with genetic discontinuities reveals barriers to dispersal that can contribute to understanding present and future spread of wildlife diseases. this knowledge can then be used for targeting control efforts. the impact of natural barriers on raccoon dispersal was assessed through genetic analysis of samples from two regions, niagara (n = 666) and st. lawrence (n = 802). these areas are transected by major rivers and are at the northern front of a raccoon rabi ... | 2009 | 19140963 |
| relative importance of demographics, locale, and seasonality underlying louse and flea parasitism of raccoons (procyon lotor). | a variety of demographic, seasonal, and site-specific variables may influence parasitism, but the relative importance of these variables is generally unclear. we measured the relative ability of host characteristics, season, and site to explain louse (trichodectes octomaculatus) and flea (orchopeas howardi) infestation across 10 populations of raccoons (procyon lotor). lice are highly dependent on specific hosts and are predicted to display a relatively strong relationship with factors intrinsic ... | 2009 | 18578574 |
| transmammary infection of free-ranging florida panther neonates by alaria marcianae (trematoda: diplostomatidae). | two freshly-dead female florida panther (fp) neonates, puma concolor couguar (=puma concolor coryi), an 11-day-old and a 17-day-old, were collected in the florida panther national wildlife refuge (26 degrees 14'n, 81 degrees 36'w), collier county, florida. the 2 neonates were siblings and had presumably fed only on milk from the dam since birth. a 12-day-old female fp neonate was collected in the big cypress national preserve (26 degrees 05'n, 81 degrees 15'w), collier county, florida and had al ... | 2009 | 18665664 |
| oral transmission of trypanosoma cruzi with opposing evidence for the theory of carnivory. | we present the first demonstration of oral transmission of trypanosoma cruzi to raccoons (procyon lotor), a natural reservoir host in the united states, by ingestion of trypomastigotes and infected bugs, but not infected tissue. to investigate an alternative, non-vector-based transmission method, we tested the hypothesis that raccoons scavenging on infected hosts results in patent infection. macerated tissue from selected organs infected with amastigote stages of t. cruzi was orally administered ... | 2009 | 18763853 |
| risk-based cost modelling of oral rabies vaccine interventions for raccoon rabies. | distribution of oral rabies vaccine (orv) is an effective but costly strategy to control raccoon rabies. because of high costs, orv for raccoon rabies in the u.s. has been limited primarily to epizootic areas, leaving extensive raccoon rabies regions without any orv intervention. several cost scenarios for orv application in raccoon rabies enzootic and epizootic regions were modelled in new york state to obtain estimated costs of orv baits per scenario and potential savings compared with a unifo ... | 2009 | 18771519 |
| [non-indigenous and non-specific parasitic nematodes--the background and the consequences]. | introduction of the host is the main reason behind introduction of the parasite, e. g., nematodes. the introduction of the japanese eel (anguilla japonica) in europe in the 1980s resulted in expansion of the swimbladder nematode anguillicola crassus which soon invaded not only populations of the european eel (a. anguilla), but also other local fish. the raccoon (procyon lotor) is native to north america. it is the specific host of strongyloides procyonis and baylisascaris procyonis. more than 90 ... | 2009 | 20209803 |
| [baylisascariasis--a new dangerous zoonosis]. | baylisascaris procyonis is a large nematode of the order ascaridida, specific for raccoon (procyon lotor). in north america, raccoons are extremely common in rural, suburban, and urban settings, where they have become well adapted to living alongside people. in the 1930s raccoons were introduced into europe (i. a. poland) and asia for the commercial fur trade and into japan as pets. the prevalence of b. procyonis infection in raccoons is often high, and infected animals can disseminate in their ... | 2009 | 20209804 |
| the important zoonoses in the protected areas of the tatra national park (tanap). | the northern part of slovakia constitutes an important tourist and recreational area of the country. protected localities of the tatra national park (tanap) are characterised by specific ecological conditions. the high numbers of animals inhabiting protected areas of the tanap and their potential encounters with tourists contribute to a risk of transmission of important parasitic zoonoses. the aim of presently reported study was to perform a long-lasting and detailed survey on the occurrence of ... | 2009 | 20209814 |
| a child with raccoon roundworm meningoencephalitis: a pathogen emerging in your own backyard? | raccoon roundworm (baylisascaris procyonis) is a cause of devastating neural and ocular disease. the first documented case of raccoon roundworm encephalitis in canada, in a seven-year-old boy who presented with severe neurological impairment, is presented. his significant recovery illustrates the importance of clinical suspicion and the benefit of early treatment. | 2009 | 21119798 |
