the mirna world of polyomaviruses.polyomaviruses are a family of non-enveloped dna viruses infecting several species, including humans, primates, birds, rodents, bats, horse, cattle, raccoon and sea lion. they typically cause asymptomatic infection and establish latency but can be reactivated under certain conditions causing severe diseases. micrornas (mirnas) are small non-coding rnas that play important roles in several cellular processes by binding to and inhibiting the translation of specific mrna transcripts. in this review ...201323984639
evaluation of the zoonotic potential of transmissible mink encephalopathy.successful transmission of transmissible mink encephalopathy (tme) to cattle supports the bovine hypothesis for the still controversial origin of tme outbreaks. human and primate susceptibility to classical bovine spongiform encephalopathy (c-bse) and the transmissibility of l-type bse to macaques indicate a low cattle-to-primate species barrier. we therefore evaluated the zoonotic potential of cattle-adapted tme. in less than two years, this strain induced in cynomolgus macaques a neurological ...201325437205
trypanosoma cruzi infection in neotropical wild carnivores (mammalia: carnivora): at the top of the t. cruzi transmission chain.little is known on the role played by neotropical wild carnivores in the trypanosoma cruzi transmission cycles. we investigated t. cruzi infection in wild carnivores from three sites in brazil through parasitological and serological tests. the seven carnivore species examined were infected by t. cruzi, but high parasitemias detectable by hemoculture were found only in two procyonidae species. genotyping by mini-exon gene, pcr-rflp (1f8/akw21i) and kdna genomic targets revealed that the raccoon ( ...201323861767
impacts of tree rows on grassland birds and potential nest predators: a removal experiment.globally, grasslands and the wildlife that inhabit them are widely imperiled. encroachment by shrubs and trees has widely impacted grasslands in the past 150 years. in north america, most grassland birds avoid nesting near woody vegetation. because woody vegetation fragments grasslands and potential nest predator diversity and abundance is often greater along wooded edge and grassland transitions, we measured the impacts of removing rows of trees and shrubs that intersected grasslands on potenti ...201323565144
genetic variation and exchange in trypanosoma cruzi isolates from the united states.trypanosoma cruzi, the causative agent of chagas disease, is a multiclonal parasite with high levels of genetic diversity and broad host and geographic ranges. molecular characterization of south american isolates of t. cruzi has demonstrated homologous recombination and nuclear hybridization, as well as the presence of 6 main genetic clusters or "discrete typing units" (dtus). few studies have extensively investigated such exchange events and genetic diversity in north american isolates. in the ...201323457528
southern plains woodrats (neotoma micropus) from southern texas are important reservoirs of two genotypes of trypanosoma cruzi and host of a putative novel trypanosoma species.trypanosoma cruzi, the causative agent of chagas' disease, is an important public health and veterinary pathogen. although human cases are rare in the united states, infections in wildlife, and in some areas domestic dogs, are common. in 2008 and 2010, we investigated t. cruzi prevalence in possible vertebrate reservoirs in southern texas, with an emphasis on southern plains woodrats (neotoma micropus). infection status was determined using a combination of culture isolation, polymerase chain re ...201323127189
ultrastructural characterization of male and female physaloptera rara (spirurida: physalopteridae): feline stomach worms.physaloptera rara (spirurida: physalopteridae) has been found in dogs, coyotes, raccoons, wolves, foxes, cats, and bobcats in north america. the parasites' developmental cycles involve insects, including beetles, cockroaches, and crickets, as intermediate hosts. the nematodes firmly attach to the wall of the stomach and duodenum, where they feed on the mucosa and suck blood. frequent movement of these nematodes results in erosions and ulcers in the gastrointestinal tract. the present study repor ...201323455940
molecular detection of spotted fever group rickettsia in feral raccoons (procyon lotor) in the western part of japan.rickettsial infection in feral raccoons (procyon lotor) in the western part of japan (shimane, fukuoka, saga and nagasaki prefectures) was surveyed by a nested polymerase chain reaction (pcr) assay detecting the rickettsial citrate synthase (glta) gene. four of one hundred and ninety-four feral raccoon spleens (2.1%) were positive for rickettsia spp. one glta gene sequence was identical to r. helvetica, whereas the other 3 sequences were identical and had the highest similarity (98.4%) to r. amb ...201322986299
wildlife contact rates at artificial feeding sites in texas.given the popularity of feeding white-tailed deer (odocoileus virginianus) in texas and the increasing amount of corn that is distributed, more information is needed on the impacts of this activity on non-target wildlife. our objectives were to report visitation, intra- and interspecific contact, and contact rates of wildlife at artificial feeding sites in texas. our study was conducted at three sites in kleberg and nueces counties, texas. we trapped animals from february to april and august to ...201323609307
tracing the sars-coronavirus.four coronaviruses (hcov-229e, hcov-oc43, hcov-nl63, hcov-hku1) are endemic in humans and mainly associated with mild respiratory illnesses; whereas the other two coronaviruses [severe acute respiratory syndrome coronavirus (sars-cov) and middle east respiratory syndrome coronavirus (mers-cov)] present as emerging infections causing severe respiratory syndrome. coronaviruses evolve by accumulation of point mutations and recombination of genomes among different strains or species. mammalian coron ...201323977431
comparison of techniques of detecting immunoglobulin-binding protein reactivity to immunoglobulin produced by different avian and mammalian species.the rationale of this study was to use several immunological assays to investigate the reactivity of immunoglobulin binding protein (ibp) to immunoglobulins from various avian and mammalian species. the ibp studied were staphylococcal protein a (spa), streptococcal protein g (spg), peptostreptococcal protein l (spl) and recombinant protein la (spla). the various immunological techniques used were double immunodiffusion (ouchterlony technique) that tested positive high protein reactivities, direc ...201324171322
baylisascariosis--infections of animals and humans with 'unusual' roundworms.the nematode genus baylisascaris (order ascaridida, superfamily ascaridoidea) contains nine relatively host-specific, parasite species of carnivores, omnivores, herbivores, carnivorous marsupials or rodents. they have a facultative heteroxenous life cycle, at least under experimental conditions. eggs passed in faeces embryonate in the environment and the second-stage larva infective for both definitive and intermediate hosts develops. in intermediate hosts larvae migrate extensively through tiss ...201323339846
search: spatially explicit animal response to composition of habitat.complex decisions dramatically affect animal dispersal and space use. dispersing individuals respond to a combination of fine-scale environmental stimuli and internal attributes. individual-based modeling offers a valuable approach for the investigation of such interactions because it combines the heterogeneity of animal behaviors with spatial detail. most individual-based models (ibms), however, vastly oversimplify animal behavior and such behavioral minimalism diminishes the value of these mod ...201323717647

a spatial mark--resight model augmented with telemetry data.abundance and population density are fundamental pieces of information for population ecology and species conservation, but they are difficult to estimate for rare and elusive species. mark--resight models are popular for estimating population abundance because they are less invasive and expensive than traditional mark-recapture. however, density estimation using mark-resight is difficult because the area sampled must be explicitly defined, historically using ad hoc approaches. we developed a sp ...201323687880
carbon export from the raccoon river, iowa: patterns, processes, and opportunities.farmed landscapes are engineered for productivity, and research suggests they contribute a disproportionate share of inorganic c to the mississippi river and gulf of mexico. here we use alkalinity and total organic c (toc) measurements collected from the raccoon river of iowa to (i) evaluate inorganic and organic c concentrations and export patterns, (ii) compare current trends to historical conditions, and (iii) link c transport processes to current land use management. export of inorganic c av ...201323673750
assessing the costs and benefits of an oral vaccine for raccoon rabies: a possible model.any cost-benefit analysis of the use of an oral vaccine to control raccoon rabies should include calculating both costs and benefits in terms of $/unit area. further, cost savings must be adjusted to match the stages of an epizootic: pre-epizootic, epizootic, and post-epizootic. a generic model, which can be adapted to different sites, illustrates the use of threshold analysis to link distribution costs, cost savings, bait density, and vaccine price. initial results indicate the need to lower th ...20138969251
the procyonid social club: comparison of brain volumes in the coatimundi (nasua nasua, n. narica), kinkajou (potos flavus), and raccoon (procyon lotor).the present study investigated whether increased relative brain size, including regional brain volumes, is related to differing behavioral specializations exhibited by three member species of the family procyonidae. procyonid species exhibit continuums of behaviors related to social and physical environmental complexities: the mostly solitary, semiarboreal and highly dexterous raccoons (procyon lotor); the exclusively arboreal kinkajous (potos flavus), which live either alone or in small polyand ...201324107681
development and characterization of polymorphic microsatellite markers for chinese raccoon dog (nyctereutes procyonoides procyonoides).chinese raccoon dog (nyctereutes procyonoides procyonoides) is one of the most important fur-bearing animal species. information about the genetic background of farmed chinese raccoon dogs is limited. in this study, 17 polymorphic microsatellite markers were isolated and identified from an (ac)n-microsatellite-enriched library of chinese raccoon dogs. the number of alleles per locus ranged from 2 to 8 based on 48 individuals tested. the expected and observed heterozygosity and polymorphism infor ...201324390984

population genetic study of the raccoon dog (nyctereutes procyonoides) in south korea using newly developed 12 microsatellite markers.the raccoon dog (nyctereutes procyonoides) is distributed from southeastern siberia to northern vietnam, including korea and japan, as well as europe. in korea, most of its predators and competitors are extinct, which has resulted in rapid growth of the raccoon dog population. this population increase has raised concerns about its role in the ecosystem and the zoonotic transfer of various contagious diseases, and thus an effective method of raccoon dog population control in korea is required. to ...201323676711
three-dimensional positioning of b chromosomes in fibroblast nuclei of the red fox and the chinese raccoon dog.great progress has been achieved over the last years in studies on chromosome arrangement in mammalian cell nuclei. growing evidence indicates that the genome's spatial organization is of functional relevance. so far, no attention has been paid to the nuclear organization of b chromosomes (bs). in this study we have examined nuclear positioning of bs in 2 species from the canidae family--the red fox and the chinese raccoon dog. using 2d and 3d fluorescence in situ hybridization and 2 gene-specif ...201323485799
species-specific differences in the accumulation features of organohalogen contaminants and their metabolites in the blood of japanese terrestrial mammals.residue levels and patterns of polychlorinated biphenyls (pcbs), polybrominated diphenyl ethers (pbdes), their hydroxylated metabolites (oh-pcbs, oh-pbdes), and methoxylated pbdes (meo-pbdes) in the blood of various terrestrial mammals in japan, including cats, raccoon dogs, dogs, masked palm civets, foxes, raccoons, badgers, and mongooses were determined. tri- through penta-chlorinated oh-pcbs were predominant in cat blood, whereas hexa- through octa-chlorinated oh-pcbs were found in other spec ...201323246744
evaluation of an elisa to detect rabies antibodies in orally vaccinated foxes and raccoon dogs sampled in the field.the assessment of the efficacy of oral vaccination in wildlife is based on detection in the teeth of a biomarker (tetracycline) which is incorporated in the vaccine bait, and the quantification of rabies antibodies. a blocking elisa was evaluated and compared with the favn test and a validated in-house elisa, using sera from foxes and raccoon dogs collected following oral vaccination campaigns in france and estonia. specificity reached 100% in sera from naïve animals. a high concordance (95%) wa ...201323201293
shape variation in the skull and lower carnassial in a wild population of raccoon dog (nyctereutes procyonoides).individual variations in skull and lower carnassial morphology within a wild population of raccoon dog were examined using geometric morphometric techniques. we compared individual morphological variations by using relative warp analysis, and then tested morphological integration between the skull and carnassial by using partial least square (pls) analysis. the most marked variation in skull shape was the dorsoventral flexion; i.e., deformation from klinorhynchy to airorhynchy. two remarkable va ...201323480380
large forest patches promote breeding success of a terrestrial mammal in urban landscapes.despite a marked increase in the focus toward biodiversity conservation in fragmented landscapes, studies that confirm species breeding success are scarce and limited. in this paper, we asked whether local (area of forest patches) and landscape (amount of suitable habitat surrounding of focal patches) factors affect the breeding success of raccoon dogs (nyctereutes procyonoides) in tokyo, central japan. the breeding success of raccoon dogs is easy to judge as adults travel with pups during the b ...201323300951
epidemiology of sarcoptic mange in free-ranging raccoon dogs (nyctereutes procyonoides) in yokohama, japan.free-ranging raccoon dogs (nyctereutes procyonoides) from nogeyama zoological gardens, kanazawa zoological gardens, and yokohama zoological gardens frequently rescued dogs having sarcoptes scabiei infestation. however, the epidemiology of s. scabiei infestation has not yet been elucidated. in the present study, we investigated the epidemiology of s. scabiei infestation in raccoon dogs and its influence on the population of masked palm civets in yokohama, japan. we examined records of raccoon dog ...201322902260
lessons from a non-domestic canid: joint disease in captive raccoon dogs (nyctereutes procyonoides).the purpose of this study was to describe pathological changes of the shoulder, elbow, hip and stifle joints of 16 museum skeletons of the raccoon dog (nyctereutes procyonoides). the subjects had been held in long-term captivity and were probably used for fur farming or research, thus allowing sufficient longevity for joint disease to become recognisable. the prevalence of disorders that include osteochondrosis, osteoarthritis and changes compatible with hip dysplasia, was surprisingly high. oth ...201323277118
raccoon social networks and the potential for disease transmission.raccoons are an important vector of rabies and other pathogens. the degree to which these pathogens can spread through a raccoon population should be closely linked to association rates between individual raccoons. most studies of raccoon sociality have found patterns consistent with low levels of social connectivity within populations, thus the likelihood of direct pathogen transmission between raccoons is theoretically low. we used proximity detecting collars and social network metrics to calc ...201324130746
numerical simulation of a susceptible-exposed-infectious space-continuous model for the spread of rabies in raccoons across a realistic landscape.we introduce a numerical model for the spread of a lethal infectious disease in wildlife. the reference model is a susceptible-exposed-infectious system where the spatial component of the dynamics is modelled by a diffusion process. the goal is to develop a model to be used for real geographical scenarios, so we do not rely upon simplifying assumptions on the shape of the region of interest. for this reason, space discretization is carried out with the finite element method on an unstructured tr ...201323157180
analysis of the reliability of clinical examination in predicting traumatic cerebral lesions and skull fractures in patients with mild and moderate head trauma.the aim of the study was to assess the reliability of neurological examination and other factors in predicting traumatic cerebral lesions and skull fractures in patients with mild and moderate head trauma (gcs 10-15).201324468590
effects of culling on mesopredator population dynamics.anthropogenic changes in land use and the extirpation of apex predators have facilitated explosive growth of mesopredator populations. consequently, many species have been subjected to extensive control throughout portions of their range due to their integral role as generalist predators and reservoirs of zoonotic disease. yet, few studies have monitored the effects of landscape composition or configuration on the demographic or behavioral response of mesopredators to population manipulation. du ...201323527065
panda sign due to severe coughing.we present the case of a patient who developed periorbital ecchymosis (panda sign) following an exacerbation of asthma with severe coughing. there was no history of cranial trauma. investigations for a structural or haematological cause were negative. the panda sign is typically seen following a base of skull fracture, but rarely reported due to severe coughing.201323516688

timing of puberty and its relationship with body growth and season in male raccoons (procyon lotor) in hokkaido.the raccoon (procyon lotor), indigenous to north america, has naturalized in japan as an invasive alien species, having been introduced into the country in the 1970s. in hokkaido, the northernmost island of japan, feral raccoons have been increasing in number and spreading throughout the island. the age at the onset of puberty for raccoons is important for estimating individual lifetime reproductive success and population growth. the present study investigated the timing of and potential factors ...201323603783
sphingomyelin lipidosis (niemann-pick disease) in a juvenile raccoon (procyon lotor).a wild caught juvenile male raccoon with neurological disease was humanely destroyed due to poor prognosis. necropsy examination revealed hepatomegaly, splenomegaly and multicentric lymphadenomegaly with diffuse hepatic pallor and pulmonary consolidation with pinpoint pale subpleural foci. microscopically, there was marked pale cytoplasmic swelling of the central and peripheral neurons as well as the glial cells in the brain, accompanied by multiorgan infiltration by abundant foamy macrophages. ...201323582974
oral rabies vaccination variation in tetracycline biomarking among ohio raccoons.oral rabies vaccination (orv) programs have traditionally relied on tetracycline marking as an index to bait uptake. whether tetracycline serves well in this capacity depends on its deposition affinity and ability to be detected consistently among tissues selected for analysis from target species. we evaluated samples from 760 hunter-harvested raccoons (procyon lotor) from areas in ohio where orv had been conducted during 1998, 1999, and 2001. tetracycline marking was evaluated within and among ...201323568908
dynamic regression modeling of daily nitrate-nitrogen concentrations in a large agricultural watershed.nitrate-nitrogen concentrations in rivers represent challenges for water supplies that use surface water sources. nitrate concentrations are often modeled using time-series approaches, but previous efforts have typically relied on monthly time steps. in this study, we developed a dynamic regression model of daily nitrate concentrations in the raccoon river, iowa, that incorporated contemporaneous and lags of precipitation and discharge occurring at several locations around the basin. results sug ...201323054269
isolation of deer tick virus (powassan virus, lineage ii) from ixodes scapularis and detection of antibody in vertebrate hosts sampled in the hudson valley, new york state.deer tick virus, dtv, is a genetically and ecologically distinct lineage of powassan virus (powv) also known as lineage ii powv. human incidence of pow encephalitis has increased in the last 15 years potentially due to the emergence of dtv, particularly in the hudson valley of new york state. we initiated an extensive sampling campaign to determine whether powv was extant throughout the hudson valley in tick vectors and/or vertebrate hosts.201324016533
distribution of wild mammal assemblages along an urban-rural-forest landscape gradient in warm-temperate east asia.urbanization may alter mammal assemblages via habitat loss, food subsidies, and other factors related to human activities. the general distribution patterns of wild mammal assemblages along urban-rural-forest landscape gradients have not been studied, although many studies have focused on a single species or taxon, such as rodents. we quantitatively evaluated the effects of the urban-rural-forest gradient and spatial scale on the distributions of large and mid-sized mammals in the world's larges ...201323741495
endoparasites of the raccoon dog (nyctereutes procyonoides) and the red fox (vulpes vulpes) in denmark 2009-2012 - a comparative study.invasive species negatively influence the biodiversity of the ecosystems they invade and may introduce pathogens to native species. raccoon dogs have very successfully invaded europe, including, recently, denmark. this study included analyses of gastrointestinal helminths and trichinella spp. from 99 raccoon dogs and 384 native red foxes collected from october 2009 to march 2012. the sedimentation and counting method used revealed that raccoon dogs and foxes harboured 9 and 13 different helminth ...201324533328

molecular characterization and phylogenetic analysis of babesia sp. nv-1 detected from wild american mink ( neovison vison ) in hokkaido, japan.babesiosis is a tick-borne protozoan disease affecting many mammalian species worldwide, caused by the intraerythrocytic multiplication of babesia spp. the present study aimed to detect the presence of babesia sp. in 13 american mink from hokkaido, japan. one of 13 animals was positive, as indicated by nested pcr targeting the 18s ribosomal rna (ssu rdna) and subunit 7 (eta) of the chaperonin-containing t-complex polypeptide 1 (cct7) genes from species of babesia and theileria. sequencing of the ...201322994135
parasites and the conservation of small populations: the case of baylisascaris procyonis.human demands on natural resources result in landscape changes that facilitate the emergence of disease. most emerging diseases are zoonotic, and some of these pathogens play a role in the decline of vulnerable wildlife species. baylisascaris procyonis, the common roundworm parasite of raccoons (procyon lotor), is a well recognized zoonotic infection that has many of the properties associated with a pathogen capable of driving extinction. it is highly non-specific and frequently pathogenic with ...201324533336
illegal wildlife imports more than just animals--baylisascaris procyonis in raccoons (procyon lotor) in norway.in autumn 2011, 11 illegally imported animals were seized from a farm in southern norway. these included four raccoon dogs (nyctereutes procyonoides), four raccoons (procyon lotor), and three south american coatis (nasua nasua), all considered alien species in norway. an additional two raccoons had escaped from the farm prior to seizure. the seized animals were euthanized and postmortem examination revealed that the four raccoons had moderate to high numbers of the zoonotic nematode baylisascari ...201324502726
baylisascaris procyonis infection in white-footed mice: predicting patterns of infection from landscape habitat attributes.there is a growing body of evidence that habitat fragmentation resulting from anthropogenic land use can alter the transmission dynamics of infectious disease. baylisascaris procyonis , a parasitic roundworm with the ability to cause fatal central nervous system disease in many mammals, including humans, is a zoonotic threat, and research suggests that parasite recruitment rates by intermediate hosts are highly variable among forest patches in fragmented landscapes. during 2008, we sampled 353 w ...201323656487
use of experimental translocations of allegheny woodrat to decipher causal agents of decline.translocations are an important tool for wildlife conservation, although progress in the field of reintroduction biology has been hindered by the ad hoc and opportunistic nature of many translocations. we used an experimental translocation to elucidate the role of raccoon roundworm (baylisascaris procyonis) and inbreeding depression in the decline of the allegheny woodrat (neotoma magister), an endangered species. we translocated woodrats from genetically diverse populations in the core of the s ...201323647164
molecular analysis of baylisascaris columnaris revealed mitochondrial and nuclear polymorphisms.baylisascaris species are intestinal nematodes of skunks, raccoons, badgers, and bears belonging to the genus ascarididae. oral uptake of embryonated baylisascaris sp. eggs by a wide variety of mammals and birds can lead to visceral, ocular and neurological larva migrans. b. procyonis, the raccoon roundworm, is known to cause severe illness in intermediate hosts and in humans, whereas the skunk roundworm b. columnaris is probably less pathogenic. skunks and raccoons are kept as pets in europe, s ...201323627901
influence of environmental variables on baylisascaris procyonis infection in raccoons.baylisascaris procyonis is a zoonotic nematode commonly found in raccoons (procyon lotor). human-altered landscapes can support dense populations of raccoons, increasing the potential for interaction between humans and these animals. we used raccoon feces provided by licensed fur trappers to investigate environmental variables that influence prevalence of b. procyonis at 2 sites in wisconsin. trappers submitted raccoon feces to us, along with information on sex, age (juvenile and adult), and app ...201222568732

Role of multiple hosts in the cross-species transmission and emergence of a pandemic parvovirus.Understanding the mechanisms of cross-species virus transmission is critical to anticipating emerging infectious diseases. Canine parvovirus type 2 (CPV-2) emerged as a variant of a feline parvovirus when it acquired mutations that allowed binding to the canine transferrin receptor type 1 (TfR). However, CPV-2 was soon replaced by a variant virus (CPV-2a) that differed in antigenicity and receptor binding. Here we show that the emergence of CPV involved an additional host range variant virus tha ...201222072763
detection of anti-leptospira antibodies in captive nonhuman primates from salvador, brazil.leptospirosis is a widely distributed zoonosis that affects several species of domestic and wild animals. under captive conditions, leptospirosis is a potential problem because the physical conditions in most zoos and research centers cannot prevent the captive animals from being exposed to rodents, raccoons, opossums, and other local wildlife that are known carriers. yet, despite the potential risk, animals that are destined for reintroduction into the wild are not routinely tested for anti-lep ...201222052355
