| survival and immunization of raccoons after exposure to pseudorabies (aujeszky's disease) virus gene-deleted vaccines. | in a controlled experiment, 16 wild-trapped raccoons were exposed to 1 of 2 genetically modified live pseudorabies virus (prv) vaccines used in swine. one vaccine had genes deleted for thymidine kinase (tk(-)) and glycoprotein g (gg(-)); the other had an additional deletion for glycoprotein e (ge(-)). these vaccines were administered orally and intranasally at four dose levels: 10(3), 10(4), 10(5), and 10(6) tcid(50). the 21 days survival rate was 37.5% for the gg(-)tk(-) vaccine; all of the sur ... | 2003 | 12488067 |
| application of phylogeny reconstruction and character-evolution analysis to inferring patterns of directional microbial transmission. | i used phylogenetic analyses to reconstruct patterns of directional interspecific transmission during a pseudorabies virus outbreak in illinois, usa, in 1989. isolates were recovered from five species: cattle, sheep, goats, pigs, and raccoons (procyon lotor). i generated dna sequences for 16 isolates of pseudorabies virus at the glycoprotein c gene, from which i constructed phylogenetic trees. i then used these trees, in combination with parsimony-based analyses of character evolution, to infer ... | 2003 | 14516717 |
| pathological findings in the red fox (vulpes vulpes), stone marten (martes foina) and raccoon dog (nyctereutes procyonoides), with special emphasis on infectious and zoonotic agents in northern germany. | anthropogenic landscape changes contributed to the reduction of availability of habitats to wild animals. hence, the presence of wild terrestrial carnivores in urban and peri-urban sites has increased considerably over the years implying an increased risk of interspecies spillover of infectious diseases and the transmission of zoonoses. the present study provides a detailed characterisation of the health status of the red fox (vulpes vulpes), stone marten (martes foina) and raccoon dog (nyctereu ... | 2017 | 28399176 |
| host and viral traits predict zoonotic spillover from mammals. | the majority of human emerging infectious diseases are zoonotic, with viruses that originate in wild mammals of particular concern (for example, hiv, ebola and sars). understanding patterns of viral diversity in wildlife and determinants of successful cross-species transmission, or spillover, are therefore key goals for pandemic surveillance programs. however, few analytical tools exist to identify which host species are likely to harbour the next human virus, or which viruses can cross species ... | 2017 | 28636590 |
| [incidence of antibodies in raccoon dogs and deer inhabiting suburban areas]. | we evaluated the incidence of antibodies against canine distemper (cd) virus, canine parvovirus, toxoplasma gondii (t. gondii), aujeszky's disease virus, porcine reproductive and respiratory syndrome virus, rickettsia tsutsugamushi, rickettsia japonica, and coxiella burnetii in 30 raccoon dogs and 5 deer captured in suburban areas in kanagawa prefecture. among the raccoon dogs, anti-t. gondii antibody was detected in 1 animal (3.3%) and anti-cd virus antibody in 9 (30.0%). however, antibodies ag ... | 1998 | 9621559 |
| a field trial to determine the feasibility of delivering oral vaccines to wild swine. | a field study was conducted on ossabaw island, georgia (usa) to determine the feasibility of delivering oral vaccines to wild swine (sus scrofa). baits were made of polymerbound fish meal and contained a gelatin capsule as a potential vaccine chamber. two biomarkers, iophenoxic acid and tetracycline, were incorporated into each bait, and soured chicken mash was used as an attractant. baits (n = 1,980) were distributed in a grid pattern on a 405-ha test site and monitored for animal disturbance. ... | 1990 | 2174467 |
| serologic survey for selected infectious disease agents in raccoons from illinois. | the determination of serologic titers to infectious organisms is a valuable tool for quantitating exposure to disease organisms. raccoons (procyon lotor) were live-trapped from september 1989 to october 1993 and samples collected from two distinct locations in west-central illinois (usa); a state recreational facility (park) and privately owned farming property (farm). sera were submitted for testing leptospira interrogans (serovars bratislava, canicola, grippotyphosa, hardjo, icterohemmorhagiae ... | 1999 | 10231761 |
| pseudorabies virus infection in raccoons: a review. | pseudorabies is a rarely reported disease of raccoons. laboratory and field evidence of prv infection suggests the raccoon is a "dead end" host with little opportunity for raccoon-to-raccoon spread of virus. all reported field cases have been associated closely with infected swine and swine have been considered the source of the raccoon infection. the clinical signs of prv in raccoons closely resembles those of canine distemper and rabies virus infections. infection with the latter viruses are c ... | 1982 | 6285008 |
| role of the raccoon in the transmission of pseudorabies: a field and laboratory investigation. | serum samples were collected from 42 raccoons trapped in a pseudorabies enzootic area of missouri. all samples were negative for neutralizing antibodies to pseudorabies virus (prv). raccoons were orally exposed with one of four dose levels of prv. the raccoons were found to be susceptible to moderately large doses of prv tissue culture infective dose (10(4) - 10(5) tcid50). all raccoons given 10(3) tcid50 of prv survived and did not develop clinical signs. the prv was consistently isolated from ... | 1980 | 6250423 |
| possible role of wild mammals in transmission of pseudorabies to swine. | of 73 wild and domestic mammals tested from an area endemic for pseudorabies in swine, 16 showed natural pseudorabies virus infection, 8 from farms with no pseudorabies history. in transmission experiments with swine and raccoons (procyon lotor), pseudorabies was not transmitted between raccoons but was transmitted reciprocally between raccoons and swine by contact and when either consumed infected carrion of the other. the fluorescent antibody tissue section test proved valuable in diagnosis of ... | 1980 | 6257934 |
| pseudorabies: experimental studies in raccoons with different virus strains. | raccoons (procyon lotor) were infected by the nasal/oral route with as little as 10(2) plaque forming units (pfu) of pseudorabies virus (prv). there was no apparent difference in the susceptibility of raccoons to infection with either of two virulent field strains or with the naturally avirulent k strain which has been used in modified live virus vaccines. each of these three viruses was transmitted by contact to uninfected raccoons. all raccoons that were infected with virulent field strains di ... | 1983 | 6315973 |
