visceral larva migrans induced eosinophilic cardiac pseudotumor: a cause of sudden death in a child.a case of fatal cardiac larva migrans in a 10-year-old boy is described. the autopsy findings were quite dramatic, with a bosselated, sessile polypoid mass involving the left ventricular myocardium and protruding into the ventricular lumen. the precise morphologic characterization of the zoonotic ascarid larva was impaired by advanced resorption of the larva by an inflammatory infiltrate. nonetheless, morphometry of the larval remnants strongly suggested the raccoon ascarid, baylisascaris procyo ...19958522917
diffuse unilateral subacute neuroretinitis. morphometric, serologic, and epidemiologic support for baylisascaris as a causative agent.several nematodes have been postulated as etiologic agents in diffuse unilateral subacute neuroretinitis (dusn), but the cause of this condition remains uncertain. the authors report the first case of dusn from the western united states (northern california), along with morphometric, serologic, and epidemiologic evidence supporting baylisascaris procyonis as its cause.19938233397
identification of opossums (didelphis virginiana) as the putative definitive host of sarcocystis neurona.sarcocystis neurona is an apicomplexan that causes equine protozoal myeloencephalitis (epm) in north and south america. horses appear to be an aberrant host, because the merozoites continually divide in the central nervous system, without encysting. the natural host species has not previously been identified. the small subunit ribosomal rna (ssurna) gene of s. neurona was compared to those of sarcocystis muris, sarcocystis cruzi, toxoplasma gondii, and cryptosporidium parvum to identify a unique ...19958544064
the relationship between capsid protein (vp2) sequence and pathogenicity of aleutian mink disease parvovirus (adv): a possible role for raccoons in the transmission of adv infections.aleutian mink disease parvovirus (adv) dna was identified by pcr in samples from mink and raccoons on commercial ranches during an outbreak of aleutian disease (ad). comparison of dna sequences of the hypervariable portion of vp2, the major capsid protein of adv, indicated that both mink and raccoons were infected by a new isolate of adv, designated adv-tr. because the capsid proteins of other parvoviruses play a prominent role in the determination of viral pathogenicity and host range, we decid ...19968551624
molecular phylogeny of the red panda (ailurus fulgens).the phylogenetic placement of the red panda (ailurus fulgens) and the giant panda (ailuropoda melanoleuca) has been an evolutionary enigma since their original descriptions in the nineteenth century. a series of recent molecular analyses led to a consensus that the giant panda's ancestors were derived from early bears (ursidae), but left unsettled the phylogenetic relationship of the red panda. previous molecular and morphological phylogenies were inconclusive and varied among placement of the r ...19958568209
rabies virus antinucleoprotein antibody protects against rabies virus challenge in vivo and inhibits rabies virus replication in vitro.we previously reported that a/wysnj mice vaccinated via a tail scratch with a recombinant raccoon poxvirus (rcn) expressing the rabies virus internal structural nucleoprotein (n) (rcn-n) were protected against a street rabies virus (d. l. lodmell, j. w. sumner, j.j. esposito, w.j. bellini, and l. c. ewalt, j. virol. 65:3400-3405, 1991). to improve our understanding of the mechanism(s) of this protection, we investigated whether sera of a/wysnj mice that had been vaccinated with rcn-n but not cha ...19938371354

enhanced production of morbillivirus gene-specific rnas following induction of the cellular stress response in stable persistent infection.previous in vitro work demonstrated the incorporation of the major inducible 70k heat shock protein (i.e., 72k hsp) into the biologically active light nucleocapsid (l-nc) variant of canine distemper virus (cdv). here, in vitro induction of the cellular stress response, characterized by elevated cytoplasmic and intranuclear 72k hsp, enhanced l-nc expression in mink lung cells supporting stable persistent infection by raccoon-origin cdv. increases in l-nc were correlated to increased viral rna pro ...19938421900
ageing, infecundity and reproductive senescence in free-ranging female rhesus monkeys.the reproductive performance of 760 free-ranging female rhesus monkeys (macaca mulatta), 168 of whom were 20 years of age and older at the time observations were begun, was assessed. the monkeys were resident on raccoon key or key lois, two islands located in the florida keys, usa. during 1992 and 1993, live birth rates generally declined with age among the raccoon and lois females aged eight years and older. this age-related deterioration of female fertility was the result of proportionately mo ...19958568771
analyses of mammalian sera in enzyme-linked immunosorbent assays with different strains of borrelia burgdorferi sensu lato.blood samples were collected from cottontail rabbits (sylvilagus floridanus), raccoons (procyon lotor), white-footed mice (peromyscus leucopus), and white-tailed deer (odocoileus virginianus) between 1977 and 1991 in southern connecticut and new york state (usa) and were tested for antibodies against eight strains of borrelia burgdorferi sensu lato in enzyme-linked immunosorbent assays. among these spirochetes were six strains of b. burgdorferi sensu stricto, one strain of b. garinii (=ip90) and ...19958583632
basilar arteries of the brain in raccoon dog (nyctereutes procyonoides (gray, 1834)).observations carried out on 43 brains of raccoon dogs show that the system of basilar arteries of the brain is similar to that in other carnivores. the observed differences were manifested in different vessel connections and occurrence of some variations. in 53.4% cases the basilar artery in raccoon dogs develops from the combination of the even ventral spinal arteries and the vertebral arteries entering them. an unusual case of the reduction of spinal artery was also found.19948590903
reactivity of white-footed mouse and raccoon sera to whole cell and recombinant antigens of borrelia burgdorferi.serum samples were collected from white-footed mice (peromyscus leucopus) and raccoons (procyon lotor) during 1983, 1984, and 1990 through 1993 in connecticut (usa) and were tested in enzyme-linked immunosorbent assays (elisa) against whole cell borrelia burgdorferi sensu stricto (strain 2591) and the following recombinant antigens of this spirochete: p41-g (an immunogenic epitope of flagellin), outer surface protein (osp)a, and ospb. antibodies were most frequently detected when whole cell anti ...19958592354
herpesvirus-like infection in a raccoon (procyon lotor).during march 1990, a subadult raccoon found dead in northeastern pennsylvania (usa) had gross lesions of multifocal hepatitis. microscopically, multifocal randomly distributed areas of acute necrosis with intranuclear viral inclusions were seen in liver, spleen, adrenal glands, and tongue. ultrastructural and immunoperoxidase results of formalin fixed liver were compatible with herpesvirus infection. this virus could be unique to the raccoon or may have been acquired from another species.19958592369
rabies postexposure prophylaxis--connecticut, 1990-1994.in connecticut, the first case of animal rabies associated with the ongoing raccoon rabies epizootic was identified in march 1991; since then, cases of animal rabies have been confirmed in all eight counties of the state. because of heightened awareness of the potential for rabies and the nearly always fatal outcome of this disease, the numbers of persons in connecticut receiving rabies postexposure prophylaxis (pep) was suspected to have increased substantially during 1990-1994. in connecticut, ...19968606682
raccoon poxvirus feline panleukopenia virus vp2 recombinant protects cats against fpv challenge.an infectious raccoon poxvirus (rcnv) was used to express the feline panleukopenia virus (fpv) open reading frame vp2. the recombinant, rcnv/fpv, was constructed by homologous recombination with a chimeric plasmid for inserting the expression cassette into the thymidine kinase (tk) locus of rcnv. expression of the vp2 dna was regulated by the vaccinia virus late promoter p11. southern blot and polymerase chain reaction (pcr) analyses confirmed the cassette was in the tk gene of the rcnv genome. ...19968615030
efficacy of six anthelmintics against luminal stages of baylisascaris procyonis in naturally infected raccoons (procyon lotor).the efficacy of six anthelmintics against natural infections of baylisascaris procyonis in raccoons (n = 7 per drug) was determined in a series of critical tests. the drugs were given via moist cat food as a single dose or once daily for three consecutive days. raccoons treated with pyrantel embonate (1 x 20 mg base kg-1 bodyweight (bwt.)), ivermectin (1 x 1 mg kg-1 bwt.), moxidectin (1 x 1 mg kg-1 bwt.), albendazole (3 x 50 mg kg-1 bwt.), fenbendazole (3 x 50 mg kg-1 bwt.) or flubendazole (3 x ...19958644451
experimental infection of the raccoon (procyon lotor) with borrelia burgdorferi.the reservoir competence of the raccoon (procyon lotor) for the lyme disease spirochete (borrelia burgdorferi) was evaluated in the laboratory during september 1991 to april 1993. five raccoons were exposed to spirochete-infected (jd1 and wisconsin 210 wise strains) ixodes scapularis nymphs (20/raccoon). a second feeding of spirochete-infected (wisconsin 210 wise strain) nymphs (20/raccoon) was performed with four of the original raccoons. xenodiagnosis with cohorts of i. scapularis larvae (300/ ...19968722269
pyogranulomatous peritonitis associated with nocardia sp.-like organisms in a raccoon (procyon lotor).during 1992 raccoons (procyon lotor) were live-trapped in northeastern pennsylvania (usa). in one of these animals a localized pyogranulomatous peritonitis was seen. grossly a large mass with a central area of liquifactive necrosis was present in the anterior abdomen. microscopically the lesion contained multiple colonies of filamentous organisms with histomorphologic and histochemical charcteristics resembling nocardia sp. this appears to be the first report of nocardia infection in the raccoon ...19968722283
the raccoon lateral cervical nucleus: mediolateral organization of gaba-positive and gaba-negative neurons and fibers.in the lateral cervical nucleus (lcn) of the cat, gaba-immunoreactive neurons and substance p-immunoreactive fibers are concentrated in the medial part of the nucleus, whereas in the monkey lcn no preferential locations have been identified. in raccoons, substance p-immunoreactive fibers display a distribution pattern similar to that in cats. however, the presence and distribution of gaba-immunoreactive neurons in the raccoon lcn has not been examined, and it is therefore not known whether racco ...19968729964
effects of melatonin implants on winter fur growth and testicular recrudescence in adult male raccoon dogs (nyctereutes procyonoides).the effects of melatonin implants were investigated on winter fur growth, monitored by counting growing and mature hairs per bundle and testicular recrudescence, judged by testis width, score count of spermatogenesis, and serum testosterone in the adult male raccoon dogs. melatonin administration in july highly elevated melatonin concentrations in serum and urine and induced an earlier decrease in prolactin secretion (august in the treated group vs september in the control group), winter fur gro ...19968797182
protection of cats from infectious peritonitis by vaccination with a recombinant raccoon poxvirus expressing the nucleocapsid gene of feline infectious peritonitis virus.feline infectious peritonitis virus (fipv) is a coronavirus that induces an often fatal, systemic infection in cats. various vaccines designed to prevent fipv infection have been shown to exacerbate the disease, probably due to immune enhancement mediated by virus-specific immunoglobulins against the outer envelope (s) protein. an effective vaccine would be one that induces cell-mediated immunity without disease enhancing antibodies. in this report, we describe the use of a recombinant raccoon p ...19958830483
