a study to evaluate non-fatal rabies in animals.brains and salivary glands of stray dogs, cats and wild mammals were examined for latent rabies virus. sera of these animals were tested for rabits neutralizing antibody. dogs and rodents of the gerbil species were experimentally infected with rabies viruses tryping to produce nonfatal rabies. the following conclusions are made: 1. naturally occurring nonfatal rabies infection evidenced by recovery of the virus was not present in the stray dogs examined and could not be produced experimentally. ...1979387971

practical significance of rabies antibodies in cats and dogs.doubt has sometimes been cast upon the protective effect of rabies antibodies in serum. animals and humans suffering from fatal rabies often produce high antibody titres, while rabies cases are also observed in vaccinated animals. cellular immunity is also largely involved in protection. nevertheless, a large number of laboratory experiments and field observations clearly demonstrate that cats and dogs which develop antibodies after vaccination and before challenge have a very high probability o ...19921472723
an epidemic of sylvatic rabies in finland--descriptive epidemiology and results of oral vaccination.when rabies reappeared in finland in april 1988, the country had been rabies free since 1959. soon a picture of sylvatic rabies become evident, its main vector and victim being the raccoon dog (nyctereutes procyonoides). between 8 april 1988 and 16 february 1989, 66 virologically verified cases were recorded (48 raccoon dogs, 12 red foxes, 2 badgers, 2 cats, 1 dog and 1 dairy bull) in an area estimated at 1700 km2 in south-eastern finland. the greatest distance between recorded cases was 67 km. ...19921598857

retrospective: animal attacks and rabies exposures in thai children.over 50% of animal bites and potential rabies exposures in thailand are in children and they also have the more severe injuries due to inexperience, smaller size and less ability to fend off attacks. potential rabies exposures and animal bites are common in thailand. majority of these are in children where the extent of the injuries is also much more severe. the bitten areas correlate to the age of the children and level of the bitten animal head. these are areas noted for a higher risk of infec ...200616905457

investigating antibody neutralization of lyssaviruses using lentiviral pseudotypes: a cross-species comparison.cross-neutralization between rabies virus (rabv) and two european bat lyssaviruses (eblv-1 and -2) was analysed using lentiviral pseudotypes as antigen vectors. glycoprotein (g-protein) cdna from rabv challenge virus standard-11 (cvs-11) and eblv-1 and -2 were cloned and co-expressed with human immunodeficiency virus (hiv) or murine leukemia virus (mlv) gag-pol and packageable green fluorescent protein (gfp) or luciferase reporter genes in human cells. the harvested lentiviral (hiv) vector infec ...200818753230
rabies awareness in eight asian countries.rabies is a deadly zoonotic disease most often transmitted to humans through a dog bite. human mortality from endemic canine rabies is estimated by who to be around 55,000 deaths annually, with over 31,000 deaths in asia alone, mostly children. most of these deaths could be prevented through post-exposure prophylaxis (pep), including immediate wound washing, rabies immunoglobulin administration and vaccination. unfortunately, at-risk populations are not well-informed of the risk of rabies and wh ...200818804507
localization of serotoninergic neurons that participate in regulating diaphragm activity in the cat.although a considerable body of literature indicates that serotoninergic neurons affect diaphragm activity both through direct inputs to phrenic motoneurons and multisynaptic connections involving the brainstem respiratory groups, the locations of the serotoninergic neurons that modulate breathing have not been well defined. the present study identified these neurons in cats by combining the transneuronal retrograde transport of rabies virus from the diaphragm with the immunohistochemical detect ...200919433074
feline rabies. abcd guidelines on prevention and management.overview: rabies virus belongs to the genus lyssavirus, together with european bat lyssaviruses 1 and 2. in clinical practice, rabies virus is easily inactivated by detergent-based disinfectants. infection: rabid animals are the only source of infection. virus is shed in the saliva some days before the onset of clinical signs and transmitted through a bite or a scratch to the skin or mucous membranes. the average incubation period in cats is 2 months, but may vary from 2 weeks to several months, ...200919481038

distribution of hypothalamic neurons with orexin (hypocretin) or melanin concentrating hormone (mch) immunoreactivity and multisynaptic connections with diaphragm motoneurons.prior work showed that neurons in the lateral, dorsal, and perifornical regions of the tuberal and mammillary levels of the hypothalamus participate in the control of breathing. the same areas also contain large numbers of neurons that produce either orexins (hypocretins) or melanin concentrating hormone (mch). these peptides have been implicated in regulating energy balance and physiological changes that occur in transitions between sleep and wakefulness, amongst other functions. the goal of th ...201020144885

complete genome sequences of four virulent rabies virus strains isolated from rabid animals in russia.rabies virus (rabv) strains rus(lipetsk)-8052f, rus(lipetsk)-8053c, rus(lipetsk)-8054f, and rus(lipetsk)-8057f were isolated from foxes (vulpes vulpes) and a cat (felis catus) in the lipetsk region of russia in 2011. close relationships between these strains and the members of the "cosmopolitan" group from russia (98% homology) and from europe (95% homology) were estimated.201323661472
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 ...201728636590
an assessment of shedding with the oral rabies virus vaccine strain spbn gasgas in target and non-target species.a safety requirement for live vaccines is investigating possible shedding in recipients since the presence of replication competent vaccine in secretions could result in direct and indirect horizontal transmission. this is especially relevant for oral rabies vaccine baits that are deliberately distributed into the environment. in the current study, survival of an oral rabies virus vaccine, spbn gasgas, was examined in excretions from different target and non-target species; red fox, raccoon dog, ...201829325820
