A viral agent was isolated from the trachea of a lamb that was suffering from a respiratory disorder. The physical and chemical properties of the isolates are characteristic of the herpesvirus group. It contains DNA in its virion, is ether sensitive, acid labile at pH 3.0 and heat labile at 56 degrees C after five minutes. The cytopathology observed provided further evidence of a herpesvirus isolate. The neutralization of the infectivity of the isolate with antiserum to bovine herpesvirus 1 is evidence that it should be considered an isolate of bovine herpesvirus 1. It is concluded that this is a report of a bovine herpesvirus infection in sheep. 相似文献

A herpesvirus was isolated from the feces of a cow with diarrhea. The viral isolate was identified as a herpesvirus on the basis of morphology and chloroform sensitivity. It was serologically distinct from bovine Herpesvirus I (IBR) and II (mammillitis virus) as well as equine herpesviruses and pseudorabies virus. It was serologically related to members of the bovine Herpesvirus III group.Experimentally inoculated calves developed a transient fever but no other clinical signs or lesions. The virus could be re-isolated from the calves and significant levels of virus neutralizing antibodies were present in the serum 40 days after inoculation. 相似文献

Isolation of a herpesvirus serologically related to bovine herpesvirus 1 from a reindeer (Rangifer tarandus) 总被引：2，自引：0，他引：2
Serological evidence of exposure of reindeer (Rangifer tarandus) to a virus related to bovine herpesvirus 1 (BHV1) (Synonym: Infectious bovine rhinotracheitis (IBR) virus) has been reported in Canada (El Azhary 1979) and the USA (Dieterich 1981). A serological survey conducted in Finnish Lapland also detected neutralising antibodies to BHV1 in reindeer sera; 23 % of 300 reindeer had detectable antibodies, whereas none of 300 cattle sera from the same region contained antibodies to BHV1 (Ek-Kommonen et al. 1982). There is currently no evidence of BHV1 infection of cattle in Finland, so the isolation and characterisation of the reindeer herpesvirus was of considerable interest. This short communication describes the isolation and preliminary characterisation of a herpesvirus from a reindeer following the administration of dexamethasone. 相似文献

Cloacal swabs collected from wild bald eagle nestlings (Haliaeetus leucocephalus) were tested for viruses. A virus isolated from one of these samples had a lipid coat and contained DNA. Electron microscopy confirmed that it was a herpesvirus. This appears to be the first report of a herpesvirus isolation from a wild bald eagle. 相似文献

Five kittens exposed neonatally to older cats exhibiting fever with nasal and ocular discharge became ill and died within 10 days of the onset of illness. One kitten which died at 16 days old was examined post mortem and feline herpesvirus 1 was isolated from the brain, liver, lung and spleen. 相似文献

Feline herpesvirus infection is an extremely common disease and leads to ocular problems in a large percentage of affected cats. Feline herpesvirus-1 is maintained within the feline population by ready transmission from cat to cat, ensuring continued exposure of kittens and adults. The virus is similar in structure and pathogenicity to herpes simplex virus in humans. Both viruses are members of the family Herpes-viridae and subfamily Alphaherpesviridae. The hallmark of this family of herpesviruses is latency that develops after primary infection. This factor is clinically important because disease may recur at later points in life without further exposure to the virus. Conjunctivitis and corneal ulcers are particularly common forms of feline herpesvirus-1 recurrence. 相似文献

Feline herpesvirus (FHV-1; felid herpesvirus 1 (FeHV-1)) is an alphaherpesvirus of cats closely related to canine herpesvirus-1 and phocine herpesvirus-1. There is only one serotype of the virus and it is relatively homogenous genetically. FeHV-1 is an important cause of acute upper respiratory tract and ocular disease in cats. In addition, its role in more chronic ocular disease and skin lesions is increasingly being recognised. Epidemiologically, FeHV-1 behaves as a typical alphaherpesvirus whereby clinically recovered cats become latently infected carriers which undergo periodic episodes of virus reactivation, particularly after a stress. The primary site of latency is the trigeminal ganglion. Conventional inactivated and modified-live vaccines are available and protect reasonably well against disease but not infection, although viral shedding may be reduced. Genetically engineered vaccines have also been developed, both for FeHV-1 and as vector vaccines for other pathogens, but none is as yet marketed. 相似文献

Psittacid herpesvirus (PsHV) was isolated from 41 birds kept in captivity in Belo Horizonte, Minas Gerais/Brazil using chicken embryo fibroblasts (CEF) cell cultures. For this study, leukocytes or cloacal swabs of live birds were used. Also, portions of liver, spleen or kidney from birds collected at necropsy were utilized for these tests. PCR tests confirmed the presence of PsHV in 100% of samples. Thirty-three of the PCR products were sequenced and the results disclosed a 99% and 100% identity when compared with other sequences PsHV-1 (AY372243.1 and AF261756.1), previously deposited in GenBank. In addition, histopathology was performed and 19 of the 29 birds contained random multifocal lymphoplasmacytic hepatitis with necrotic foci, suggestive of viral infection. Three samples were examined by electron microscopy to visualize the viral particles obtained from cell culture. The viral structures measured 269 nm in average, had envelopes with an icosahedral capsid and tegument, consistent with herpesvirus. Thus, a total of 41 isolates were obtained from PsHV cell cultivation in CEF, confirming the circulation of the virus between parrots kept in captivity in Belo Horizonte, and affirming the importance of further studies in this area. 相似文献

Four genotypes of the psittacid herpesvirus (PsHV) cause Pacheco disease in parrots. Viruses that are serologically cross-reactive to the PsHVs have also been isolated from passerine species. DNA was amplified from a herpesvirus isolated from a superb starling (Lamprotornis superbus) with PsHV-specific primers and polymerase chain reaction. A comparison of the partial sequence of the UL 16 gene from this herpesvirus with sequences from viruses of known PsHV genotypes showed that the herpesvirus from the superb starling was a PsHV genotype 1 virus. This finding expands the range of birds that are known to be susceptible to PsHV genotype 1 infections and suggests that PsHVs should be considered as a differential in passerines with herpesvirus infections. 相似文献

Feline herpesvirus infection is extremely common and may lead to recurring ocular disease in the adult cat. Recognition of the history and clinical signs that are consistent with FHV-1 infection is critical because diagnostic tests may be negative. Although a variety of treatment options are available, no one therapy is successful in every cat, and a small percentage of cats respond poorly to any treatment. 相似文献
