Thirteen serum samples from nine children with Kawasaki disease and 23 control samples gave negative results on screening for antibodies to hog cholera virus, border disease of sheep, bovine diarrhoea virus, and equine arteritis virus. The sera from two children with Kawasaki disease were cytotoxic; a possible link with cytotoxin from Propionibacterium acnes is considered.

Bovine virus diarrhoea virus (BVDV) infection of cattle results in a wide range of clinical manifestations. This article reviews the clinical responses associated with BVDV and discusses these diseases in terms of acute infection in immunocompetent cattle, fetal infection, infection in cattle immunotolerant to and persistently infected with BVDV and finally mucosal disease.

the present study was carried out for the antigen detection of feline panleukopenia virus (fpv) in diarrhoeic cats referred to the veterinary clinic of the school of ahvaz university, in southwest iran. faecal samples were collected from 67 diarrhoeic household cats during 2005 to 2007. according to the age and clinical signs, the cats were divided into two groups; 6 months, hemorrhagic and ...

a rapid and sensitive reverse transcription polymerase chain reaction (rt-pcr) and nested-pcr were used to detect bovine viral diarrhea virus 1 (bvdv-1) in bull semen. selected primers could amplify a part of the 5´utr of the bvdv genome. a 294 bp dna fragment was amplified and specificity of the results was confirmed by direct sequencing of the pcr product. prior to rna extraction, the seminal...

the objective of this study was to compare different antigen preparations to produce monoclonalantibodies against bovine leukaemia virus gp51su. the four antigen preparations for immunization ofbalb/c mice were: cl: blv-flk cell lysate, uf: a fraction of cl (between 30 and 100 kda), wvp: wholevirus particles and sp: with ion exchange chromatography, gp51su was semipurified. a total of ninesucce...

IN the 15 years since the last In Practice article on bovine virus diarrhoea virus (BVDV) (Brownlie 1985), there has been an explosion in the understanding of the molecular mechanisms of viral replication and mutation, especially those related to biotypic variation. Hand in hand has come a greater understanding of the importance of BVDV as a primary pathogen of cattle, particularly as a cause o...

This final chapter highlights the advances and some of the unanswered questions concerning bovine virus diarrhoea virus (BVDV) presented in this Review by specialists from around the world. Persistently viraemic cattle play an essential role in the dissemination of BVDV but it is suggested that acute infections with the virus are also important. The role of latency is considered but, as yet, th...

Two enzyme-linked immunosorbent assays (ELISAs) for the diagnosis of bovine virus diarrhoea (BVD) are described: CHEKIT-BVD-VIRUS and CHEKIT-BVD-SERO. The first test detects virus antigen in leucocytes, resulting in identification of persistently-infected animals, while the second detects antibodies to BVD virus (BVDV). It is well known that even persistently-infected animals may have antibodie...
