Biotechnological methods offer promising approaches for improved diagnostic and prophylactic purposes. The following biotechnological techniques are used in the Institute of Virology at the Hanover Veterinary School:--Production of monoclonal antibodies directed against viral and bacteria-specific antigens such as bovine virus diarrhoea virus, classical swine fever (hog cholera) virus, feline l...

in order to estimate the mean of maternal antibody in calves against bhv-1 (bovine herpes virus type 1), this study was carried out in a population of calves from non-vaccinated dairy cattle at 2 livestock in qazvin province. one hundred thirteen sera out of 512 were collected from 1-4 months unvaccinated calves. we used blocking –percentage of maternal antibodies against bhv-1, which obtained ...

background and aims: bovine leukaemia virus (blv) is an oncogenic member of the genus deltaretrovirus of the family retroviridae. blv is the causative agent of enzootic bovine leukaemia and infects cattle worldwide, imposing economic impact on the dairy cattle industry. the purpose of this study was to estimate the seroprevalence of blv in cattle in some provinces of iran. materials and methods...

1006 Emerging Infectious Diseases • Vol. 8, No. 9, September 2002 capture enzyme-linked immunosorbent assay) and reverse transcriptasepolymerase chain reaction (RT-PCR) tests for flaviviruses, alphaviruses, and Bunyamwera serogroup bunyaviruses were also negative. RT-PCR for Crimean-Congo hemorrhagic fever virus (C-CHFV) was positive. Tests for anti-C-CHFV–specific IgM antibody by indirect immu...

abstract background and aims: to identify and isolation of viruses a susceptible cell is need which can be primary or line. the use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. irkhbk cell line was originated from primary cells of bovine kidney by continuous passage. the aim of this study was to introduce the irkhbk cell lin...

results primary, secondary, and 3d structure of cchfv gn were obtained and pcr reaction with m13 forward and reverse primers confirmed the generation of recombinant bacmid dna harboring gn coding region under polyhedron promoter. conclusions characterization of the detailed structure of cchfv gn by bioinformatics software provides the basis for development of new experiments and construction of...

Composting has been used to dispose of animal mortalities and infected materials, such as manure feed, during major disease outbreaks. In this study, we adapted the plastic-wrapped mortality composting system developed by Canadian Food Inspection Agency 2004 highly pathogenic avian influenza outbreak compost swine mortalities. The goals study were evaluate performance field test its ability eli...

results upon the results from literature search, the researchers found that human is the main reservoir for this virus. there are four serotypes of virus. infection with one serotype cannot protect human against the other three serotypes. dengue fever begins suddenly with an onset of an influenza-like syndrome and sometimes progresses to severe form of the disease. treatment is supportive and i...

The genus Pestivirus of the family Flaviviridae consists of four recognized species: Bovine viral diarrhoea virus 1 (BVDV-1), Bovine viral diarrhoea virus 2 (BVDV-2), Classical swine fever virus (CSFV) and Border disease virus (BDV). Recently, atypical pestiviruses ('HoBi'-like pestiviruses) were identified in batches of contaminated foetal calf serum and in naturally infected cattle with and w...

Paramyxoviruses are important pathogens affecting various animals, including humans. In this study, we identified a paramyxovirus in 2004 (180608_2004), isolated from sample of the femoral marrow bone wild boar carcass imported Australia. Antigenic and morphological characteristics indicated that virus was similar to members family Paramyxoviridae. The complete genome phylogenetic analysis grou...
