چکیده

This paper describes the construction and characterization of a Brazilian strain of bovine herpesvirus type 1.2a (BoHV-1.2a) with a deletion of the glycoprotein E (gE) gene. The deletion was introduced by cotransfection of a deletion fragment containing the 5 ́and 3 ́gE flanking regions and genomic DNA of wild type BoHV-1 into bovine cells. Isolation of gE deletion mutant was performed by immunoperoxidase staining with an anti-gE monoclonal antibody. Viral clones were plaque purified and further examined by restriction endonuclesase digestion and Southern blot hybridization. This gE deletion mutant will be evaluated as a vaccinal virus, in order to determine its potential use for a differential vaccine.

Construction and Characterization of a Bovine Herpesvirus 5 Mutant with a Deletion of the Gi, Ge and Us9 Genes

Bovine herpesvirus 5 (BoHV-5) is a important cause of viral encephalitis in cattle in South America. Within the framework of developing a differential vaccine against BoHV-5, a deletion mutant was constructed based on a Brazilian BoHV-5 isolate. The target of the deletions were genes that code proteins implicated in the neurovirulence of BoHV-5, the glycoprotein I (gI), glycoprotein E (gE) and ...

Construction of an iss deleted mutant strain from a native avian pathogenic Escherichia coli O78: K80 and in vitro serum resistance evaluation of mutant

BACKGROUND: Colibacillosis, caused by different serotypes of avian pathogenic Escherichia coli (APEC), is one of the important diseases in poultry industry. The isolate O78 is the most prevalent serotype of APEC in Iran. One of the APEC virulence factors, increased serum survival (iss) gene, is related to serum resistance. The usual form of colibacillosis in avian is extraintestinal, and serum ...

Bovine herpesvirus type 5 (BoHV-5) is an important pathogen of cattle in South America. We describe here the construction and characterization of deletion mutants defective in the glycoprotein E (gE) or thymidine kinase (TK) gene or both (gE/TK) from a highly neurovirulent and well-characterized Brazilian BoHV-5 strain (SV507/99). A gE-deleted recombinant virus (BoHV-5 gE) was first generated i...

Isolation and Characterization of a New Peroxisome Deficient CHO Mutant Cell Belonging to Complementation Group 12

We searched for novel Chinese hamster ovary (CHO) cell mutants defective in peroxisome biogenesis by an improved method using peroxisome targeting sequence (PTS) of Pex3p (amino acid residues 1–40)-fused enhanced green fluorescent protein (EGFP). From mutagenized TKaEG3(1–40) cells, the wild-type CHO-K1 stably expressing rat Pex2p and of rat Pex3p(1–40)-EGFP, numerous cell colonies resistant to...
