background and aims: rotaviruses are the main cause of gastroenteritis in the young of human and a variety of animals in the world. rotavirus g6 and g10 are the most prevalent genotypes in cattle worldwide, but are also found in human with possible origination from animals. materials and methods: in this work, we have detected the g6 and g10 genotypes of bovine rotaviruses isolated from diarrhe...
The outer capsid protein of rotavirus, VP7, is a major neutralization antigen and is considered a necessary component of any subunit vaccine developed against rotavirus infection. For this reason, significant effort has been directed towards producing recombinant VP7 that maintains the antigenic characteristics of the native molecule. Using a relatively new expression system, the simple eukaryo...
Bluetongue is an economically major infectious, arthropod vector borne, viral disease of many free ranging and captive wild animals as well domestic animals. There are serotypes circulating in the world. The current study was undertaken having objective to characterize BTV 2(M11) isolate that engaged for vaccine trial. BHK21 cell lines were utilized cultivation serotype 2 followed by its RNA ex...
background: rotaviruses (rv) are important viral diarrheal agents in calves. vaccination is an optimum measure to prevent bovine rotaviruses (brv) infection. however, little research on brv vp7 vaccine has been done and currently there is no brv vaccine. objective: to prepare a subunit vaccine of brv and investigate its efficacy. methods: total rna was extracted from ma104 cells infected with b...
Background: Rotaviruses (RV) are important viral diarrheal agents in calves. Vaccination is an optimum measure to prevent bovine rotaviruses (BRV) infection. However, little research on BRV VP7 vaccine has been done and currently there is no BRV vaccine. Objective: To prepare a subunit vaccine of BRV and investigate its efficacy. Methods: Total RNA was extracted from MA104 cells infected with b...
The importance of VP7 of bluetongue virus (BTV) in the binding of BTV to membrane proteins of the BTV vector Culicoides variipennis was investigated. Core BTV particles, prepared from whole viruses, lacked outer proteins VP2 and VP5 and had VP7 exposed. More core particles and whole viruses bound to membrane preparations of adults of C. variipennis and KC cells, which were cultured from this ve...
Background and Aims: Rotavirus enteritis is an acute viral infectious disease among infants. VP7 protein has a key role in attachment and entry virus into the target cell. The VP7 protein is involved in inducing the production of neutralizing antibodies that protect infants against reinfection of the virus. The aim of this study was to heterologous expression of the VP7 gene of bovine rotavirus...

Rotavirus is a major cause of severe, dehydrating childhood diarrhea. VP7, the rotavirus outer capsid glycoprotein, is a target of protective antibodies and is responsible for the calcium-dependent uncoating of the virus during cell entry. We have purified, characterized, and crystallized recombinant rhesus rotavirus VP7, expressed in insect cells. A critical aspect of the purification is the e...
Background and Objectives Human rotavirus (RV) is responsible for most cases of acute gastroenteritis in infants, worldwide. Today, in vitro transcription (IVT) assay is widely used to develop efficient RNA for the biological experiments such as gene function analysis and reverse genetics. The aim of this study was to develop optimal full-length transcripts of the VP7 segment, using in vitro tr...
