Rift Valley fever viruses carrying mutations of the M gene preglycoprotein region, one lacking NSm protein expression, one lacking 78-kDa protein expression, and one lacking expression of both proteins, were compared in cell culture. All of the mutants and their parent virus produced plaques with similar sizes and morphologies in Vero E6 cells and had similar growth kinetics in Vero, C6/36, and...
background and aims: adventitious agents, especially viral agents are among the most important concerns in viral vaccines. viral contamination of biological products may arise from the original source of the reagents such as, serum, trypsin, animal or human derived media components or cell culture and working seed or cross contamination of vaccine during production. in this study, adventitious ...
Shiga-like toxin-producing (SLTEC) Escherichia coli strains are one of the most important food borne emerging pathogens. One hundred and fifty-seven E. coli strains isolated from 39 children with diarrhea of unknown origin and one hundred and five E. coli strains from 20 healthy children were examined for Shiga-like toxin production in Vero cell line assay. The synthesis of Shiga-like toxin was...
BACKGROUND To evaluate, in vitro, the potential cytotoxicity of three different dental adhesives systems (Adper Single Bond 2 -SB, Silorane System Adhesive Bond -SSAB and Single Bond Universal -SBU) on cultivated Vero cells after different contact times. MATERIAL AND METHODS The cells were cultured in a concentration of 2 x 105 cells/mL for 24h and grown to sub-confluent monolayers. VERO cell...
Background: Mycoplasma contamination in cell cultures is considered as a major economic, research and production problem. In this study, mycoplasma-infected Vero cell lines were treated by various dilutions of ciprofloxacin and enrofloxacin in a timely manner. Removal of mycoplasma contamination from infected cell cultures was evaluated and demonstrated by polymerase chain reaction (PCR) method...
The objective of our study was to examine fusional, hemolytic, hemagglutination and hemadsorption activities of the surface glycoprotein HN and F antigens of Newcastle disease (ND) virus, in vitro. The samples of activated ND virions, induced Vero cell fusion after 6h, 12h, 24h and 48h. After 24h of treatment of the inoculated Vero cells with dilutions of the specific immune sera against ND vir...
