An attenuated EMCV-HB10 strain acts as a live viral vector delivering a foreign gene

An attenuated EMCV-HB10 strain acts as a live viral vector delivering a foreign gene.

We successfully constructed a full-length cDNA infectious clone of the encephalomyocarditis virus (EMCV) HB10 strain and obtained a partially attenuated rEMCV-C9 virus with a shorter poly(C) tract. Our results showed that the length of the EMCV-HB10 poly(C) tract was related to the pathogenicity of the EMCV-HB10 strain in vivo. Using pEMCV-C9 as the backbone, we constructed the novel viral vect...

Lactococcus lactis as a live delivery vector

Mucosal surfaces of the body provide a universal entry portal for all known and emerging infectious pathogenic microbes. Therefore, it seems that special vaccination strategies are needed for vaccines that can hinder the entry capability of pathogenic microbes through the mucosal surfaces. Lactic acid bacteria are widely used in the food industry and are presently applied as delivery vehicles i...

Experimental study of a further attenuated live measles vaccine of the Sugiyama strain in Iran

Engineered and construction of pDS132::∆virG as suicide vector for targeted gene deletion of virG from Shigella flexneri 2a in order to generation a live attenuated Shigella vaccine

Background & Objective: Shigella are Gram negative bacteria capable of inducing their entry into non-phagocytic cells via secretion of various effector proteins called invasion plasmid antigens (Ipas). The most important of them is VirG protein. Live attenuated Shigella vaccines have indicated promise in inducing protective immune responses in human clinical trials. In current situation, const...
