Copper Deficiency Increases the Virulence of Coxsackievirus B3 Infections in Mice

Attenuated virulence of pleconaril-resistant coxsackievirus B3 variants.

Pleconaril (VP 63843) is a novel orally bioavailable small molecule with broad antipicornavirus (enterovirus and rhinovirus) activity. Ten independently derived pleconaril-resistant variants of coxsackievirus B3 were isolated from cell culture. The molecular basis of drug resistance and the biologic properties of the drug-resistant viruses were investigated. RNA sequence analysis revealed amino...

Coxsackievirus B3-associated panuveitis.

A 29-year-old woman suffered from headaches, diarrhoea, and high grade fever followed by a unilateral retinal vasculitis, papillitis, and chorioretinitis. Abnormal electrocardiographic findings and antibody titre dynamics strongly suggested a coxsackievirus B3 infection. With respect to prior observations on coxsackievirus B group associated uveitis this viral infection may be considered in pat...

Susceptibility to Coxsackievirus B3-Induced Myocarditis in Mice

Coxsackievirus B3 protease 3C induces cell death in eukaryotic cells

Abstract: Coxsackievirus B3 (CVB3) is the most common agent known to cause viral myocarditis. The viral genome encodes a single polyprotein that is cleaved to produce several proteins by virally encoded proteases. Most of this proteolytic processing is catalyzed by a cysteine protease called 3C. The 3C protease plays major role in viral replication and cellular damage. To understand the mecha...

RT-PCR Detection of Coxsackievirus B3: A Viral Myocarditis

Backgrounds and Aims: Coxsakievirus B3 (CVB3), one of the six Coxsakievirus B serotypes, is a member of the Enterovirus genus within the Picornaviridae family. CVB3 is an important pathogen of viral myocarditis, which accounts for more than 50% of viral myocarditis cases. The genome of CVB3, like that of other Entroviruses, is a single-stranded, sense, polyadenylated RNA molecule with 7400 nucl...
