Replication of coxsackievirus B3 occurred for days in cultures of murine neonatal skin fibroblasts in the absence of cytopathology and resulted in alteration of the plasma membrane. Dual immunofluorescence studies showed that the lectin Ulex europaeus agglutinin I bound only to cells producing viral capsid antigens. Cultures of coxsackievirus B3-inoculated murine neonatal skin fibroblasts showe...

Swine vesicular disease virus (SVDV) emerged around 1960 from a human enterovirus ancestor, coxsackievirus B5 (CVB5), and caused a series of epizootics in Europe and Asia. We characterized a coxsackievirus B4 strain that caused an epizootic involving 24 488 pigs in the Soviet Union in 1975. Phylogenetic evidence suggested that the swine virus emerged from a human ancestor between 1945 and 1975,...

CONTEXT A variety of infectious agents have been reported as rare causes of acute pancreatitis. CASE REPORT We briefly describe a 36-year-old man who presented with acute pancreatitis and a maculopapular rash. The marked elevation in antibody titer against coxsackievirus B, as well as the skin biopsy, was compatible with acute coxsackievirus B viral infection. CONCLUSION This case highlight...

Two cell lines, M10-45-2 and L-41, were studied, each of which possessed specific resistance either to poliovirus or to coxsackievirus. Infection of M10-45-2 cells with poliovirus ribonucleic acid (RNA) and L-41 cells with infectious coxsackievirus RNA was accompanied by production of complete viruses in each of the resistant cell lines. During incubation of the cells with the virus to which th...

Several group A coxsackieviruses (A13, 15, 18, and 21), but not polioviruses or group B coxsackieviruses, are rapidly inactivated in low ionic strength solutions at neutral pH. The extent of inactivation is dependent upon temperature and molarity. Virions inactivated in this manner contain a normal complement of infectious RNA which remains in a state resistant to the action of ribonuclease. Ho...

Coxsackieviruses are important pathogens in children and the outcomes of neonatal infection can be serious or fatal. However, the outcomes of coxsackievirus infection during early gestation are not well defined. In this study, we examined the possibility of vertical transmission of coxsackievirus B3 (CVB3) and the effects of CVB3 infection on early pregnancy of ICR mice. We found that the coxsa...

Current advancement in electronic devices is so rapid that silicon, the semiconductor material most widely used today, needs to be replaced in some of the fields. Silicon carbide (SiC) is a wide band gap semiconductor satisfying requirements to replace silicon in devices operating at high power and high frequency at elevated temperature, and in harsh environments. Hexagonal polytypes of SiC, su...

Replication of picornaviral genomes requires recognition of at least three cis-acting replication elements: oriL, oriI, and oriR. Although these elements lack an obvious consensus sequence or structure, they are all recognized by the virus-encoded 3C protein. We have studied the poliovirus 3C-oriI interaction in order to begin to decipher the code of RNA recognition by picornaviral 3C proteins....

Previous studies have suggested that enterovirus infections during pregnancy may increase the risk of type 1 diabetes in the offspring. Our aim was to evaluate the role of first trimester enterovirus infections in a larger cohort of pregnant women. Two series of pregnant women were analyzed as follows: 948 women (series 1) and 680 women (series 2) whose child developed clinical diabetes before ...

INTRODUCTION Kawasaki disease (KD) most commonly develops in infants, although its specific cause is still unclear. We report here a rare case of adult-onset KD which revealed to be concurrently infected by Coxsackievirus A4. CASE PRESENTATION The patient was a 37-year-old Japanese man who presented with fever, exanthema, changes in the peripheral extremities, bilateral non-exudative conjunct...
