| phylogenetic analysis of ljungan virus and a-2 plaque virus, new members of the picornaviridae. | in addition to the viruses belonging to the nine proposed genera of the picornaviridae, enterovirus, rhinovirus, cardiovirus, aphtovirus, hepatovirus, parechovirus, kobuvirus, erbovirus and teschovirus, two new members of this family have recently been discovered. three strains of ljungan virus (lv) were isolated from bank voles (clethrionomys glareolus) and a-2 plaque virus (a-2) was isolated from human sera. to study the genetic relationship between these recently discovered viruses and the me ... | 2002 | 11955639 |
| induction of hepatitis b antibody in experimental animals by immunization with a-2 plaque virus. | a sero-conversion for hepatitis b antibody has resulted from immunization of patas monkeys, guinea pigs, and rabbits with the a-2 plaque virus. this agent was isolated in tissue culture from patient sera that were positive for hepatitis b antigen. the immune response was assayed with techniques of direct and indirect counter-immunoelectrophoresis, and immune electron microscopy. | 1973 | 4128387 |
