We describe a procedure for the isolation of virus particles from the marine brown alga Ectocarpus siliculosus. Virus particles are composed of at least 13 different polypeptides, including two glycoproteins, and double-stranded DNA. A typical virus DNA preparation contains three fractions, namely linear DNA and circular DNA, each composed of about...

The double-stranded DNA genome of the Ectocarpus siliculosus virus, EsV, is interrupted by numerous single-stranded gaps. We have investigated whether single-stranded regions occur at random or at specific sites. A brief treatment with a single-strand-specific endonuclease dissected the genome into two large fragments, but more extensive treatment...

Ectocarpus siliculosus virus, EsV, multiplies in sporangia and gametangia of the marine brown alga Ectocarpus siliculosus. We describe an improved method for the isolation of morphologically intact and infectious virus from diseased plants. We show that treatment of virus particles with high concentrations of CsCl results in a substantial loss of s...

Laboratory cultures of Ectocarpus siliculosus originating from New Zealand showed a defect in gametangium formation. Nuclear divisions in gametangium initials are not followed by cell wall formation. In the resulting multinucleate cells nuclear DNA increases dramatically, and nuclear membranes disintegrate. Eventually, the entire structure is fille...

In diesem Beitrag wird die Faktenlage und die deutsche Rechtsprechung zum Masern-Virus und zur Virologie generell dargestellt. Das Urteil des Oberlandesgericht Stuttgart im Masern-Virus-Prozess, mit dem ich den Prozess gewonnen habe, Aktenzeichen 12 U 63/1 vom 16.2.2016, wurde durch den Bundesgerichtshof in Karlsruhe am 1.12.2016 bestätigt (Aktenz...
