Inconveniences of Memory. The Monument to the Soviet Army and Georgi Dimitrov’s Mausoleum in Sofia after 1989

The paper discusses the transformations of memory caused by the preservation, removal or redefinition of memorials. These transformations indicate the competition between political and ideological views in Bulgarian society after 1989. Two cases are analysed: the deconstruction of Georgi Dimitrov’s already-empty mausoleum in 1999 and the Monument to the Soviet Army, still standing in Sofia. Both instances are significant indicators of power constellations, which, in the second case, also have a precise foreign policy dimension (relations with Russia). The periodically activated debates, especially concerning the Monument to the Soviet Army, indicate the absence of a coherent memory policy and general ambiguous attitudes in Bulgarian society towards the communist past

Genomic analysis reveals the molecular basis for capsule loss in the group B Streptococcus population

The human and bovine bacterial pathogen Streptococcus agalactiae (Group B Streptococcus, GBS) expresses a thick polysaccharide capsule that constitutes a major virulence factor and vaccine target. GBS can be classified into ten distinct serotypes differing in the chemical composition of their capsular polysaccharide. However, non-typeable strains that do not react with anti-capsular sera are frequently isolated from colonized and infected humans and cattle. To gain a comprehensive insight into the molecular basis for the loss of capsule expression in GBS, a collection of well-characterized non-typeable strains was investigated by genome sequencing. Genome based phylogenetic analysis extended to a wide population of sequenced strains confirmed the recently observed high clonality among GBS lineages mainly containing human strains, and revealed a much higher degree of diversity in the bovine population. Remarkably, non-typeable strains were equally distributed in all lineages. A number of distinct mutations in the cps operon were identified that were apparently responsible for inactivation of capsule synthesis. The most frequent genetic alterations were point mutations leading to stop codons in the cps genes, and the main target was found to be cpsE encoding the portal glycosyl trasferase of capsule biosynthesis. Complementation of strains carrying missense mutations in cpsE with a wild-type gene restored capsule expression allowing the identification of amino acid residues essential for enzyme activity
