We recently described the presence of 3 pilus variants in the human pathogen group B streptococcus (GBS; also known as Streptococcus agalactiae), each encoded by a distinct pathogenicity island, as well as the ability of pilus components to elicit protection in mice against homologous challenge. To determine whether a vaccine containing a combination of proteins from the 3 pilus types could pro...
MOTIVATION Lateral gene transfer is a major mechanism contributing to bacterial genome dynamics and pathovar emergence via pathogenicity island (PAI) spreading. However, since few of these genomic exchanges are experimentally reproducible, it is difficult to establish evolutionary scenarios for the successive PAI transmissions between bacterial genera. Methods initially developed at the gene an...
Streptomyces turgidiscabies Car8 is an actinobacterium that causes the economically important disease potato scab. Pathogenesis in this species is associated with a mobile pathogenicity island (PAISt) that site specifically inserts into the bacA gene in Streptomyces spp. Here we provide the 674,223 bp sequence of PAISt, which consists of two non-overlapping modules of 105,364 and 568,859 bp. Th...
Recent data indicate that the human pathogen group B Streptococcus (GBS) produces pilus-like structures encoded in genomic islands with similar organization to pathogenicity islands. On the basis of the amino acid sequence of their protein components, 3 different types of pili have been identified in GBS, at least 1 of which is present in all isolates. We recently demonstrated that recombinant ...
