Streptococcus agalactiae also known as Group B Streptococcus (GBS) is a Gram-positive streptococcus responsible for the leading cause of neonatal meningitis, sepsis, and pneumonia in newborn babies and also cause serious infections in adults who are immunocompromised. They can also colonize human skin and mucous membranes without causing any symptoms associated with infection. Streptococcus agalactiae 2603V/R is a serotype V clinical isolate which is the most common serotype associated with GBS-infected non-pregnant adults.
Streptococcus agalactiae 2603V/R has a genome of approximately 2.16 Mb encoding about 2200 proteins and a GC content of 35.6%. The key publication reporting this work is by Tettelin et al. "Complete genome sequence and comparative genomic analysis of an emerging human pathogen, serotype V Streptococcus agalactiae". Proc Natl Acad Sci USA 2002, 99(19):12391-12396. Streptococcus agalactiae 2603V/R was sequenced by The Institute for Genomic Research (TIGR) and funded by NIAID. The core information for the database is a table of 2177 predicted open reading frams (ORFs). Each gene record is identified by a gene id, for example: SAG0001 to SAG2175. Record designations have some discontinuities and some IDs have number suffix of 1, 2, 3 etc. We did not annotate this genome but use it as one of the organisms for comparative genomic analysis of oral streptococci.
Basic summaries of specific information are available below in the
Predefined Database Searches which contain links to the complete gene record.
For a general perspective of the genome, we recommend you go to the Gene Image Map
and browse blocks of coordinates. Caution: The entire 2.16 Mb genome can be viewed at
one time, however this large file can cause some machines to freeze. Browsing and searching
are also facilitated by the [Functional Classes], [EC Table], and [Biochemical Pathways]
summaries. For precise inquiries on the other hand, start with the search capabilities
and their associated tables. Please note that some analyses are not yet available and we removed links to these pages. We encourage anyone with questions or
