Parasite Genome Blast Server

The server currently allows the user to perform blast searches on 14 different nucleotide databases for a range of organisms. The full list of databases with a brief explanation is as follows :-

  • Brugia malayi DNA - species specific nucleotide database (containing 7362 sequences and 2,677,070 nucleotides, created 27/03/97)

  • Onchocerca volvulus DNA - species specific nucleotide database (611 seq., 262,230 nt., 27/03/97)

  • Filarial nematode DNA - nucleotide database with sequences from all filarial nematodes (including both Brugia malayi and Onchocerca volvulus) (8212 seq., 3,102,504 nt., 27/03/97)

  • African trypanosome DNA - nucleotide database containing sequences from all species of African trypanosome (4262 seq., 2,313,906 nt., 27/03/97)

  • Trypanosoma cruzi DNA - species specific nucleotide database (398 seq., 442,391 nt., 27/03/97)

  • Leishmania major DNA - species specific nucleotide database (626 seq., 323,883 nt., 27/03/97)

  • Leishmania spp. DNA - nucleotide database containing sequences from all Leishmania species (including Leishmania major) (1,057 seq., 877,509 nt., 27/03/97)

  • kinetoplastid protozoan DNA - nucleotide database containing sequences from all Leishmania, Trypanosoma and Crithidia species (5994 seq., 3,851,441 nt., 27/03/97)

  • Schistosoma mansoni DNA - species specific nucleotide database (2621 seq., 963,118 nt., 27/03/97)

  • Schistosoma spp. DNA - nucleotide database containing sequences from all Schistosoma species (including Schistosoma mansoni) (2989 seq., 1,138,429 nt., 27/03/97)

  • Toxoplasma gondii DNA - species specific nucleotide database (8458 seq., 3,084,945 nt., 27/03/97)

  • Plasmodium falciparum DNA - species specific nucleotide database (2880 seq., 1,935,530 nt., 27/03/97)

  • Plasmodium spp. DNA - nucleotide database containing sequences from all Plasmodium species (including Plasmodium falciparum) (3253 seq., 2,476,458 nt., 27/03/97)

  • Apicomplexa DNA - nucleotide database containing sequences from all Apicomplexa species (12,144 seq., 5,987,828 nt., 27/03/97)

    • It should be noted that no new data can be gained by searching a species specific database following a search of a more general database containing that data.

    NOTE The blast databases are now available to download for local use via the parasite genome ftp site.

    The blast search programs used are as follows :-

    blastn
    compares a nucleotide query sequence against a nucleotide sequence database

    tblastn
    compares a protein query sequence against a nucleotide sequence database dynamically translated in all reading frames

    tblastx
    compares the six-frame translations of a nucleotide query sequence against the six-frame translations of a nucleotide sequence database.
