Welcome to the Brucella Bioinformatics Portal (BBP)!

Brucella is a Gram-negative, facultative intracellular coccobacillus which causes zoonotic brucellosis in humans and a variety of animal species. Brucellosis is one of the most common zoonotic diseases worldwide. Brucellosis is also re-emerging zoonosis. As described by Pappas et al, "human brucellosis remains the commonest zoonotic disease worldwide with more than 500 000 new cases annually".

The Brucellae are taxonomically placed in the alpha-2 subdivision of the class Proteobacteria. Traditionally there are six species of Brucella based on the preferential host specificity: B. melitensis (goats), B. abortus (cattle), B. suis (swine), B. canis (dogs), B. ovis (sheep) and B. neotomae (desert mice); two new species B. cetaceae (cetacean) and B. pinnipediae (seal) have recently been described by Cloeckaert et al. [Microbes Infect (2001) 3, 729-738]. The first four species are pathogenic to humans in decreasing order of severity making brucellosis a zoonotic disease. These Brucella species have been identified as priority agents amenable for use in biological warfare and bio-terrorism and listed as NIAID category B priority pathogens. Complete genome sequences of 25 Brucella strains are now available. A Brucella genome usually has two circular chromosomes of approximately 2.1 MB and 1.2 MB and has a GC content of approximately 57%. There are approximately 3,200 - 3,400 ORFs in each genome. The DNA sequences among different Brucella spp. share greater than 90% homology. The Brucella taxonomy is available here from the NCBI Taxonomy database and is also overseen by the Brucella Taxonomy Committee.

This BBP website is dedicated to becoming a bioinformatics resource portal for the Brucella research community to facilitate Brucella reearch. BBP has long been developed by Dr. He and used as a model for the overall PHIDIAS development. BBP includes a list of programs for analysis of Brucella and host-Brucella interactions:

  • Genomic Sequence Analysis:
  • Brucella Genome Analysis: Detailed analysis and download of the Brucella genome, gene, protein and sequence data.
  • Protein Domains in Brucella: This program searches Brucella -specific protein domains. As an integrated part of Pacodom, this program can also be used to search and compare protein domains of other pathogens.

  • PHI Specific Curation:
  • General Brucellosis Information: General information about Brucella and brucellosis as part of Phinfo. Please click here for advanced topic search of Brucella and brucellosis.
  • Brucella Gene Query: This program searches Brucella and host genes. This is part of Phigen that also be used to compare with other pathogen genes.
  • Brucella Virulence Factors: A collection of Brucella virulence factors.
  • Host-Brucella Interaction Network: this program analyze networks involving the interactions between Brucella and hosts. It is part of Phinet that also targets for many other pathogens.
  • Brucella as a Hazard: This program focuses on Brucella-related safety and administrative issues. It is part of HazARD that is also able to compare safety and administrative issues between Brucella and other pathogens.

  • Brucella-specific Gene Expression:
  • Phix: PHI Gene Expression Database.
  • MacroPath: Macrophage-Brucella Interaction.

  • Brucella-specific literature:
  • LiteSearch: Brucella literature search and mining programs.
  • Publications: Brucella-specific publications and links.
