Corynebacterium pseudotuberculosis is an intracellular pathogen that causes Caseous lymphadenitis (CLA) disease in sheep and goats. The widespread occurrence and the economic importance of this pathogen have prompted investigation of its pathogenesis. We used a genomic library of C. pseudotuberculosis to generate 1440 genomic survey sequences (GSSs); these(More)
BACKGROUND Corynebacterium pseudotuberculosis, a gram-positive, facultative intracellular pathogen, is the etiologic agent of the disease known as caseous lymphadenitis (CL). CL mainly affects small ruminants, such as goats and sheep; it also causes infections in humans, though rarely. This species is distributed worldwide, but it has the most serious(More)
Caseous lymphadenitis is a chronic goat and sheep disease caused by Corynebacterium pseudotuberculosis (Cp) that accounts for a huge economic loss worldwide. Proper vaccination or medication is not available because of the lack of understanding of molecular biology of the pathogen. In a recent approach, four Cp (CpFrc41, Cp1002, CpC231, and CpI-19) genomes(More)
BACKGROUND Corynebacterium pseudotuberculosis is generally regarded as an important animal pathogen that rarely infects humans. Clinical strains are occasionally recovered from human cases of lymphadenitis, such as C. pseudotuberculosis FRC41 that was isolated from the inguinal lymph node of a 12-year-old girl with necrotizing lymphadenitis. To detect(More)
Due to the advent of the so-called Next-Generation Sequencing (NGS) technologies the amount of monetary and temporal resources for whole-genome sequencing has been reduced by several orders of magnitude. Sequence reads can be assembled either by anchoring them directly onto an available reference genome (classical reference assembly), or can be concatenated(More)
This work reports the completion and annotation of the genome sequence of Corynebacterium pseudotuberculosis I19, isolated from an Israeli dairy cow with severe clinical mastitis. To present the whole-genome sequence, a de novo assembly approach using 33 million short (25-bp) mate-paired SOLiD reads only was applied. Furthermore, the automatic, functional,(More)
This review covers all Brazilian Genome, EST and Metagenome Projects, Sequencing Networks' history and structure, and patents related to Brazilian Genome Projects, beginning with the first genome sequenced in this country, i.e. the 9a5c strain of Xylella fastidiosa CVC, up till the recently sequenced 1002 strain of Corynebacterium pseudotuberculosis, which(More)
Corynebacterium pseudotuberculosis, a Gram-positive intracellular pathogen, is the etiological agent of caseous lymphadenitis or CLA. This bacterium infects goats and sheep and causes great economic losses worldwide annually, mainly for goat producers. Despite its importance, CLA is still poorly characterized. However, with advances in the genomic field,(More)
