The Actinobacteria, Corynebacterium pseudotuberculosis strain P54B96, a nonmotile, non sporulating and a mesophile bacterium, was isolated from liver, lung and mediastinal lymph node lesions in an antelope from South Africa. This strain is interesting in the sense that it has been found together with non-tuberculous mycobacteria (NTMs) which could nevertheless play a role in the lesion formation. In this work, we describe a set of features of C. pseudotuberculosis P54B96, together with the details of the complete genome sequence and annotation. The genome comprises of 2.34 Mbp long, single circular genome with 2,084 protein-coding genes, 12 rRNA, 49 tRNA and 62 pseudogenes and a G+C content of 52.19%. The analysis of the genome se quence provides means to better understanding the molecular and genetic basis of virulence of this bacterium, enabling a detailed investigation of its pathogenesis.

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, and manual annotations were attained with the use of several algorithms in a multistep process.

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 economic impact in Oceania, Africa and South America. Although C. pseudotuberculosis causes major health and productivity problems for livestock, little is known about the molecular basis of its pathogenicity.

PIPS: Pathogenicity Island Prediction Software
(Public Library of Science, 2012-02) SOARES, Siomar de Castro; ABREU, Vinicius Augusto Carvalho de; RAMOS, Rommel Thiago Juca; CERDEIRA, Louise Teixeira; SILVA, Artur Luiz da Costa da; BAUMBACH, Jan; TROST, Eva; TAUCH, Andreas; HIRATA JÚNIOR, Raphael; GUARALDI, Ana Luiza de Mattos; MIYOSHI, Anderson; AZEVEDO, Vasco Ariston de Carvalho
The adaptability of pathogenic bacteria to hosts is influenced by the genomic plasticity of the bacteria, which can be increased by such mechanisms as horizontal gene transfer. Pathogenicity islands play a major role in this type of gene transfer because they are large, horizontally acquired regions that harbor clusters of virulence genes that mediate the adhesion, colonization, invasion, immune system evasion, and toxigenic properties of the acceptor organism. Currently, pathogenicity islands are mainly identified in silico based on various characteristic features: (1) deviations in codon usage, G+C content or dinucleotide frequency and (2) insertion sequences and/or tRNA genetic flanking regions together with transposase coding genes. Several computational techniques for identifying pathogenicity islands exist. However, most of these techniques are only directed at the detection of horizontally transferred genes and/or the absence of certain genomic regions of the pathogenic bacterium in closely related non-pathogenic species. Here, we present a novel software suite designed for the prediction of pathogenicity islands (pathogenicity island prediction software, or PIPS). In contrast to other existing tools, our approach is capable of utilizing multiple features for pathogenicity island detection in an integrative manner. We show that PIPS provides better accuracy than other available software packages. As an example, we used PIPS to study the veterinary pathogen Corynebacterium pseudotuberculosis, in which we identified seven putative pathogenicity islands.

Reannotation of the Corynebacterium diphtheriae NCTC13129 genome as a new approach to studying gene targets connected to virulence and pathogenicity in diphtheria

Background: The reannotation of genomes already on file is a new approach to discovering new genetic elements and to make the genomes more descriptive and current with relevant features regarding the organism’s lifestyle. Within this approach, the present study aimed to reannotate the genome of the Gram-positive human pathogen Corynebacterium diphtheriae, which causes diphtheria. The deposit of massive amounts of information linked to other spe cies of the genus Corynebacterium has facilitated the updating of the genomic interpretation of this microorganism. Additionally, the emergence of invasive disease by nontoxigenic strains of C. diphtheriae and the reemergence of diphtheria in partially immunized populations have given impetus to new studies in relation to its structural and functional genome. Results: In relation to structural genomics, 23 coding regions (coding sequences) were deleted and 71 new genes were added to the genome annotation. Nevertheless, all the pseudogenes were validated and ten new pseudogenes were created. In relation to functional genomics, about 57% of the genome annotation was updated and became functionally more informative. The product descriptions of 41% (973 proteins) were updated. Among them, 370 that were previously annotated as “hypothetical proteins,” now have more informative descriptions. With the new annotation, the plasticity of the genome became evident, which shows improvements in the annotation of 13 pathogenicity islands already described in the literature. In addition, the large number of transposases and the presence of structural genes of bacteriophages make their genomic versatility evident. Contrasting with this reality, it also allowed the clarification of some aspects concerned with mechanisms used by C. diphtheriae to stop the invasion of the genome by bacteriophages, mediated by the clustered regularly interspaced short palindromic repeats region. Conclusion: The reannotation of the C. diphtheriae genome provided an improvement in annotation of the C. diphtheriae genome in several aspects, such as virulence characteristics and plasticity events. Moreover, the protocol used here can be extended to various other pathogens in order to improve the genomic information already on file in public databases and to minimize propagating errors.
