English, FrenchLes bactéries qui appartiennent au groupe Streptococcus anginosus (streptocoques intermedius, constellatus et anginosus) peuvent causer de graves infections à pyogènes qui ont tendance à former des abcès. Le présent article contient un cas de pyomyosite du groupe S anginosus chez un homme de 47 ans. Le pathogène a été décelé récupéré dans une des deux cultures sanguines prélevées sur le patient, mais au départ, la spéciation n’a pas été effectuée parce que l’organisme était considéré comme un contaminant (groupe de streptocoques viridians). Le diagnostic a finalement été confirmé au moyen du séquençage de l’ADN ribosomal 16S du fluide purulent obtenu dans l’aspirat d’un abcès musculaire. Le présent cas fait ressortir le fait que la détection d’une seule culture sanguine positive dans un organisme appartenant au groupe S anginosus devrait susciter une évaluation attentive du patient afin de trouver un foyer d’infection à pyogènes. Il fait également ressortir l’utilité potentielle de l’amplification et du séquençage de l’ADN ribosomal 16S pour la détection directe d’un pathogène dans le fluide aspiré en cas de pyomyosite lorsque le traitement aux antibiotiques a commencé à être administré avant le prélèvement.

Phylogenomics and the dynamic genome evolution of the genus streptococcus.

Richards VP1, Palmer SR, Pavinski Bitar PD, Qin X, Weinstock GM, Highlander SK, Town CD, Burne RA, Stanhope MJ.Author information 1Department of Population Medicine and Diagnostic Sciences, College of Veterinary Medicine, Cornell University.AbstractThe genus Streptococcus comprises important pathogens that have a severe impact on human health and are responsible for substantial economic losses to agriculture. Here, we utilize 46 Streptococcus genome sequences (44 species), including eight species sequenced here, to provide the first genomic level insight into the evolutionary history and genetic basis underlying the functional diversity of all major groups of this genus. Gene gain/loss analysis revealed a dynamic pattern of genome evolution characterized by an initial period of gene gain followed by a period of loss, as the major groups within the genus diversified. This was followed by a period of genome expansion associated with the origins of the present extant species. The pattern is concordant with an emerging view that genomes evolve through a dynamic process of expansion and streamlining. A large proportion of the pan-genome has experienced lateral gene transfer (LGT) with causative factors, such as relatedness and shared environment, operating over different evolutionary scales. Multiple gene ontology terms were significantly enriched for each group, and mapping terms onto the phylogeny showed that those corresponding to genes born on branches leading to the major groups represented approximately one-fifth of those enriched. Furthermore, despite the extensive LGT, several biochemical characteristics have been retained since group formation, suggesting genomic cohesiveness through time, and that these characteristics may be fundamental to each group. For example, proteolysis: mitis group; urea metabolism: salivarius group; carbohydrate metabolism: pyogenic group; and transcription regulation: bovis group.
