The invasive Neisseria meningitidis MenC CC103 from Brazil is characterized by an accessory gene repertoire.

Neisseria meningitidis infections are a major issue for global health. The invasive MenC ST-103 clonal complex (CC103) has been the most prevalent in meningococcal outbreaks in Brazil, occurring also in several countries worldwide. Here we have analysed the population structure and accessory genome of MenC CC103 strains from a global perspective.

The mitogenome of Onchocerca volvulus from the Brazilian Amazonia focus.

We report here the first complete mitochondria genome of Onchocerca volvulus from a focus outside of Africa. An O. volvulus mitogenome from the Brazilian Amazonia focus was obtained using a combination of high-throughput and Sanger sequencing technologies.

Genomic analysis of a nontoxigenic, invasive Corynebacterium diphtheriae strain from Brazil.

We report the complete genome sequence and analysis of an invasive Corynebacterium diphtheriae strain that caused endocarditis in Rio de Janeiro, Brazil. It was selected for sequencing on the basis of the current relevance of nontoxigenic strains for public health. The genomic information was explored in the context of diversity, plasticity and genetic relatedness with other contemporary strains.

Full characterization of the integrative and conjugative element carrying the metallo-β-lactamase bla SPM-1 and bicyclomycin bcr1 resistance genes found in the pandemic Pseudomonas aeruginosa clone SP/ST277.

Objectives: This study aimed to characterize the genomic context of the bla SPM-1 gene in Brazilian strains belonging to the pandemic Pseudomonas aeruginosa clone SP/ST277.

Methods: WGS of clone SP/ST277 strains was performed using a Nextera paired-end library in an Illumina HiSeq 2500 sequencer. bla SPM-1 context was assessed by de novo assembly and gene prediction and annotation tools.
