International audience ; Brevundimonas diminuta is rarely described in clinical specimens, never at the umbilical stump. Most of the reported cases are in patients with underlying pathologies. We must integrate this microorganism in the etiological agents of nosocomial infections, but much remains to be understood about its virulence. We present a case of umbilical stump infection (omphalitis) caused by B. diminuta, in a preterm and hypotrophic new-born and discuss the diagnosis of this bacterium and its role as responsible of nosocomial neonatal infections.

International audience ; In this paper, we describe the first complete genome sequence of Providencia vermicola species, a clinical multidrug-resistant strain harboring the New Delhi Metallo-β-lactamase-1 (NDM-1) gene, isolated at the Kinshasa University Teaching Hospital, in Democratic Republic of the Congo. Whole genome sequencing of an imipenem-resistant clinical Gram-negative P. vermicola P8538 isolate was performed using MiSeq and Gridion, and then complete genome analysis, plasmid search, resistome analysis, and comparative genomics were performed. Genome assembly resulted in a circular chromosome sequence of 4,280,811-bp and 40.80% GC and a circular plasmid (pPV8538_NDM-1) of 151,684-bp and 51.93%GC, which was identified in an Escherichia coli P8540 strain isolated in the same hospital. Interestingly, comparative genomic analysis revealed multiple sequences acquisition within the P. vermicola P8538 chromosome, including three complete prophages, a siderophore biosynthesis NRPS cluster, a Type VI secretion system (T6SS), a urease gene cluster, and a complete Type-I-F CRISPR-Cas3 system. Β-lactamase genes, including blaCMY-6 and blaNDM-1, were found on the recombinant plasmid pPV8538_NDM-1, in addition to other antibiotic resistance genes such as rmtC, aac6'-Ib3, aacA4, catA1, sul1, aac6'-Ib-cr, tetA, and tetB. Genome comparison with Providencia species revealed 82.95% of average nucleotide identity (ANI), with P. stuartii species exhibiting 90.79% of proteome similarity. We report the first complete genome of P. vermicola species and for the first time the presence of the blaNDM-1 gene in this species. This work highlights the need to improve surveillance and clinical practices in DR Congo in order to reduce or prevent the spread of such resistance.
