The detection and sequencing of a broad-host-range conjugative IncP-1β plasmid in an epidemic strain of Mycobacterium abscessus subsp. bolletii.

Project description:BackgroundAn extended outbreak of mycobacterial surgical infections occurred in Brazil during 2004-2008. Most infections were caused by a single strain of Mycobacterium abscessus subsp. bolletii, which was characterized by a specific rpoB sequevar and two highly similar pulsed-field gel electrophoresis (PFGE) patterns differentiated by the presence of a ∼50 kb band. The nature of this band was investigated.Methodology/principal findingsGenomic sequencing of the prototype outbreak isolate INCQS 00594 using the SOLiD platform demonstrated the presence of a 56,267-bp [corrected] circular plasmid, designated pMAB01. Identity matrices, genetic distances and phylogeny analyses indicated that pMAB01 belongs to the broad-host-range plasmid subgroup IncP-1β and is highly related to BRA100, pJP4, pAKD33 and pB10. The presence of pMAB01-derived sequences in 41 M. abscessus subsp. bolletii isolates was evaluated using PCR, PFGE and Southern blot hybridization. Sixteen of the 41 isolates showed the presence of the plasmid. The plasmid was visualized as a ∼50-kb band using PFGE and Southern blot hybridization in 12 isolates. The remaining 25 isolates did not exhibit any evidence of this plasmid. The plasmid was successfully transferred to Escherichia coli by conjugation and transformation. Lateral transfer of pMAB01 to the high efficient plasmid transformation strain Mycobacterium smegmatis mc(2)155 could not be demonstrated.Conclusions/significanceThe occurrence of a broad-host-range IncP-1β plasmid in mycobacteria is reported for the first time. Thus, genetic exchange could result in the emergence of specific strains that might be better adapted to cause human disease.

Complete Genome Sequence of Mycobacterium abscessus subsp. bolletii.

Project description:We report the complete genome sequence of a Mycobacterium abscessus subsp. bolletii isolate recovered from a sputum culture from an individual with cystic fibrosis. This sequence is the first completed whole-genome sequence of M. abscessus subsp. bolletii and adds value to studies of M. abscessus complex genomics.

Phylogenomics of Brazilian epidemic isolates of Mycobacterium abscessus subsp. bolletii reveals relationships of global outbreak strains.

Project description:Rapidly growing, non-tuberculous mycobacteria (NTM) in the Mycobacterium abscessus (MAB) species are emerging pathogens that cause various diseases including skin and respiratory infections. The species has undergone recent taxonomic nomenclature refinement, and is currently recognized as two subspecies, M. abscessus subsp. abscessus (MAB-A) and M. abscessus subsp. bolletii (MAB-B). The recently reported outbreaks of MAB-B in surgical patients in Brazil from 2004 to 2009 and in cystic fibrosis patients in the United Kingdom (UK) in 2006 to 2012 underscore the need to investigate the genetic diversity of clinical MAB strains. To this end, we sequenced the genomes of two Brazilian MAB-B epidemic isolates (CRM-0019 and CRM-0020) derived from an outbreak of skin infections in Rio de Janeiro, two unrelated MAB strains from patients with pulmonary infections in the United States (US) (NJH8 and NJH11) and one type MAB-B strain (CCUG 48898) and compared them to 25 publically available genomes of globally diverse MAB strains. Genome-wide analyses of 27,598 core genome single nucleotide polymorphisms (SNPs) revealed that the two Brazilian derived CRM strains are nearly indistinguishable from one another and are more closely related to UK outbreak isolates infecting CF patients than to strains from the US, Malaysia or France. Comparative genomic analyses of six closely related outbreak strains revealed geographic-specific large-scale insertion/deletion variation that corresponds to bacteriophage insertions and recombination hotspots. Our study integrates new genome sequence data with existing genomic information to explore the global diversity of infectious M. abscessus isolates and to compare clinically relevant outbreak strains from different continents.

Genome Sequence of an Epidemic Isolate of Mycobacterium abscessus subsp. bolletii from Rio de Janeiro, Brazil.

Project description:Multiple isolates of Mycobacterium abscessus subsp. bolletii, collectively called BRA100, were associated with outbreaks of postsurgical skin infections across various regions of Brazil from 2003 to 2009. We announce the draft genome sequence of a newly sequenced BRA100 strain, M. abscessus subsp. bolletii CRM-0020, isolated from a patient in Rio de Janeiro, Brazil.

Draft Genome Sequence of Mycobacterium abscessus subsp. bolletii INCQS 00594.

Project description:An epidemic of surgical-site infections by a single strain of Mycobacterium abscessus subsp. bolletii affected >1,700 patients in Brazil from 2004 to 2008. The genome of the epidemic prototype strain M. abscessus subsp. bolletii INCQS 00594, deposited in the collection of the National Institute for Health Quality Control (INCQS), was sequenced.

The first structure of a mycobacteriophage, the Mycobacterium abscessus subsp. bolletii phage Araucaria.

Project description:The unique characteristics of the waxy mycobacterial cell wall raise questions about specific structural features of their bacteriophages. No structure of any mycobacteriophage is available, although ∼3,500 have been described to date. To fill this gap, we embarked in a genomic and structural study of a bacteriophage from Mycobacterium abscessus subsp. bolletii, a member of the Mycobacterium abscessus group. This opportunistic pathogen is responsible for respiratory tract infections in patients with lung disorders, particularly cystic fibrosis. M. abscessus subsp. bolletii was isolated from respiratory tract specimens, and bacteriophages were observed in the cultures. We report here the genome annotation and characterization of the M. abscessus subsp. bolletii prophage Araucaria, as well as the first single-particle electron microscopy reconstruction of the whole virion. Araucaria belongs to Siphoviridae and possesses a 64-kb genome containing 89 open reading frames (ORFs), among which 27 could be annotated with certainty. Although its capsid and connector share close similarity with those of several phages from Gram-negative (Gram(-)) or Gram(+) bacteria, its most distinctive characteristic is the helical tail decorated by radial spikes, possibly host adhesion devices, according to which the phage name was chosen. Its host adsorption device, at the tail tip, assembles features observed in phages binding to protein receptors, such as phage SPP1. All together, these results suggest that Araucaria may infect its mycobacterial host using a mechanism involving adhesion to cell wall saccharides and protein, a feature that remains to be further explored.

Outbreaks due to Mycobacterium abscessus subsp. bolletii in southern Brazil: persistence of a single clone from 2007 to 2011.

Project description:Outbreaks associated with rapidly growing mycobacteria (RGM) have been increasingly reported worldwide, including in Brazil. Among the RGM, the Mycobacterium abscessus complex is the most pathogenic and related to multidrug resistance. The aim of this study was to evaluate the antimicrobial susceptibility and molecular profile of RGM isolates involved in new postsurgical infection outbreaks in Brazil since 2007. Of the 109 cases reported in the state of Rio Grande do Sul between 2007 and 2011, 43 (39 %) had confirmed mycobacterial growth in culture. Clinical isolates were obtained from biopsy specimens or abscess aspirates. PRA-hsp65 restriction pattern identified the isolates as M. abscessus type 2, and partial rpoB sequencing confirmed the identification as M. abscessus subsp. bolletii. All isolates were susceptible to amikacin and resistant to ciprofloxacin, doxycycline, sulfamethoxazole, moxifloxacin and tobramycin. Most isolates (72 %) were fully susceptible to cefoxitin but six isolates (14 %) were fully resistant to clarithromycin. The latter differed from the susceptibility profiles of the previously described BRA100 clone from other Brazilian regions. Nevertheless, pulsed-field gel electrophoresis analysis revealed that these isolates belonged to a single BRA100 clone. In conclusion, our study reports the persistence of an emergent single and highly resistant clone of M. abscessus subsp. bolletii for several years even after national implementation of infection control measures.
