Abstract
An outbreak of bloodstream infection (BSI) caused by members of the Burkholderia cepacia complex (Bcc) took place from March 2012 until April 2014 involving thirteen patients. AIM To describe an outbreak investigation of BSI Bcc and showing how genetic sequencing tools contributed to confirm the hypothesis of extrinsic contamination proposed by an observational study. METHODS The Infection Control Department revised and reinforced good practices of infusion therapy and catheter care, visits to affected wards, a case control study, and environmental screening based on the case-control findings. RESULTS Data from the case-control study found an association of cases with central venous catheter (OR 1.36; CI 1.15-1.67) and intravenous cisatracurium use (OR 10.75; CI 1.67-68.89). Visits to the operatory block revealed problems related to the cold chain used for the preservation of thermolabile cisatracurium. We could not retrieve Bcc from environmental samples using classic microbiology. New samples from the same surfaces were obtained for genetic sequencing. Bcc was identified in the cooler box, refrigerator and reusable ice packages. CONCLUSION Environmental screening using genetic sequencing proved to be a useful tool for confirming our hypothesis of extrinsic contamination raised by the case-control study.

Abstract
A nosocomial polyclonal outbreak associated to bacteremia caused by different Burkholderia cepacia complex (BCC) species and clones is reported. Molecular characterization identified Burkholderia stabilis, Burkholderia contaminans, and Burkholderia ambifaria among BCC isolates obtained from patients in neonatal and adult intensive care units. BCC was also isolated from an intrinsically contaminated ultrasound gel, which constituted the presumptive BCC source. Prior BCC outbreak related to contaminated ultrasound gels have been described in the setting of transrectal prostate biopsy. Outbreak caused strains and/or clones of BCC have been reported, probably because BCC are commonly found in the natural environment; most BCC species are biofilm producers, and different species may contaminate an environmental source. The finding of multiple species or clones during the analysis of nosocomial BCC cases might not be enough to reject an outbreak from a common source.

Abstract
Aim: The objective was to describe an outbreak of bloodstream infections
by Burkholderia cepacia complex (Bcc) in bone marrow transplant and
hematology outpatients. Methods: On February 15, 2008 a Bcc outbreak was suspected. 24 cases
were identified. Demographic and clinical data were evaluated. Environment and
healthcare workers' (HCW) hands were cultured. Species were determined and typed.
Reinforcement of hand hygiene, central venous catheter (CVC) care, infusion therapy,
and maintenance of laminar flow cabinet were undertaken. 16 different HCWs had cared
for the CVCs. Multi-dose heparin and saline were prepared on counter common to both
units. Findings: 14 patients had B. multivorans (one patient
had also B. cenopacia), six non-multivorans Bcc and
one did not belong to Bcc. Clone A B. multivorans occurred in 12
patients (from Hematology); in 10 their CVC had been used on February 11/12.
Environmental and HCW cultures were negative. All patients were treated with
meropenem, and ceftazidime lock-therapy. Eight patients (30%) were hospitalized. No
deaths occurred. After control measures (multidose vial for single patient; CVC lock
with ceftazidime; cleaning of laminar flow cabinet; hand hygiene improvement; use of
cabinet to store prepared medication), no new cases occurred. Conclusions: This polyclonal outbreak may be explained by a common
source containing multiple species of Bcc, maybe the laminar flow cabinet common to
both units. There may have been contamination by B. multivorans
(clone A) of multi-dose vials.

Abstract
The application of proteomics to translational and clinical microbiology is one of the most advanced frontiers in the management and control of infectious diseases and in the understanding of complex microbial systems within human fluids and districts. This new approach aims at providing, by dedicated bioinformatic pipelines, a thorough description of pathogen proteomes and their interactions within the context of human host ecosystems, revolutionizing the vision of infectious diseases in biomedicine and approaching new viewpoints in both diagnostic and clinical management of the patient. Indeed, in the last few years, many laboratories have matured a series of advanced proteomic applications, aiming at providing individual proteome charts of pathogens, with respect to their morph and/or cell life stages, antimicrobial or antimycotic resistance profiling, epidemiological dispersion. Herein, we aim at reviewing the current state-of-the-art on proteomic protocols designed and set-up for translational and diagnostic microbiological purposes, from axenic pathogens' characterization to microbiota ecosystems' full description. The final goal is to describe applications of the most common MALDI-TOF MS platforms to advanced diagnostic issues related to emerging infections, increasing of fastidious bacteria, and generation of patient-tailored phylotypes. This article is part of a Special Issue entitled: Trends in Microbial Proteomics.

Abstract
The aim of this study was to establish the identification ability of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) for bacteria of Burkholderia cepacia complex (Bcc) and to compare these results with those obtained by a molecular method (PCR-RFLP). A total of 57 isolates was used in the study. Isolates were collected from 31 patients attending the Regional Cystic Fibrosis Unit from January 2001 to December 2005. For phenotypic identification, both automated and manual systems were used. Using mass spectrometry, we identified all 57 isolates, previously identified by molecular method. Of these, 28 isolates were identified as B. cenocepacia, although not differentiated further into lineages. Moreover, other isolates were identified as B. cepacia (12 isolates), B. stabilis (12 isolates), and B. vietnamiensis (5 isolates). Our data indicate a good correlation between the two approaches.

Abstract
Background Burkholderia cepacia is a Gram-negative pathogen that causes serious respiratory infections in immunocompromised patients and individuals with cystic fibrosis. This bacterium is known to release extracellular proteins that may be involved in virulence. Methodology/Principal Findings In the present study, B. cepacia grown to mid-logarithmic and early-stationary phases were investigated on their ability to invade and survive intracellularly in A549 lung epithelial cells in order to discern the fate of these bacteria in the pathogenesis of B. cepacia lung infections in in vitro condition. The early-stationary phase B. cepacia was demonstrated to be more invasive than mid-logarithmic phase. In addition, culture supernatants of B. cepacia obtained from these phases of growth were also demonstrated to cause different cytotoxic potency on the A549 human lung epithelial cells. Profiling of the supernatants using the gel-based proteomics approach identified 43 proteins that were commonly released in both the growth phases and 40 proteins newly-released at the early-stationary phase. The latter proteins may account for the higher cytotoxic activity of the early-stationary culture supernatant compared to that obtained at the mid-logarithmic phase. Among the newly-released proteins in the early-stationary phase supernatant were flagellar hook-associated domain protein (FliD), flagellar hook-associated protein (FlgK), TonB-dependent siderophore (Fiu), Elongation factor G (FusA), phosphoglycerate kinase (Pgk) and sulfatase (AslA) which are known for their virulence. Conclusion/Significance Differences in the ability of B. cepacia to invade and survive intracellularly inside the epithelial cells at different phases of growth may improve our understanding of the varied disease progressions associated with B. cepacia infections. In addition, the identified culture supernatant proteins may be used as targets for the development of new strategies to control B. cepacia infection using agents that can block their release.
