“…Strain PHDC has been recovered from agricultural soil in the United States, including onion fields, and from people with CF in diverse locations in the United States and Europe, suggesting that this strain is widely distributed in the natural environment, which serves as a source of ongoing acquisition. 161,[298][299][300] Strains identical to those found in people with CF have also been isolated from onions and onion rot. 301,302 Furthermore, MLST analysis demonstrated that more than 20% of 381 CF isolates of Burkholderia were indistinguishable from strains recovered from the natural environment.…”

The 2013 Infection Prevention and Control (IP&C) Guideline for Cystic Fibrosis (CF) was commissioned by the CF Foundation as an update of the 2003 Infection Control Guideline for CF. During the past decade, new knowledge and new challenges provided the following rationale to develop updated IP&C strategies for this unique population:1. The need to integrate relevant recommendations from evidence-based guidelines published since 2003 into IP&C practices for CF. These included guidelines from the Centers for Disease Control and Prevention (CDC)/Healthcare Infection Control Practices Advisory Committee (HICPAC), the World Health Organization (WHO), and key professional societies, including the Infectious Diseases Society of America (IDSA) and the Society for Healthcare Epidemiology of America (SHEA). During the past decade, new evidence has led to a renewed emphasis on source containment of potential pathogens and the role played by the contaminated healthcare environment in the transmission of infectious agents. Furthermore, an increased understanding of the importance of the application of implementation science, monitoring adherence, and feedback principles has been shown to increase the effectiveness of IP&C guideline recommendations.2. Experience with emerging pathogens in the non-CF population has expanded our understanding of droplet transmission of respiratory pathogens and can inform IP&C strategies for CF. These pathogens include severe acute respiratory syndrome coronavirus and the 2009 influenza A H1N1. Lessons learned about preventing transmission of methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant gram-negative pathogens in non-CF patient populations also can inform IP&C strategies for CF.

“…A dendrogram was derived from the UPGMA linkage of correlation coefficients between the BOX-PCR fingerprint patterns from Bcc isolates. Data for reference strains were available from previous studies (Chen et al, 2001;Coenye et al, 2002Coenye et al, , 2004LiPuma et al, 2002) or were unpublished (J. J. LiPuma).…”

The taxonomic position of five recA gene clusters of Burkholderia cepacia complex (Bcc) isolates was determined using a polyphasic taxonomic approach, The levels of 16S rRNA and recA gene sequence similarity, multilocus sequence typing (MLST) data and the intermediate DNA-DNA binding values demonstrated that these five clusters represented five novel species within the Bcc. Biochemical identification of these species is difficult, as is the case for most Bcc species. However, identification of these novel species can be accomplished through recA gene sequence analysis, MLST and BOX-PCR profiling and by recA RFLP analysis. For diagnostic laboratories, recA gene sequence analysis offers the best combination of accuracy and simplicity. Based on these results, we propose five novel Bcc species, Burkholderia latens sp. nov. (type strain FIRENZE 3(T) =LMG 24064(T) =CCUG 54555(T)), Burkholderia diffusa sp. nov. (type strain AU1075(T) =LMG 24065(T) =CCUG 54558(T)), Burkholderia arboris sp. nov. (type strain ES0263A(T) =LMG 24066(T) =CCUG 54561(T)), Burkholderia seminalis sp. nov. (type strain AU0475(T) =LMG 24067(T) =CCUG 54564 (T)) and Burkholderia metallica sp. nov. (type strain AU0553(T) =LMG 24068(T) =CCUG 54567(T)). In the present study, we also demonstrate that Burkholderia ubonensis should be considered a member of the Bcc

“…For instance, the biocontrol strain B. ambifaria AMMD and clinical isolate B. ambifaria AU0212 are clonal (Payne et al, 2005). A B. cepacia genomovar III isolate recovered from agricultural soil in the midAtlantic region of the United States is indistinguishable from an isolate frequently recovered from CF patients of the same region using the fingerprinting method (LiPuma et al, 2002).…”

Phase variation has a role in Burkholderia ambifaria niche adaptation

Members of the Burkholderia cepacia complex (Bcc), such as B. ambifaria, are effective biocontrol strains, for instance, as plant growth-promoting bacteria; however, Bcc isolates can also cause severe respiratory infections in people suffering from cystic fibrosis (CF). No distinction is known between isolates from environmental and human origins, suggesting that the natural environment is a potential source of infectious Bcc species. While investigating the presence and role of phase variation in B. ambifaria HSJ1, an isolate recovered from a CF patient, we identified stable variants that arose spontaneously irrespective of the culture conditions. Phenotypic and proteomic approaches revealed that the transition from wild-type to variant types affects the expression of several putative virulence factors. By using four different infection models (Drosophila melanogaster, Galleria mellonella, macrophages and Dictyostelium discoideum), we showed that the wild-type was more virulent than the variant. It may be noted that the variant showed reduced replication in a human monocyte cell line when compared with the wild-type. On the other hand, the variant of isolate HSJ1 was more competitive in colonizing plant roots than the wild-type. Furthermore, we observed that only clinical B. ambifaria isolates generated phase variants, and that these variants showed the same phenotypes as observed with the HSJ1 variant. Finally, we determined that environmental B. ambifaria isolates showed traits that were characteristic of variants derived from clinical isolates. Our study therefore suggest that B. ambifaria uses phase variation to adapt to drastically different environments: the lung of patients with CF or the rhizosphere.
