Culture-based and non-growth-dependent detection of the Burkholderia cepacia complex in soil environments.
Burkholderia cepacia complex (Bcc) bacteria reside in soil, plant rhizospheres, and water, but their prevalence and distribution in outdoor environments is not clear. We sampled a variety of soil and rhizosphere environments with which people may have contact: playgrounds, athletic fields, parks, hiking trails, residential yards, and gardens. A total of 91 sites was sampled in three large U.S. ...
متن کاملBiocide susceptibility of the Burkholderia cepacia complex.
OBJECTIVES The Burkholderia cepacia complex (Bcc) species are important opportunistic pathogens with intrinsic antibiotic resistance. They are also well known as contaminants of disinfectants, yet their biocide susceptibility has not been studied in detail. We investigated Bcc biocide susceptibility and correlated it to their taxonomy, antibiotic susceptibility and ability to form biofilms. M...
متن کاملBurkholderia cepacia complex and cystic fibrosis
The bacteriae previously known as ‘Burkholderia cepacia’ have been reclassified as nine closely related species, sometimes referred to as ‘genomovars’ (Table 1), (Coenye et al, 2001; Mahenthiralingam et al, 2002). Collectively these are commonly referred to as ‘Burkholderia cepacia complex’ (Bcc). The various genomovars have different pathogenic potential (Keig et al, 1999; Bevivino et al, 2002...
متن کاملBurkholderia cepacia Complex as Human Pathogens.
Although sporadic human infection due to Burkholderia cepacia has been reported for many years, it has been only during the past few decades that species within the B. cepacia complex have emerged as significant opportunistic human pathogens. Individuals with cystic fibrosis, the most common inherited genetic disease in Caucasian populations, or chronic granulomatous disease, a primary immunode...
متن کاملFunctional Characterization of Pseudomonas Contact Dependent Growth Inhibition (CDI) Systems
Contact-dependent inhibition (CDI) toxins, delivered into the cytoplasm of target bacterial cells, confer to host strain a significant competitive advantage. Upon cell contact, the toxic C-terminal region of surface-exposed CdiA protein (CdiA-CT) inhibits the growth of CDI- bacteria. CDI+ cells express a specific immunity protein, CdiI, which protects from autoinhibition by blocking the activit...
