کنترل بیولوژیکی بیماری های ناشی از rhizoctonia solani به عنوان یک روش جایگزین مواد شیمیایی مورد توجه و مطالعات وسیعی قرار گرفته است. باکتری burkholderia (pseudomonas) cepacia از جمله گونه هایی است که در سال های اخیر مورد توجه بیشتری قرار گرفته است. باکتری b. cepacia به عنوان یک نماتد کش بوسیله سازمان حفاظت محیط زیست امریکا به ثبت رسیده است. براساس تحقیقات جدید تثبیت نیتروژن در خاک یک خصوصیت ع...
Background and Aim: Cystic fibrosis is a common hereditary and autosomal disorder. One of the factors in cystic fibrosis is Burkholderia cepacia which can be transmitted through the sharing of admitted patients with hospitalized patients. Purpose of this study, was isolation and identification of Burkholderia cepacia from respiratory secretions from Masih Daneshvari Hospital cystic fibrosis...
Background: Complex of Burkholderia cepacia is one of the main and serious causes of infections in cystic fibrosis patients that can be highly transmissible. Small hospital outbreaks are frequent and are usually due to a single contaminated environmental source. The pulsed-field gel electrophoresis (PFGE) is widely used to identify the strain emission sources in cystic fibrosis patients. The ai...
Abstract Background and Objective: Burkholderia cepacia complex (BCC) is a plant pathogen that is an important mortality factor in immune-compromised and hospitalized patients. We aimed to Isolate and Characterize the Burkholderia Cepacia Strains from Hospitalized Patients in the Hospitals of West Guilan Province. Material and Methods: This study was conducted on 90 saliva and blood ...
One hundred thirty-eight clinical isolates of the Burkholderia cepacia complex (Bcc) were identified using a modified strategy that involved PCR detection of the cblA gene for the ET12 lineage simultaneously with detection of the Bcc recA PCR product; recA sequence cluster analysis also was part of the strategy. Four strains could not be assigned to any of the known genomovars.
We performed an integrated genotypic and phenotypic analysis of 128 strains of the genera Burkholderia, Ralstonia, and Pseudomonas in order to study the taxonomic structure of Burkholderia cepacia and its relationships with other Burkholderia species. Our data show that presumed B. cepacia strains isolated from cystic fibrosis patients belong to at least five distinct genomic species, one of wh...
Two new species, Burkholderia multivorans and Burkholderia vietnamiensis, and three genomovars (genomovars I, III, and IV) currently constitute the Burkholderia cepacia complex. A panel of 30 well-characterized strains representative of each genomovar and new species was assembled to assist with identification, epidemiological analysis, and virulence studies on this important group of opportuni...
Burkholderia cenocepacia is an opportunistic pathogen that belongs to Burkholderia cepacia complex (BCC). Burkholderia cenocepacia strain CEIB S5-2 was isolated from agricultural soils in Morelos, Mexico, and previously has shown its abilities for bioremediation. In this study, we report the draft genome sequence of Burkholderia cenocepacia strain CEIB S5-2.
Nineteen Burkholderia cepacia-like isolates of human and environmental origin could not be assigned to one of the seven currently established genomovars using recently developed molecular diagnostic tools for B. cepacia complex bacteria. Various genotypic and phenotypic characteristics were examined. The results of this polyphasic study allowed classification of the 19 isolates as an eighth B. ...
We demonstrate that all nine species of the Burkholderia cepacia complex can express the mucoid phenotype. A survey of clinical isolates showed that strains of B. cenocepacia, the most virulent species of the complex, are most frequently nonmucoid. Additionally, isolates from patients with chronic infections can convert from mucoid to nonmucoid.
