Although resistance of microorganisms to Hg(II) salts has been widely investigated and resistant strains have been reported from many eubacterial genera, there are few reports of mercuric ion resistance in extremophilic microorganisms. Moderately thermophilic mercury resistant bacteria were selected by growth at 62 °C on Luria agar containing HgCl2.(More)
The Burkholderia cepacia complex (BCC) comprises a group of bacteria associated with opportunistic infections, especially in cystic fibrosis patients. B. cenocepacia J2315, of the transmissible ET12 lineage, contains a type III secretion (TTS) gene cluster implicated in pathogenicity. PCR and hybridisation assays indicate that the TTS gene cluster is(More)
Burkholderia cepacia, an important opportunist pathogen, is genetically heterogeneous. The B. cepacia complex has been subdivided into a number of genospecies or genomovars. A flagellin gene PCR-RFLP method was applied to a representative panel of strains of known genomovar. The technique was able to distinguish strains of B. multivorans from other members(More)
Granulocyte/macrophage colony-stimulating factors (CSF) were found in large-scale serum-free cultures of porcine blood leukocytes. The factors were concentrated from the conditioned culture medium of Concanavalin A-stimulated leukocytes using ammonium sulfate salting-out fractionation. The protein precipitate at 45-90% salt saturation contained two CSF(More)
Resistance to mercuric ions in bacteria is conferred by mercuric reductase, which reduces Hg(II) to Hg(0) in the cytoplasmic compartment. Specific mercuric ion transport systems exist to take up Hg(II) salts and deliver them to the active site of the reductase. This short review discusses the role of transport proteins in resistance and the mechanism of(More)
Using probes constructed from Ralstonia solanacearum and Burkholderia pseudomallei, putative type III secretion (TTS) genes were identified in Burkholderia cepacia J2315 (genomovar III). A cosmid clone containing DNA with homology to five TTS genes was sub-cloned and regions were sequenced in order to design oligonucleotides for polymerase chain reaction(More)
PCR tests were used to assign genomovar status to 39 non-cystic fibrosis (non-CF) and 11 CF Burkholderia cepacia complex isolates from patients in hospitals in Recife, Brazil. Non-CF isolates were assigned to genomovar IIIA (71.8%), genomovar I (15.4%), B. vietnamiensis (7.7%), and B. multivorans (5.1%). CF isolates were assigned to genomovar IIIA (18.2%),(More)
Mercuric ion resistance in bacteria requires transport of mercuric ions (Hg2+) into the cytoplasmic compartment where they are reduced to the less toxic metallic mercury (Hg0) by mercuric reductase (MR). The long-established model for the resistance mechanism predicts interactions between the inner membrane mercuric ion transporter, MerT, and the N-terminal(More)
