| diversity and evolution of bdellovibrio-and-like organisms (balos), reclassification of bacteriovorax starrii as peredibacter starrii gen. nov., comb. nov., and description of the bacteriovorax-peredibacter clade as bacteriovoracaceae fam. nov. | a phylogenetic analysis of bdellovibrio-and-like organisms (balos) was performed. it was based on the characterization of 71 strains and on all consequent 16s rrna gene sequences available in databases, including clones identified by data-mining, totalling 120 strains from very varied biotopes. amplified rdna restriction analysis (ardra) accurately reflected the diversity and phylogenetic affiliation of balos, thereby providing an efficient screening tool. extensive phylogenetic analysis of the ... | 2004 | 15388693 |
| characterization of outer membrane protein fractions of bdellovibrionales. | bdellovibrio-and-like organisms (balos) are predatory bacteria that prey upon gram-negative bacteria and are taxonomically subsumed in the order bdellovibrionales. despite their unique lifestyle, these bacteria show remarkable genotypic diversities. the outer membrane of the predators is likely to play an important role during the recognition and invasion stage, as well as in the intraperiplasmic growth phase. in this study, the outer membrane protein fractions of type strains of bdellovibrio, b ... | 2005 | 15668021 |
| structure analysis of a soil community of predatory bacteria using culture-dependent and culture-independent methods reveals a hitherto undetected diversity of bdellovibrio-and-like organisms. | bdellovibrio-and-like organisms (balos) are widespread obligatory predators of other gram-negative bacteria. their detection by culture-dependent methods is complicated as their replication is totally dependent upon the availability of an appropriate prey. because balos do not form numerically dominant groups within microbial communities, non-specific culture-independent tools also generally fail to detect them. we designed sets of 16s rrna primers that specifically target balos. polymerase chai ... | 2006 | 16913926 |
| biostimulation of estuarine microbiota on substrate coated agar slides: a novel approach to study diversity of autochthonous bdellovibrio- and like organisms. | characterization of bdellovibrio- and like organisms (balos) from environmental samples involves growing them in the presence of gram-negative prey bacteria and isolation of balo plaques. this labor-intensive enrichment and isolation procedure may impede the detection and phylogenetic characterization of uncultivable balos. in this article, we describe a simple slide biofilm assay to improve detection and characterization of balo microbiota. agar spiked with biostimulants such as yeast extract ( ... | 2008 | 17968612 |
| phylogenetic relationships amongst the saltwater members of the genus bacteriovorax using rpob sequences and reclassification of bacteriovorax stolpii as bacteriolyticum stolpii gen. nov., comb. nov. | members of the saltwater genus bacteriovorax, formerly known as the marine bdellovibrio, are obligate predatory bacteria that prey selectively on other gram-negative bacteria. previous phylogenetic analysis based on the 16s rrna genes of saltwater bacteriovorax isolates from environmental samples revealed 11 distinct phylogenetic clusters based on > or =96.5 % gene sequence similarity. in other micro-organisms, the gene coding for the beta-subunit of rna polymerase (rpob) has been shown to be mo ... | 2008 | 18450714 |
| the protective effect of bdellovibrio-and-like organisms (balo) on tilapia fish fillets against salmonella enterica ssp. enterica serovar typhimurium. | to characterize freshwater bdellovibrio-and-like organisms (balo) isolated in china and examine their potential in controlling growth of salmonella enterica ssp. enterica serovar typhimurium on tilapia fillets. | 2010 | 20880363 |
| killing of anaerobic pathogens by predatory bacteria. | recently, the predation of bdellovibrio bacteriovorus on a periodontal pathogen has been described. the current study explores the potential antimicrobial activity of a range of predatory bacteria against key periodontal pathogens. a number of representatives from the bdellovibrio, bacteriovorax and peredibacter lineages (called 'balos') were tested for their activity towards a group of key periodontal pathogens and an optimal multiplicity of infection was established. as the oral cavity contain ... | 2010 | 21214872 |
| biological characterization of two marine bdellovibrio-and-like organisms isolated from daya bay of shenzhen, china and their application in the elimination of vibrio parahaemolyticus in oyster. | bdellovibrio-and-like organisms (balos) are a group of highly motile delta-proteobacteria that prey on other gram-negative bacteria. however, nothing is known of the application potential of marine balos in safeguarding seafood safety. here, biological characterization of two marine balos strains and their application in the elimination of vibrio parahaemolyticus in oyster (crassostrea ariakensis) at the laboratory scale were investigated. balos strains bdh12 and bdhsh06 were isolated from sedim ... | 2011 | 21899909 |
| bacterial predators possess unique membrane lipid structures. | bdellovibrio-and-like organisms (balo) are a phylogenetically diverse group of predatory prokaryotes that consists of the two families bdellovibrionaceae and bacteriovoracaceae. we investigated the phospholipid composition of the three important balo strains bacteriovorax stolpii (dsm 12778), bdellovibrio bacteriovorus hd100 (dsm 50701) and peredibacter starrii (dsm 17039). we confirmed the presence of sphingophosphonolipids in b. stolpii, while we characterized sphingophosphonolipids with a 2-a ... | 2011 | 21984111 |
