| sulfonolipids of gliding bacteria. structure of the n-acylaminosulfonates. | earlier (godchaux, w., and leadbetter, e. r. (1980) j. bacteriol. 144, 592-602; (1983) j. bacteriol. 153, 1238-1246) we demonstrated that an unusual class of sulfonolipids are major components of the cell envelope of gliding bacteria of the genus cytophaga and of closely related genera. one of these lipids, to which we have assigned the trivial name capnine, was purified and was shown to be 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid (which might also be named as 1-deoxy-15-methylhexad ... | 1984 | 6321489 |
| biosynthesis of the sulfonolipid 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid in the gliding bacterium cytophaga johnsonae. | the biosynthesis of the sulfonolipid 2-amino-3-hydroxy-15-methylhexadecane-1-sulfonic acid (capnine) was studied by measuring the incorporation of possible precursors into the lipid by cells grown in the presence of precursors which were labeled with stable isotopes. cells grown on yeast extract in the presence of dl-[3,3-2h2]serine contained 40.1 mol% of the protein-bound serine and 5.0 mol% of the protein-bound cysteine derived from the labeled serine. cells grown in the presence of dl-[3,3-2h ... | 1984 | 6330048 |
| isolation and characterization of nonspreading mutants of the gliding bacterium cytophaga johnsonae. | three approaches were taken to isolate a total of 153 nonspreading mutants derived from our laboratory strain of cytophaga johnsonae, uw101, or from its auxotrophic derivative, uw10538. characterization of 109 of these mutants led to their placement in five general categories: (i) motile, nonspreading (mns) mutants whose cells are motile to various degrees but whose colonies fail to spread on agar gels under any conditions of incubation; (ii) conditional nonspreading (cns) mutants with motile ce ... | 1984 | 6735983 |
| [the level of dna homology in species of the genus cytophaga]. | nucleotide composition, genome size and dna homologies were studied for strains cytophaga johnsonae dsm 425, c. pectinovora dsm 6368, c. saccharophyla dsm 1811, c. aquatilis dsm 2063, c. flevensis dsm 1076, c. lytica atcc 23 178, c. arvensicola dsm 3695, c. heparina dsm 2356. a considerable difference in gs-bases level between species of genus cytophaga (33.3-34.9 mol %) and incertae sedis species (c. heparina and c. arvensicola) (45.0-46.7 mol. %) was shown. the differentiation between freshwat ... | 1995 | 7655657 |

| development of techniques for the genetic manipulation of the gliding bacterium cytophaga johnsonae. | cytophaga johnsonae displays many features that make it an excellent model of bacterial gliding motility. unfortunately, genetic analyses of c. johnsonae, or any related gliding bacteria, were not possible because of a complete lack of selectable markers, cloning vectors, transposons, and convenient methods of gene transfer. as a first step toward a molecular analysis of gliding motility of c. johnsonae, we developed these genetic techniques and tools. common broad-host-range plasmids and transp ... | 1996 | 8550486 |
| negative chemotaxis in cytophaga johnsonae. | chemotaxis, both positive and negative, has been extensively studied in flagellated bacteria, such as escherichia coli and salmonella typhimurium, but not in gliding bacteria. the rapidly motile gliding bacterium cytophaga johnsonae has been seen to be repelled by h2o2, ocl-, and n-chlorotaurine, as well as by low ph. its response to h2o2 was eliminated by catalase. nalidixic acid at 200 microm, which inhibits the growth but not the motility of c. johnsonae, did not interfere with its negative c ... | 1996 | 8640609 |
| development of techniques to genetically manipulate members of the genera cytophaga, flavobacterium, flexibacter, and sporocytophaga. | the bacteroides-cytophaga-flavobacterium branch of the eubacterial phylogenetic tree contains a diverse group of bacterial species. techniques for the genetic manipulation of bacteroides spp. are well developed (a. a. salyers, n. b. shoemaker, and e. p. guthrie, crit. rev. microbiol. 14:49-71, 1987). recently we developed techniques to genetically manipulate the gliding bacterium cytophaga johnsonae (m. j. mcbride and m. j. kempf, j. bacteriol. 178:583-590, 1996). we now demonstrate that some of ... | 1996 | 8702294 |
| immunization with bacterial antigens: flavobacterium and flexibacter infections. | seven bacterial species belonging to the flavobacterium-cytophaga group are currently considered to be pathogenic for fish. because they were only recently described and/or because the disease they provoke has little economic significance, no study has been performed concerning immunization against chryseobacterium scophthalmum, flavobacterium johnsoniae and flexibacter ovolyticus. immunization with flexibacter maritimus has not been investigated, and fish surviving a natural infection appear to ... | 1997 | 9270847 |
| cloning and characterization of the flavobacterium johnsoniae (cytophaga johnsonae) gliding motility gene, glda. | the mechanism of bacterial gliding motility (active movement over surfaces without the aid of flagella) is not known. a large number of nonmotile mutants of the gliding bacterium flavobacterium johnsoniae (cytophaga johnsonae) have been previously isolated, and genetic techniques to analyze these mutants have recently been developed. we complemented a nonmotile mutant of f. johnsoniae (uw102-09) with a library of wild-type dna by using the shuttle cosmid pcp17. the complementing plasmid (pcp100) ... | 1997 | 9342376 |
| development and application of monoclonal antibodies for in situ detection of indigenous bacterial strains in aquatic ecosystems. | strain-specific monoclonal antibodies (mabs) were developed for three different bacterial isolates obtained from a freshwater environment (lake plusssee) in the spring of 1990. the three isolates, which were identified by molecular methods, were as follows: cytophaga johnsonae px62, comamonas acidovorans px54, and aeromonas hydrophila pu7718. these strains represented three species that were detected in high abundance during a set of mesocosm experiments in lake plusssee by the direct analysis o ... | 1997 | 9361440 |
| acetate acts as a protonophore and differentially affects bead movement and cell migration of the gliding bacterium cytophaga johnsonae (flavobacterium johnsoniae). | cells of cytophaga johnsonae (now flavobacterium johnsoniae) are able to translocate on solid surfaces but are unable to swim in liquid media. organelles that may be involved in this gliding motility have not been detected, and the mechanism(s) responsible remains unknown. the movement of latex beads attached to the cell surface is considered by some to be a manifestation of the gliding machinery. in this study, acetate (in nutrient-level quantity, 45 mm) was found to inhibit bead movement on ce ... | 1997 | 9421895 |
| gliding motility in bacteria: insights from studies of myxococcus xanthus. | gliding motility is observed in a large variety of phylogenetically unrelated bacteria. gliding provides a means for microbes to travel in environments with a low water content, such as might be found in biofilms, microbial mats, and soil. gliding is defined as the movement of a cell on a surface in the direction of the long axis of the cell. because this definition is operational and not mechanistic, the underlying molecular motor(s) may be quite different in diverse microbes. in fact, studies ... | 1999 | 10477310 |
| cloning and characterization of the flavobacterium johnsoniae gliding-motility genes gldb and gldc. | the mechanism of bacterial gliding motility (active movement over surfaces without the aid of flagella) is not known. a large number of mutants of the gliding bacterium flavobacterium johnsoniae (cytophaga johnsonae) with defects in gliding motility have been previously isolated, and genetic techniques to analyze these mutants have recently been developed. we complemented a nongliding mutant of f. johnsoniae (uw102-99) with a library of wild-type dna by using the shuttle cosmid pcp26. the comple ... | 2000 | 10648514 |
| transposon insertions in the flavobacterium johnsoniae ftsx gene disrupt gliding motility and cell division. | flavobacterium johnsoniae is a gram-negative bacterium that exhibits gliding motility. to determine the mechanism of flavobacterial gliding motility, we isolated 33 nongliding mutants by tn4351 mutagenesis. seventeen of these mutants exhibited filamentous cell morphology. the region of dna surrounding the transposon insertion in the filamentous mutant cj101-207 was cloned and sequenced. the transposon was inserted in a gene that was similar to escherichia coli ftsx. two of the remaining 16 filam ... | 2000 | 10692373 |
| isolation and identification of cellulolytic bacteria involved in the degradation of natural cellulosic fibres. | in search for bacterial cultures that are able to rapidly degrade cellulosic plant fibres in vitro, 77 cellulolytic strains were isolated from belgian and czech soils after enrichment on flax or sisal fibres as sole sources of carbon. the strains were characterized using fatty acid analysis, and 74 strains were grouped into three major clusters by numerical analysis. the first major cluster contained cellulomonas strains. within this cluster three subclusters could be delineated by principal com ... | 2000 | 10930083 |
| cloning and characterization of the flavobacterium johnsoniae gliding motility genes gldd and glde. | cells of flavobacterium johnsoniae move over surfaces by a process known as gliding motility. the mechanism of this form of motility is not known. cells of f. johnsoniae propel latex spheres along their surfaces, which is thought to be a manifestation of the motility machinery. three of the genes that are required for f. johnsoniae gliding motility, glda, gldb, and ftsx, have recently been described. tn4351 mutagenesis was used to identify another gene, gldd, that is needed for gliding. tn4351-i ... | 2001 | 11418556 |
| members of the cytophaga-flavobacterium-bacteroides phylum as intracellular bacteria of acanthamoebae: proposal of 'candidatus amoebophilus asiaticus'. | three gram-negative, rod-shaped bacteria that were found intracellularly in two environmental and one clinical acanthamoeba sp. isolates were analysed. two endocytobionts showing a parasitic behaviour were propagated successfully outside their amoebal host cells and were identified subsequently by comparative 16s rrna sequence analysis as being most closely affiliated with flavobacterium succinicans (99% 16s rrna sequence similarity) or flavobacterium johnsoniae (98% 16s rrna sequence similarity ... | 2001 | 11553234 |
| mutations in flavobacterium johnsoniae gldf and gldg disrupt gliding motility and interfere with membrane localization of glda. | flavobacterium johnsoniae moves rapidly over surfaces by a process known as gliding motility. the mechanism of this form of motility is not known. four genes that are required for f. johnsoniae gliding motility, glda, gldb, gldd, and ftsx, have recently been described. glda is similar to the atp-hydrolyzing components of atp binding cassette (abc) transporters. tn4351 mutagenesis was used to identify two additional genes, gldf and gldg, that are required for cell movement. gldf and gldg appear t ... | 2002 | 11948149 |
| rapid detection of columnaris disease in channel catfish (ictalurus punctatus) with a new species-specific 16-s rrna gene-based pcr primer for flavobacterium columnare. | a 16-s rrna gene from the chromosomal dna of the fish-pathogenic bacterium flavobacterium columnare (formerly flexibacter columnaris), strain ars-i, was cloned, sequenced and used to design a polymerase chain reaction (pcr) primer set. the primer set amplified a specific 1193-bp dna fragment from f. columnare strains but not from related bacteria, f. psychrophilum, f. aquatile, f. branchiophilum, or other bacterial pathogens of fish, flexibacter maritimus, cytophaga johnsonae, edwardsiella ictal ... | 2003 | 12459241 |
| phylogenetic structure of the genera flexibacter, flexithrix, and microscilla deduced from 16s rrna sequence analysis. | the 16s rdna sequences of 40 strains of 17 species in the genus flexibacter, 5 strains of 4 species in the genus microscilla, and 1 strain of flexithrix dorotheae, including all type strains of approved and validated species in these genera, were determined to reveal their phylogenetic relationships. the 16s rrna sequence analysis demonstrated the extreme heterogeneity of the genera flexibacter and microscilla. the strains examined diverged into 24 distinct lines of descent (1 group included bot ... | 2002 | 12469298 |
| molecular and biochemical characterization of a carbapenem-hydrolysing beta-lactamase from flavobacterium johnsoniae. | flavobacterium johnsoniae cip100931 is resistant to most beta-lactam antibiotics and has a decreased susceptibility to carbapenems. a beta-lactamase gene was cloned and expressed in escherichia coli dh10b. the purified beta-lactamase, john-1, with a pi value of 9.0 and with a determined relative molecular mass of approximately 27 kda was found to be a monomeric zinc-dependent enzyme that hydrolyses penicillins, narrow- and expanded-spectrum cephalosporins, carbapenems, but not monobactams. seque ... | 2003 | 12562690 |

| flavobacterium johnsoniae gldh is a lipoprotein that is required for gliding motility and chitin utilization. | cells of flavobacterium johnsoniae move rapidly over surfaces by gliding motility. the mechanism of this form of motility is not known. six genes (glda, gldb, gldd, gldf, gldg, and ftsx) that are required for gliding have been described. tn4351 mutagenesis was used to identify another gene, gldh, which is required for cell movement. gldh mutants formed nonspreading colonies, and individual cells lacked the cell movements and ability to propel latex spheres along their surfaces that are character ... | 2003 | 14594839 |
| gldi is a lipoprotein that is required for flavobacterium johnsoniae gliding motility and chitin utilization. | cells of flavobacterium johnsoniae glide rapidly over surfaces by an unknown mechanism. seven genes (glda, gldb, gldd, gldf, gldg, gldh, and ftsx) that are required for gliding motility have been described. complementation of the nonmotile mutants uw102-41, uw102-85, and uw102-92 identified another gene, gldi, that is required for gliding motility. gldi mutants formed nonspreading colonies, and individual cells were completely nonmotile. they were also resistant to bacteriophages that infect wil ... | 2004 | 15060031 |
| cytophaga-flavobacterium gliding motility. | flavobacterium johnsoniae, like many other members of the cytophaga-flavobacterium-bacteroides group, displays rapid gliding motility. cells of f. johnsoniae glide over surfaces at rates of up to 10 microm/s. latex spheres added to f. johnsoniae bind to and are rapidly propelled along cells, suggesting that adhesive molecules move laterally along the cell surface during gliding. genetic analyses have identified a number of gld genes that are required for gliding. three gld proteins are thought t ... | 2004 | 15170404 |
| characterization of bacterial diversity in pulque, a traditional mexican alcoholic fermented beverage, as determined by 16s rdna analysis. | the bacterial diversity in pulque, a traditional mexican alcoholic fermented beverage, was studied in 16s rdna clone libraries from three pulque samples. sequenced clones identified as lactobacillus acidophilus, lactobacillus strain asf360, l. kefir, l. acetotolerans, l. hilgardii, l. plantarum, leuconostoc pseudomesenteroides, microbacterium arborescens, flavobacterium johnsoniae, acetobacter pomorium, gluconobacter oxydans, and hafnia alvei, were detected for the first time in pulque. identity ... | 2004 | 15183874 |
| identification of flavobacterium columnare by a species-specific polymerase chain reaction and renaming of atcc43622 strain to flavobacterium johnsoniae. | species-specific polymerase chain reaction (pcr) primers have been designed to identify the causative agent of columnaris disease, flavobacterium columnare. the 16s rrna gene sequences of f. columnare (eight sequences representing the different genotypes of the species) and related species (18 sequences) were aligned and compared to choose specific regions that are unique to f. columnare and do not have significant intraspecies variability. the species-specific regions in the 16s rrna gene were ... | 2004 | 15488382 |
| flavobacterium johnsoniae gldj is a lipoprotein that is required for gliding motility. | cells of flavobacterium johnsoniae glide rapidly over surfaces by an unknown mechanism. eight genes required for gliding motility have been described. complementation of the nonmotile mutant uw102-48 identified another gene, gldj, that is required for gliding. gldj mutants formed nonspreading colonies, and individual cells were completely nonmotile. like previously described nonmotile mutants, gldj mutants were deficient in chitin utilization and were resistant to bacteriophages that infect wild ... | 2005 | 15805509 |

| identification and expression of a host-recognized antigen, fspa, from flavobacterium psychrophilum. | flavobacterium psychrophilum is the aetiological agent of rainbow trout fry syndrome, an economically important disease of immature salmonid fish for which there is no vaccine. convalescent serum from the host, rainbow trout (oncorhynchus mykiss), reacted strongly with a approximately 20 kda, flavobacterium-specific protein antigen (subsequently named fspa) from f. psychrophilum. protein-enriched, detergent-partitioned samples were separated by two-dimensional gel electrophoresis and the protein ... | 2005 | 16151223 |
| flavobacterium johnsoniae gliding motility genes identified by mariner mutagenesis. | cells of flavobacterium johnsoniae glide rapidly over surfaces. the mechanism of f. johnsoniae gliding motility is not known. eight gld genes required for gliding motility have been described. disruption of any of these genes results in complete loss of gliding motility, deficiency in chitin utilization, and resistance to bacteriophages that infect wild-type cells. two modified mariner transposons, himarem1 and himarem2, were constructed to allow the identification of additional motility genes. ... | 2005 | 16199564 |
| influence of temperature adaptation on glucose metabolism in a psychrotrophic strain of cytophaga johnsonae. | selective enrichment of yellow-orange-pigmented, gram-negative bacteria related to cytophaga johnsonae from lake sediment was dependent on low temperatures (ca. 5 degrees c). however, this temperature effect was abolished when excessive amounts of dissolved organic carbon (10 mm n-acetylglucosamine) were added. a psychrotrophic freshwater isolate of c. johnsonae was used to study the physiological versatility of this group. exponential growth rates were found to be dependent on the temperature t ... | 1982 | 16346146 |
| long-term changes in chemostat cultures of cytophaga johnsonae. | long-term studies with a gliding, heterotrophic bacterium, cytophaga johnsonae, were conducted in a glucose-limited chemostat at a high and a low dilution rate. to test the stability of the steady state during long-term experiments the following parameters were monitored: optical density, glucose concentration, glucose uptake potential, atp content of the cells, and plate counts on two different agar media. biomass remained relatively constant, although the observed changes could have been possi ... | 1983 | 16346411 |
| transient responses of glucose-limited cultures of cytophaga johnsonae to nutrient excess and starvation. | cells from glucose-limited chemostat cultures of cytophaga johnsonae were subjected to a sudden relaxation of substrate limitation by injecting the cells into fresh batch cultures. starvation experiments were carried out by injecting glucose-limited cells into batch cultures lacking glucose. transient responses of biomass, glucose uptake and mineralization, atp content, and viability on different agar media were monitored during these nutrient-shift experiments. cells reacted differently dependi ... | 1984 | 16346475 |
| mutations in flavobacterium johnsoniae secdf result in defects in gliding motility and chitin utilization. | secdf mutants of flavobacterium johnsoniae were deficient in gliding motility and chitin utilization. cells of the mutants had reduced levels of gldj protein, which is required for both processes. secdf is similar to escherichia coli secd and secf, which are involved in protein secretion. | 2006 | 16352853 |

| peptidoglycan from bacillus cereus mediates commensalism with rhizosphere bacteria from the cytophaga-flavobacterium group. | previous research in our laboratory revealed that the introduction of bacillus cereus uw85 can increase the populations of bacteria from the cytophaga-flavobacterium (cf) group of the bacteroidetes phylum in the soybean rhizosphere, suggesting that these rhizosphere microorganisms have a beneficial relationship (g. s. gilbert, j. l. parke, m. k. clayton, and j. handelsman, ecology 74:840-854, 1993). in the present study, we determined the frequency at which cf bacteria coisolated with b. cereus ... | 2006 | 16885294 |
| flavobacterium indicum sp. nov., isolated from warm spring water in assam, india. | a polyphasic taxonomic approach was employed to characterize a strain designated gptsa100-9t, which was isolated from water sampled from a warm spring. the micro-organism, comprising gram-negative, strictly aerobic rods, could not grow on nutritionally rich media such as tryptic soy broth. analysis of the 16s rrna gene sequence (1396 nt) of strain gptsa100-9t revealed that it is a member of the genus flavobacterium, sharing 99.8% sequence similarity with the cfb group bacterium strain a0653 (af2 ... | 2006 | 17082401 |
