the taxonomic relationship of certain environmental flavobacteria to the genus weeksella.	forty environmental strains and reference cultures of flavobacterium, cytophaga and weeksella spp. were examined by numerical taxonomy. twenty-seven strains were recovered in four phena. phena 1a and 1b comprised 48% of the strains and were sufficiently similar to the genus weeksella as to suggest possible inclusion in this genus. they could not be accommodated in the existing species w. virosa and w. zoohelcum. strains from phenon 2 appear to belong neither in the flavobacterium or the weeksell ...	1989	2592292
microbiological characteristics of weeksella virosa (formerly cdc group iif) isolated from the human genitourinary tract.	weeksella virosa (formerly cdc group iif) is a nonsaccharolytic, oxidase- and catalase-positive, gram-negative rod which is unable to grow on macconkey agar. at 48 h of incubation on blood or chocolate agar, the colonies present a characteristic appearance: intensely mucoid, adherent, and cream colored as a result of the production of a nondiffusible yellow pigment. this microorganism has been isolated predominantly from the female genitourinary tract, which indicates the opportunity for sexual ...	1990	2229364
response of weeksella virosa peritonitis to imipenem/cilastin.	capd peritonitis is most commonly due to gram positive infection. gram negative bacillary infection is less frequent but is often seen in hospitalized patients or in those on antibiotics. weeksella virosa (formerly known as flavobacterium ii f) has been isolated from the vaginal secretions and urine of normal women. as gram negative colonization typically proceeds from the perineal region, weeksella virosa peritonitis might be expected in women at risk for gram negative peritonitis. a 33-year-ol ...	1991	1680409

a partial phylogenetic analysis of the "flavobacter-bacteroides" phylum: basis for taxonomic restructuring.	on the basis of small subunit rrna sequence analyses five major subgroups within the flavobacteria-bacteroides phylum have been defined. these are tentatively designated the cytophaga subgroup (comprising largely cytophaga species), the flavobacter subgroup (comprising the true flavobacteria and the polyphyletic genus weeksella), the bacteroides subgroup (comprising the bacteroides and certain cytophaga-like bacteria), the sphingobacter subgroup (which contains the known sphingolipid-producing m ...	1992	11541229
riemerella anatipestifer gen. nov., comb. nov., the causative agent of septicemia anserum exsudativa, and its phylogenetic affiliation within the flavobacterium-cytophaga rrna homology group.	the phylogenetic position of the causative agent of septicemia anserum exsudativa, now most often referred to as [moraxella] anatipestifer (brackets indicate a generically misnamed taxon) or "[pasteurella] anatipestifer," was established by performing rrna cistron similarity studies. [moraxella] anatipestifer belongs to rrna superfamily v, together with the genera flavobacterium, cytophaga, flexibacter, weeksella, capnocytophaga, and sphingobacterium. the detailed structure of rrna superfamily v ...	1993	8240957
a transposon-like sequence adjacent to the acci restriction-modification operon.	we have cloned and sequenced the accirm genes from weeksella zoohelcum (the original identification of this strain as acinetobacter calcoaceticus was incorrect). our sequence differs in the coding regions from a previously published sequence by the addition of three nucleotides near the 3' end of the dna methyltransferase-encoding gene (accim). we have sequenced approx. 3 kb beyond this operon. two genes were found, convergently transcribed with the r-m operon. the first of these genes encodes a ...	1995	7607529
phenotypic characteristics, fatty acid composition, and isoprenoid quinone content of cdc group iig bacteria.	eleven strains of eugonic, nonoxidative, gram-negative rods isolated from clinical specimens formed a distinct group that was designated cdc group iig. five of the 11 isolates were from wounds. the phenotypic characteristics of cdc group iig were most similar to those of weeksella species, with the major difference being that cdc group iig strains grew on macconkey agar in 1 to 2 days, did not hydrolyze gelatin, and did not produce urease. all 11 strains of cdc group iig possessed a distinct fat ...	1995	7751393
in vitro activities of quinolones, beta-lactams, tobramycin, and trimethoprim-sulfamethoxazole against nonfermentative gram-negative bacilli.	from 1991 to 1995, 8,975 nonfermentative gram-negative bacilli were isolated from patients at the ohio state university medical center: 71% pseudomonas aeruginosa, 14% stenotrophomonas maltophilia, 7.6% acinetobacter baumannii, and < 2% each of 25 other species. the mics of trovafloxacin (cp-99,219), ciprofloxacin, ofloxacin, ampicillin-sulbactam, piperacillin, piperacillin-tazobactam, ceftazidime, cefoperazone, ceftriaxone, imipenem, tobramycin, and trimethoprim-sulfamethoxazole (tmp-smz) were ...	1996	8726011

isolation of a fastidious bergeyella species associated with cellulitis after a cat bite and a phylogenetic comparison with bergeyella zoohelcum strains.	bergeyella zoohelcum is an uncommon zoonotic pathogen typically associated with cat or dog bites. previously, only five cases of b. zoohelcum infection have been reported. we report the isolation and characterization of a fastidious bergeyella species from acute cellulitis in the upper extremity of a 60-year-old woman. the organism was too fastidious for identification and susceptibility testing with traditional culture methods. the isolate was characterized further by pcr amplification and sequ ...	2004	14715767
proposal to transfer 'aegyptianella ranarum', an intracellular bacterium of frog red blood cells, to the family flavobacteriaceae as 'candidatus hemobacterium ranarum' comb. nov.	'aegyptianella ranarum' (order rickettsiales), an ultrastructurally defined small, gram-negative rod, is known to replicate in the red blood cells of frogs. heretofore, this bacterium has not been characterized genetically. we cloned and sequenced the 16s rrna (1310 bp) and gyrb (718 bp) genes of 'a. ranarum' from a canadian frog blood specimen. in situ hybridization (with an 'a. ranarum' 16s rrna gene polymerase chain reaction product as probe) and electron microscopy confirmed that 'a. ranarum ...	2004	15142244
['in vitro' activity of different antimicrobial agents on gram-negative nonfermentative bacilli, excluding pseudomonas aeruginosa and acinetobacter spp].	gram-negative nonfermentative bacilli (nfb) are widely spread in the environment. besides of difficulties for identification, they often have a marked multiresistance to antimicrobial agents, including those active against pseudomonas aeruginosa. the objective of this study was to evaluate the 'in vitro' activity of different antimicrobial agents on 177 gram-negative nonfermentative bacilli isolates (excluding pseudomonas aeruginosa and acinetobacter spp.) isolated from clinical specimens. minim ...	2005	15991478
evaluation of pyrrolidonyl arylamidase for the identification of nonfermenting gram-negative rods.	to evaluate the activity of pyrrolidonyl arylamidase (pyr) for the differentiation and identification of nonfermenting gram negative rods (nfgnr), 293 isolates were tested. a 24 h culture of each test organism was prepared. from this a 108-109 cfu/ml suspension was added to 0.25 ml of sterile physiologic solution. a pyr disk was then added and the test was incubated for 30 minutes at 35-37 degrees c, at environmental atmosphere. reading was done by adding 1 drop of cinnamaldehyde reagent. strain ...	2007	16822636
