| hafnia paralvei sp. nov., formerly known as hafnia alvei hybridization group 2. | it has been shown previously, based largely on dna-dna hybridizations and partial 16s rrna gene sequencing, that hafnia alvei is genotypically heterogeneous and consists of at least two dna hybridization groups (hgs). in the present study, the taxonomic status of h. alvei hgs 1 and 2 was reassessed. a panel of 24 reference strains and isolates previously assigned to one of the two hgs in h. alvei was subjected to (gtg)5-pcr fingerprinting; this resulted in the delineation of two (gtg)5-pcr clust ... | 2010 | 19734282 |
| a case of bacteremia caused by hafnia paralvei. | the genus hafnia, a member of the enterobacteriaceae, is widespread in nature and rarely causes human infection. we describe a case of an 85-year-old japanese man hospitalized consequent to suspected cholecystitis, in which hafnia sp. was recovered from the blood culture concomitantly with enterococcus faecalis. sequencing of the 16s ribosomal rna gene sequence and phenotyping with id 32 e revealed that the recovered hafnia sp. was considered to be hafnia alvei genomosp. 2 (atcc 29927), recently ... | 2011 | 21553084 |
| clinical and laboratory diagnostic characteristics and cytotoxigenic potential of hafnia alvei and hafnia paralvei strains. | a collection of 68 strains of hafnia previously identified to species by 16s rrna gene sequencing were investigated for simple phenotypic properties that could aid in their recognition in the clinical laboratory. four tests including malonate utilization, fermentation of salicin and d-arabinose, and expression of ß-glucosidase activity correctly assigned each strain to either h. alvei or h. paralvei. antibiotic susceptibility profiles for 35 hafnia alvei and hafnia paralvei isolates were generat ... | 2011 | 21795516 |
| predominant enterobacteria on modified-atmosphere packaged meat and poultry. | enterobacteria on modified-atmosphere (ma) packaged meat (n = 54) and poultry (n = 32) products were enumerated, and 899 isolates were picked and ribotyped. for identification, 16s rrna genes of representative strains were sequenced and analyzed. altogether 54 (60%) of the samples contained enterobacteria >10(4) cfu/g. in 34% of the poultry samples, enterobacteria counts were >10(6) cfu/g suggesting that enterobacteria may contribute to spoilage of ma packaged poultry. the enterobacteria identif ... | 2012 | 23541191 |
| draft genome sequence of hafnia paralvei strain gta-haf03. | hafnia paralvei is a gram-negative member of the enterobacteriaceae family, closely related to the opportunistic pathogen hafnia alvei. we report here the first draft genome sequence of h. paralvei, from the beef trim isolate gta-haf03, consisting of a 5.0-mbp assembly encoding 4,382 proteins and 90 predicted rnas. | 2015 | 25700416 |
| hafnia psychrotolerans sp. nov., isolated from lake water. | a psychrotolerant, gram-stain-negative, motile, aerobic, peritrichous bacterium, strain djc1-1(t), was isolated from lake dajiaco, tibetan plateau, china. the strain was negative for citrate utilization, lipase activity and α-glucosidase, but positive for the voges-proskauer reaction and n-acetyl-β-glucosaminidase. 16s rrna gene sequence analysis indicated that hafnia paralvei atcc 29927(t), hafnia alvei atcc 13337(t), serratia grimesii dsm 30063(t) and serratia plymuthica dsm 4540(t) were the c ... | 2015 | 25563917 |

| hafnia, an enterobacterial genus naturally resistant to colistin revealed by three susceptibility testing methods. | to determine the susceptibility to colistin of hafnia alvei and hafnia paralvei, and to compare methods for colistin resistance detection in the hafnia genus. | 2017 | 28586429 |
