Within the phylum Bacteroidetes, the gyrB gene, encoding for the B subunit of the DNA gyrase, has been used as a phylogenetic marker for several genera closely related to Flavobacterium. The phylogenies of the complete 16S rRNA gene and the gyrB gene were compared for 33 Antarctic Flavobacterium isolates and 23 type strains from closely related Flavobacterium species. gyrB gene sequences provid...

background neonatal sepsis is a serious problem in neonatal intensive care units, as it causes high rates of morbidity and mortality. objectives the purpose of this study is to evaluate various etiologic agents, antimicrobial susceptibility, clinical manifestations and the mortality rate in an intensive care unit in kashan, iran. patients and methods one hundred and four neonates with documente...

Seven isolates of an unclassified bacterium resembling Flavobacterium spp. were characterized by growth requirements, microscopic examination, biochemical characteristics, antimicrobial susceptibility tests, protein profile analysis, and serologic data. The unclassified isolates were differentiated from Flavobacterium meningosepticum, Flavobacterium odoratum, Flavobacterium balustinum, Flavobac...

The aim of the current study was to develop a molecular system for differential identification of various fish diseases caused by Flavobacterium species. The system uses the hypervariability of the 16S-23S rDNA Intergenic spacer region (ISR) to develop PCR-based sequence analysis assay. For this purpose, eight different 16S-23S rDNA ISR sequences of six different Flavobacterium species were ali...

A strictly aerobic, Gram-staining-negative, rod-shaped, non-motile, yellow-pigmented bacterial strain, designated BX12(T), was isolated from soil collected from the peak area of Wudang Mountain in the city of Shiyan, Hubei province, China. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain BX12(T) was most closely related to Flavobacterium subsaxonicum WB 4.1-42(T) (95.9% 1...

Three isolates of a Gram-negative, catalase- and oxidase-positive, rod-shaped bacterium, isolated from the lung and liver of two beaked whales, were characterized by phenotypic and molecular genetic methods. Based on cellular morphology and biochemical criteria, the isolates were tentatively assigned to the family Flavobacteriaceae, although they did not appear to correspond to any recognized s...

Flavobacterium seoulense strain EM1321(T) is the type strain of Flavobacterium seoulense sp. nov., a proposed novel species within the genus Flavobacterium. This strain is a Gram-reaction-negative, aerobic, rod-shaped bacterium isolated from stream water in Bukhansan National Park, Seoul. This organism is motile by gliding. Here, we describe the features of Flavobacterium seoulense EM1321(T), t...

Five strains (1126-1H-08(T), 51B-09, 986-08, 1084B-08 and 424-08) were isolated from diseased rainbow trout. Cells were Gram-negative rods, 0.7 µm wide and 3 µm long, non-endospore-forming, catalase and oxidase positive. Colonies were circular, yellow-pigmented, smooth and entire on TGE agar after 72 hours incubation at 25°C. They grew in a temperature range between 15°C to 30°C, but they did n...

Flavobacterium enshiense DK69(T) is a Gram-negative, aerobic, rod-shaped, non-motile and non-flagellated bacterium that belongs to the family Flavobacteriaceae in the phylum Bacteroidetes. The high quality draft genome of strain DK69(T) was obtained and has a 3,375,260 bp genome size with a G + C content of 37.7 mol % and 2848 protein coding genes. In addition, we sequenced five more genomes of...
