Phylogenetic analysis based on the 16S rRNA gene revealed that strain KK2020170T belongs to the genus Flavobacterium, with Flavobacterium haoranii LQY-7T (98.1% similarity) being its closest relative, followed by Flavobacterium sediminis MEBiC07310T (96.9%) and Flavobacterium urocaniciphilum YIT 12746T (96.0%). Whole-genome shotgun sequencing showed that strain KK2020170T, when paralleled with F. haoranii LQY-7 T, had 81.3% average nucleotide identity, and 24.6% in silico DNA–DNA hybridization values, respectively. The DNA G + C content of strain KK2020170T was 31.1 mol%. The most abundant fatty acids (> 10%) of strain KK2020170T were iso-C15: 0, iso-C17: 0 3-OH and iso-C15: 1 G. The dominant respiratory quinone of the strain was menaquinone MK-6. Based on the phylogenetic and phenotypic analysis results, we propose that strain KK2020170T represents a novel species, for which the name Flavobacterium okayamense sp. nov. has been proposed. The type strain is KK2020170T (= ATCC TSD-280 T = NBRC 115344 T). en-copyright= kn-copyright= en-aut-name=KitaharaKei en-aut-sei=Kitahara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MuzemboBasilua Andre en-aut-sei=Muzembo en-aut-mei=Basilua Andre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorohoshiSho en-aut-sei=Morohoshi en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KunihiroTadao en-aut-sei=Kunihiro en-aut-mei=Tadao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TazatoNozomi en-aut-sei=Tazato en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhnoAyumu en-aut-sei=Ohno en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UesakaKazuma en-aut-sei=Uesaka en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaniguchiMakoto en-aut-sei=Taniguchi en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=TechnoSuruga Laboratory Co., Ltd kn-affil= affil-num=4 en-affil=TechnoSuruga Laboratory Co., Ltd kn-affil= affil-num=5 en-affil=TechnoSuruga Laboratory Co., Ltd kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Bioagricultural Sciences, Nagoya University kn-affil= affil-num=8 en-affil=Oral Microbiome Center, Taniguchi Dental Clinic kn-affil= affil-num=9 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Bacteroidota kn-keyword=Bacteroidota en-keyword=Flavobacterium kn-keyword=Flavobacterium en-keyword=New taxa kn-keyword=New taxa en-keyword=Sea water kn-keyword=Sea water END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue= article-no= start-page=521 end-page=525 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Isolation and identification of soil bacteria resistant to surfactants in washing detergents en-subtitle= kn-subtitle= en-abstract= kn-abstract=Linear alkylbenzene sulfonate (LAS) and polyoxyethylene lauryl ether (POLE) are the major surfactants in washing detergents. In the present study, we isolated surfactant-resistant bacteria from soil samples collected from a sports ground and a farm field. The samples were treated with 2.0% LAS or POLE at 25°C for 30 min and cultivated on agar plates at 25°C for several days, after which manifold bacterial colonies were isolated. Thereafter, we tested the ability of each bacterial isolate to resist the antibacterial activity of the surfactant. Ten LAS-resistant strains were isolated, and all were found to be Gram-negative bacteria such as Enterobacter and Pseudomonas. On the other hand, 18 POLE-resistant strains were isolated, of which 14 were Gram-positive bacteria including Bacillus and Microbacterium. Notably, one POLE-resistant strain was identified as Bacillus cereus, a potential causative agent for foodborne illness. The genera of LAS- and POLE-resistant bacteria did not overlap. Therefore, the combination of LAS and POLE could be more effective to eliminate soil bacteria from clothes and/or daily necessities. en-copyright= kn-copyright= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkuboNaomi en-aut-sei=Okubo en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitsumoriSatoko en-aut-sei=Mitsumori en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University Okayama‐City Okayama Japan kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences Okayama University Okayama‐City Okayama Japan kn-affil= en-keyword=Surfactant kn-keyword=Surfactant en-keyword=Washing detergent kn-keyword=Washing detergent en-keyword=Linear alkylbenzene sulfonate kn-keyword=Linear alkylbenzene sulfonate en-keyword=Soil bacteria kn-keyword=Soil bacteria END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=4 article-no= start-page=1633 end-page=1639 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An extracellular serine protease produced by Vibrio vulnificus NCIMB 2137, a metalloprotease-gene negative strain isolated from a diseased eel en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vibrio vulnificus is a ubiquitous estuarine microorganism but causes fatal systemic infections in immunocompromised humans, cultured eels or shrimps. An extracellular metalloprotease VVP/VvpE has been reported to be a potential virulence factor of the bacterium; however, a few strains isolated from a diseased eel or shrimp were recently found to produce a serine protease termed VvsA, but not VVP/VvpE. In the present study, we found that these strains had lost the 80 kb genomic region including the gene encoding VVP/VvpE. We also purified VvsA from the culture supernatant through ammonium sulfate fractionation, gel filtration and ion-exchange column chromatography, and the enzyme was demonstrated to be a chymotrypsin-like protease, as well as those from some vibrios. The gene vvsA was shown to constitute an operon with a downstream gene vvsB, and several Vibrio species were found to have orthologues of vvsAB. These findings indicate that the genes vvp/vvpE and vvsAB might be mobile genetic elements. en-copyright= kn-copyright= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=JiyouWang en-aut-sei=Jiyou en-aut-mei=Wang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatohKeizo en-aut-sei=Katoh en-aut-mei=Keizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SenohMitsutoshi en-aut-sei=Senoh en-aut-mei=Mitsutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MizunoTamaki en-aut-sei=Mizuno en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MaeharaYoko en-aut-sei=Maehara en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci affil-num=5 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci affil-num=6 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci en-keyword=Polymerase chain reaction kn-keyword=Polymerase chain reaction en-keyword=Purification kn-keyword=Purification en-keyword=Serine protease kn-keyword=Serine protease en-keyword=Metalloprotease kn-keyword=Metalloprotease en-keyword=Vibrio vulnificus kn-keyword=Vibrio vulnificus END start-ver=1.4 cd-journal=joma no-vol=125 cd-vols= no-issue=1 article-no= start-page=35 end-page=39 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An epidemiologically rare case of Vibrio vulnificus infection that occurred in October in an inland city of Japan kn-title=内陸地津山で発症した季節外れのVibrio vulnificus感染症 en-subtitle= kn-subtitle= en-abstract= kn-abstract= A 68-year-old man with alcohol addiction, who lived in the suburbs of Tsuyama, an inland city located in northeast Okayama prefecture, was transported to the emergency unit of the Tsuyama Central Hospital in a state of cardiopulmonary arrest (CPA). Despite rigorous systemic investigation and treatment, the patient died 2 hours after arrival. After his death, Vibrio vulnificus was isolated from his blood culture.  Vibrio vulnificus causes fatal infection in humans, usually only in areas located close to the sea where appropriate temperature and suitable salt concentration for its growth are available. Therefore, its occurrence is epidemiologically restricted ; in Japan, the western coastal areas, especially in summers, are reported to be the high-risk regions. This is a rare case because it occurred in a city approximately 50 kilometers from both the Sea of Japan and the Pacific coast of Okayama, and at the end of October in 2011. Economic development and distribution systems have made it possible to transport various food products from coastal areas or abroad to any place in a short time, such that these infections can potentially develop in areas other than expected. We should be aware of the increasing risk of Vibrio vulnificus infection during any season and at any place, especially in patients with abnormal liver function. en-copyright= kn-copyright= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name=萩谷英大 kn-aut-sei=萩谷 kn-aut-mei=英大 aut-affil-num=1 ORCID= en-aut-name=ShiotaSumiko en-aut-sei=Shiota en-aut-mei=Sumiko kn-aut-name=塩田澄子 kn-aut-sei=塩田 kn-aut-mei=澄子 aut-affil-num=2 ORCID= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name=三好伸一 kn-aut-sei=三好 kn-aut-mei=伸一 aut-affil-num=3 ORCID= en-aut-name=KuroeYasutoshi en-aut-sei=Kuroe en-aut-mei=Yasutoshi kn-aut-name=黒江泰利 kn-aut-sei=黒江 kn-aut-mei=泰利 aut-affil-num=4 ORCID= en-aut-name=NojimaHiroyoshi en-aut-sei=Nojima en-aut-mei=Hiroyoshi kn-aut-name=野島宏悦 kn-aut-sei=野島 kn-aut-mei=宏悦 aut-affil-num=5 ORCID= en-aut-name=OtaniShinkichi en-aut-sei=Otani en-aut-mei=Shinkichi kn-aut-name=大谷晋吉 kn-aut-sei=大谷 kn-aut-mei=晋吉 aut-affil-num=6 ORCID= en-aut-name=SugiyamaJunichi en-aut-sei=Sugiyama en-aut-mei=Junichi kn-aut-name=杉山淳一 kn-aut-sei=杉山 kn-aut-mei=淳一 aut-affil-num=7 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name=内藤宏道 kn-aut-sei=内藤 kn-aut-mei=宏道 aut-affil-num=8 ORCID= en-aut-name=KawanishiSusumu en-aut-sei=Kawanishi en-aut-mei=Susumu kn-aut-name=川西進 kn-aut-sei=川西 kn-aut-mei=進 aut-affil-num=9 ORCID= en-aut-name=HagiokaShingo en-aut-sei=Hagioka en-aut-mei=Shingo kn-aut-name=萩岡信吾 kn-aut-sei=萩岡 kn-aut-mei=信吾 aut-affil-num=10 ORCID= en-aut-name=MorimotoNaoki en-aut-sei=Morimoto en-aut-mei=Naoki kn-aut-name=森本直樹 kn-aut-sei=森本 kn-aut-mei=直樹 aut-affil-num=11 ORCID= affil-num=1 en-affil= kn-affil=津山中央病院 救命救急センター affil-num=2 en-affil= kn-affil=就実大学薬学部 病原微生物学 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 衛生微生物化学 affil-num=4 en-affil= kn-affil=津山中央病院 救命救急センター affil-num=5 en-affil= kn-affil=津山中央病院 救命救急センター affil-num=6 en-affil= kn-affil=津山中央病院 救命救急センター affil-num=7 en-affil= kn-affil=津山中央病院 救命救急センター affil-num=8 en-affil= kn-affil=津山中央病院 救命救急センター affil-num=9 en-affil= kn-affil=津山中央病院 救命救急センター affil-num=10 en-affil= kn-affil=津山中央病院 救命救急センター affil-num=11 en-affil= kn-affil=津山中央病院 救命救急センター en-keyword=Vibrio vulnificus kn-keyword=Vibrio vulnificus END start-ver=1.4 cd-journal=joma no-vol=57 cd-vols= no-issue=6 article-no= start-page=904 end-page=908 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Inactivation of Vibrio vulnificus hemolysin through mutation of the N- or C-terminus of the lectin-like domain en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vibrio vulnificus is an etiological agent causing serious systemic infections in the immunocompromised humans or cultured eels. This species commonly produces a hemolytic toxin consisting of the cytolysin domain and the lectin-like domain. For hemolysis, the lectin-like domain specifically binds to cholesterol in the erythrocyte membrane, and to form a hollow oligomer, the toxin is subsequently assembled on the membrane. The cytolysin domain is essential for the process to form the oligomer. Three-dimensional structure model revealed that two domains connected linearly and the C-terminus was located near to the joint of the domains. Insertion of amino acid residues between two domains was found to cause inactivation of the toxin. In the C-terminus, deletion, substitution or addition of an amino acid residue also elicited reduction of the activity. However, the cholesterol-binding ability was not affected by the mutations. These results suggest that mutation of the C- or N-terminus of the lectin-like domain may result in blockage of the toxin assembly. en-copyright= kn-copyright= en-aut-name=MiyoshiShin-ichi en-aut-sei=Miyoshi en-aut-mei=Shin-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AbeYuki en-aut-sei=Abe en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SenohMitsutoshi en-aut-sei=Senoh en-aut-mei=Mitsutoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizunoTamaki en-aut-sei=Mizuno en-aut-mei=Tamaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaeharaYoko en-aut-sei=Maehara en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakaoHiroshi en-aut-sei=Nakao en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University affil-num=5 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University affil-num=6 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University en-keyword=Vibrio vulnificus kn-keyword=Vibrio vulnificus en-keyword=Hemolysin kn-keyword=Hemolysin en-keyword=Cell-free translation kn-keyword=Cell-free translation en-keyword=Site-directed mutagenesis kn-keyword=Site-directed mutagenesis END start-ver=1.4 cd-journal=joma no-vol=143 cd-vols= no-issue=3 article-no= start-page=230 end-page=234 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20101015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevalence and antimicrobial resistance of Salmonella in retail foods in northern China en-subtitle= kn-subtitle= en-abstract= kn-abstract=A total of 387 retail meat, seafood and milk powder samples were collected from nine cities in northern China in 2005 and screened for the presence of Salmonella. Salmonella strains isolated were subjected to serotyping and antimicrobial susceptibility testing. Salmonella was isolated from 81 (20.9%, 81/387) samples and classified into 23 serotypes. The isolates were frequently resistant to sulfamethoxazole (86.4%), sulfamethoxazole/trimethoprim (48.1%), nalidixic acid (30.9%), tetracycline (19.8%), carboxybenzylpenicillin (17.3%), amoxicillin (17.3%) and ampicillin (16.0%). The multiple resistance (resistance to ≥ 3 antibiotics) was found in 29.6% (n = 24) isolates. Additionally, 4 isolates from chicken displayed the ACSSuTNx profile, resistant to ampicillin, chloramphenicol, streptomycin, sulfonamide, tetracycline and nalidixic acid, in particular, strain HBS084 showing the resistance to as many as 20 antibiotics. Salmonella from chicken showed the higher frequency of antimicrobial resistance. Our findings indicate that in northern China food products of animal origin can be a source of exposure for consumers to multiresistant Salmonella strains en-copyright= kn-copyright= en-aut-name=YanHe en-aut-sei=Yan en-aut-mei=He kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LiLin en-aut-sei=Li en-aut-mei=Lin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AlamM.
