The predominant polar lipids were phosphatidylethanolamine, two unidentified aminolipids and two unidentified lipids. The major fatty acids of strain CJ210T were iso-C15  0, iso-C17  0 3-OH and summed feature 9 (comprising iso-C17  1  ω9c and/or C16  0 10-methyl). Whole genome sequencing revealed that strain CJ210T had a genome of 3.8 Mbp with 36.5 % DNA G+C content. The genome contained several antimicrobial resistance genes including an aminoglycoside-resistant gene. On the basis of the polyphasic taxonomic study, strain CJ210T represents a novel species in the genus Myroides, for which name Myrodies fluvii sp. nov. is proposed. The type strain is CJ210T (=KACC 19954T=JCM 33306T).A novel Gram-negative bacterium, designated G2-14T, was isolated from rhizosphere soil sample collected from apple orchard in Chungju-si, Chungcheongbuk-do, Republic of Korea. Strain G2-14T was a strictly aerobic, non-spore-forming, non-motile and short-rod-shaped bacterium. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain G2-14T was closely related to Mucilaginibacter myungsuensis HMD1056T (96.9 %) and Mucilaginibacter boryungensis BDR-9T (96.8 %). The major cellular fatty acids (>10 %) of strain G2-14T were summed feature 3 (C161 ω6с and/or C161 ω7с) and iso-C150. The predominant quinone and the major polar lipid were menaquinone-7 and phosphatidylethanolamine, respectively. Strain G2-14T produced acetic acid. The DNA G+C content based on whole genome sequences was 46.4 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain G2-14T represents a novel species in the genus Mucilaginibacter, for which the name Mucilaginibacter mali sp. nov. is proposed. The type strain is G2-14T (=KCTC 72533T=NBRC 114179T).Wheat blue dwarf (WBD) is one of the most economically damaging cereal crop diseases in northwestern PR China. The agent associated with the WBD disease is a phytoplasma affiliated with the aster yellows (AY) group, subgroup C (16SrI-C). Since phytoplasma strains within the AY group are ecologically and genetically diverse, it has been conceived that the AY phytoplasma group may consist of more than one species. This communication presents evidence to demonstrate that, while each of the two 16 rRNA genes of the WBD phytoplasma shares >97.5 % sequence similarity with that of the 'Candidatus Phytoplasma asteris' reference strain, the WBD phytoplasma clearly represents an ecologically separated lineage the WBD phytoplasma not only has its unique transmitting vector (Psammotettix striatus) but also elicits a distinctive symptom in its predominant plant host (wheat). In addition, the WBD phytoplasma possesses molecular characteristics that further manifest its significant divergence from 'Ca. P. asteris'. Such molecular characteristics include lineage-specific antigenic membrane proteins and a lower than 95 % genome-wide average nucleotide identity score with 'Ca. P. asteris'. These ecological, molecular and genomic evidences justify the recognition of the WBD phytoplasma as a novel taxon, 'Candidatus Phytoplasma tritici'.Three Gram-stain-negative, rod-shaped, non-spore-forming bacteria, BA1T, Q614T and PB68.1T, isolated from the digestive system of Heterorhabditis entomopathogenic nematodes, were biochemically and molecularly characterized to clarify their taxonomic affiliations. The 16S rRNA gene sequences of these strains suggest that they belong to the Gammaproteobacteria, to the family Morganellacea, and to the genus Photorhabdus. Deeper analyses using whole genome-based phylogenetic reconstructions suggest that BA1T is closely related to Photorhabdus akhursti, that Q614T is closely related to Photorhabdus heterorhabditis, and that PB68.1T is closely related to Photorhabdus australis. In silico genomic comparisons confirm these observations BA1T and P. akhursti 15138T share 68.8 % digital DNA-DNA hybridization (dDDH), Q614T and P. heterorhabditis SF41T share 75.4 % dDDH, and PB68.1T and P. australis DSM 17609T share 76.6  % dDDH. Physiological and biochemical characterizations reveal that these three strains also differ f.Noise-induced auditory symptoms (NIASs) refer to symptoms that develop after exposure to loud noise, where common symptoms are tinnitus and hearing difficulty. If not detected early or prevented, NIASs may lead to the development of noise-induced hearing loss (NIHL). This cross-sectional study aimed to investigate the prevalence rate of common NIASs and contributing occupational factors among manufacturing workers in Brunei Darussalam. The response rate for this study was 81.7%. The prevalence rate of NIASs was 18% and the most commonly reported symptom was 'ears feeling full after leaving a very noisy place' (10.5%). This study showed a strong association between the absence of hearing protective device use (adjusted odds ratio = 2.118, p = 0.040) and having at least one reported NIAS. The study findings can be used to plan and implement policies where there is a risk of occupational noise exposure to prevent NIASs and further development of NIHL.Objectives. Occupational stress and workload are common risk factors among nurses that increase absenteeism, reduce the quality and quantity of patient care, increase care costs and increase the patient safety risk. The relation between these risk factors and oxidative stress levels has not been clearly defined. Methods. This study was conducted with 258 participants (126 nurses as the case group and 132 healthy adults as the control group). selleck chemical Information was collected using a demographic questionnaire, the nurses' occupational stress scale and the NASA task load index workload questionnaire. Blood samples were taken from the participants and then the levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase and total antioxidant capacity (TAC) were measured in the serum samples. Independent t tests and one-way analysis of variance were used for statistical analysis. Results. SOD and TAC were significantly higher and MDA was significantly lower among the case group compared to the control group. TAC levels significantly decreased with increased stress.
