The Chinese revered a species of aquatic reptile known as Pelodiscus sinensis as both an edible and medicinal species. When artificially breeding, many deaths occurred at the farmed P. sinensis, mainly due to excessive breeding density, water contamination, and turtles biting each other secondary to bacterial infections. In this study, an isolate of gram‐negative bacteria WH0623 was isolated from the liver and kidney of diseased P. sinensis to trace the potential pathogen of this disease. Based on biochemical characteristics and 16S rRNA gene sequencing analyses, this isolated strain of WH0623 was identified as Chryseobacterium indologenes. The strain's median lethal dose (LD50) was 3.3 × 105 colony‐forming units (CFU)/g per fish weight tested using artificial infection. Histopathological analysis revealed pathological changes, including cell swelling, hyperaemia, and necrosis in many tissues. Antibiotic susceptibility tests revealed that the bacteria WH0623 was susceptible to doxycycline, sulphonamides, ceftazidime, norfloxacin, and ciprofloxacin. These antibiotics could treat the disease. In conclusion, the pathogen causing the death of farmed P. sinensis was isolated and identified, and a drug‐sensitive test was conducted. Our findings contribute to the future diagnosis and treatment of the disease.

A polyphasic taxonomic study was carried out on strain ES2T, isolated from sediment of a wetland created to remediate acid drainage from a coal mine. The rod-shaped bacterium formed yellow/orange pigmented colonies and produced the pigment flexirubin. The 16S rRNA gene sequence results assigned the strain to Chryseobacterium, with 98.9 and 98.3 % similarity to Chryseobacterium vietnamense and Chryseobacterium cucumeris, respectively. Computation of the average nucleotide identity and digital DNA–DNA hybridization values with the closest phylogenetic neighbours of ES2T revealed genetic differences at the species level, which were further substantiated by differences in several physiological characteristics. The dominant fatty acids of strain ES2T were iso-C15 : 0, iso-C17 : 1 ω9c, iso C17 : 0 3-OH, and iso-C15 : 0 2-OH. The DNA G+C content was 35.5 mol%. The major polar lipid was phosphatidylethanolamine while menaquinone-6 was the only menaquinone found. This bacterium has been previously shown to possess metallophore activity towards rare earth elements, and based on genome sequencing, possesses all required genes for siderophore production/activity, possibly identifying the source of this unique ability. On the basis of the results obtained here, this bacterium is assigned to the genus Chryseobacterium as representing a new species with the name Chryseobacterium metallicongregator sp. nov., type strain ES2T (=NRRL B-65679T=KCTC 102120T).

A Gram-stain-negative, yellow-pigmented bacterium, designated as L7T, was isolated from seeds of Alhagi sparsifolia Shap., a leguminous plant that grows in northwest PR China. Strain L7T was found to be non-flagellated, non-spore forming rods which can grow at 10–37 °C, pH 6.0–8.5 and in 0–3 % (v/w) NaCl concentration. The 16S rRNA gene sequence analysis showed that strain L7T belongs to the genus Chryseobacterium with sequence similarities to Chryseobacterium vietnamense GIMN1.005T (98.1%), C. bernardetii NCCTC13530T (98.0%), C. vrystaatense LMG 22846T (97.9%), C. nakagawai NCTC13529T (97.7%), C. shigense DSM 17126T (97.6%) and C. rhizosphaerae RSB3-1T (97.5%). The average nucleotide identity of strain L7T to 31 reference strains were 78.6–85.6 %, lower than the species delineation threshold of 95 %. MK-6 was the only respiratory quinone of L7T and major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 1 ω7c and/or C16 : 1 ω6c, isoC17 : 1 ω9c and/or C16 : 0 10-methyl. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, three unidentified aminophospholipids, two unidentified aminolipids, three unidentified glycolipids and two unidentified lipids. The G+C content of the genome was 38.58 mol%. On the basis of polyphasic taxonomy analyses in this study, strain L7T is considered to represent a novel species in the genus Chryseobacterium , for which the name Chryseobacterium endalhagicum sp. nov. is proposed. The type strain is L7T (=MCCC 1K05687T=JCM 34506T)
