Microcella flavibacter sp. nov., isolated from marine sediment,and reclassification of Chryseoglobus frigidaquae,Chryseoglobus indicus,and Yonghaparkia alkaliphila as Microcella frigidaquae comb. nov., Microcella indica nom. nov., and Microcella alkalica nom. nov.

A novel Gram-staining positive, aerobic, rod-shaped, non-motile and yellow-pigmented actinobacterium, designated strain WY83^T, was isolated from a marine sediment of Indian Ocean. Strain WY83^T grew optimally at 30–35 °C, pH 7–8 and with 0–3% (w/v) NaCl. The predominant menaquinones were MK-10, MK-11 and MK-12, and the major fatty acids were C_19:1 ω9c/C19:1 ω11c, anteiso-C_15:0, C_17:0 3OH, and iso-C_16:0. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol and one unidentified glycolipid. The cell-wall peptidoglycan contained lysine as a diamino acid. The DNA G?+?C content was 72.3 mol%. Phylogenetic analysis based on 16S rRNA gene sequences and ninety-two bacterial core genes indicated that strain WY83^T formed an evolutionary lineage with Chryseoglobus frigidaquae JCM 14730^T, Chryseoglobus indicus CTD02-10-2^T, Yonghaparkia alkaliphila JCM 15138^T, Microcella alkaliphila DSM 18851^T and Microcella putealis DSM 19627^T within the radiation enclosing members of the family Microbacteriaceae. All pairwise percentage of conserved proteins between strain WY83^T and the closely related phylogenetic neighbors were greater than 65%. The average nucleotide identity and in silico DNA–DNA hybridization values were both below the thresholds used for the delineation of a new species. On the basis of the evidence presented, strains WY83^T, Y. alkaliphila JCM 15138^T, C. frigidaquae JCM 14730^T, M. alkaliphila DSM 18851^T and M. putealis DSM 19627^T should belong to different species of the same genus. Strain WY83^T represents a novel species of the genus Microcella, for which the name Microcella flavibacter sp. nov. is proposed. The type strain is WY83^T (=?KCTC 39637^T?=?MCCC 1A07099^T). Furthermore, Chryseoglobus frigidaquae, Chryseoglobus indicus, and Yonghaparkia alkaliphila were reclassified as Microcella frigidaquae comb. nov., Microcella indica nom. nov., and Microcella alkalica nom. nov., respectively.

一株牛源阿卡斑病毒的分离鉴定

阿卡斑病毒(Akabane virus,AKV)是能引起牛、绵羊、山羊流产、早产、新生胎儿畸形的虫媒性RNA病毒。为了解家畜虫媒病毒在我国西南边境地区的分布和流行情况,本研究对中缅边境西盟县的52份牛抗凝血和140份血清(牛70份、羊70份)中的蓝舌病病毒(Bluetongue virus,BTV)、鹿流行性出血热病毒(Epizootic hemorrhagic disease virus,EHDV)、AKV等虫媒病毒进行检测与分离,通过ELISA及qRT-PCR方法检测病毒,通过核酸阳性抗凝血接种BHK细胞传代以分离病毒,通过设计特异性引物,扩增分离毒株S基因721bp片段及M基因816bp片段,通过克隆测序及中和试验以鉴定病毒,最终从38号牛的抗凝血中分离到一株AKV,TCID50为10-3.5/0.1mL,经比对,分离株S片段与日本KS-2/Mo/06毒株亲缘关系最近,核苷酸同源性为97.66%,M片段与中国DHL10M110毒株亲缘关系最近,核苷酸同源性为96.56%。本研究首次报告了从云南边境地区牛群中分离到AKV,证实了西南边境存在AKV的流行,为AKV在我国的流行病学和边境地区疫病风险防控提供了重要参考及有力依据。
