摘要:

为准确诊断贵州某蜂场发生的细菌性中蜂疾病,并提供防制方案,本试验进行了细菌分离纯化、形态学观察、生化试验,应用细菌16S rRNA基因通用引物进行基因扩增测序,测序结果在NCBI上进行比对分析,选取同源性较高的5个属的30株细菌的16S rRNA序列进行同源性分析并构建系统进化树,并对该分离菌进行动物回归试验和药敏试验。结果显示,分离菌为革兰氏阴性短杆菌,生化试验初步鉴定为蜂房哈夫尼菌;16S rRNA序列与哈夫尼杆菌属同源性最高,在97.0%~99.6%之间;遗传进化树表明,分离菌在哈夫尼菌菌属这一分支;动物回归试验显示,分离菌对中蜂有一定致病性,表明该蜂场受到蜂房哈夫尼菌感染,造成了蜜蜂的副伤寒;药敏试验结果表明,分离菌对青霉素、红霉素、克林霉素等耐药,对阿米卡星、复方新诺明、氧氟沙星等敏感。本试验结果为中蜂感染蜂房哈夫尼菌病的研究提供了一定参考,并能对蜂场提供合理用药意见。

Abstract:

For the diagnosis,prevention and treatment of Apis cerana's bacterial disease in Guizhou,a pathogen was identified in this paper by isolation and purification,morphological observation and biochemical test.The bacterial 16S rRNA gene universal primers were used for amplification and sequencing.The results of the sequencing were analyzed on NCBI.16S rRNA sequences of 30 bacteria of 5 genera with high homology were selected to analyze the nucleotide homology and construct the phylogenetic tree,and animal regression test and drug sensitivity test of the isolate were carried out.The results showed that the isolate was short gram-negative bacilli,and the biochemical tests were initially identified as Hafnia alvei.16S rRNA sequences shared the highest homology with Hafnia,ranging from 97.0% to 99.6%.The phylogenetic tree indicated that the isolate belonged to the branch of Hafnia.The animal regression test showed that the isolate had some pathogenicity to Apis cerana,indicating that the bees were infected by Hafnia alvei.Antibiotic sensitive test showed that the isolate was resistant to penicillin,erythromycin and clindamycin,and was sensitive to amikacin,sulfamethoxazole and ofloxacin.The results of this study provided a reference for the study of honeybee Hafnia infection in Apis cerana and provided reasonable drug advice for the bee farms.

Key words: Apis cerana; Hafnia alvei; 16S rRNA; isolation and identification
