摘要
为了鉴定中华鳖"腐皮、疖疮"并发症的病原菌种类,对已呈明显发病症状且频死的20个、体重在100～1 000 g之间的中华鳖病样进行了病原菌的分离鉴定,经细菌组织涂片、分离培养与纯化、生理生化特性鉴定和人工感染试验证实,主要致病菌为嗜水气单胞菌(Aeromonas hydrophila)和洛菲不动杆菌(Acinetobacter lwoffi).药敏试验结果表明,两种病原菌对很多抗生素均存在不同程度的耐药性,而对美洛培南(Meropenem)、复方新诺明(Trimethoprim/Sulfa)等高度敏感,可作为防治该病的首选药物.
In order to identify the pathogenic species on complications of ＂skinrotting＂ disease and furunculosis disease, an isolation and identification test of pathogenic bacteria experiment from twenty symptoms and dying softshelled with weight between 100~1 000 g were conducted. And the main pathogens were verified to be Aeromonas hydrophila and Acinetobacter lwoffi by bacterial organizations smear, cultivation and purification, physiological and biochemical characterization and artificial infection. The drugsensitivity tests showed that the two pathogens existed different degrees of resistance to many antibiotics, except Meropenem and Trimethoprim/Sulfa, which were highly sensitive to the two pathogens and could be used as the preferred drug to cure the complications.
