OBJECTIVE
To investigate a case of mass mortality of Garra rufa (G. rufa) from a fish hatchery farm in Slovakia.
METHODS
Causative bacterial agent was swabbing out of affected fish skin area and subsequently identified using commercial test system. Antibiotic susceptibility was determined by the disk diffusion method.
RESULTS
Infected G. rufa was characterized by abnormal swimming behaviour, bleeding of skin lesions and local haemorrhages. Despite of using recommended aquatic antibiotic treatment no improvement was achieved and Aeromonas sobria (A. sobria) was identified as a causative agent of fish mortality. Due to massive fish mortality, antibiotic susceptibility of pure isolated culture of A. sobria was evaluated employing eight antibiotics against human infections. A. sobria was resistant only against one antibiotic, namely ampicilin.
CONCLUSIONS
These results indicate that A. sobria can act as a primary pathogen of G. rufa and may be a potential risk factor for immunodeficient or immunoincompetent patients during the ichthyotherapy.
目的
调查斯洛伐克一家鱼类孵化场的红斑古B鱼大规模死亡病例。
方法
从受影响的鱼皮肤区域擦拭采集致病细菌病原体，随后使用商业检测系统进行鉴定。采用纸片扩散法测定抗生素敏感性。
结果
受感染的红斑古B鱼表现为异常游泳行为、皮肤损伤出血和局部出血。尽管使用了推荐的水产抗生素治疗，但病情并未改善，嗜水气单胞菌被鉴定为鱼类死亡的病原体。由于大量鱼类死亡，使用八种针对人类感染的抗生素评估了嗜水气单胞菌纯分离培养物的抗生素敏感性。嗜水气单胞菌仅对一种抗生素即氨苄西林耐药。
结论
这些结果表明，嗜水气单胞菌可作为红斑古B鱼的主要病原体，并且在鱼疗过程中可能是免疫缺陷或免疫功能不全患者的潜在危险因素。
