目的:了解亚丁湾海域海水主要理化特性、细菌种类及其对抗菌药物的敏感性。方法:采集亚丁湾海域不同地理位置海水样本;用自动生化分析仪测定海水主要理化指标;海水经增菌培养和细菌分离,对所分离细菌进行菌株鉴定及其对不同抗菌药物敏感性试验。结果:亚丁湾海域海水Na+、K+、Cl-和Ca2+离子含量分别为525.0±14.0、12.5±0.25、86.8±16.1和11.7±0.3 mmol/L;从8份不同地理位置海水水样中共分离和培养细菌菌株80株,均鉴定为斯氏假单胞菌;药敏实验分析表明该海域斯氏假单胞菌对头孢呋辛、头孢他啶、奈替米星和环丙沙星等18种临床常用抗菌药物均敏感。结论:亚丁湾海域海水理化性质和常见致病菌具有特殊性,对指导该海域从业人员健康保障和维护具有科学意义。
Objective: To understand the main physical and chemical characteristics of seawater in the Gulf of Aden, bacterial species and its sensitivity to antibacterial drugs. Methods: The seawater samples of different geographical locations in the Gulf of Aden were collected. The main physical and chemical indexes of seawater were determined by automatic biochemical analyzer. The seawater was identified by bacteria enrichment and bacterial isolation. The sensitivity of different bacteria to antibiotics was tested. Results: The contents of Na +, K +, Cl- and Ca2 + in seawater of the Gulf of Aden were 525.0 ± 14.0,12.5 ± 0.25,86.8 ± 16.1 and 11.7 ± 0.3 mmol / L, respectively. Separation and culture of eight samples from seawater samples of different geographical locations 80 bacterial strains were identified as Pasteurella multocida; drug susceptibility test analysis showed that Pseudomonas aeruginosa of the sea of cefuroxime, ceftazidime, netilmicin and ciprofloxacin 18 kinds of commonly used antibacterial Drugs are sensitive. Conclusion: The physical and chemical properties of seawater and the common pathogens in the Gulf of Aden are of particular significance. It is of scientific significance to guide the health protection and maintenance of practitioners in this area.
