我国沿海致病性弧菌调查及抗生素敏感性分析

目的 了解我国福建沿海海水中致病性弧菌的分布情况及对21种抗生素的敏感性。方法 海水经增培养、细菌分离、进行细菌鉴定及药物敏感性试验。结果 102份海水共分离出弧菌科细菌3属17种159株，其中弧菌属142结果显示，157株致病性弧菌对亚胺增南、耐替米星、左氧沙星及头孢哌酮/舒巴四环素、氯霉素、替卡西林/克拉维酸的敏感率为90．45％—97．45％，对头孢唑啉和氨苄西林的敏感率为25．48％—27．39％。结论 此项研究对海水中弧菌所致疾病的预防、诊断和治疗都具有重要指导意义。     

Effects of seawater immersion combined with open abdominal injury on the expression of NF-κB,and IκBαof small intestine in rats

Objective To observe effects of seawater immersion combined with open abdominal injury on the expression of NF-κB,and IκBαas well as the change pattern in rats. Methods Ninety-one Wistar rats were randomly divided into 3 groups: the control group (n =7), the open abdominal injury group(n =42) and open abdominal injury combined with 1-hour seawater immersion group ( n =42). The expression of NF-κB,andIκBαin small intestine tissues was measured by Western blot and statistical analyses were also made in the study. Results The expression of NF-κB,in the seawater immersion combined with open abdominal injury group increased significantly 3 hours after injury, when compared with that of the open abdominal injury group(P<0. 05), whereas the expression of NF-κB, of the pure injury group was slightly lower than that of the control group, but no statistical differences could be seen between them(P>0.05). The change pattern in the expression of IκBαwas quite the opposite to that of NF-κB. Conclusions NF-κB seemed to be rapidly and persistently involved in the whole inflammatory response to trauma induced by opened abdominal injury and seawater immersion, when a comparison was made with the pure open abdominal injury group. Injuries for the rats in the open abdominal injury combined with seawater immersion group were serious, and the feedback mechanism for NF-κB was not established for quite a long time.
