作者 金美松 王浩 殷丽 《中外食品工业》 2024年第5期28-30,共3页
本文旨在全面分析细菌性食物中毒的病原菌种类、特点及对策。首先,文章概述了细菌性食物中毒的定义和背景,强调了其公共卫生重要性。文章进一步分析了病原菌的生物学特性、污染途径、传播方式以及引起的临床症状和病程。在此基础上,提... 本文旨在全面分析细菌性食物中毒的病原菌种类、特点及对策。首先,文章概述了细菌性食物中毒的定义和背景,强调了其公共卫生重要性。文章进一步分析了病原菌的生物学特性、污染途径、传播方式以及引起的临床症状和病程。在此基础上,提出了针对性的预防策略、早期检测与诊断方法、治疗措施以及康复期管理建议。通过本文的研究,我们期望能够增强公众对细菌性食物中毒的认识,增强食品安全意识,共同构建更加安全、健康的食品环境。 展开更多

We evaluated the immune response to infection with a pathogen in large yellow croaker(Pseudosciaena crocea Richardson).The fish were given an intraperitoneal(i.p.) injection of Vibrio parahaemolyticus or sterile sea water(control).We collected blood sera from the fish 0.17,1,2,4,8,12,or 16 d after injection(dpi).We measured tyrosinase activity and the concentrations of lysozyme,NOS,and antibodies.Serum tyrosinase activity was significantly higher at 0.17 and 4 dpi than in the control group,and peaked at 8 dpi.Lysozyme activity was significantly higher at 2 and 12 dpi than in the control group,but lower at 16 dpi.There is no statistical difference in the level of nitric oxides synthase(NOS) activity or antibodies between the control and injection groups.This is the first report of the tyrosinase activity in the serum of large yellow croaker.Our results indicate that tyrosinase plays an important role in the immediate immune defense against V.parahaemolyticus in large yellow croaker.Tyrosinase is a candidate parameter for investigation of fish innate immune defense. 展开更多
