金黄色葡萄球菌引起食物中毒的作用机制与其耐药性的研究进展

葡萄球菌广泛分布于自然界中,如空气、土壤、水以及物体的表面,在人和动物的皮肤表面部、鼻咽、肠道也常可发现葡萄球菌。大部分葡萄球菌是非致病菌,少数可引起人或动物致病,金黄色葡萄球菌（Staphylococcus aureus,金葡菌）即为最主要的致病性葡萄球菌。金葡菌是一种革兰氏阳性球菌,是医院感染常见的病原体之一,同时也是引起食品污染和细菌性食物中毒的一种重要细菌,其产生的毒素可使人中毒,带来非常严重的公共卫生负担。本文拟对金葡菌的病原与病理学特性,金葡菌与食物中毒,抗生素滥用与金葡菌耐药性等方面做简要综述。

Development of Staphylococcus Aureus in both Food-Borne Pathogen and Antibiotic Resistance

Staphylococci strains are widely distributed in nature,including air,soil,water and many other things,such as the skins of animals and human beings.Most of these organisms are non-pathogenic,however,some of them can also cause very severe dis-eases,of which,Staphylococcus aureus is the major one.Food samples contaminated by this organism will decay rapidly,in the mean time the a toxin named enterotoxin,which is produced by S.aureus,would result in severe food poisoning in human being and remains a leading reason for food-borne contamination.This study aims at giving a brief introduction to the development of S.aureus in the field of both food safety and antibiotic resistance.
