细胞培养污染是指培养环境中侵入了对细胞生存有害的成分和造成细胞变异的异物。体外细胞培养污染可分为三类：物理性、化学性及生物性污染。

物理性污染：
物理性污染通过影响细胞培养体系中的生化成分，从而影响细胞的代谢。
物理性污染的来源：培养环境中的物理因素，如温度、放射线、振动、辐射（紫外线或荧光）会对细胞产生影响。
物理性污染的现象：细胞、培养液或其他培养试剂暴露在放射线、辐射或过冷过热的温度中，可以引起细胞代谢发生改变，如细胞同步化、细胞生长受抑制，甚至细胞死亡。
化学性污染
化学性污染是一些对细胞有毒性的或对细胞产生刺激的化学物质。
化学性污染的来源：
未纯化的物质、试剂、水、血清、生长辅助因子及储存试剂的容器都可能成为化学性污染的来源。细胞培养的必需养分（如氨基酸）若浓度超过了合理的范围，也会对细胞产生毒性。同样，不同细胞系在*培养条件下对血清和缓冲液的要求是不一样的，在培养中应严格控制。
化学性污染的现象：化学性污染同样会使细胞生长受抑制，甚至细胞死亡。
生物污染
生物污染包括比较容易发现的细菌、霉菌和酵母的污染，和较难发现的病毒、支原体和其他细胞的污染。
生物性污染的来源：
 取材不慎或处理不当
 空气尘埃
 消毒不严
 操作不当
 试剂尤其是血清污染
生物性污染的现象：
细菌：G+菌较多。
 真菌：霉菌较多。
 支原体：不易检测。
 病毒：由于病毒有种属特异性，所以病毒污染的概率比较小。

But half an hour later, her stomach began to discomfort and went back home to her stomach. After taking a few antidiarrheal drugs, still run the toilet. From more than eight in the evening to six in the second day in the morning, more than fifteen times have been pulled, and the body is extremely tired.

After the hospital diagnosis and the laboratory test, the original Miss Liu was eaten without washing the strawberry caused by acute gastroenteritis.

A tall, delicious strawberry,

Why is the consequences so serious after eating?

Zhou Guozao, the deputy chief physician of Xiamen Pu Pu hospital, introduced the seemingly clean strawberry. Because of the surface protruding particles, there are many tiny concave parts, which are easily attached to dust, bacteria and even pesticide residues. If cleaning is not clean, it may cause diarrhea.

And there's a more important reminder -

Children eat strawberries

May be infected with NOx virus!
Norovirus is a leading cause of acute nonbacterial gastroenteritis virus, also known as Norwalk virus. Norovirus infection may occur throughout the year, but it has the highest incidence in the cold season from November to February, so it is also known as "winter vomiting".

During this period of flu, norovirus is "run amuck".

Norovirus can pass through

The contact between people, food and water intake port communication

The main cause of infective diarrhea is as follows:

Nausea, vomiting, fever, abdominal pain and diarrhea

The incubation period is more than 24~48 hours
