Koch (figure 1.4)used the criteria proposed by his former teacher,Jacob Henle (1809–1885),to establish the relationship between Bacillus anthracis and anthrax,and published his findings in 1876.Koch injected healthy mice with material from diseased animals,and the mice became ill.After transferring anthrax by inoculation through a series of 20 mice,he incubated a piece of spleen containing the anthrax bacillus in beef serum.The bacilli grew,reproduced,and produced spores.When the isolated bacilli or spores were injected into mice,anthrax developed.His criteria for proving the causal relationship between a microorganism and a specific disease are known as Koch’s postulates and can be summarized as follows:
1.The microorganism must be present in every case of the disease but absent from healthy organisms.2.The suspected microorganism must be isolated and grown
in a pure culture.
3.The same disease must result when the isolated
microorganism is inoculated into a healthy host.
4.The same microorganism must be isolated again from the
diseased host.
Although Koch used the general approach described in the postulates
during his anthrax studies,he did not outline them fully
until his 1884 publication on the cause of tuberculosis .
Koch’s proof that Bacillus anthracis caused anthrax was independently
confirmed by Pasteur and his coworkers.They discovered
that after burial of dead animals,anthrax spores survived
and were brought to the surface by earthworms.Healthy animals
then ingested the spores and became ill.

这么长你才给5分!
科赫 (图 1.4) 用了标准─被他的前老师,男人名 Henle(1809-1885),计划建立杆菌 anthracis 和炭疽热之间的关系,而且在 1876 年公开他的调查结果.科赫从生病的动物为健康老鼠注射材料了,而且老鼠生病了.在经过一系列 20只老鼠转移接插芽的炭疽热之后,他抱了在牛肉浆液中包含炭疽热杆菌的一个脾脏.bacilli 成长,再生,而且生产了户外运动.当隔离的 bacilli 或户外运动被注入老鼠,炭疽热发展.他的标准求证一个微生物和一种特定的疾病之间的原因的关系即是科赫的假定而且能依下列各项被概述:
1.微生物一定存在于疾病的每个情形但是从健康 organisms.2 缺席.可疑的微生物一定被隔离而且生长
在纯粹的文化方面.
3.相同的疾病一定产生当这隔离的
微生物进入一个健康主人之内被接种.
4.相同的微生物一定再次被隔离从这
生病的宿主.
虽然科赫用了在假定中被描述的一般的方法
在他的炭疽热研究期间,他没有完全概略说明他们
直到在肺结核的因素方面的他的 1884 的出版.
被引起炭疽热的科赫的证明那一杆菌 anthracis 独立地
根据巴斯德和他的同事确认.他们发现
哪一在死动物的埋葬之后,炭疽菌芽孢幸存
而且被蚯蚓带给表面了.健康动物
然后摄取了户外运动而且生病了.
谁傻了冒了 人工翻译啊 扔有道去呗
科赫(图1.4)使用的标准提出了他过去的老师,雅各伯亨勒(1809–1885),建立关系的炭疽芽孢杆菌和炭疽,和他的调查结果发表在1876。科赫注健康小鼠材料从患病动物,和老鼠生病。炭疽接种后通过一系列的20只老鼠,他酝酿了一块脾脏含有炭疽杆菌在牛血清。细菌生长,繁殖,并产生孢子。当孤立杆菌或孢子注入小鼠发达,炭疽。他标准证明之间的因果关系的微生物和具体的疾病被称为科赫的假设,可归纳如下:

1。微生物必须出现在每一种情况下的疾病,但没有健康的有机体。2。疑似微生物必须孤立和发展
在纯培养。
3。同一种疾病的结果必须当孤立
微生物接种到健康的主机。
4。同一微生物必须被隔离,再从
宿主病。
虽然科赫用一般方法中所描述的假设
在他的炭疽研究,他并未说明他们充分
直到他的1884次出版事业的肺结核。
科赫的证明,炭疽杆菌引起炭疽是独立
证实了巴斯德和他的同事。他们发现
在埋葬死去的动物,炭疽孢子存活
并被带到表面的蚯蚓。动物健康
摄入的孢子和生病。
