那USP61这句话又怎么理解:
“For solid media, growth obtained must not differ by a factor greater than 2 from the calculated value for a standardized inoculum. For a freshly prepared inoculum, growth of the microorganisms comparable to that previously obtained with a previously tested and approved batch of medium occurs”
1、standardized inoculum中的菌浓度怎么确定?
2、previously tested and approved batch of medium occurs是不是就是对照培养基?

那USP61这句话又怎么理解:
“For solid media, growth obtained must not differ by a factor greater ...
previously tested and approved batch of medium occurs可以称之为对照培养基
但与中国所谓的对照培养基是不同的
这个有点像OOS调查中的对照样品
是指你之前用过的(经过证明或批准的)培养基
这种作法有点像一些包衣粉的颜色检查方法
standardized inoculum应该就是指以这种对照培养基计出的结果
