Uncooked meats and cooked meat dishes stored at room temperature can build up massive bacterial populations in just hours.

在室温下储存的生肉和熟肉在短短几小时内就会有大量的细菌。

Dr Paz knew from past work that sheep with severe worm infestations tend to have abnormal bacterial populations in their faeces.

Paz博士从过去的工作中了解到，患有严重蠕虫感染的绵羊的粪便中往往细菌种群不正常。

This single microbe can make up 90% of the bacterial population in an infant's gut, and it loves to eat HMOs.

这种单一的微生物占婴儿肠道细菌总数的90%，它喜欢吃HMO。

The bacterial population in the mouth is diverse, and if the pH in the mouth starts to decrease, it alters the balance of power.

Sure, it might seem gross, but can you think of any other substance that can lubricate, keep your body clean, fight infection, and domesticate a teeming bacterial population?

黏液看起来的确挺恶心的，但你还知道有其他物质 可以像黏液这样润滑，能保持身体清洁，能对抗感染，还能驯服寄生的细菌群吗？

These differences were particularly notable in the small intestine, where the worms live, with resistant sheep having richer and more diverse bacterial populations in this part of the gut than vulnerable animals did.

这些差异在蠕虫生活的小肠中尤为明显，与易受感染的动物相比，抗蠕虫绵羊在肠道的这一部分拥有更丰富和更多样化的细菌种群。
