The cocci either lays dormant in their lungs or the infection kills them.

球孢子要么潜伏在它们肺部，要么使它们被感染致死。

In individuals with a normal immune system, fungi are a rare cause of pneumonia and often it's regional - for example, there's Coccidioidomycosis in California and the Southwest which you can remember because there's a " C" in both cocci and california.

在正常免疫系统个体中，真很少引起肺炎，且般是地区性，例如在美国加利福尼亚和西南部有肺孢子病，可以通过在cocci球和california加州中都有个“C”来记忆。

We can use this to differentiate Staph saprophyticus from other gram positive cocci, like streptococci and enterococci, which are catalase negative.

我们可以利特性来区分腐生葡萄球和其他革兰氏阳性球，如链球和肠球类过氧氢酶阴性。

Additionally, the cell wall helps maintain their shape: the round-shaped bacteria are called cocci, the rod-shaped ones are called bacilli, spiral-shaped ones are spirilla, and sometimes the same bacteria can have multiple forms in which case they're called pleomorphic.

此外，胞壁有助于保持其形状：圆形称为球，棒状叫做杆，螺旋形是螺旋，有些具有不同形态，因此它们被称为多形。

Ultimately, cocci's spread could be thanks to all of these factors combined but there are still tons of unresolved questions.

最终，球传播可能要归功于所有些因素结合，但仍有大量未解决问题。

And finding cocci in the soil at all has proven difficult.

事实证明，在土壤中找到球孢子是很困难。

This doesn't happen with urease negative Gram-positive cocci, like Streptococcus pneumoniae or Enterococcus faecalis.

现象在脲酶阴性革兰氏阳性中就不会发生，如肺炎链球或粪肠球。

One study estimates that cocci's range could more than double by 2095… due to increasing arid conditions across the US.

项研究估计，由于美国各地日益干旱环境，到 2095 年，球范围可能会增加倍以上。

When they die, cocci spread right back into the soil and the system starts again.

当它们死亡时，球孢子会传播回土壤中，个感染系统就又开始了。

If this is the case, then the more desert rodents living and dying, the more likely cocci can move through the soil.

如果是样话，那么越多沙漠啮齿动物生存和死亡，就越有可能通过土壤传播球孢子。

Let's start with some bizarre features of cocci itself.

让我们从球孢子本身些奇怪特征开始。

But we still don't know if this is actually even happening… because of how little we understand about cocci itself.

但我们仍然不知道是否真发生了，因为我们对球本身知之甚少。

When the rodent dies, cocci is released back into the soil and morphs back into its environmental form where it waits to be kicked up and inhaled by some other host.

当啮齿动物死亡时，球孢子被释放回土壤中，并变形成其环境形式，等待被其他宿主踢起并吸入。

The infection caused by cocci goes by many names.

由球孢子引起感染有很多名字。

Cocci is typically found in the soil in the southwestern US parts of Mexico, Central, and South America.

球通常存在于美国西南部、墨西哥、中美洲和南美洲土壤中。

What we do know is that the US is getting warmer and that on its own could expand cocci's range potentially making more people sick.

我们所知道是，美国正在变暖，可能会扩大球孢子生长范围，可能会让更多人生病。

And while most fungi eat dead or decaying material, cocci doesn't always wait for an animal to die before it starts digesting them from the inside out.

虽然大多数真都吃死亡或腐烂物质，但球孢子并不总是等到动物死亡后才开始从内到外消它们。

When the soil is disturbed like when dust storms sweep through the west or when construction workers begin digging a foundation… cocci releases spores into the air where unsuspecting mammals breathe them in.

当土壤受到扰动时，比如沙尘暴席卷西部，或者建筑工人开始挖掘地基时，球会将孢子释放到空气中，毫无戒备哺乳动物会将它们吸入。

Cocci isn't picky about what kind of lungs it's settling in.

球孢子并不挑剔它在什么样肺里定居。

And so maybe that's cocci's strategy.

也许就是球孢子策略。
