Du Cros said that it’s hard enough dealing with MDR-TB, let alone an even stronger strain of the bacteria that causes XDR-TB or extensively drug resistant tuberculosis.

Du Cros ， 理耐多结核病已经够难了，更不用导致广泛耐结核病广泛耐结核病的更强菌株了。

You may hear about MDR-TB or multi-drug resistant TB, or even XDR-TB which is extremely drug-resistant TB which are credibly hard-to-treat because they don't die in the presence of our usual antibiotics.

你可能听过MDR-TB，即多重抗TB，甚至是XDR-TB，即极度耐TB，极其难以治疗，因为它们并不能用我们普通的抗生素杀灭。
