Despite the decline in regular TB, drug resistant strains of the disease have worsened and spread here and globally.
Once she was infected, though, the disease became drug-resistant inside her body.

"But even if we upgraded those systems, the lack of a really effective vaccine, the lack of better and faster drugs that shorten treatment to a reasonable time and the lack of good drugs for treating resistant disease -- make it hard for any health care system to effectively deal with the disease, " he said.
In some small studies in India, a big portion of untreated or newly diagnosed patients were multi-drug-resistant, meaning they had picked up resistant forms of the disease.

For example, widespread failure in our handful of remaining major crops and animal breeds due to disease or pest outbreaks is a very real possibility: given that pest and pathogens are constantly evolving, a diverse gene pool is essential if we are to develop insect- and disease-resistant strains in the future.

That's bad enough with regular TB or with strains that are resistant to two or three mainline drugs used to treat the disease.
