Tubercolosis followed humans out of Africa
PARIS (AFP) - One of the largest genetic investigations into the microbe which causes TB shows the germ followed early humans out of Africa at least 70,000 years ago, scientists said on Sunday.
In a parallel probe, investigators also said they had identified 39 new genes that drive dangerous drug resistance in this germ, Mycobacterium tuberculosis.
TB is one of the deadliest diseases in the medical lexicon. Untreated, it kills roughly half the people it infects.
Even today, in the era of advanced antibiotics, it causes between a million and two million deaths each year, mainly in developing countries.
