"Why don't they ....
..... use the same technique for badgers that we use in hospitals, to distinguish between patients with M .tuberculosis and M. bovis ?" So said a TB specialist, whose expertise lies in treating human patients for tuberculosis.
And that 'technique' is what?
Er ... PCR (Polymerase Chain Reaction) with a reported specificity to M. bovis of 98 per cent, and that two percent difference usually because of bad sampling techniques, the man said.
It is worth noting that these samples enter the laboratory with an M. tuberculosis complex tag, thus still further underplaying the role of M. bovis in human beings. The different drug regimes for each strain, paint a different picture.
(More on this story as it pads out.)
