The Animal Plant Health Agency (APHA) is set to begin using a new PCR test which would be automatically applied to the tissue samples collected at post mortem in prescribed scenarios to detect the bacterium that causes bovine TB
Other acid fast microorganisms, especially the Non- Tuberculous Mycobacteria (NTM) can also result in AFS positive smear hence, there is a high preponderance of false-positivity for TB in smear tests. Infection with the NTM do not require medications specific for TB or airborne isolation ...
