Human-to-human transmission can spread bovine TB

Bovine TB can be spread by human-to-human contact, according to UK research.

The researchers conducted genetic fingerprinting of all TB cases occurring between 2001 and 2005 in central England.

Of the 20 cases identified as human Mycobacterium bovis infection, six were found to be genetically indistinguishable.

Four patients were found to possess factors predisposing to TB and one patient died from M bovis meningitis.

They concluded that person-to-person transmission had occurred because all patients were found to have common social links.
