Abstract: From the introduction of Mycoplasma bovis (M. bovis) into Ireland 25 years ago it has become an endemic pathogen with 30-45% of dairy herds currently exposed. Clinical signs include respiratory disease, polyarthritis and mastitis. There has been an increase in reported dairy outbreaks in the last five years possibly associated with national dairy herd expansion but also possibly confounded by increased awareness. M. bovis was detected in Australia in 1970. Between 1970 and 2006 there are no published reports of M. bovis associated disease. In 2006 it emerged as a cause of disease on dairy farms in New South Wales. Initially disease was observed predominantly on larger dairy farms. The disease has now become endemic in all dairy regions of Australia.
