Bovine mastitis

In the U.S.A. the S. aureus mastitis comprise a total of 10-12% of all clinical mastitis. It creates the yearly cost/loss of the $1.7 billion to the American dairy industry. Longitudinal studies of clinical mastitis caused by S. aureus detected in the milk of dairy cattle worldwide was 26% contaminated milk in Tanzania to 23% at Netherland as of the year 2000. Therefore we are facing the global problem. The worldwide number of dairy cows as of the year 2003 was more then 238 million. Another dairy animal, which is suffering with the same S. aureus mastitis problem, is the water buffalo. At the year of 2005 it was 130 million water buffalos living world wide, more then 60% of the animals in the Pakistan and India. 

The companion animals

The MRSA is emerging on the companion animals (dogs, cats and horses) as well as on swine herds through the whole word. The isolated MRSA strains are identical with the human MRSA strains. This problem, including a new MRSA strain ST 398 originally isolated from the swine herds and already isolated on the horses and human including kindergarten children, is representing another emerging challenge to the human and animal health.
