Objective: To estimate the contribution of livestock associated methicillin-resistant Staphylococcus aureus Sequence Type 398 (MRSA-ST398) to the burden of MRSA from humans in Europe in 2007.

Methods: A cross sectional survey was performed. In September 2008, a questionnaire was sent to 43 laboratories in 23 countries, with questions on general laboratory information, number of MRSA isolates and number of MRSA-ST398 isolates in 2007.

Preliminary results: As of December 2008, we have received the replies from 24 (56%) laboratories from 17 (74%) countries. Only results from the 20 laboratories that typed MRSA isolates are reported. This includes data from the following 15 countries: Austria, Belgium, Czech Republic, Denmark, Finland, Germany, Greece, Hungary, Iceland, Italy, Ireland, the Netherlands, Sweden, Switzerland and Turkey.

In total 7,770 MRSA isolates with typing results were reported and 113 (1.5%) were MRSA-ST398. Eight of the 15 countries reported MRSA-ST398. The proportion of MRSA-ST398 ranged from 0 to 11.9%. The countries with the highest proportion of MRSA-ST398 were the Netherlands (11.9%), Belgium (4.7%), Austria (2.7%) and Denmark (1.6%).

Preliminary conclusions: MRSA-ST398 has spread across Europe, but the proportion of such isolates generally remains low. The highest proportions were reported by the Netherlands, Belgium, Austria and Denmark. Three of these countries, i.e. the Netherlands, Belgium and Denmark, have the highest pig density per square kilometre among European countries.
