MRSA in animals and humans: occurrence and control

Methicillin-resistant Staphylococcus aureus
(MRSA) is an important causative agent of nosocomial infections. Animals can play a role in the transmission of MRSA to humans. In 2003, a livestock
associated variant of MRSA (LA-MRSA) was found
in livestock, and therewith animals became more
important as a reservoir for MRSA infections. In
this paper we will give a short overview on the occurrence in animals – especially livestock – and humans of both the human associated MRSA and the
LA-MRSA. Furthermore, the risk factors for transmission and colonisation of animals and humans by
animals will be discussed. Reduction of transmission of MRSA-infections in animals should focus on
the prudent use of antimicrobials and consistent
application of hygienic measures. Moreover, the
structure of livestock husbandry must change thoroughly, so that the transmission of infections is reduced. Selected future research questions to give
more insight into the measures for prevention will
be presented.
