      Johnsen, Pål jarle; Townsend, JP; Bøhn, Thomas; Simonsen, Gunnar Skov; Sundsfjord, arnfinn; Nielsen, Kaare Magne (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      To estimate the relative fitness differences between glycopeptide-resistant Enterococcus faecium (GREF) and glycopeptide-susceptible E. faecium (GSEF) from yearly surveillance data on the occurrence of GREF in Danish poultry farm environments. A population genetic model was adapted to retrospectively estimate the biological fitness cost of acquired resistance. Maximization of a likelihood function ...
