Abstract
CC398 is a livestock-associated Staphylococcus aureus. However, it has also been isolated from humans with no
previous contact with livestock. A surveillance of methicillin-resistant S. aureus colonisation among children attending
public day care centres and hospitals in Niterói and Rio de Janeiro, Brazil, between 2011 and 2013, resulted in the
isolation of six cases of CC398 from individuals with no previous exposure to livestock. These isolates showed a high
frequency of the erm(C) gene (4/6, 66.7%) with induced resistance to clindamycin, and a relatively high frequency of
SEs and lukS/lukF genes. These results suggest the emergence of a non-LA-CC398 in Brazil.
