ABSTRACT
The sequence type 131 (ST131)-
H
30 clone is responsible for a significant proportion of multidrug-resistant extraintestinal
Escherichia coli
infections. Recently, the C1-M27 clade of ST131-
H
30, associated with
bla
CTX-M-27
, has emerged. The complete genome sequence of
E. coli
isolate 81009 belonging to this clone, previously used during the development of ST131-specific monoclonal antibodies, is reported here.
