• Five novel strains of Serratia fonticola that produce FONA, a minor extended-spectrum beta-lactamase (ESBL), were isolated during routine surveillance of ESBL-producing Enterobacteriaceae in imported chicken meat in Japan in 2017 and 2018. These strains exhibited a clear ESBL phenotype in susceptibility tests carried out in the presence of clavulanic acid; however, all strains tested negative in a multiplex polymerase chain reaction assay used to detect TEM, SHV, and CTX-M β-lactamase genes. After identification of the bacterial species as S. fonticola, full length blaFONA genes were amplified and the DNA sequences were determined. The blaFONA genes from all 5 strains were different from those previously reported (blaFONA-1 to blaFONA-6); they clustered close to one another but were distinct from previously reported blaFONA genes in a phylogenic analysis based on amino acid sequences.
