Broad-Host Dissemination of Plasmids Coharboring the fos Operon for Fructooligosaccharide Metabolism with Antibiotic Resistance Genes

Popis výsledku v původním jazyce

The fos operon encoding short-chain fructooligosaccharide (scFOS) utilization enables bacteria of the family Enterobacteriaceae to grow and be sustained in environments where they would struggle to survive. Despite several cases of the detection of the fos operon in isolates of avian and equine origins, its global distribution in bacterial genomes remains unknown. The presence of the plasmid-harbored fos operon among resistant bacteria may promote the spread of antibiotic resistance. A collection of 11,538 antimicrobial-resistant Enterobacteriaceae isolates from various sources was screened for the fosT gene encoding the scFOS transporter. Out of 307 fosT-positive isolates, 80% of them originated from sources not previously linked to fosT (humans, wastewater, and animals). The chromosomally harbored fos operon was detected in 163/237 isolates subjected to whole-genome sequencing. In the remaining 74 isolates, the operon was carried by plasmids. Further analyses focusing on the isolates with a plasmid-harbored fos operon showed that the operon was linked to various incompatibility (Inc) groups, including the IncHI1, IncF-type, IncK2, IncI1, and IncY families. Long-read sequencing of representative plasmids showed the colocalization of fos genes with antibiotic resistance genes (ARGs) in IncHI1 (containing a multidrug resistance region), IncK2 (bla(TEM-1A)), IncI1 [sul2 and tet(A)], and IncY [aadA5, dfrA17, sul2, and tet(A)] plasmids, while IncF-type plasmids had no ARGs but coharbored virulence-associated genes. Despite the differences in the locations and structures of the fos operons, all isolates except one were proven to utilize scFOSs. In this study, we show that the fos operon and its spread are not strictly bound to one group of plasmids, and therefore, it should not be overlooked.
