Objectives : The aim of this work was to determine the plasmid replicon profiles of a collection of  bla  CTX-M-1 -positive enterobacterial strains. The isolates originated from chicken in the production pyramid, healthy food-producing animals at slaughter (chicken, calves, and pigs), chicken retail meat, environmental isolates originating from water bodies, and isolates from humans. A selection of IncI and IncN plasmids were characterized by multilocus sequence typing in order to determine their epidemiological relatedness.   Methods : Transconjugants of 74  bla  CTX-M-1 -positive isolates were analyzed by PCR-based replicon typing and by PCR-based plasmid multilocus sequence typing.   Results : The incompatibility groups detected among the  bla  CTX-M-1 -harboring plasmids included IncI1, IncN, IncHI1B, IncF, IncFIIS, IncFIB, and IncB/O, with plasmid lineage IncI1/ST3 predominating in isolates from chicken and from humans. Lineage IncN/ST1 was detected mainly in isolates from pigs. For the first time,  bla  CTX-M-1  genes encoded on IncHI1 plasmids were detected in isolates from cattle and from water bodies.   Conclusions : This study identifies plasmid lineages that are contributing to the dissemination of  bla  CTX-M-1  genes in the food chain, the environment, and humans.
