- A selection of plasmid-mediated AmpC-producing Escherichia coli isolates carrying blaCMY-2 from Swedish broilers were characterized to establish their relatedness to and a possible overlap with human clinical E. coli isolates. The results showed diversity among the E. coli isolated from broilers, indicating that the spread in the population was not due to one strain. However, only one type of plasmid belonging to replicon type incK was identified. Furthermore, there were no indications of spread of blaCMY-2 E. coli isolates from broilers to human clinical settings, although Swedish broilers may be a source of blaCMY-2 and/or the plasmid carrying blaCMY-2 .

- The aim of this study was to investigate the prevalence of extended-spectrum beta-lactamase (ESBL)-producing bacteria in patients at various hospital wards and in a group of relatively healthy volunteers, in order to obtain greater knowledge on how common these bacterial strains are in hospital settings and in the general community. Participants (n = 427) were enrolled at a University Hospital and at Primary Health Care Units (PHCUs) in Sweden in 2008 and 2010. The participants provided rectal swabs, which were tested for the occurrence of ESBL-producing bacteria. Positive samples were analysed with polymerase chain reaction (PCR) methods for bacterial strain typing and ESBL phylogroups. In 2008, the prevalence was 2.1% (2/96) in PHCU subjects and 1.8% (2/113) in hospital patients. In 2010, the prevalence was 3.0% (3/100) in PHCU subjects and 6.8% (8/118) in hospital patients. The dominating phylogroups were CTX-M-1 and CTX-M-9. All ESBL-positive isolates were Escherichia coli. We found a higher prevalence of ESBL faecal carriage than expected, both in the hospital setting and in the PHCU group.
