We isolated Shiga toxin-producingEscherichia coliO157:H7 strains resistant to third-generation cephalosporins. The resistant strains harboredblaCMY-2, a plasmid-mediated AmpC β-lactamase. Genotyping of isolates revealed the possible spread of this problematic bacterium. Results suggested the importance of the investigation and surveillance of enterobacteria with plasmids harboringblaCMY-2.

Abstract The aim of this study was to elucidate the epidemiology of third generation cephalosporin resistant Samonella isolates from pork of a slaughterhouse in China and the features of transferable elements carrying bla CTX-M genes. One hundred and twenty-six (7.3%) Salmonella isolates were identified; S. Derby and S. Rissen were the most two prevalent serotypes. Among these isolates 20 (15.8%) were resistant to third generation cephalosporins and nine of them carried bla CTX-M-27. S1-PFGE and replicon typing of bla CTX-M-27-carrying plasmids showed that seven were untypeable plasmids of about 104 Kb and two were IncP plasmids of about 300 Kb. Complete sequence analysis of one PBRT-untypeable plasmid showed it was a P1-like bateriophage, named SJ46, which contained a non-phage-associated region with several mobile elements, including Tn1721, ISEcp1B and IS903D. The other six 104 Kb PBRT-untypeable bla CTX-M-27-carrying plasmids also harboured the same phage-insertion region of SJ46 suggesting that they were the same P1-like bacteriophage. PFGE profiles of the parental strains revealed both potential vertical and horizontal spread of this P1-like bla CTX-M-27-containing element. Additionally, the representative gene of the P1 family bacteriophage, repL, was detected in 19.0% (24/126) of the isolates. This study indicated a potential role of P1-family bacteriophage in capture and spread of antimicrobial resistance in pathogens.

Ceftibuten dihydrate, one of the third-generation cephalosporin antibiotic is effectively used in curing several infectious diseases. The complexation of drug with metal may enhance the antibacterial activity. In this work, a new complex of ceftibuten dihydrate with Cu(II) was synthesized, characterized and antibacterial activity is reported. The in vitro test showed that the antibacterial activity of complex of ceftibuten was greatly enhanced against Staphylococcus aureus and Salmonella typhi.

ABSTRACTCharacterization of third-generation-cephalosporin-resistantKlebsiella pneumoniaeisolates originating mainly from one human hospital (n= 22) and one companion animal hospital (n= 25) in Bern (Switzerland) revealed the absence of epidemiological links between human and animal isolates. Human infections were not associated with the spread of any specific clone, while the majority of animal infections were due toK. pneumoniaesequence type 11 isolates producing plasmidic DHA AmpC. This clonal dissemination within the veterinary hospital emphasizes the need for effective infection control practices.
