coli. The five ESBL-positive E. coli were clonal and all came from the same vulture population, proving their spread between animals. The ESBL phenotype was due to a blaCTX-M-15 gene located on the chromosome. Both ESBL- and AmpC-positive E. coli belonged to...
Extended-spectrum beta-lactamase-producing Escherichia coli (ESBL-EC) strains are emerging around the world as a source of resistance to 尾-lactam antibiotics such as ampicillin, cefotaxime, and ceftazidime. mcr-1 is a novel plasmid-medi... C Wu,Y Wang,X Shi,... - 《Emerging Microbes & ...
Since ESBL/pAmpC-producing E. coli seem not to persist on egg surfaces, there is no need to use CE solution ex ovo as a prevention method. The results indicate that other routes, such as for example transmission through fomites or horizontal gene transfer by other bacterial species, could ...
Previously, using a metagenomics approach, presence of several carbapenemase genes (blaVIM, blaIMP, blaNDM and blaOXA-48) was reported in the wastewaters of some of the same hospitals in Burkina Faso [27]. The resistance rate of our ESBL-producing E. coli and K. pneunomia isolates to ...
(89.13%) cases were related to females. As indicated in Table1, the patients mostly belonged to the age groups of 60–75 years old (283 cases, 20.11%) and 45–60 years old (254 cases, 18%). In both genders, the main infectious strain wasE. coli, while the proportion ofE. faecalis...

coli varied between 0 and 26 % [36]. The overall trends corresponded, with highest levels of ESBLs in E. coli found in Spain from poultry and from our sampled gulls. Further ESBL was lacking in Danish poultry as well as the gull samples. Although trends should be the same, resistance ...
The assay was performed to detect the ESBLs: blaTEM, blaSHV, blaOXA and blaCTX-M using a CTX-M-15 producing strain of Escherichia coli as a positive control. All 90 samples assessed for ESBLs were negative. However these results should be considered inconclusive, as different factors such ...
