(CTX-M-55) has been obtained by sequencing; and then combined transfer, primer extension, gene locus and removable elements annotation will be carried out to trace the source and transmission mode of the resistance gene; then enzymatic analysis will be done by means of the crystal structure ...
but some strains were resistant to aztreonam. ConclusionXicheng district of Beijing were mainly CTX-M- 14 subtype and the gene structure was stable. The strains carrying CTX-M- 14 ESBLs showed multidrug resistance.Key words:Shigella; extended spectrum beta-lactamases; CTX-M; drug resistanceThis ...

The gene cassette for transposase – CTX-M-1 β-lactamase – tryptophan synthase was integrated in the IncI1 conjugative transfer region of the plasmids with 13 different variants being identified. Fig. 3 summarizes the diversity of the resistance gene region, where an 8523 bp sequence of the ...
据有关报道,CTX-M型和TEM型或SHV型的同源性较低,仅为40%[2]。目前发现的的CTX-M型ESBLs种类超过107种,根据其氨基酸序列的差异(大于94%的相同序列认为是一个群,小于90%的相同序列认为是不同的群)分为5个群[3]:CTX-M-1 群包括 CTX-M-1、CTX-M-3、CTX-M-10、CTX-M-12、CTX-M-15、FEC-1、...
The distribution of CTX-M drug resistance genotypes were analyzed by PCR and gene sequencing. Different pH environment was established in vitro to evaluate the effect of pH on drug resistance of CTX-M resistant Escherichia coli. Results In 113 Escherichia coli strains, there were 68 ESBL-...
