(Springer, 2015)
A series of fused and non-fused 1,2,4-triazole derivatives were prepared starting from ethyl 4-[1-(2-ethoxy-2-oxoethyl)-3-methyl-5-oxo-1,5-dihydro-4H-1,2,4-triazol-4-yl]benzoate. Firstly, both ethyl ester groups were ...
Distribution of beta-lactamase genes among carbapenem-resistant klebsiella pneumoniae strains isolated from patients in Turkey
(Korean Soc Laboratory Medicine, 2015)
Background: the emergence of carbapenem-resistant Klebsiella pneumoniae poses a serious problem to antibiotic management. We investigated the beta-lactamases in a group of carbapenem-resistant K. pneumoniae clinical isolates ...
