Abstract
Two Klebsiella pneumoniae isolates of the same strain, identified in Poland, produced either TEM-47 or TEM-68, which differed by the Arg275Leu substitution. They harbored a few virulence factors, including an iron-chelating factor and capsule overproduction, suggesting that these factors were sufficient to enhance their nosocomial potency. TEM-68 and TEM-47 had similar enzymatic activities, but TEM-68 was less susceptible to inhibitors than TEM-47. These results confirm the role of the Arg275Leu substitution in the evolution of TEM enzymes.Entities:
