First description of CTX-M-15-producing Klebsiella pneumoniae in Turkey.

315 than where total inhibition zones had formed. The important observation to make is that, outside of the inhibition zone, the inoculated cells multiplied to form visible colonies despite being in the triclosan vapour for up to 72 h at 22°C. This is entirely in accord with zone theory and, of course, everyday experience with diffusion susceptibility tests. It is unlikely therefore that at ambient temperatures perishable foods, in a triclosan-impregnated lunch box, would keep any better than food in a plain plastic box. The debate remains open as to whether the use of these products might also contribute to the emergence of clinically important resistance.4
