The structure of the macrolide efflux genetic assembly (mega) element, its genomic locations, and its association with other resistance determinants and genetic elements were investigated in 16 Streptococcus pneumoniae isolates carrying mef(E), of which 1 isolate also carried tet(M) and 4 isolates also carried tet(M) and erm(B). All isolates carried a mega element of similar size and structure ...
objectives : the aim of this study was to assess the effect of artificial accelerated aging (aaa) on color change of direct and indirect fiber-reinforced composite (frc) restorations. materials and methods: direct (z250) and indirect (gradia) composite resins were reinforced with glass (gf) and polyethylene fibers (pf) based on the manufacturers’ instructions. forty samples were fabricated and ...
