A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

New aspects of the evolution of bacterial antibiotic resistance are discussed. Dissemination of antibiotic resistance appears to be unlimited since resistance genes from Gram-positive cocci have been detected in Gram negative bacteria. This suggests the occurrence of heterogramic genetic transfers between these phylogenetically distinct organisms. New characters of resistance to beta-lactam antibiotics in enterobacteria result from the apparition of mutant of the TEM-1 and TEM-2 penicillinases. Mutations that confer the capacity to hydrolyze the third generation cephalosporins are located in the active site of the enzymes.
