BACKGROUNDBACKGROUND� Antibiotic resistance is recognised as one of the greatest public health
threats of the 21st century
� Common bacterial infections such as blood stream infection, wound infections, STIs,
bacterial pneumonia, neonatal infections, meningitis…
� Infections caused by resistant microorganisms often fail to respond to conventional
treatment, resulting in prolonged illness and greater risk of death.
� Gram-negative bacterial infections resistant to most available antibiotics are
spreading globally as illustrated by recent NDM-1 outbreak. spreading globally as illustrated by recent NDM-1 outbreak.
� Resistant gonorrhoea emerging as a big problem in many parts of the world.
� A high percentage of hospital-acquired infections are caused by highly resistant
bacteria such as methicillin-resistant Staphylococcus aureus (MRSA).
� Inappropriate and irrational use of antimicrobial medicines provides favorable conditions for resistant microorganisms to emerge, spread and persist.
