• PubMed Abstract: 
  

  The remarkable rise in multi-drug resistant Gram-negative bacterial pathogens is a major concern to the well being of humans as well as susceptible plants. In recent years, diseases associated with inflammation and septicemia have already become a global health issue. Therefore, there is a rising demand for the development of novel "super" antibiotics. In this context, antimicrobial peptides offer an attractive, alternate therapeutic solution to conventional antibiotics.
