Way‚ Tehran‚ Iran Correspondence: * rasooli@shahed.ac.ir ABSTRACT Preservative agents are required to ensure that manufactured foods remain safe and unspoiled. Antimicrobial properties of essential oils (EOs) reveal that Gram-positive bacteria are more vulnerable than Gram-negative bacteria. A number of EO components have been identified as effective antibacterials‚ e.g. carvacrol‚ thymol‚ eugenol‚ cinnamaldehyde and cinnamic acid‚ having minimum inhibitory concentrations (MICs) at higher dilutions

While this defense mechanisms remains prevalent in cystic fibrosis patients it appears to be compromised in that it allows the growth of Pseudomonas aeruginosa in airway mucus. The fact that people with cystic fibrosis are equally exposed to pathogens as any healthy person it remains a question as to why Pseudomonas aeruginosa has been successful at inhabiting and multiplying in the lungs of cystic fibrosis patients.

Vancomycin-resistant enterococci (VRE)? Vancomycin-resistant enterococci are enterococcus strains‚ such as Staphylococcus faecalis‚ now called Enterococcus faecalis that are resistant to the antibiotic vancomycin. Enterococci infections are the most common type acquired by hospitalised patients. Vancomycin was the last-line antibiotic for hospital treatment of serious methicillin-resistant staphylococcus aureus (MRSA) infections according to Collignon (2002‚ p. 327). These enterococci have become resistant
