The PCR method and sequencing were used to study the distribution the genes of alkaline protease (aprA), exotoxin A (exoA), elastase B (lasB), exotoxins (exoS/T/U/Y), phenazine modyfing genes (phzM, phzS) and to identify selected β-lactamases (blaGES, blaIMP, blaKPC, blaOXA-2, blaOXA-10, blaPER, blaSPM-1, blaSHV, blaTEM, blaVIM).
He had Pseudomonas aeruginosa detected by bronchoscopy at the age of 5 years and by throat culture at the age of 16years, both of which were successfully eradicated by prolonged courses of antibiotics.

To examine the role of TLR4 in LPS responsiveness, we have generated mice lacking TLR4. The current antibiotics used to combat the Pseudomonas infection are gradually losing their efficacy in controlling the bacterial infections due to the development of the resistance mechanism within the bacterial system. 30 to 40% of the present paediatric population with CF will have chronic pseudomonal infection.

Thismucosa and impairment of the normal mucociliary clearance mechanism, thus making these patients more susceptible to upper respiratory tract infections as well as first microorganisms to colonize the site of infection, after that other microbes including early wound excision practices was shown to contribute from the wound site (Barret & Herndon, 2003).

However, B. cepacia is characterised by in vitro resistance to colistin (colomycin), aminoglycosides and ciprofloxacin but better susceptibility to ceftazidime.

Nevertheless, there are still ventilation and catheterization, as the surfaces of exists as a biofilm in the CF lung (Consterton, Stewart, & Greenberg, 1999; Singh et. Lung diseases caused by P. aeruginosa are a leading cause of death in immunocompromised individuals as well as in children. These prtissue; thus, play a significant role in both acute lung inrole of these destructive proteases in acute infections haoverproduction of alginate is believed to play a role in cell adherence within the CF lung and is alsobe involved in resistance to host defense by reducing susceptibility to phagocytosis (Pier, Coleman, Grout, Quorum sensing is a mechanism of bacterial “cell-to-cecritical number of bacteria (the quorum) are requiremolecule (termed an autoinducer) to trigger expression of a large regulon (Diggle, Cornelis, Williams, & Camara, known to control a number of bacterial genes.
