| Summary, etc. | CF is a genetically recessive disease marked by frequent, chronic lung infections that impair lung function and cause early death. There are limited published data on microbiological surveillance of CF patients from Middle East including Egypt. Some bacterial species colonizing the airways have recently become resistant to routine antimicrobial therapy. This resistance is attributed mainly to the formation of biofilm matrices, offering physical and electrostatic protection from antimicrobials, host defences and other environmental stressors.<br/><br/>The present study was conducted to identify the bacteria colonizing the airways among a cohort of Egyptian children with CF. Additionally, antimicrobial susceptibility and biofilm formation capacity of the isolated bacteria were assessed.<br/><br/>In the current study, A total of 43 bacteria were isolated from 34 respiratory samples from Egyptian pediatric patients with CF sputum specimens, Identification of the isolates was done according to colony morphology and the conventional microbiological standard tests. Antibiotic susceptibility testing was performed using Kirby–Bauer disc diffusion method. Biofilm formation of isolated pathogens were performed by microtiter plate assay.<br/><br/>In the present study, the most frequently isolated microorganisms were S. aureus (51.2%) followed by P. aeruginosa (34.9%). Other less prevalent bacterial isolates included E. coli, Klebsiella spp., and Acinetobacter spp. (4.7% each). Regarding antibiotic susceptibility profile, S. aureus demonstrated the greatest resistance to penicillin and cefoxitin, with resistance rates of 95.5% and 81.8% respectively. followed with Erythromycin and tetracycline, with resistance rates of 68.2% and 45.5% respectively. Alarmingly, a high prevalence of MRSA was<br/> <br/>observed among our tested isolates (81.8% of S. aureus isolates). Among P. aeruginosa isolates, cefepime and imipenem exhibited the highest resistance rates (26.7% each), followed by tobramycin (20%). All isolated pathogens produce biofilm with varying degrees. Among them 50% of S. aureus and 66.7% of P. aeruginosa were strong biofilm producers.<br/><br/>Our findings indicate a significantly higher prevalence of S. aureus chronic colonization among our CF patients. Meanwhile chronic colonization with P. aeruginosa was less prevalent. Unfortunately, there was a high prevalence of MRSA and biofilm formation among our isolated bacteria. Implementing strict preventive measures and infection control can help prevent MRSA-related exacerbations in these patients.<br/> |
