Pseudomonas aeruginosa, taxiformis Asparagopsis , Antibiotic


Pseudomonas aeruginosa has been to possess a unique level of resistance to most antibiotics, therefore made in the list of types to cause infections in Libyan hospitals. This study was conducted to test the sensitivity of three P.aeruginosa isolates from different infections: infection tract urinary (U), Wound infection (W), Diarrhoea (D), to aqueous and ethanol extracts of Asparagopsis taxiformis at a concentration of (50, 100) mg/ml,  compared with Neomycin and Gentamycin. The results showed the sensitivity of all P.aeruginosa isolates to A.taxiformis extracts, superiority is observed of ethanol extract at a concentration of 100 mg/ml on antibiotics and aqueous extract. P.aeruginosa (U) isolates were the most sensitive to extracts, while P.aeruginosa (W) isolates were the most resistant to extracts and antibiotics. The results also showed a resistance of all isolates to gentamycin compared to neomycin. Data in this study indicated to possibility use of Asparagopsis taxiformis could be a valid alternative for bio-control of Pseudomonas aeruginosa.
