Ag-NPs have been recycled as an antiviral, antibacterial, antifungal and anti-inflammatory properties due to their physical, chemical & biological belongings. This study aims to biologically synthesize silver nano-particles using Burkholderiacepacia and investigate antibacterial action of nanoparticles only and in combination with ciprofloxacin against P. aeruginosaz,. Silver nanoparticles were formatted via reaction of silver nitrate (AgNO3) hooked on cell allowed supernatant of B. cepacia in attentions (1,2, 3, 4,5)Mm. Silver nitrate was castoff as a herald to silver nanoparticles. The first symptom of the bio-creation of silver nanoparticles is viatint variation of the response mixture from yellow to reddish brown. The best concentration of 4Mm was dogged based on the tint variation from yellow to reddish brown with the antimicrobial motion. Bio-creation nanoparticles with B. cepacia were first characterized using UV-visible spectrophotometry via which a signal absorption (420) nm was detected, beside to exhausting a scanning electron microscope (SEM) to perceive the proportions, form with circulation of nanoparticles. The spherical shape, heterogeneous distribution, and nanoparticle size ranged between (51-86nm), and the occurrence of Ag was analyzed via Energy fraction -x-ray Spectroscopy (EDS) inquiry. The average size of the Ag-NPs was dogged via X-ray measurement (XRD), fluctuated from (23-37nm). Ag-NPs presented Antimicrobial activity alongside P. Aeruginosa isolates. Furthermore, the Ag-NPs were also assessed to their increased anti-microbial activities with cipro- drug against P. aeruginosa. The antibiofilm activities of Ag-NPs alone or in combination with ciprofloxacin were besides examined. biofilm Creation is associated with resistance to anti-microbial reagents and to chronic bacterial pollutions, Ag-NPs showed anti biofilm activity against P. aeruginosa, the combination of Ag-NPs with ciprofloxacin in (2 concentrations) MIC and Sub MIC gave enhanced antibiofilm activity as related to Ag-NPs only beside to ciprofloxacin only.
