Pseudomonas stutzeri is ubiquitous in hospital environments and it is an opportunistic but rare pathogen. It has been reported to cause bacteraemia meningitis pneumonia and osteomyelitis. This species was susceptible to a wide range of antibiotics including ampicillin tetracycline streptomycin nalidixic acid neomycin kanamycin polymyxin and gentamicin. The emergence of poly antimicrobial resistant strains of hospital pathogens has also presented a challenge in the provision of good quality inpatient care. At the global level people have understood the bad effect of antibiotics and they are now shifting over to natural products. Therefore it is of great interest to carry out a screening of these plants in order to validate their use in folk medicine and to reveal the active principle by isolation and characterisation of their constituents. The aim of this research is to Characterized the outer membrane protein of Pseudomonas stutzeri and investigasting the antibacterial effect of antibiotics and the methanol acetone and hexane extract of Piper betle leaves. SDS-PAGE electrophoresis was used in this research to isolate protein based on the molecular weight. Microdilution was used to determine the MIC and MBC of antibiotics and Piper betle leaves extracts. The extracts was used 3 solvents methanol aceton and hexane. Tetracycline Gentamycin Kanamycin and Penicillin was used. The Quantitative assay of outer membrane protein of Pseudomonas stuzeri s protein extractions showed concentration range 1.78 Mg/ml-2.06 Mg/ml. Meanwhile the Quantitative assay showed 13 bands protein from SDS-PAGE extraction. The bands protein are 127.8 kDa 107.9 kDA 91.2 kDa 81.5 kDa 68.8 kDa 54.9 kDa 49. 1 kDa 43. 8 kDa 39.2 kDa 33.1 kDa 24.9 kDa 16.8 kDa 14.2 kDa. MIC values were determined by two-fold serial dilution microplate bioassay and indicating growth with tetrazolium violet. MBC valus were determined by streaked the MIC from microplate to lactos agar and incubated in 24 hours.Piper betle L Acetone Extracts was the most active with average MIC value for Pseudomonas spp ( 31 25 956 g/ml) followed by Piper betle L Methanol Extracts with values 62 5 956 g/ml and Piper betle L Hexane Extracts with values 125 956 g/ml. for the Antibiotics Gentamycin was the most sensitive for Pseudomonas spp with values 0.048838 ug/ml followed by Kanamycin with values 12 5 956 g/ml Tetracycline and Penicilin showed that Pseudomonas spp is resistantance to those antibiotics.
