The present study is conducted to in restigate the bacteria Pseudomonas aeruginosa, the impact of ultraviolet on the bacterial isolates under study and the resistance of these isolates to ultraviolet are studied in comparison to two standard isolates ( E . coli and Staphylococcus aureus ) which are considered sensitive to ultraviolet . The natures of the resistance of the isolates, under study, are also being investigated against the different antibiotics. The isolates are subjected to a test to examine their sensitivity to (12) types of antibiotics used routinely in the treatment of various infection of these bacteria. They are (streptomycin , cephalothin ,Gentamycin , cefotaxime ,nitrofurantion ,ampicillin, amoxicillin, rifampin, lincomycin, tetracycline, erythromycin and ciprofloxacin ).The lowest concentration installer ( MIC ) is also testified in accordance with six types of antibiotics (streptomycin, cefotaxime , rifampin , nitrofurantion , Gentamycin , amoxicillin ).The biologic effectiveness of the overlap between the bacterial isolates , under study, is examined against four bacteria (klebseilla pneumonia , Staphylococcus aureus , Enterobacter , Proteus ) The result of using the ultraviolet with different wavelength show the ability of the five local isolates used to resistance of ultraviolet reaching (180 s.) in comparison to the isolates E.coli and staph. aureus in which the ratio of killing is %100 at a time of exposing 40 , 60 sec. respectively. The results indicated that the five local bacterial isolates have high resistance to the most tested antibiotics, It is shouted that all of them have resistance to (erythromycin , tetracycline , lincomycin , Gentamycin ) but they are sensitive towards antibiotic streptomycin . as for the other antibiotics , over can find that the isolates are varied of them for being resisting or sensitive towards them .The results of testing the inhabited effectiveness of the five bacterial isolates towards some other bacterial isolates show the efficiency of the five local isolates in the inhabitation of growth of the five studied bacterial isolates.

Study on the isolation and identifications of bacteria associated with the root of legumes were conducted using Spread Plate Technique. The frequencies of occurrences of the bacteria isolate showed that a total of sixteen (16) bacteria belonging to three genera and four species were isolated from the leguminous plants. Maximum number recovered from sample collected from the root of groundnut was seven (7) followed by Soya bean with five (5) while Pea recorded the least number of four (4). Role of Bacillus subtilis in the soil around the leguminous plant was the highest, which covered about 37.50% of the total isolates. Other bacteria that were also isolated from the soil around the legumes root include Bacillus cereus and Staphylococcus aureus which covered about four (4) each representing 25.0% of the total isolates while Pseudomonas aeruginosa recorded the least value of 12.50%. The bacteria isolated from the root of the legumes were not significantly different (P < 0.05). The bacteria have Nitrogen-fixing potential, having isolated from three leguminous plants which include Soya bean, Groundnut and Pea.

Definitive Role

A number of biologically active complexes of cobalt(II) and nickel(II) with pyrazinedicarboxaimido derived thienyl and furanyl compounds having the same metal ion but different anions such as sulphate, nitrate, oxalate and acetate have been synthesized and characterized on the basis of their physical, spectral and analytical data. In order to evaluate the role of anions on their antibacterial properties, these ligands and their synthesized metal complexes with various anions have been screened against bacterial species Escherichia coil,Pseudomonas aeruginosa and Staphylococcus aureus. The title studies have proved a definitive role of anions in increasing the antibacterial properties.
