In the present study, the test of the susceptibility of the plant Bassia muricata L., through the effect of the extract of hot water on the bacteria (Pseudomonas aeruginosa). Where the plant was collected from Baghdad and different areas along the banks of the Tigris River. The histological sections of the stem were examined and studied. The stems of the young plant were characterized by thick Sclerenchyma. Soil samples were collected from different areas on the banks of the Tigris River after soil examination was isolated and diagnosed with Pseudomonas aeruginosa.
Results showed laboratory study, the hot water extract of Bassia muricata L. was highly effective in inhibiting the growth of Pseudomonas aeruginosa. The objectives of the study are the need to look for alternatives to antibiotics for diseases; given the risks posed by the use of antibiotics; the development of microbial resistance; and the inefficiency of traditional methods to control disease elimination. There is a need to encourage researchers to find plant alternatives and less toxicity, less toxic, less dangerous, and cheap and effective, not as polluting to the environment as possible, for this reason, this study of the effect of hot water for Bassia muricata L. extract on the growth of bacteria in the laboratory. This plant has been selected for its abundance as a wild plant prevalent in Baghdad. The main objective of this study is to use alternative medicines, which will be available, safe, and cheap instead of the high costs and somewhat harmful drugs.
