The inhibitory effect of aquatic extracts of (Common mistletoe) on some bacterial isolates from different clinical cases

This study was conducted at the Iraqi University, College of Education, from 1/3/2021 to 1/6/2021, and included the collection of three clinical isolates of the bacterial species Staphylococcus aureus, Klebsiella pneumoniae and Acinetobacter baumannii, from swabs of wounds and burns, which were collected from the Hospital of Baghdad Medicine City. Where the bacterial samples were cultured on Macconkey agar medium to ensure their purity and incubated in the incubator at a temperature of 37 °C for 24 hours. The effect of the cold aqueous extract and the hot aqueous extract of common mistletoe was tested and the effect of these two extracts was studied against Staphylococcus aureus, Klebsiella pneumoniae and Acinetobacter baumannii, by well method, in this study we are using five different concentrations: 1gm, 0.8mg, 0.6mg, 0.4mg, 0.2mg. High inhibitory activity of the hot aqueous extract against Klebsiella pneumonia and Acinetobacter baumannii, as the results showed that 1 gm concentration was the most effective concentration against bacteria except for Staphylococcus aureus, intermediate activity against Klebsiella pneumonia and Acinetobacter baumannii, while a concentration of 0.6 mg had intermediate activity against Acinetobacter baumannii and did not show any activity against Klebsiella pneumonia and Staphylococcus aureus. While ( 0.2 mg and 0.4 mg) did not show any effectiveness in inhibiting the growth of bacterial isolates. As for the cold aqueous extract, it did not show any effect on any of the three isolates
