Effect of alcoholic extracts of Eucalyptus spp on the growth of some species bacteria isolated from mouth and nose infections in Samarra city

The study aimed to know the inhibitory effect of alcoholic plant extracts (ethanol, methanol) by the method of diffusion through the pit of Eucalyptus spp on the bacterial species Klebsiella pneumonia and Staphylococcus aureus isolated from patients with nasal infections and the species Escherichia coli and Streptococcus agalactiae from infected patients in the isolated city Samarra. Where the samples were collected within the period from 1/12/2020 to 4/1/2021, as it was found through the results that the plant extracts used in the study showed a different inhibitory action against the bacterial species under study. K.pneumonia bacteria showed an increase in the diameter of inhibition at a concentration of 100 mg ml/for the alcoholic extract (methanol) and a drop of 14.67 mm for the ethanolic extract 14.0 mm, while the methanol extract showed a significant difference at most of the concentrations used in the antibiotics used in the study,,
