EFFECT OF SOME EXTRACTS OF Funaria sp. ON SOME TYPES OF BACTERIAFunaria sp

the aim of this study is to investigate the effect of cold and hot water extracts of green parts of Funaria sp. on colonies growth of Escherichia coli and Klebsiella sp. pathogenic strain and find the half lethal concentration (LC50). Also, it has been done in period from 1/8/2017 to 1/2/2018 under microbiological laboratory conditions. The results showed that cold water extract was more effective on bacteria than hot water extracts, which the LC50 in cold and hot water (2) mg/l and (˂ 0.5) mg/l, and (˃ 2.5) mg/l and (1.7) mg/l for E. coli and Klebsiella sp. respectively. Klebsiella sp. was more effective by extracts than E. coli bacteria in different concentrations. Results also showed there was a significant differentiation in level of probability 0.05 and negative correlation coefficient between results. Funaria sp.
