  abstract = {{L}udwigia peploides subsp. montevidensis and {L}udwigia grandiflora subsp. hexapetala, form aquatic dense stands, which cause major ecological and economical problems in many aquatic ecosystems in {F}rance. {H}owever, these species are known to release allelopathic compounds. {H}ere, antibacterial properties were assessed on samples from different plant organs, during {J}une, {J}uly and {A}ugust for {L}. peploides and throughout the development period, from {A}pril to {S}eptember, for {L}. grandiflora. {T}he disk diffusion method was used here to screen dimethylsulfoxide plant extracts against 5 {G}ram positive and 9 {G}ram negative bacterial strains. {T}he sensitivity of the bacteria tested to {L}. grandiflora extracts was greater than that to those of {L}. peploides. {M}aximum antibacterial activity was measured in {J}une, {J}uly or {A}ugust, depending on the plant organ, principally in leaf and flower extracts. {A}ctivity also varied according to the bacterial strains tested. {A} principal component analysis ({PCA}) showed that sensitivity to the plant extracts did not depend' on whether the bacterial strains are {G}ram positive or {G}ram negative. {T}hus, we found that a {G}ram positive strain, {S}taphylococcus aureus ({CIP} 76.25), and a {G}ram negative strain, {S}almonella enterica ({DSM} 10062), were similar in sensitivity. {A}ntibacterial activities of certain leaf or flower extracts of both species of {L}udwigia were revealed superior to those of several classic antibiotics tested. {T}he interest of this study concerns the therapeutical potential of the two {L}udwigia species.},
