Phytotherapy is increasingly used againstrninfections in many parts of the world. Plants of the genus Artemisia, Asteraceae,rnare among those most exploited and several of its species were thus describedrnas having antibacterial and antifungal effects. The infusions of Artemesiarnannua has been indicated as having disinfecting capacity in bacteriologicalrncontaminated water. The cultivability of Enterococcus faecalis and Escherichiarncoli was carried out in different extract solutions of A. annua aimedrnat describing the order of importance of some abiotic factors on this process.rnThe bacterial abundance undergoes temporal variation with respect to pH ofrnextract, A. annua extract and glucose concentrations, light intensity. The hierarchical organization of these factors has been carried out byrnexpressing percentage and ranking in descending order of the sum of squares ofrneach MANOVA test factor. It showed that cultivability of E. faecalis in A.rnannua extract solutions was influenced by the incubation durations, followedrnby the type of dilutions, light intensity, pH of extract, concentration of A.rnannua extract, and glucose concentrations. On the contrary, therncultivability of E. coli in A. annua extract solutions wasrninfluenced by the incubation durations, pH of infusion, type of dilutions,rnconcentrations of A. annua extract, glucose concentrations and lightrnintensity. The increase of the incubation durations, light intensity and pH ofrnextract solutions caused a significant (P≤0.01) decrease of the effect of A.rnannua on E. faecalis and E. coli cultivability.
