Investigating Antimicrobial Effects of Tecomellaundulate ethanolic Extract on Antibiotic Resistant Acintobacterbomanii

Considering the increasing resistance of bacteria to antibiotics and the presence of antibacterial agents in plants, in this study, the antimicrobial activity of Tecomellaundulataethanolic extract on antibiotic resistance Acinetobacter bomaniihas been studied.

Materials and Methods: The leaves of Tecomellaundulata were collected from Saravan city and extracted by rotary machine. Acinetobacter bomanii strains were collected from urine specimens of Imam Khomeini and Ali ibn Abi Talib Hospitals. Minimum inhibitory concentration and minimum bactericidal concentration were determined by microdilution method. 

Results: The results of this study showed that the resistance of the strains was to amoxiclavanic (10%), ampicillin (20%), gentamicin (0%), ceftazidime (0%) and nitromicin (0%) antibiotics. The results of this study showed that the lowest inhibitory concentration of Tecomellaundulata is 0.62 mg / ml, which inhibits 6 strains in this concentration, while the highest inhibitory concentration is 5 mg / ml L, which inhibited 3 strains in this concentration. 

Discuss: By considering the results, obtained and increasing resistance of bacteria to chemical antibiotics, it is suggested that bacterial compositions of this plant can be used to treat bacteria.
