In Vitro Antibacterial Activity of Solanum Lycopersicum Extract against some Pathogenic Bacteria

The aqueous extract of tomato evaluated for activity against medically important bacteria Escherichia coli, Klebsiella sp., Pseudomonas sp Acinetobacter, this research was screened the capability of the extract to inhibit the growth of some isolated bacteria. The in vitro antimicrobial activity was performed by agar well diffusion method. The aqueous tomato extract showed the maximum antimicrobial activity when diluted with honey than diluted with distal water. Sensitivity and resistance to extract and antibiotic varied from bacteria to another but Solanum lycopersicum proved active effects against all bacteria at pure extract without resistance with inhibition zone ranged(35-50) mm when we mixed Solanum lycopersicum with honey. The extract exhibited the higher activity until in diluted concentrations,comparative by using the extract alone. The use of tomato extract with known antimicrobial properties, can be of great significance in therapeutic treatments in vivo
