One of the most prevalent forms of infection worldwide is urinary tract infection, and it can be determined as: cystitis, lower urinary tract infection, bladder infection or as pyelonephritis which is the most severe form of this condition where The infection settles in the ureters and kidneys. In most cases the infection is caused by the bacterium Escherichia coli. Several alternative methods based on plants or plant extracts are tested for treatments that replace synthetic antibiotics. This study aimed to analyze the in vitro antibacterial activity of garlic essential oil (allium sativum l.) And garlic extract against Escherichia coli bacteria. The essential oil and garlic extracts were diluted to 100%, 50% and 25% concentrations and applied to medium containing E. coli strains together with conventional antibiotics ciprofloxacin and levofloxacin for comparison of halo on antibiogram. After incubation for 24 hours at 36 ° C, the results showed that the essential oil did not show satisfactory results, while garlic extract obtained halos (mm) at all concentrations analyzed (100% 13.33 ± 2.59 50% 9.22 ± 1.48 and 25% 6.22 ± 4.27 and the 100% concentration obtained remarkable circumferences very close to those created by the conventional antibiotics ciprofloxacin (11.56 ± 4.27) and levofloxacin (13, 44 ± 3.43).
