The aim of this research is study the effect of some citrus juices such as lemon Citrus limon , bitter orange Citrus Aurantium and orange Citrus sinensis in bacteria Klebsiellae pneumonia in vitro, four concentrations usage (25%, 50%, 75%, 100%) compared to some industrial antibiotics (Bacitracin, Erythromycin, Novobiocin ), as the results show the juices have important impact in inhibiting the growth of bacteria and the lemon greatest influence in the growth with concentration 100%, where the inhibition rate after 24 hours was 30 mm and decreasing with low concentration reaching 15 mm at 25%, while the bitter orange had the second-level after lemon , where the inhibition rate was 23 mm with concentration of 100% and 5 mm with 25%concentration . and at increasing the incubation period to 48 hours , lemon inhibition with concentrations (75% and 100%) was 19 mm and decrease to 16 mm with a concentration of 100% after 72 hours , while the bitter orange has not had any significant inhibition when increasing incubation period , while the orange did not have any mention Influence of all concentrations and for three incubation period ,and the same results obtained with industrial antibiotics .
