Primum non nocere is a principle proclaimed by Hippocrates and remains relevant throughout the history of medicine. Unfortunately, pharmacotherapy does not always correspond to it. Although modern oral antibacterial drugs generally have a favorable safety profile, there are still many side effects. Antibacterial, like all medicines, have side effects, some of the side effects can be serious and some are dire. The use of antibacterial drugs in all areas of medicine, often unreasonable indications for their use, free access for the potential consumer - all this leads to irrational use of drugs, starting from an early age. More than 50% of diseases are infectious in nature. Infectious drugs account for 20% of all drugs currently used in medicine. The misuse of antibiotics is fraught with the development of antimicrobial resistance in the pathogen.

In Malaysia, Entada spiralis Ridl. from Leguminoceae family grows wildly and the scientific study of it has not been explored deeply. Entada spiralis Ridl. is a liana or woody climber plant which is locally known as "akarbeluru" or "Sintok". This study is performed to evaluate the antibacterial activity of Sintok extract from the stem bark of Entada spiralis against skin bacteria infections by the disc diffusion method. Two types of skin bacteria known as Staphylococcus aureus and Streptococcus pyogenes were selected and tested against the water extracted Sintok. Sintok concentration of 1600mg/ml gave the highest inhibition zone diameter against Streptococcus pyogene rather than Staphylococcus aureus with a diameter of 25.5 mm and 18. mm, respectively. This study indicates clear evidence supporting the traditional use of Entada spiralis in treating skin infections related to bacteria

Out of a hundred horses, fecal samples Escherichia coli was isolated from 37 samples of
different ages, The isolated samples had been used to examine the effect of peganum
harmaline on isolated E.coli in vitro and in vivo.
The goal of this research was to determine the antimicrobial activity of peganum
harmaline extract by means of (ethanol: methanol 1:1) in opposition to Escherichia coli at
various 40,20, 10, 5, 2,5, 1,25 and 0,625 mg/ml concentrations in each plastic and glass
tube. The values of MIC (minimum inhibitory concentration) and MBC (minimum
bactericidal concentration) for the extract against E.coli were equal to (0.625 mg/ml) for
MIC and (10 mg/ml) for MBC on bacteria which cultured on glass tube while the MIC
value was 40 mg/ml and MBC was10 mg/ml on plastic tube. The effect of Peganum
harmaline on the formation of E.coli biofilm was investigated and the biofilm inhibitory
concentrations were 40-6.25mg / ml in vitro. In vivo, a group of laboratory mice used, the
LD50 of peganum harmaline extract was tested orally by up and down method and found
to be 1030 mg/kg body weight, the extract used as 103 mg/kg bodyweight treatment after
causing E.coli infection at 1×108 CFU/ml in laboratory mice the treated persist for two
weeks in group one and three weeks in the second group as well as three week treated in
the third group from the second days after infection while the control group left without
treated and the mice sacrificed after second, third and fifth days of infection. The result
shows histopathological changes in all treated groups, especially in the third group and
that refers to the antibacterial effect of the peganum harmaline ethanolic extract when
compared to the infected control group.
