Definitions
- the present invention relates to the field of antibacterials. It relates more specifically to a composition, especially antibacterial or pharmaceutical, especially used in the treatment of bacterial infections, especially induced by resistant bacteria, especially in hospital.
- nosocomial infections are serious infections that affect hospitalized patients. They are particularly dangerous for patients whose immune system is weakened, for example following treatments such as corticosteroids or chemotherapy, interventions such as transplants or diseases affecting the immune system such as Acquired Immunodeficiency Syndrome (AIDS). ).
- AIDS Acquired Immunodeficiency Syndrome
- nosocomial infections coincides with the emergence of bacteria resistant to existing antibacterials.
- Gram-positive bacteria exhibiting a phenomenon of drug resistance
- examples of gram-negative bacteria exhibiting a phenomenon of drug resistance mention may be made especially of Escherichia genus bacteria, in particular Escherichia coli, Pseudomonas-type bacteria, in particular Pseudomonas aeruginosa, and Acinetobacter-type bacteria, in particular particularly Acinetobacter baumanii.
- Staphylococcus aureus A worrying example is that of Staphylococcus aureus. Indeed, more than 95% of Staphylococcus aureus bacterial strains are resistant to penicillin and more than 60% have also become resistant to its derivative, methicillin. Strains with reduced susceptibility to vancomycin were further characterized. According to the World Health Organization, the rate of methicillin-resistant Staphylococcus aureus strains that became resistant to mipirocin, an antibacterial inhibitor of protein synthesis, increased from 2.7% to 65% within 3 years. This shows that the action of conventional antibacterial analogues can be rapidly countered by mechanisms of multiple resistance developed by the bacteria.
- Gram-negative bacilli including enterobacteria and Pseudomonas aeruginosa, are naturally resistant, mostly at a low level, to hydrophobic and / or high molecular weight antibacterials (penicillin G, penicillin M, macrolides, rifampicin, fusidic acid, novobiocin, vancomycin) because these antibacterials can not cross the outer membrane of the wall.
- One of the aims of the invention is thus to obtain active antibacterial agents against a broad spectrum of bacteria, in particular against resistant strains.
- these bacterial agents are active on strains having unnatural resistances.
- these bacterial agents are active on strains exhibiting natural resistance.
- a bacterium In infectious pathology, a bacterium is said to be "resistant" when the concentration of antibacterial it is able to withstand is significantly higher than that which can be obtained in vivo following a treatment.

- a 1: 1 mixture of two oils this means that there is 1% of each oil and in the case of a 2: 1 mixture the first oil is present at 1.3% and the second at 0.7%.
- Cinnamon Bark essential oil and Cinnamon essential oil has antibacterial activity on both Gram-positive and Gram-positive bacteria. This effect is also observed on resistant strains.

- bactericidal is obtained if one observes at least a fall of 3 logarithms of the starting inoculum.
- a bactericidal curve linking the number of bacteria to the time of contact with the oil can be plotted; it allows to see if the kinetics of bactericide is intense and fast or not.
- composition comprising a 1: 1 ratio of essential oil of cinnamon and cinnamon bark essential oil (as described in Example 6) shows bactericidal activity against strains 8132, 8154, 8152, 8155, ATCC 25922 (control), 9004 and 9001 specifically identified in the above examples.
