Comparative study on the effects of Aloe vera extract in clinical strains of Staphylococcus aureus, Klebsiella, Staphylococcus epidermidis and Escherichia coli compared to antibiotics of choice

Nowadays, with the development of drug resistance, the use of herbs as an alternative to chemical drugs is considered by researchers. In this work, effects of Aloe vera extracts on clinical isolates was studied. Aloe vera plant medicinal plants were obtained from a greenhouse. Three extracts including essential oils, extracts and no essential oils and essential oil extraction method also includes a complete extract of Aloe vera were prepared Percolation total. To investigate Microbiology extracts of two strains of Staphylococcus aureus and Staphylococcus epidermidis clinical strain of Gram-positive and Gram-negative isolates of Klebsiella pneumoniae and Escherichia coli strains Staphylococcus aureus ATCC25923 were used as well. Evaluate the effect of two Kirby-Bauer disk with the minimum inhibitory concentration (MIC) was performed using microplate dilution. Turbidity was determined by an ELISA reader apparatus. All extracts of aloe vera on Klebsiella with a diameter of 32 ± 2 mm mg/ml285.7 concentration with microplate dilution method was 2.23 mg/ml. Staphylococcus aureus and MIC zone diameter of 30 ± 2 mm and mg / ml 2.23, Staphylococcus epidermidis and Escherichia coli mg/ml4.46 mm 17.85 mm 30 ± 5 mg / ml 17.85 respectively. Similar concentration of 17.85 mg ml Aloe Vera with a circle formed by the disk mc / ml 10 gentamicin was shown. This effect is similar to other bacteria antibiotics gentamicin, clindamycin, erythromycin, and Cefixime compared with Aloe Vera extract has been proven. Essential oils made from all parts of the same whole extract of aloe vera, but not essential extracts, bacteria studied were ineffective. In this study the effects of similarity and some excess water Asrsarh Aloe Vera with common antibiotics on bacteria causing the infection was confirmed. Therefore, by production of appropriate pharmaceutical plant drugs with fewer side effects, bacterial infections couled be treated properly.
