Efficiency of ethanol extract of Moringa oleifera lam leaves for the treatment of Staphylococcus aureus infections in chicks

The efficiency of ethanol's extract of Moringa oleifera was evaluated in Staphylococcus aureus infection on Harco chicks. For this, 150 Harco chicks divided in 5 lots were used: A negative control (not inoculated and not treated); 0.5 g/L; 1.5 g/L of M. oleifera; 0.5 g/L of Flumequine (R) 50 and a positive control (inoculated but not treated). The test of chi(2) was used for the comparison and the test of student for the means comparison between lots. In vitro 1.5 g/L of the extract shows a positive result on S. aureus. However only 0.5 g/L of the extract has proved an efficiency in vivo. Compared to the other treatments, only 0.5 g/L of M. oleifera has allowed a daily gain of weight during the 4(th) period (11.4 +/- 1.68). There was a significance difference at 1% for food consumption. The treatment of 0.5 g/L of M. oleifera has decreased the leukocytes number from 5363333.33 to 4383333.33/ml of blood.
