IN-VITROANTIBACTERIAL EFFICACY OF ALOE VERA (ALOE BARBADENSIS MILLER, 1768) LEAF AND GEL IN DIFFERENT EXTRACTS AGAINST SOME SELECTED PATHOGENIC BACTERIA

Aloe veraleaf and gel is widely used as a traditional folk medicine for the treatment of different infectious diseases. The present study is to investigate the antibacterial efficacy of A. veraleaf and gel in different extracts like aqueous, chloroform and ethanol. They were tested against four Gram positive bacteriaStapylococcusaureus,Staphylococcus epidermidis, Bacillus cereus and Bacillus subtilis and four Gram negative bacteriaEscherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa and Salmonella typhi.The susceptibility of the bacterial organisms to the three different extracts of A. veraleaf and gel revealed the ethanol extract of A. veragel to possesses maximum growth inhibition onGram positive bacterium (B. subtilis), than on the Gram negative bacteria.Hence, the present studysuggeststheethanol extract of A.veragel to be used as an alternate antibacterial agent.
