ANTIMICROBIAL ACTIVITIES OF NATURAL HONEY FROM MEDICINAL PLANTS ON ANTIBIOTIC RESISTANT STRAINS OF BACTERIAM. RAJASEKARA PANDIAN, G. SHARMILA BANU1 AND G. KUMAR
Samples of natural honey from different medicinal plants were studied for their antimicrobial activities on antibiotic resistant strains of bacteria isolated from human pathology. Samples of honey from four different plants mainly Thespesia populnea, Calotropis gigan tea, Leucas aspera, Azadirachta indica and multifloral were collected from different regions in Tamilnadu. Dilutions of honey ranging from ½, 14, 1/ 8 and 1/16 were tested by the agar well diffusion method on various strains of bacteria including E. coli, Staphylococcus aureus, Bacillus and Pseudomonas. Results revealed that most of strains were inhibited by the dilution 1/2 and 1/4 The Gram negative bacteria were more sensitive to honey than Gram positive bacteria. No difference among the different origins of honey (plants) was observed. All the samples showed strong antimicrobial activities on the bacterial strains, which were first tested for their resistance to antibiotics.
