The study was conducted from January to March 2012. In this study colorimetric VITEK-2 Compact system used for its accuracy and rapidity to identify isolates and to detect several antimicrobial resistances.The study also investigate the antibacterial effect of Kombucha tea on isolated bacteria from diabetic foot ulcer. The bacteria isolated were eight gram negative bacteria, namely, Acinetobacter baumannii 3 (2%), Enterobacter cloacae 5 (4%), Escherichia coli 13 (10%), Klebsiella pneumoniae 7 (6%), Citrobacter spp. 4 (3%), Proteus mirabilis 3 (2%), Proteus vulgaris 3 (2%) and Pseudomonas aeruginosa 44 (35%). Four gram positive bacterium, Enterococcus faecalis 6 (5%), Staphylococcus aureus 17 (13%), Staphylococcus epidermidis 13 (10%) and Streptococcus spp. 9 (8%). The antimicrobial activities of antibiotics showed that, all isolates are sensitive to Ciprofloxacin, Levofloxacin and Ofloxacin. The resistance to other types of antimicrobial differ with different isolate. The effect of Kombucha tea on all isolates wasclear at 7days of incubation; the diameter of inhibition was 6mm for Acinetobacter baumannii, Proteus vulgaris and Enterococcus faecalis. 7mm for Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Citrobacter spp., Staphylococcus epidermidis and Streptococcus spp. 8mm for Proteus mirabilis, Pseudomonas aeruginosa and Staphylococcus aureus. The maximum activity of fermented tea was recorded at 14days incubation of Kombucha organism against all isolates, the diameter of inhibition was 21mm for Acinetobacter baumannii, 24mm for Enterobacter cloacae, 23mm for Escherichia coli, Staphylococcus epidermidis and Streptococcus spp., 16mm for Klebsiella pneumoniae, 22mm for Citrobacter spp. and Enterococcus faecalis, 25mm for Proteus mirabilis and Staphylococcus aureus, 20mm for Proteus vulgaris, 26mm for Pseudomonas aeruginosa. The antibacterial activity of Kombucha tea decrease with increase incubation periods28 days.
