Abstract: BLANCAFLOR, ERIC REYES. IN VITRO STUDY OF THE ANTIBACTERIAL PROPERTY OF CRUDE TAGALOG ONION (Allium cepa L. var. ascalonicum) BULB EXTRACT ON SELECTED BACTERIA. Undergraduate Thesis. Doctor of Veterinary Medicine, Cavite State University, Indang Cavite. April 2004. Adviser: Nelson J. Montialto, DVM. A study was conducted to determine the antibacterial property of crude Tagalog onion (Allium cepa L. var. ascalonicum) bulb extract against Pseudomonas aeruginosa, Streptococcus' pyogenes, Klebsiella pneumoniae, and Bacillus subtilis in vitro and to determine the effective concentration of the extract against these selected bacteria. The zones of inhibition produced around the improvised crude Tagalog onion bulb extract disc and the control were measured at the 24th and 48th hour of incubation. Results indicated inhibitory effects of crude Tagalog onion bulb extract against S. pyogenes and B. subtilis even at the lowest treatment concentrations while inhibition against K pneumoniae was at higher concentrations. P. aeruginosa was relatively resistant, not producing any zones of inhibition even at the highest concentration. Results of the study revealed significant differences among treatment means at 24 and 48 hours of incubation for S. pyogenes, K pneumoniae, and B. subtilis only.
