摘要

Background: Tuberculosis remains a major public health threat. Studies have shown that medium chain fatty acids (MCFA), such as, those found in Virgin Coconut Oil (VCO), possess activity against a wide range of microorganisms including?Mycobacterium tuberculosis. The goal of the study was to determine the in-vitro susceptibility of?M. tuberculosis (TB) isolates to two commercial brands of VCOs each containing different amounts of lauric acid and produced?by two different extraction processes. Two brands of VCO were tested for their anti-TB actions compared to pure lauric acid and a negative control. Two replicate runs were done. VCO samples were inoculated with 0.1 mL of the H37RV strain of M. tuberculosis and incubated at 370C with shaking for 5 days. After incubation, the mixtures were diluted 10-fold up to 10-4?concentration to obtain countable colonies using Middlebrook 7H10 agar plates and Lowenstein-Jensen (L-J) slants. Colony growths of M. tuberculosis were examined in each dilution every week for three to eight weeks.
