Neutralization of leukotoxicity in the presence of different plant extracts (1%) on cell lysis in cultures of THP-1 cell exposed for leukotoxin (200 ng/mL) in 2 h. N.e. No extract, (1) W. ugandensis twigs, (2) W. ugandensis leaves, (3) T. asiatica twigs, (4) T. asiatica leaves, (5) Eucalyptus spp. twigs, (6) G. similis (oirii) twigs, (7) Guava (P. guajava) leaves, (8) fresh extract of W. ugandensis leaves, and (9) fresh extract of W. ugandensis bark. White bar without leukotoxin, black bar with leukotoxin and gray bars leukotoxin + plant extract. Mean ± SD of four experiments analyzed in triplicates. Student’s t-test was used to examine significant difference of leukotoxicity without plant extract (p < 0.05 *. p < 0.001 ***).
