Antibacterial Activity Of Leaf Extracts Of Colocasia Esculenta And Caladium Bicolor On Clinical Isolates
ABSTRACT
Two extracts from two Nigeria medicinal
plants, Colocasia esculenta and Caladium bicolor were screened for
antibacterial activities using disc diffusion and micro dilution broth assays.
Methanol extracts of each of the plants were tested against four microorganisms
consisting of two Gram positive bacteria (Staphylococcus aureus and
Streptococcus faecalis) and two Gram negative bacteria (Escherichia coli and
Pseudomonas aeruginosa). The antibacterial activity was measured by the
diameter zone of inhibition and minimum inhibitory concentration (MIC). The
extracts exhibited moderate broad spectrum antibacterial activities against the
microorganisms. The diameter of zone of inhibition ranges from I 0mm-15mm at
2000mg/ml of crude extract per disc. The MIC values were between 125mg/ml-1
00mg/ml. The activities of some of the crude extracts were comparable to the
reference antibiotics (Gentamicin) at standard concentration per disc. These
findings have shown the potentials of these extracts for antibacterial
activities against clinical isolates.
