Abstract
The study was conducted to analyze the antibacterial activity of
Plectranthus argentatus plant leaves. The plant sample was extracted
using methanol and water in the ratio 9:1. From the study the plant
Plectranthus argentatus was found to inhibit the growth of Escherichia
coli with a zone of inhibition of 11.67 ± 0.882, Serratia liquefaciens
zone of inhibition of 12.67 ± 0.667, Bacillus cereus 28.00 ± 1.154 and
Proteus vulgaris 11.00 ± 0.577. The bacteria which had a zone of
inhibition of less than 8 mm were termed to be unsusceptible. The data
collected and documented in this paper is a scientific justification that
the plant Plectranthus argentatus can be used to treat against various
diseases caused by E.coli, S. liquefaciens, Bacillus cereus and Proteus
vulgaris. However, more scientific data needs to be
provided to indicate the mode action of the plant active compounds against the pathogens.
