Antibacterial Effect Of Annona Muricata (Sour Sop) Leaf, Bark And Fruit On Some Selected Organisms
ABSTRACT
The
antibacterial effect of Annona nuricata
Linn (sour sop) leaf, bark, and fruit on some selected organisms was investigated
using Escherichia coli, Salmonella and Shilgella. Different concentrations
(100mg/mi, 50mg/mi and 25mg/ml) of the aqueous and ethanol extracts of the leaf
and bark, and the juice extract of the fruit were used. The Kirby-Bauer disc
diffusion method was used for the susceptibility test. The results showed that
the ethanol bark extract and the aqueous leaf extract at different
concentrations showed little inhibition against the organisms. For ethanol bark
extract the zone of inhibition observed against the test organisms were 4mm
against Salmonella sp and 3mm against Shigella sp at 100mg/ml concentrations.
For the aqueous extract of the leaf, the zones of inhibition were 4mm for E.
coli and 3mm for Shigella sp at 100mg/ml concentration. The fruit juice extract
also did not show any inhibition against all the three organisms tested. The
antibiotics used as control (gentamicin and chloramphenicol) showed some degree
of inhibition against all the organisms. The result of this study shows that
this plant cannot be effectively used to treat infections caused by this test
organisms, hence it cannot be recommended for use in their treatment.
