Statement of the Problem:
Bacillary dysentery which is caused
by one or more types of
Shigella
species, highly prevalent in hot
countries with poor sanitation like Sudan especially in children
is a potentially serious disorder if left untreated. It can lead
to dehydration in children or liver abscess if it is spread from
intestine to the liver stream. Options of treating Shigellosis
with antimicrobials are becoming limited because of globally
emerging antimicrobial resistance and the long use of these
synthetic drugs causing many side effects. Therefore, the
search for effective and safer antimicrobial agents from plants
has become an area of interest in active research. The purpose
of this study is to investigate the antimicrobial activity of the
ethanol extracts of
Peganum harmala
and
Trachyspermum ammi
against isolated
Shigella flexneri and Shigella dysenteriae
causing
bacillary dysentery.
Methodology:
T. ammi
and
P. harmala
were extracted by 96%
ethanol using Soxhlet apparatus. The antimicrobial activity of the
extracts was investigated according to the disc diffusion method
and the minimum inhibitory concentrations of the extracts were
determined.
Findings:
All tested bacteria (
Shigella flexneri and Shigella
dysenteriae
) were found to be sensitive against
T. ammi
seed
extracts, while the same bacteria were resistant for amoxicillin
and amoxicillin + clavulanic acid and insensitive for P. harmala.
The tested bacteria were also sensitive to gentamycin 5 mg/ml,
but it has a lower inhibition zone than that of T. ammi 100 mg/ml.
C
onclusion & Significance:
T. ammi
ethanolic extract possessed
antimicrobial activity as stated in literature.
Recommendations:
Further investigations should be carried out
to find the bioactive compounds for developing new antibiotic.
