Abstract and figures
The
efficacy of Boswellia dalzielii (Frankincense) stem bark extract on
some bacterial and fungal organisms was evaluated for its in-vitro
antimicrobial activities against Staphylococcus aureus, Streptococcus
pyogenes, Escherichia coli, Salmonella gallinarium, Aspergillus
fumigatus and Candida albicans. The research work was carried out in
Biochemistry and Microbiology Laboratories of Federal College of Animal
Health and Production Technology, National Veterinary Research
Institute, Vom. Well diffusion method was carried out on nutrient agar.
MIC, MBC and MFC of the test organisms were carried out on nutrient
broth. The phytochemistry revealed the presence of saponin, tannin,
flavonoids, cardiac glycosides, steroids, terpens and phenol in ethanol
extracts while resin, alkaloid and glycosides were absent in hot water
extracts. Alkaloid was also absent in ethanolic extract. The aqueous
extract of the plant exhibited neither antibacterial nor antifungal
effects against all test organisms used in the study while the ethanolic
extract of the plant showed both antibacterial and antifungal effects
on the study organisms. The results of this study also showed that the
ethanolic extract of Boswellia dalzielii stem bark has activity against
all bacteria species used in the study (broad spectrum activity). For
gram-negative and positive bacteria, Salmonella gallinarium and
Staphylococcus aureus were the most sensitive while Escherichia coli and
Streptococcus pyogenes were the least respectively. Candida albicans
was more sensitive than Aspergillus fumigatus. It was concluded that the
test organisms were susceptible to ethanol extracts of the plant and
may be good source of antibiotics.
