“…This finding is in good agreement with other reports [20][21][22] involving microbes other than B. hyodysenteriae. It is a limitation of our study that the active agents have not been identified and therefore the study is to be viewed as a pilot trial.…”

Filtrates of a water extract of commercially available garden thyme (Thymus vulgaris L.) were used for studying its possible bactericidal effect on Brachyspira hyodysenteriae, the causative agent of swine dysentery, by agar-diffusion technique. Five of the six studied Brachyspira strains have proven to be sensitive and one moderately sensitive in the in vitro tests. It was concluded that water extract of garden thyme possesses inhibitory effects against B. hyodysenteriae. In vivo experiments are needed to check the validity of this conclusion.

“…The difference in potency shown by the plant extracts may be due to different sensitivity of food associated strains, difference in concentrations, methods of extraction used in the study and the little diffusion properties of these extracts in the agar as suggested by El-Astal et al 15 . Although the plant extracts in the present study have shown higher antimicrobial activity, they still might be considered as potential drug agents for curing infectious diseases.…”

Caesalpinia pulcherrima (Linn.) Popularly known as Peacock flower in India belongs to family Caesalpiniace. The objective of the present work was to evaluate the in-vitro antimicrobial potency of the ethanolic and aqueous extract of Caesalpinia pulcherrima (Linn.) flower (CPF) using agar plate disk diffusion method against Escherichia coli, bacillus subtilis and streptococcus aureus. Cephalosporin (5µg/ml) use as a Standard drug. Results were subjected to minimum inhibitory concentration assay by two fold dilution method. Ethanolic extract of Caesalpinia pulcherrima was more effective against Escherichia coli, bacillus subtilis than aqueous extract and cephalosporin. While in case of streptococcus aureus aqueous extract is more effective than ethanolic extract and cephalosporin. Thus, the present study demonstrate that the traditional claim of Caesalpinia pulcherrima (Linn.) flower as an antimicrobial has been confirmed as the aqueous and ethanolic extracts displayed activity against the different microorganism used in study.

Objective: The leaf and root of Bombax buonopozense which have some ethnomedicinal applications were subjected to phytochemical screening and antimicrobial activity against some disease causing microorganisms. Material & Methods:The phytochemical composition was evaluated using standard procedures. Susceptibility of these clinical isolates (Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumonae, Proteus spp. and Escherichia coli) to the extracts was determined using the agar diffusion method.Results: Phytochemical screening revealed the presence of alkaloids, flavonoids, tannins, saponins, terpenoids, steroids, phlobatannins, anthraquinones and carbohydrates (mostly in root). The root extract demonstrated antibacterial activity against all the organisms tested, while the leaf extract had activity on S. aureus and B. subtilis only. Conclusion:The findings indicate that the root extract contain the most active components which may be used to source antibiotic substances for possible treatment of bacterial infections.
