Bacteria of the genus Thermoactinomyces have the ability to produce antibacterial bioactive compounds. This bioactive compound can be used for combating diarrheal agents such as Escherichia coli and Staphylococcus aureus. This study aims to determine the antibacterial activity of the metabolite extract from Thermoactinomyces sp. (H24) against Escherichia coli and Staphylococcus aureus. Methanol was used as a solvent for the extraction of bacterial bioactive compounds. Antibacterial activity was analyzed by the diffusion method with several extract concentrations (0.75 mL, 1.5 mL, 2.25 mL, and 3 mL), 10% DMSO as the negative control, and ciprofloxacin as the positive control. Our result shows that Termoactinomyces sp. (H24) extract has an inhibitory effect on the growth of  E. coli and S. aureus with an effective concentration of 2.25 mL (inhibition strength: very strong).

Human pathogenic microorganisms have developed resistance in response to indiscriminative use of commercial drugs. Plants produce many secondary metabolites with microbiocidal activity hence their use in traditional medicine. Herbalists in Kenya use medicinal plants including Solanum incanum in treating microbial infections. Though S. incanum has been used to treat different diseases in humans and animals, there is little information on antimicrobial activities of its extracts against Escherichia coli and Staphylococcus aureus. In this study, phytochemical analysis and antibacterial activity of solanum incanum leaves, roots and seeds extracts were determined. Ethanolic and aqueous extracts of leaf, root and seed of concentrations 25, 50, 75 and 100, and amoxicillin 25 mg/ml (control) with three replications were used for antibacterial analysis by the agar-well diffusion method. The results were subjected to analysis of variance at P < 0.05. Phytochemical screening revealed the presence of alkaloids, flavonoids, glycosides, saponins, steroids and tannins. Solanum incanum exhibited significant antibacterial effect against the two test bacteria. Ethanol extracts were more active than extracts against the bacteria. Ethanol extracts at 100% inhibited growth of Staphylococcus aureus more than the Escherichia coli. The zones of inhibition for Staphylococcus aureus were 35.0±0.6 mm, 30.94±0.3 mm and 30.14±0.64mm for seed, root and leaves respectively.On the other hand, the zones of inhibition for Escherichia coliat 100% ethanol were 27.20±0.06, 23.14±0.12 and 21.0±0.4 seed, root and leaves respectively.The results validate the use of these plants in ethnomedicine and potential of this plant in treating infections caused by the two bacteria.

The study was carried out to determine the antibacterial activities and toxicological evaluation of Anogeissusleiocarpus and Psidiumguajava on Escherichia coli and Staphylococcus aureus isolated from clinical samples. The plants leaves were extracted using Hexane, Methanol, Ethanol and Water. Various concentrations (50, 25, 12.5 and 6.25mg/ml) of the crude extract of the plants were prepared and their antibacterial activity against Staphylococcus aureus and E. coli was determined using Agar well (Diffusion) method. Toxicity of the plants was evaluated, acute toxicity test, kidney and liver function tests. The result revealed that at 50mg/ml concentration, the leaf extract of Psidiumguajava was active against Staphylococcus aureus and E. coli exhibiting the highest zones of inhibition of 19mm and 9mm respectively. Whereas The leaf extract of Anogeissusleiocarpus only inhibited the growth of Staphylococcus aureus recording highest zone of inhibition of 15mm at a concentration of 50mg/ml. The plant extracts were found to be non-toxic as the LD50  was above 5000mg/kg and the biochemical parameters evaluated for both liver and kidney function tests revealed values that are within normal range. Hence the study established that consumption of the leaves of P.guajava for medicinal purpose can be said to be innocuous, as such the plant could be regarded as a potential candidate in the search of potent and harmless plants of therapeutic value.

This research aims to identify the compound group and determine the antibacterial activity of n-hexane, chloroform, and methanol fractions of Artocarpus integer (Thunb.) Merr stem bark. All fractions contain groups of terpenoid and steroid compounds. Antibacterial activity was detemined using agar diffusion method with MHA (Muller Hinton Agar) media on Escherichia coli (gram negative) and Staphylococcus aureus (gram positive). Ciprofloxacin was used as a positive control and methanol as a negative control. The three fractions were able to inhibit the growth of Escherichia coli and Staphylococcus aureus. The chloroform fraction showed the highest activity after 48 hours incubation with inhibition zones of 10.8 and 10.4 mm respectively.
