“…22,23 Consistent with the results of the currently study, water and ethanol extracts of Bridelia ferruginea (Euphorbiaceae) showed antimicrobial activities against many pathogenic bacteria in vitro. 24 The ethanolic extract of A. indica had the greatest antimicrobial activity against all investigated pathogens. Other researchers have also assessed the antibacterial efficacy of ethanolic extract of A. indica.…”

Background and purpose: This study was carried out to learn more about the potential prophylactic or antibacterial activity of the plant Acalypha indica against selective pathogenic bacteria. Experimental: The test organisms were Sarcina lutea IFO 3232, Bacillus subtilis IFO 3026, Pseudomonas denitrificans, Escherichia coli IFO 3007, Klebsiella pneumoniae ATTC 10031, Xanthomonas campestris IAM 1671, and Proteus vulgaris.Leaf, stem, and bud powder of Acalypha indica were dissolved in various solvents, and the extracts were tested for antimicrobial activity through the disc diffusion method. GC-MS profiling was performed to characterize active chemical compounds in the essential oil of Acalypha indica. Results: The ethanol extract showed the highest activity against all bacteria, while the petroleum ether extract yielded the highest zone of inhibition against Proteus vulgaris (11.83 ± 1.75 mm). The minimum inhibitory concentration (MIC) of the ethyl acetate extract against Bacillus subtilis was 16 µg/mL. Phytochemical screening by GC-MS revealed a total of 12 bioactive compounds. Conclusion:Extracts of Acalypha indica may be useful in formulating and synthesizing new antibacterial drugs.

“…The antimicrobial screening of the plant extracts were determined using agar well diffusion method as given by Irobi et al (1994). The organisms collected were sub-cultured into prepared normal saline and incubated at 37°C for 30 min, the concentration of each organism was increased to form a turbidity that matched with 0.5 McFarland's standard by visual comparison at which it is assumed that the number of cells is 1.5 × 10 8 cfu/ml.…”

The phytochemical screening and comparative study of antimicrobial activity of Aloe vera extracts was carried out. The phytochemical screening revealed the following metabolites: saponins, alkaloids, glycosides, tannins, protein, and flavonoids. While cardiac glyocosides and steroids were absent. The antimicrobial activities of the gel in 10% DMSO, methanol and aqueous extracts of green rind and leaf pulp were carried against some pathogenic clinical isolates, namely, Bacillus subtilis, Staphylococcus aureus, Proteus mirabilis and Candida albicans. The DMSO extract of the gel and the methanol extract of the green rind showed greater potency against tested microorganisms in the order B. Subtilis> S. aureus> C. albicans and S. aureus>C. albicans>B. subtilis>P. mirabilis respectively with different zones of inhibition ranging from 18 to 35 mm gel, 15 to 18 mm for leaf pulp methanol, 20 to 32 mm green rind methanol, also 12 to 14 mm and 14 to 23 mm for leaf pulp aqueous and green rind aqueous respectively. The minimum inhibitory concentration (MIC) of the extracts against organisms ranged from 6.25 to 25 mg/ml while the minimum bactericidal concentration (MBC) was within the range of 12.5 to 50 mg/ml. The study revealed that the green rind methanol extract and gel have greater medicinal potential against B. subtilis.

Aim:The study assessed and compared the antibacterial activities of different honey types in Southwest Nigeria. It also compared antibacterial potency of the honey with a standard antibiotic. This was with a view to ascertain and providing information on cheaper alternative potent antibacterial product of natural source as well to confirm the antibacterial efficacy of the honey in Southwest, Nigeria. Materials and Methods: The sensitivity testing of honey samples was determined using agar-well diffusion method. The minimum inhibitory concentration of honey samples was determined using broth tube dilution method. Minimum bactericidal concentration of honey samples was determined. The data obtained were analyzed with appropriate statistical methods. Results: The zone of inhibitions exhibited by all honey samples against the test bacteria ranged between 6 ± 0.0 and 30.7 ± 1.2 mm. The death rate ranges between 52.1% and 94.6% in the dark amber honey sample (H9) after 120 min of contact time at the same concentration. Conclusion: In this study, super dark amber honey shows the highest antimicrobial property which compared favorably with the standard antibiotic (streptomycin). This honey has shown to have a potent broad spectrum antibacterial activity. However, further studies are recommended to assess its practicality in terms of use in the clinical setting.
