However, synergistic combinations of plant extracts with conventional antibiotics are a far more effective approach in overcoming resistance and potentiating the activity of antibiotics that are otherwise ineffective against resistant bacterial strains. &lt;strong&gt;Methods&lt;/strong&gt;: In this study, &lt;em&gt;Petalostigma&lt;/em&gt; spp. (native Australian medicinal plants) extracts were combined with a range of conventional antibiotics and tested against various microbial triggers of autoimmune diseases. The fruit and leaves were extracted separately with solvents of varying polarity and investigated for the ability to inhibit bacterial growth using disc diffusion and liquid dilution MIC techniques. &lt;strong&gt;Results&lt;/strong&gt;: The methanolic and water extracts showed low to moderate inhibitory activity against several microbes. However, combinations of the mid-low polarity extracts with conventional antibiotics proved significantly more effective in inhibiting the growth of &lt;em&gt;Proteus mirabilis and Acinetobacter baylyi&lt;/em&gt; (bacterial triggers of rheumatoid arthritis and multiple sclerosis respectively). In total, 14 different combinations proved to be synergistic. Notably, two antibiotics (chloramphenicol and erythromycin) with no inhibitory activity against &lt;em&gt;P. mirabilis&lt;/em&gt; alone were shown to have substantial activity when tested in combination with &lt;em&gt;Petalostigma&lt;/em&gt; spp. extracts. &lt;strong&gt;Conclusion&lt;/strong&gt;: Although the mechanisms of synergy are still unclear, studies indicate that compounds within&lt;em&gt; Petalostigma&lt;/em&gt; spp. may mimic the actions of resistance modifying agents, thus potentiating the activity of several antibiotics that are relatively ineffective alone. Isolation of these agents may be highly beneficial in drug design against several bacteria including the microbial triggers of rheumatoid arthritis and multiple sclerosis.&lt;/p&gt;

It is especially well known as a component of the Ayuverdic medicine Triphala. This study focuses on the growth inhibitory activity of &lt;em&gt;E. officinalis&lt;/em&gt; fruit extracts against some bacterial triggers of autoimmune inflammatory diseases, both alone and in combination with conventional antibiotics. &lt;strong&gt;Methods:&lt;/strong&gt; &lt;em&gt;E. officinalis&lt;/em&gt; fruit powder was extracted with solvents of varying polarity and screened for bacterial growth inhibition by disc diffusion assay. The minimum inhibitory concentration (MIC) was quantified by both liquid dilution and disc diffusion techniques. To screen for combinatorial effects, the &lt;em&gt;E. officinalis&lt;/em&gt; fruit extracts were combined with a range of conventional antibiotics and tested against each bacteria using a liquid dilution assay. Toxicity was examined using &lt;em&gt;Artemia&lt;/em&gt; nauplii and HDF bioassays. &lt;strong&gt;Results:&lt;/strong&gt; The ethyl acetate &lt;em&gt;E. officinalis&lt;/em&gt; fruit extract displayed the strongest growth inhibitory activity against all of the bacterial triggers of autoimmune inflammatory disease. This extract was a particularly potent inhibitor of P. aeruginosa growth, with an MIC values as low as 264 &amp;mu;g/mL. The ethyl acetate extract was also a moderate to strong growth inhibitor of &lt;em&gt;P. mirabilis&lt;/em&gt;, &lt;em&gt;K. pneumonia&lt;/em&gt; and &lt;em&gt;A. baylyi&lt;/em&gt;, with MIC values generally 1000-1500 &amp;mu;g/mL. The methanolic and aqueous extracts also inhibited the growth of all bacteria, although generally with only moderate to low activity. Whilst no synergistic interactions were detected in combinations containing the &lt;em&gt;E. officinalis&lt;/em&gt; fruit extracts and conventional antibiotics, a number of combinations produced additive effects. These combinations are beneficial as they provide enhanced antibacterial efficacy compared to treatment with the antibiotic or extract components alone. No antagonistic interactions were detected. Therefore, use of the extracts in combination with conventional antibiotics would not compromise the antibiotics efficacy. All extracts were nontoxic in the &lt;em&gt;Artemia&lt;/em&gt; nauplii and HDF toxicity assays, further indicating their potential for medicinal use. &lt;strong&gt;Conclusion:&lt;/strong&gt; The &lt;em&gt;E. officinalis&lt;/em&gt; fruit extracts were moderate inhibitors of the bacterial triggers of selected autoimmune inflammatory diseases. Furthermore, the extracts potentiated the activity of chloramphenicol and tetracycline against otherwise resistant bacterial strains. Isolation of the active compounds and the potentiating agents may be beneficial in antibiotic drug design.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">654</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Adrian Hutchings&lt;sup&gt;1&lt;/sup&gt;, Ian Edwin Cock &lt;/strong&gt;&lt;sup&gt;&lt;strong&gt;1,2*&lt;/strong&gt; &lt;/sup&gt;&lt;/p&gt;

Although &lt;em&gt;Cakile maritima&lt;/em&gt; has a high antioxidant capacity, it is yet to be tested for the ability to inhibit the growth of the bacterial triggers of autoimmune inflammatory diseases. &lt;strong&gt;Methods: &lt;/strong&gt;&lt;em&gt;C. maritima&lt;/em&gt; solvent extracts were analysed for antioxidant capacity by the DPPH free radical scavenging assay. Growth inhibitory activities against bacterial species associated with initiating rheumatoid arthritis, ankylosing spondylitis and multiple sclerosis were determined by disc diffusion assay and quantified by MIC determination. Toxicity was determined by &lt;em&gt;Artemia franciscana&lt;/em&gt; bioassay. &lt;strong&gt;Results:&lt;/strong&gt; All &lt;em&gt;C. maritima&lt;/em&gt; solvent extracts displayed good DPPH radical scavenging activity, although the ethyl acetate extract was particularly potent with an IC&lt;sub&gt;50&lt;/sub&gt; values of 3.4 &amp;mu;g/mL. The other extracts also had significant radical scavenging activity, with IC&lt;sub&gt;50&lt;/sub&gt; between 4.7 and 13.6 &amp;mu;g/mL. The bacterial growth inhibitory activity of the extracts correlated with their free radical scavenging activity. The ethyl acetate extract displayed the most potent growth inhibitory activity against most bacterial species. This extract was particularly potent against&lt;em&gt; Proteus mirabilis&lt;/em&gt;, &lt;em&gt;Proteus vulgaris&lt;/em&gt; and &lt;em&gt;Pseudomonas aeruginosa&lt;/em&gt; (MIC values of 431, 559 and 777 &amp;mu;g/mL, respectively). The hexane extract was also a potent inhibitor of the &lt;em&gt;Proteus&lt;/em&gt; spp., (MIC of approximately 500-800 &amp;mu;g/mL). The ethyl acetate extract also inhibited &lt;em&gt;Klebsiella pneumoniae&lt;/em&gt; growth, albeit with higher MIC&amp;rsquo;s (approximately 1500 &amp;mu;g/mL). All other &lt;em&gt;C. maritima&lt;/em&gt; extract-bacteria combinations generally resulted in mid-low potency inhibition. All of the extracts were determined to be nontoxicin with the &lt;em&gt;Artemia franciscana &lt;/em&gt;bioassay, with LC&lt;sub&gt;50&lt;/sub&gt; values substantially &amp;gt;1000 &amp;mu;g/mL. A total of 97 unique mass signals were detected in the &lt;em&gt;C. maritima&lt;/em&gt; ethyl acetate extract by nonbiased GC-MS headspace analysis. A number of terpenoids which may contribute to the therapeutic bioactivities of the extract were putatively identified.&lt;strong&gt; Conclusion:&lt;/strong&gt; The lack of toxicity and the inhibitory activity against microbial triggers of rheumatoid arthritis, ankylosing spondylitis and multiple sclerosis by the &lt;em&gt;C. maritima &lt;/em&gt;ethyl acetate extract indicates its potential in the treatment and prevention of these diseases.&lt;/p&gt;

Despite this, &lt;em&gt;D. leichhardtii&lt;/em&gt; leaf extracts have not been rigorously examined for growth inhibitory properties against many bacteria, including the bacterial triggers of autoimmune inflammatory diseases. &lt;strong&gt;Methods:&lt;/strong&gt; The antimicrobial activity of &lt;em&gt;D. leichhardtii&lt;/em&gt; leaf solvent extracts was investigated by disc diffusion and growth time course assays against a panel of bacterial triggers of autoimmune diseases.

The aqueous and ethyl acetate extracts were also potent bacterial growth inhibitors, albeit with higher MIC values. The antibacterial activity of the methanolic and aqueous &lt;em&gt;D. leichhardtii &lt;/em&gt;leaf extracts were further investigated by growth time course assays which showed significant growth inhibition in cultures of &lt;em&gt;P. mirabilis&lt;/em&gt; and &lt;em&gt;K. pneumoniae &lt;/em&gt;within 1 h of exposure.

However, the high ascorbic acid levels in Kakadu plum fruit may interfere with this activity. &lt;strong&gt;Methods: &lt;/strong&gt;&lt;em&gt;T. ferdinandiana&lt;/em&gt; leaf solvent extracts were investigated by disc diffusion assay against a panel of bacteria known to trigger autoimmune inflammatory diseases.Their MIC values were determined to quantify and compare their efficacies. Toxicity was determined using the&lt;em&gt; Artemia franciscana&lt;/em&gt; nauplii bioassay. Non-targeted HPLC separation of crude extracts coupled to high resolution time-of-flight (TOF) mass spectroscopy with screening against 3 compound databases was used for the identification and characterisation of individual components in crude plant extracts. &lt;strong&gt;Results:&lt;/strong&gt; Methanolic, aqueous and ethyl acetate&lt;em&gt; T. Ferdinandiana&lt;/em&gt; leaf extracts displayed potent antibacterial activity in the disc diffusion assay against the bacterial triggers of rheumatoid arthritis, ankylosing spondylitis and multiple sclerosis. The ethyl acetate extract had the most potent inhibitory activity, with MIC values less than 120 &amp;mu;g/ml against&lt;em&gt; P. mirabilis&lt;/em&gt; and &lt;em&gt;A. baylyi&lt;/em&gt; (both reference and clinical strains). The ethyl acetate extract had similar potency against K. &lt;em&gt;pneumonia&lt;/em&gt;(both reference and clinical strains), but had higher MIC values (2733 &amp;mu;g/ml) against P. &lt;em&gt;aeruginosa&lt;/em&gt;.

However, the high ascorbic acid levels in Kakadu plum fruit may interfere with this activity. &lt;strong&gt;Methods:&lt;/strong&gt; &lt;em&gt;T. ferdinandiana&lt;/em&gt; leaf solvent extracts were investigated by disc diffusion assay against a panel of bacteria known to trigger autoimmune inflammatory diseases.Their MIC values were determined to quantify and compare their efficacies.Toxicity was determined using the &lt;em&gt;Artemia franciscana&lt;/em&gt; nauplii bioassay. Non-targeted HPLC separation of crude extracts coupled to high resolution time-of-flight (TOF) mass spectroscopy with screening against 3 compound databases was used for the identification and characterisation of individual components in crude plant extracts. &lt;strong&gt;Results:&lt;/strong&gt; Methanolic, aqueous and ethyl acetate &lt;em&gt;T. Ferdinandiana&lt;/em&gt; leaf extracts displayed potent antibacterial activity in the disc diffusion assay against the bacterial triggers of rheumatoid arthritis, ankylosing spondylitis and multiple sclerosis. The ethyl acetate extract had the most potent inhibitory activity, with MIC values less than 120 &amp;mu;g/ml against &lt;em&gt;P. mirabilis&lt;/em&gt; and &lt;em&gt;A. baylyi &lt;/em&gt;(both reference and clinical strains). The ethyl acetate extract had similar potency against &lt;em&gt;K. pneumonia &lt;/em&gt;(both reference and clinical strains), but had higher MIC values (2733 &amp;mu;g/ml) against &lt;em&gt;P. aeruginosa&lt;/em&gt;. The methanolic extract was also a potent inhibitor of bacterial growth, with MIC values generally &amp;lt; 1000 &amp;mu;g/ml. In comparison, the water, chloroform and hexane leaf extracts were all substantially less potent antibacterial agents, with MICs values generally well over 1000 &amp;mu;g/ml.
