The fruit has long been used by the first Australians as a nutritional food and as a medicine and recent studies have reported its potent growth inhibitory activity against a broad panel of bacteria. Despite this, &lt;em&gt;T. ferdinandiana&lt;/em&gt; extracts are yet to be tested for the ability to inhibit the growth of &lt;em&gt;Bacillus anthracis&lt;/em&gt;. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Solvent extracts were prepared using both the fruit and leaf of Kakadu plum. The ability to inhibit the growth of &lt;em&gt;B. anthracis&lt;/em&gt; was investigated using a disc diffusion assay. 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. The most potent extracts were investigated using non-targeted GC-MS head space analysis (with screening against a compound database) for the identification and characterisation of individual components in the crude plant extracts. &lt;strong&gt;Results:&lt;/strong&gt; Solvent extractions of &lt;em&gt;T. ferdinandiana&lt;/em&gt; fruit and leaf displayed good growth inhibitory activity in the disc diffusion assay against &lt;em&gt;B. anthracis&lt;/em&gt;. Fruit ethyl acetate and methanolic leaf extracts were particularly potent growth inhibitors, with MIC values of 451 and 377&amp;mu;g/mL respectively. The fruit methanolic and chloroform extracts, as well as the aqueous leaf extracts also were good inhibitors of &lt;em&gt;B. anthracis&lt;/em&gt; growth, albeit with lower efficacy (MIC values of 1800 and 1414 &amp;mu;g/mL respectively).The aqueous fruit extract and leaf chloroform extracts had only low inhibitory activity. All other extracts were completely devoid of growth inhibitory activity. Furthermore, all of the extracts with growth inhibitory activity were nontoxic in the &lt;em&gt;Artemia fransiscana&lt;/em&gt; bioassay, with LC50 values &amp;gt;1000 &amp;mu;g/mL. Non-biased GC-MS phytochemical analysis of the most active extracts (fruit ethyl acetate and methanolic leaf) putatively identified and highlighted several compounds that may contribute to the ability of these extracts to inhibit the growth of &lt;em&gt;B. anthracis&lt;/em&gt;. &lt;strong&gt;Conclusions: &lt;/strong&gt;The low toxicity of the &lt;em&gt;T. ferdinandiana&lt;/em&gt; fruit ethyl acetate and methanolic leaf extracts, as well as their potent growth inhibitory bioactivity against &lt;em&gt;B. anthracis&lt;/em&gt;, indicates their potential as medicinal agents in the treatment and prevention of anthrax.&lt;/p&gt;

Infections result in exotoxin production, tissue necrosis and unless promptly treated, may result in death. &lt;em&gt;Terminalia ferdinandiana&lt;/em&gt; (Kakadu plum) fruit has documented therapeutic properties as a general antiseptic agent. Fruit extracts have been reported to inhibit the growth of an extensive panel of pathogenic bacteria. Leaf extracts have also been shown to block the growth of several bacterial species associated with autoimmune inflammatory diseases. &lt;strong&gt;Methods:&lt;/strong&gt; &lt;em&gt;T. ferdinandiana&lt;/em&gt; fruit and leaf solvent extracts were investigated for growth inhibitory activity by disc diffusion assay against a clinical strain of &lt;em&gt;Clostridium perfringens&lt;/em&gt;. 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. Active extracts were analysed by non-targeted HPLC-QTOF mass spectroscopy (with screening against 3 compound databases) for the identification and characterisation of individual components in the crude plant extracts. &lt;strong&gt;Results:&lt;/strong&gt; Methanolic and aqueous &lt;em&gt;T. ferdinandiana&lt;/em&gt; fruit and leaf extracts, as well as the leaf ethyl acetate extract, displayed growth inhibitory activity in the disc diffusion assay against &lt;em&gt;C. perfringens&lt;/em&gt;. The leaf extracts were generally more potent growth inhibitors than the corresponding fruit extracts, although the aqueous fruit extract had substantially greater efficacy than the aqueous leaf extract. The methanolic and ethyl acetate leaf extracts were particularly potent growth inhibitors, with MIC values of 206 and 117 &amp;mu;g/ml respectively. The fruit methanolic extract also displayed good efficacy, with an MIC of 716 &amp;mu;g/ml. In contrast, the chloroform and hexane extracts of both fruit and leaf were completely devoid of growth inhibitory activity. All &lt;em&gt;T. ferdinandiana &lt;/em&gt;extracts were either nontoxic or of low toxicity in the Artemia fransiscana bioassay. Non-biased phytochemical analysis of the methanolic and ethyl acetate leaf extracts revealed the presence of high relative levels of a diversity of galloand ellagi- tannins.&lt;strong&gt; Conclusion: &lt;/strong&gt;The low toxicity of the &lt;em&gt;T. ferdinandiana &lt;/em&gt;extracts and the potent growth inhibitory bioactivity of the leaf methanolic and ethyl acetate extracts against &lt;em&gt;C. perfringens&lt;/em&gt; indicates their potential as medicinal agents in the treatment and prevention of clostridial myonecrosis and enteritis necroticans. Metabolomic profiling studies indicate that these extracts contained a diversity of tannins.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">144</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mitchell Henry Wright,&lt;sup&gt;1&lt;/sup&gt; Joseph Sirdaarta,&lt;sup&gt;1,2&lt;/sup&gt; Ben &lt;/strong&gt;&lt;strong&gt;Matthews,&lt;sup&gt;3&lt;/sup&gt; &lt;/strong&gt;&lt;strong&gt;Anthony Carlson Greene,&lt;sup&gt;1&lt;/sup&gt; Ian Edwin Cock,&lt;sup&gt;1,2*&lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
