Viruses, Bacteria and Fungal Infections

Olive Leaf and Viruses, Bacteria, and Gungal infections:

1. The olive leaf extract exhibits antiviral activity against viral haemorrhagic septicaemia rhabdovirus (VHSV): “Therefore, we propose that O. europaea could be used as a potential source of promising natural antivirals, which have demonstrated to lack impact on health and environment. In addition, Ole could be used to design other related antiviral agents.”

2.  Anti-HIV activity of olive leaf extract (OLE) and modulation of host cell gene expression by HIV-1 infection and OLE treatment: “Treatment with OLE reverses many of these HIV-1 infection-associated changes. Treatment of HIV-1-infected cells with OLE also up-regulates the expression of the apoptosis inhibitor proteins IAP1 and 2, as well as the calcium and protein kinase C pathway signaling molecules IL-2, IL-2Ralpha, and ornithine decarboxylase ODC1.”

3. In vitro antimicrobial activity of olive leaves: “We investigated the antimicrobial effect of olive leaves against bacteria and fungi. The microorganisms tested were inoculated in various concentrations of olive leaf water extract. Olive leaf 0.6% (w/v) water extract killed almost all bacteria tested, within 3 hours.”

7. Activity assessment of Tunisian olive leaf extracts against the trophozoite stage of Acanthamoeba: “Trophozoite growth was inhibited by all the tested extracts…”

8.  Antimicrobial activity of commercial Olea europaea (olive) leaf extract: “Given this specific activity, olive leaf extract may have a role in regulating the composition of the gastric flora by selectively reducing levels of H. pylori and C. jejuni.”

9.  Phenolic compounds and antimicrobial activity of olive (Olea europaea L. Cv. Cobrançosa) leaves: “At low concentrations olive leaves extracts showed an unusual combined antibacterial and antifungal action, which suggest their great potential as nutraceuticals, particularly as a source of phenolic compounds.”

10. Hydroxytyrosol expresses antifungal activity in vitro: “Hydroxytyrosol (HT) is a potent antioxidant found in olive oil and leaves. Using several in vitro approaches, we tested antifungal activity of HT. HT showed broad spectrum of antifungal activity against medically important yeasts…”

11. Leishmanicidal activity assessment of olive tree extracts: “Leishmaniasis, a protozoan parasitic disease that remains a major worldwide health problem with high endemicity in developing countries, is prevalent around the Mediterranean basin. High cost, systemic toxicity, and diminished efficacy due to development of parasite resistance are the serious drawbacks of current treatment options… Oleuropein and hydroxytyrosol exhibited the best inhibitory effect among the natural products tested in both stationary and middle logarithmic phase promastigotes of L. infantum, L. donovani, and L. major. Similarly, oleuropein and hydroxytyrosol demonstrated the highest selectivity index ratio against L. donovani amastigotes that parasitize J774A.1 macrophages…Three days after treatment termination, the spleen parasitic burden was reduced >80%. Of interest, this effect of oleuropein persisted and was even enhanced 6 weeks after the termination of the treatment, as determined by parasite depletion of >95% in liver and spleen. These findings contribute to the potential development of natural products as effective drugs against parasites of the Leishmania genus, with low cost and diminished cytotoxicity.”

12. Antioxidant and antimicrobial activities of individual and combined phenolics in Olea europaea leaf extract: “These results show that the combination of olive leaf extract phenolics possessed antioxidant and antimicrobial activities. This study indicates that olive leaf extract might be a valuable bioactive source, and would seem to be applicable in both the health and medical food.”
