Systemic candidiasis has become an emerging fungal infection in recent years. Anti-Candida resistance to conventional antifungal agents has subsequently increased. This study reported the chemical composition, antioxidant and anti-Candida activity of Origanum majorana, Artemisia dracunculus, Cymbopogon citrate, Cinnamomum verum and Caryophyllus aromaticus essential oils. Different Candida species, from urine tracts of hospitalized patients, were included to be challenged with understudied essential oils. Chemical compositions were determined using gas chromatography/mass spectroscopy (GC/MS) analysis and antioxidant activity was measured using DDPH assay...

Adult female Guinea worms (Dracunculus spp.) usually are reported to occur singly in the extremities of their hosts, from which they deliver their larvae through fistulae in the host's skin into the water. We visually examined for presence of worms in the fascia of the limbs of skinned carcasses of 184 river otters (Lontra canadensis) harvested in Arkansas, and report observations of cysts on wrists and ankles found on 12 otters. Cysts averaged 15.6 X 24.6 mm in size, were round to oval, and contained masses of up to 19 adult female Dracunculus sp...

Dracunculiasis (Guinea worm disease) is caused by Dracunculus medinensis, a parasitic worm. Approximately 1 year after a person acquires infection from contaminated drinking water, the worm emerges through the skin, usually on a lower limb (1). Pain and secondary bacterial infection can cause temporary or permanent disability that disrupts work and schooling. The campaign to eradicate dracunculiasis worldwide began in 1980 at CDC. In 1986, the World Health Assembly called for dracunculiasis elimination,* and the global Guinea Worm Eradication Program, led by the Carter Center and supported by the World Health Organization (WHO), United Nations Children's Fund, CDC, and other partners, began assisting ministries of health in countries with endemic dracunculiasis...

Dracunculiasis, also named Guinea Worm Disease (GWD), is one of the Neglected Tropical Diseases (NTDs) caused by a parasitic nematode known as Dracunculus medinensis and has been known since antiquity as 'fiery serpent' from Israelites. It is transmitted to humans via drinking contaminated water containing infective copepods. Given, its feasibility for eradication, the Guinea Worm Eradication Program (GWEP) was launched in 1980 with the aim of eradicating the disease. Since its inception, GWEP has made an extraordinary progress in interrupting transmission...

To inform Dracunculus medinensis (Guinea worm) eradication efforts, we evaluated the role of fish as transport hosts for Dracunculus worms. Ferrets fed fish that had ingested infected copepods became infected, highlighting the importance of recommendations to cook fish, bury entrails, and prevent dogs from consuming raw fish and entrails.

Guinea worm disease (GWD) is both a neglected tropical disease and an environmentally driven infectious disease. Environmentally driven infectious diseases remain one of the biggest health threats for human welfare in developing countries and the threat is increased by the looming danger of climate change. In this paper we present a multiscale model of GWD that integrates the within-host scale and the between-host scale. The model is used to concurrently examine the interactions between the three organisms that are implicated in natural cases of GWD transmission, the copepod vector, the human host, and the protozoan worm parasite (Dracunculus medinensis) , and identify their epidemiological roles...

We investigated the cytotoxic and antitumor effects of nine leaf extracts from Artemisia dracunculus (Tarragon). Five extracts were obtained using different organic solvents and four by supercritical CO2. The cytotoxic effects were expressed as IC50 in 100, 80, 80, 100, and 80 μg/mL by respective solvents: hexane, ethyl acetate, acetone, ethanol, and acetonitrile in L5178Y lymphoma cells. For supercritical CO2 extract A, IC50 was 100 μg/mL; for extracts C and D, IC50 was 150 μg/mL. The antitumor activity was assessed through a tumor growth inhibition test that measured ascites fluid volume and tumor cell counts of BALB/c mice (2 × 10(4) cells L5178Y i...

Diabetes mellitus is a common effect of uncontrolled high blood sugar and it is associated with long-term damage, dysfunction, and failure of various organs. In the adult population, the global prevalence of diabetes has nearly doubled since 1980. Without effective prevention and management programs, the continuing significant rise in diabetes will have grave consequences on the health and lifespan of the world population, and also on the world economy. Supplements can be used to correct nutritional deficiencies or to maintain an adequate intake of certain nutrients...

Guinea worm disease, dracunculiasis or dracontiasis, is an ancient disease with records going back over 4500 years, but until the beginning of the 20th century, little was known about its life cycle, particularly how humans became infected. In 1905, Robert Thomas Leiper was sent by the British colonial authorities to West Africa to investigate the spread of Guinea worm disease and to recommend measures to prevent it. While carrying out his investigations, he made important contributions to the aetiology, epidemiology and public health aspects of Guinea worm disease and provided definitive answers to many outstanding questions...

We studied the effect of genetic transformation on biologically active compound (artemisinin and its co-products (ART) as well as sugars) accumulation in Artemisia vulgaris and Artemisia dracunculus "hairy" root cultures. Glucose, fructose, sucrose, and mannitol were accumulated in A. vulgaris and A. dracunculus "hairy" root lines. Genetic transformation has led in some cases to the sugar content increasing or appearing of nonrelevant for the control plant carbohydrates. Sucrose content was 1...

Global eradication of the guinea worm (Dracunculus medinensis) is near, although perhaps delayed a little by the discovery of a transmission cycle in dogs. It is therefore an appropriate time to reflect on the severe impact of this infection on the life of the communities where it was endemic prior to the start of the global eradication programme in 1981. From 1971 to 1974, we conducted a series of unpublished studies on guinea worm in a group of villages in Katsina State, northern Nigeria, where the infection was highly endemic...

Cutaneous leishmaniasis is one of the important skin diseases with diverse clinical manifestations. With an incidence of 0.7-1.3 million cases annually, this disease is often reported from six countries, including Iran. Accordingly, the purpose of this study was to evaluate the anti-leishmanial effect of the three plant hydroalcoholic extracts including fleawort ( Plantago psyllium L.), savory ( Satureja hortensis L.) and tarragon ( Artemisia dracunculus L.) on Leishmania major promastigotes. The hydroalcoholic extract from each plant was extracted and its anti-leishmanial effect was evaluated in different concentrations (100-1000 µg/ml) and at various hours (24, 48 and 72 h)...
