Conservation of stored food using plant's extracts. Effect of oregano (Origanum vulgaris) essential oils on the reproduction and development of flour moth (Ephestia kuehniella).

In the search for effective methods of biological control of stored products insect-pests, the essential oil of Origanum vulgaris was extracted using Clevenger apparatus and tested on reproduction and mortality of flour moth Ephestia kuehniella. Bio-insecticide works with a double action mechanism; administered by inhalation in pupae, essential oil affects their pupal development. It also disrupts the reproduction of exuviated adults by extending the preoviposition period and reducing the period of egg laying and fecundity because fecundated females cannot live more than four days compared to control group.

[Investigation and analysis of an outbreak of cutaneous leishmaniasis in Ksar Ouled Dabbab, Tataouine (Tunisia), 2012-2013].

Unlabelled: Zoonotic cutaneous leishmaniasis (ZCL), due to Leishmania major, and chronic CL, due to L. tropica, are endemic in the governorate (administrative subdivision) of Tataouine (southeast Tunisia). This study aims to analyze epidemiologic, clinical, parasitologic, and entomologic data collected during the 2012-2013 epidemic in Ksar Ouled Dabbab (KOD).

Association of GST genes polymorphisms with asthma in Tunisian children.

Background: A positive association between genetic polymorphism and asthma may not be extrapolated from one ethnic group to another based on intra- and interethnic allelic and genotype frequencies differences.

Objective: We assessed whether polymorphisms of GST genes (GSTM1, GSTT1, and GSTP1) are associated with asthma and atopy among Tunisian children.

Methods: 112 unrelated healthy individuals and 105 asthmatic (73 atopic and 32 nonatopic) children were studied.
