An epidemiological survey investigating rotavirus infection in children was undertaken in the coastal region of Tunisia from January 2000 through September 2003. A total of 309 fecal specimens were screened by enzyme-linked ...

Comparative study of Bacillus thuringiensis Cry1Ia and Cry1Aa delta-endotoxins : activation process and toxicity against Prays oleae

Dammak, Mariam; Tounsi, Slim; Rousis, Souad; Jaoua, Samir ( Elsevier Inc. , 2010 , Article)

Cry1Ia and Cry1Aa proteins exhibited toxicities against Prays oleae with LC(50) of 189 and 116 ng/cm(2), respectively. The ability to process Cry1Ia11 protoxin by trypsin, chymotrypsin and P. oleae larvae proteases was ...

Involvement of oxidative stress and growth at high cell density in the viable but nonculturable state of Photorhabdus temperata ssp. temperata strain K122

Jallouli, Wafa; Zouari, Nabil; Jaoua, Samir ( Elsevier Ltd , 2010 , Article)

Photorhabdus temperata ssp. temperata strain K122 represents a promising source of bioinsecticide. When cultured in an optimized medium, P. temperata exhibited restricted survival in terms of colony-forming ability on solid ...

Evidence of the Involvement of E358, A498 and C571 of a New Cry1Ac δ-endotoxin of Bacillus thuringiensis in its High Insecticidal Activity Against Ephestia kuehniella

Saadaoui, Imen; Miled, Nabil; Jaoua, Samir ( Humana Press Inc , 2010 , Article)

A new cry1Ac-type gene was cloned from Bacillus thuringiensis strain BLB1, sequenced and expressed. The deduced amino acid sequence of the polypeptide has a predicted molecular mass of 132.186 kDa. The amino acid sequence ...
