Over the past decades, considerable advances have been made in understanding the crucial role and the regulation of sucrose metabolism in plants. Among the various sucrose-catabolizing enzymes, alkaline/neutral invertases (A/N-Invs) have long remained poorly studied. However, recent findings have demonstrated the presence of A/N-Invs in various organelles in addition to the cytosol, and their i...

In Enterobacteriaceae, the RNA chaperone Hfq mediates the interaction of small RNAs with target mRNAs, thereby modulating transcript stability and translation. This post-transcriptional control helps bacteria adapt quickly to changing environmental conditions. Our previous mutational analysis showed that Hfq is involved in metabolism and stress survival in the enteropathogen Yersinia enterocoli...

Direct quantification of mRNA from Salmonella sp. seeded for 1 h to soil and chicken manure was accomplished using magnetic capture hybridization as a purification technique. This detection strategy targeted the invA gene present in Salmonella sp. After cell lysis, phenol/chloroform purification and isopropanol precipitation, the RNA extract was combined with the hybridization probe conjugated ...

The quantity of seafood imported and produced by domestic aquaculture farming has increased. Recently, it been reported that multidrug-resistant (MDR) Salmonella Typhimurium may be associated with seafood. However, information is limited to the antimicrobial resistance, virulence properties, genetic diversity S. recovered from This study investigated isolated catfish, shrimp, tilapia. A total 1...

Salmonella typhimurium induced massive uptake of extracellular fluid in epithelial cells in the form of macropinosomes. The appearance of macropinosomes in the infected cell was related to the induction of membrane ruffling during bacterial invasion. A noninvasive S. typhimurium invA mutant did not trigger such effects in the host cell. Similarly, S. typhimurium invA mutants that invaded via th...

Le sésame constitue le deuxième produit d’exportation agricole au Burkina Faso mais sa qualité n’est pas toujours satisfaisante à cause de la présence d’impuretés et parfois microorganismes pathogènes notamment les salmonelles. La présente étude a pour objectif d’évaluer prévalence des salmonelles dans ses produits dérivés. Au total, 107 échantillons dont 73 graines 34 dérivés (biscuits, croque...
