Food-borne diseases, caused by the pathogenic bacteria, are highly prevalent in the world. Salmonella is one of the most important bacterial genera responsible for this. Salmonella Enteritidis (SE) is one of the non-typhoid Salmonellae that can be transmitted to human from poultry products, water, and contaminated food. In recent years, new and rapid detection methods such as enzyme-linked immu...

background salmonella spp. is the major bacterial pathogen in poultry and is responsible for significant economic losses of the poultry industry in many parts of the world. among salmonella spp., salmonella gallinarum and s. pullorum are the most common causative agents of chicken salmonellosis resulting in high mortality and morbidity. objectives the aim of this study was to identify s. gallin...

Cronobacter sakazakii is an opportunistic nosocomial and foodborne pathogen that causes severe infections with high morbidity and mortality rates in neonates, the elderly, and immunocompromised individuals. Little is known about the pathogenesis mechanism of this pathogen and if there are any consequences of C. sakazakii colonization in healthy individuals. In this study, we characterized the m...

Masses of positive and negative parity excited nucleons and hyperons are calculated in quenched lattice QCD using an O(a) improved gluon action and a fat-link clover fermion action in which only the irrelevant operators are constructed with fat links. The results are in agreement with earlier N∗ simulations with improved actions, and exhibit a clear mass splitting between the nucleon and its pa...

Standing modes of light in front of the reflecting surface of silicon modulate the excitation and emission of fluorescent dyes. This effect was used to determine the distance of a biomembrane from an oxidized silicon chip. The membrane of a red blood cell (ghost) was stained with a cyanine dye and attached with poly-lysine to a surface structured with microscopic steps of silicon dioxide on sil...

FL-systems are conditional rewriting systems. They are used for programming (describing) and evaluating (generating) huge 3D virtual environments, such as cities and forests. This paper presents a formal semantics and a dynamic dependency analysis for FL-systems. This analysis allows the characterization of a set of terms which are joinable with the currently rewritten term. Consequently, it is...

conclusions the development of delivery systems into bacteria with an efficacy compatible to that in human use could be a key for the potential utility of sirna for the prophylaxis and treatment of p. aeruginosa-induced hematogenous pulmonary infections in humans. results in quantitative rt–pcr,it was shown that the sirna significantly inhibited the expression of the flagella mrna. filc gene kn...

Foodborne Salmonella infections have become a major problem world wide. Salmonellosis transmitted from fish are quite common. Established quality control measures exist for export oriented fish, none exists for fish consumed locally. This study aimed at characterization of Salmonella isolated from Nile tilapia . The study was carried out in selected beaches along L. Victoria in Western Kenya be...
