Role of Conjugative Plasmid in The Virulence of locally Isolated Salmonella typhimurium

     In this study, one hundred stool samples were collected from children under age of five years of both sexes suffering from diarrhea infection cases from Al-Kadhimia and Al-Elwia hospitals in Bagdad governorate, and from Ibn-Ghaswan hospital in Basra governorate. Stool samples were cultured on Salmonella-Shigella agar plates, and then 38 bacterial isolates were obtained. All these isolates were subjected to morphological, microscopically examinations and biochemical tests.

Studying the effect of Lactobacillus acidophilus on the pathological effect of Proteus mirabilis in mice

Proteus mirabilis, a common cause of nosocomial and catheter associated urinary tract infection, colonize the bladder and ascends the ureters to the proximal tubules of kidneys, leading to the development of acute pyelonephritis (Angela et al., 2003). Adherence of P. mirabilis to uroepithelial tissue may be an important virulence determinant in these infections because most proteus strains adhere to desquamated uroepithelial cells (Susan et al., 1986). Also p.

In vivo and in vitro studies on the production of some secondary metabolites from Salvia officinalis L. and their antibacterial activity

 

          In an attempt to increase the production of some secondary metabolites in tissue cultures of Salvia officinalis compared to the intact plant, several experiments were carried out. Callus was induced and maintained on MS medium supplemented with 0.5 mg/l kinetin and 0.05 mg/l 2,4-D from leaf and stem explants. NaCl was added to the culture medium at concentrations 50 or 100 mM as a stress agent for elicitation.
