        This work aimed to study the effect of some probiotic microorganisms on fungi causing tinea pedis disease.

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.

This study was aimed to alter the ability of Pseudomonas aeruginosa H3 in alginate production by using some physical and chemical mutagens. Physical mutagenesis were UV radiation and laser mutagens. Chemical mutagenes were N-methyl-N-nitro-N-nitrosoguanidine (MNNG) and Mitomycin C.
