Virulence comparisons of Aspergillus nidulans mutants are confounded by the inflammatory response of p47phox-/- mice.

abstract：:Colony variants of Neisseria gonorrhoeae differ in their interactions with eucaryotic cells. When gonococci were cultivated with HeLa cell monolayers, the opacity phenotype (Op) became increasingly dominant in the subpopulation of organisms which adhered to the HeLa cells. Once bound, Op organisms displayed very low l...
