Regulation of innate immune response to Candida albicans infections by αMβ2-Pra1p interaction.

abstract：:Comparative studies on the virulence of two strains of Pseudomonas aeruginosa isolated from otic pus and mink pneumonic lesion, respectively, were made by means of intranasal inoculation in mink. The minimal lethal dose of the former (strain NC-5, highly virulent for mice) was 10(10), and that of the latter (strain No...
