Analysis of cells of the mononuclear phagocyte series in experimental mycobacterial granulomas by monoclonal antibodies.

abstract：:Pseudomonas aeruginosa utilizes a number of distinct pathways to secrete proteins that play various roles during infection. These include the type II secretion system, which is responsible for the secretion of the majority of exoproducts into the surrounding environment, including toxins and degradative enzymes. In co...
