Experimental salmonellosis: hypersensitivity to cell wall lipopolysaccharide and anti-infectious resistance of mice infected with Salmonella.

abstract：:A total of 224 strains were serogrouped by coagglutination (COA) and serotyped by protein I enzyme-linked immunosorbent assay (ELISA). Of these strains, 61 were from patients with disseminated gonococcal infection, 21 were from patients with pelvic inflammatory disease, and 115 were from patients with uncomplicated go...
