Abstract
Summary
Bacteriostatic and bactericidal concentrations of 6 sulfonamides in vitro after 2, 4 and 7 days for a resistant strain of Shigella paradysenteriae Flexner and 2 resistant strains of Shigella sonnei show that: The 3 resistant strains were not resistant to sulfapyrazine; the Sonnei (Ch) strain was in addition, not resistant to sulfacetamide; the Sonnei (Ma) strain was also not resistant to sulfacetamide according to the bactericidal concentrations, but as judged by the bacteriostatic concentrations was more resistant to sulfacetamide than was its parent strain; these 3 strains were quite resistant to the other sulfonamides.
