Toxoplasma gondii: characterization of a mutant resistant to sulfonamides.

Experimental parasitology - 1 May 1992

Pfefferkorn E R, Borotz S E, Nothnagel R F

Abstract excerpt

Sulfadiazine was a potent inhibitor of the in vitro growth of Toxoplasma gondii, although it had little effect during the first 24 hr of treatment. A mutant parasite (R-SulR-5) with a 300-fold increase in sulfadiazine resistance was selected by a combination of chemical mutagenesis and growth in gradually increased sulfadiazine concentrations. This mutant was completely cross-resistant to several other...
