Role of nalidixic acid in isolation of Salmonella typhimurium strains capable of growth at 48 degrees C.

Current microbiology - 1 Nov 1992

Droffner M L, Yamamoto N

Abstract excerpt

Salmonella typhimurium thermotolerant mutants dependent on the presence of nalidixic acid for growth at 48 degrees C were isolated and designated nalidixic acid-dependent, thermotolerant mutants, naldttl. Genetic mapping revealed that naldttl alleles map within the gyrA gene. When S. typhimurium strain Q was plated in the dark on nutrient agar containing nalidixic acid (20 micrograms/ml) as a photosensitizer and...
