Abstract

SUMMARY

The metabolic activities of faecal and urinary strains of and were compared. Regardless of origin, the generation time of strains in urine was approximately twice as long as that of the strains. Urease synthesis was constitutive in strains but required induction with urea in the strains. In the presence of urea, the strains liberated ammonia more rapidly and produced alkaline conditions more quickly than strains, although they synthesized much less urease. These characteristics may place strains at a disadvantage in comparison with strains in their ability to cause urinary tract infections.
