The early diagnosis of urinary tract infection and its rational therapy are dependent upon the qualitative and quantitative urine culture.1,5 The unreliability of symptoms and the inconstancy of pyuria5,15 have resulted in the emergence of persistent bacteriuria as the most reliable index of urinary infection.12 However, if large populations are to be screened for asymptomatic urinary infection,6,8,12 a method less cumbersome and less expensive than the standard pour-plate technique is needed.7,11 A simple method recently described by Bailey and Scott in their text,10 but earlier assessed by Hoeprich,11 has been in routine use in the private pediatric practice of one of us, (M. F. R.) for over two years.
It is the purpose of this report to present the loop-surface agar method as a simple, accurate, inexpensive technique for screening large populations for bacteriuria and to suggest its suitability for office as well
