Quantitative urine culture by surface drop method.

A simple drop method for quantitative urine culture was developed and tested in comparison with standard methods for bacterial urinary counts. In a group of 452 urines all yielding Escherichia coli, 74 showed counts of more than 100,000 colonies, and 16 showed counts between 10,000 and 100,000 colonies per ml. Of these 90 urines, 3 of the 16 in the doubtful group were false negative with the dr...

A simplified method for the quantitative bacterial culture of urine.

they were washed with wet swabs and suspended in 1 ml. of nutrient broth and inoculated on blood agar media and into mice. All tested slides failed to produce either culture or infection. A similar experiment was performed with the same type of slides from which mercuric chloride was removed. Both the medium and mice failed to show the presence of B. anthracis. Because unstained areas round the...

Primary culture media for routine urine processing.

It has been recommended that routine microbiological processing of urine specimens include quantitative plating onto blood agar medium along with a selective and differential agar such as MacConkey agar for gram-negative organisms. Few data have been published to justify this combination. To evaluate the validity of this recommendation 2,553 midstream, clean-voided urine samples were quantitati...
