[Evaluation of chromogenic medium Uriselect4 in urine culture].

We evaluated the performance and the cost of chromogenic medium Uriselect4 agar with regard to the standard medium for the detection and identification of urinary tract pathogens. A total of 503 clinical urine specimens containing leucocytes greater or equal to 104/mL were analysed prospectively, in parallel by two different persons on blood agar (GS) and Uriselect4 according to the manufacturers' instructions. Of the 503 urine specimens tested, 210 gave a positive culture on Uriselect4 versus 181 on GS.
