Sensitivity of RapidBac in bacteriuric samples by uropathogena
| Uropathogen | No. of bacteriuric samples (% significant bacteriuria) | No. of RapidBac-positive samples (sensitivity [%]) |
|---|---|---|
| Enterobacteriaceae | 269 (94) | 243 (90) |
| E. coli | 225 (79) | 207 (92) |
| Proteus spp. | 11 (4) | 9 (82) |
| Klebsiella spp. | 21 (7) | 19 (90) |
| Other Enterobacteriaceaeb | 13 (5) | 11 (85) |
| Pseudomonas spp. | 3 (1) | 0 (0) |
| Acinetobacter spp. | 1 (<1) | 1 (100) |
| Staphylococcus saprophyticus | 16 (6) | 2 (12)c |
a
There were a total of 285 bacteriuric samples. Uropathogen categories are not mutually exclusive. Five samples had two identified uropathogens; these were included under each respective uropathogen category.
b
Other Gram-negative Enterobacteriaceae include Citrobacter spp. (n = 5), Enterobacter spp. (n = 8), and Serratia spp. (n = 1).
c
Two samples with S. saprophyticus also contained Gram-negative bacteria. It is presumed that the RapidBac test was positive due to the presence of the Gram-negative organism.
