Table 1.
Relative sensitivity and selectivity of BCYEα and MWY media from Xebios or Oxoid for Legionella spp. isolation.
| BCYEα Oxoid | MWY Oxoid | BCYEα Xebios | MWY Xebios | |
|---|---|---|---|---|
| Number (%) plates growing Legionella | 44 (29.7) | 52 (35.1) | 49 (33.1) | 62 (41.9) |
| Sensitivity a | (63) | (74) | (70) | (78) |
| Number (%) plates growing microorganism other than Legionella | 21 (14.2) | 70 (47.3) | 18 (12.2) | 70 (47.3) |
| Selectivity b | (14) | (47) | (12) | (47) |
a Sensitivity was calculated by comparing the number of positive plates for a given medium with the cumulative yield of Legionella spp. from all four media (n = 70). b Selectivity for each media was defined as the number of plates suppressing the growth of organisms that were not Legionella spp. over the total number of plates (n = 148).
