Virulence parameter for L. monocytogenes inlA subgroups using the conditional probability modeling approach
| Molecular subgroup | r value (log)b | Confidence interval (95%)b |
|---|---|---|
| inlA without PMSCs | −8.13 (−8.04) | −8.68-−7.58 (−8.59-−7.50) |
| inlA with PMSCs | −10.68 (−11.29) | −11.06-−10.30 (−11.59-−10.98) |
| inlA with PMSCnot4 | −8.88 (−9.45) | −10.01-−7.76 (−10.54-−8.36) |
| inlA with PMSC4 | −11.30 (−12.10) | −INF-NANc (−12.50-−11.70) |
| Combined modela | −9.94 | −9.66-−10.23 |
a
Values for L. monocytogenes regardless of subtype.
b
Values were obtained based on human illness and clinical isolate data from the MD and CA FoodNet sites (outside parentheses) and from multiple U.S. states (inside parentheses).
c
INF, infinite; NAN, not a number. These outputs were obtained in simulation because 0 was sometimes obtained in the distribution of the number of cases attributed to isolates with inlA PMSC4.
