FIG. 1.

Survival curves of representative clinical and poultry-derived C. jejuni strains at 4°C. Poultry isolates were CJ1 (□), CJ3 (◊), CJ7 (▵), CJ33 (×), and CJ52 (○). Clinical isolates were CJ17 (■), CJ19 (⧫), CJ22 (▴), and CJ26 (●). Results for CJ3 on days 12 and 14 were below the limit of detection, 10 CFU/ml (1 in log₁₀ scale). Data shown are means from duplicate plates in a representative experiment and were collected as described in Materials and Methods.
