FIG. 3.

Mean log₁₀ number (±SE; n = 8 animals) of total (intact) Vibrio campbellii bacteria g⁻¹ tissue recovered from Crassostrea virginica at 0, 1, 4, and 24 h after receiving an injection containing 1 × 10⁵ Vibrio campbellii bacteria. Oysters were exposed to either fully air-saturated (normoxic) or HH seawater for 4 h before receiving the injection containing bacteria and remained under these conditions for the remainder of the experiment (up to 24 h postinjection). Significant differences between normoxia- and HH-exposed animals at each time point were assessed by analyzing rank-transformed culturable bacterial data by two-way ANOVA using the Holm-Sidak method and are indicated by asterisks, whereas significant differences between each time point within normoxia- and HH-exposed animals are indicated by different upper- and lowercase letters, respectively.
