FIG. 2.

Bacterial and viral abundances from May 2000 to May 2001. Closed symbols indicate abundances within oysters, and open symbols indicate water-column abundances. (A) Bacterial abundances: water-column total presumptive Vibrio spp. (□), oyster total presumptive Vibrio spp. (▪), and oyster V. parahaemolyticus (•). (B) Viral abundance in the oyster (▴). Values are means of duplicate samples; error bars indicate the ranges of duplicates and are smaller than the width of the symbol if not visible.
