Persistence, Seasonal Dynamics and Pathogenic Potential of Vibrio Communities from Pacific Oyster Hemolymph
Figure 1
Temporal variation in the amount of Vibrio bacteria in oyster hemolymph (HL).
Quantification of total Vibrio spp. (open circles and triangles) isolated from oyster hemolymph stemming from the four transplant groups (origin_site), i.e. DB_DB, DB_OW, OW_DB, OW_OW. Blue lines represent oysters assayed in site OW and black lines represent oysters assayed in site DB. Solid lines show oyster origin DB, while dashed lines show oyster origin OW. Water temperature is shown on the secondary y-axis (full circles, dotted line). The area shaded in grey marks the spawning period. Different letters indicate significant differences according to Tukey HSD post hoc test. Pi charts show relative proportion of Vibrio isolates by phylogenetic association based on 99% similarity by BLASTN analysis in each sampling month. Color codes correspond to those in Figure 2.
