Abstract

Bacterial communities are called another “organ” for aquatic animals and their important influence on the health of host has drawn increasing attention. Thus, it is important to study the relationships between aquatic animals and bacterial communities. Here, bacterial communities associated with Litopenaeus vannamei larvae at different healthy statuses (diseased and healthy) and growth stages (i.e. zoea, mysis and early postlarvae periods) were examined using 454-pyrosequencing of the 16S rRNA gene. Bacterial communities with significant difference were observed between healthy and diseased rearing water, and several bacterial groups, such as genera Nautella and Kordiimonas could also distinguish healthy and diseased shrimp. Rhodobacteraceae was widely distributed in rearing water at all growth stages but there were several stage-specific groups, indicating that bacterial members in rearing water assembled into distinct communities throughout the larval development. However, Gammaproteobacteria, mainly family Enterobacteriaceae, was the most abundant group (accounting for more than 85%) in shrimp larvae at all growth stages. This study compared bacterial communities associated with healthy and diseased L. vannamei larvae and rearing water, and identified several health- and growth stage-specific bacterial groups, which might be provided as indicators for monitoring the healthy status of shrimp larvae in hatchery.

FIGURE 2 Boxplots of bacterial diversity and richness in WH, WD, SH, and SD. The top and bottom boundaries of each box show the 75th and 25th quartile values, respectively. The black lines within each box represent 50th quartile values. Ends of the whiskers indicate the lowest and highest values. The different letter above the boxes indicate that there is significant difference between groups (P < 0.05). (A,B) Chao 1 and Shannon indices used to estimate bacterial diversity for each group; (C), OTUs used to determine species richness. WH: water samples from ponds with healthy shrimps, WD: water samples from ponds with diseased shrimps, SH: shrimp samples from ponds with healthy shrimps, SD: shrimp samples from ponds with diseased shrimps.

Circle and triangle represent shrimp and water samples, respectively. Blue, purple, and red represent zoea, mysis, and postlarvae stages, respectively. Green: rearing water before larvae were released into pond. Symbols filled and unfilled color indicated healthy and diseased, respectively.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
