| Abstract |
The heavy metal cadmium (Cd) is a hazardous pollutant that exerts various toxic effects on aquatic animals. The biomagnifying effects of this non-essential element in the food chain also pose threats to human health. In this study, the protective effect of a dietary probiotic supplementation, Lactobacillus plantarum CCFM8610, on the intestinal microbiota and physiological conditions of Nile tilapia (Oreochromis niloticus) exposed to waterborne Cd was evaluated. Two hundred fish were divided into four groups, i.e., control, probiotic-only, Cd-only and Cd-plus-probiotic. The fish were exposed to waterborne Cd at a level of 1 mg L(-1) for 4 weeks and the probiotic was administered twice daily at 10(8) CFU g(-1) in the fish diet. Waterborne Cd exposure caused a profound decline in the gut microbial diversity and marked alterations in the composition of the microbiota. Dietary supplementation with L. plantarum CCFM8610 reversed the changes in the intestinal microbiota composition in the Cd-exposed fish and reduced the abundance of Flavobacterium and Pseudomonas. Compared with the Cd-only group, the probiotic treatment significantly promoted growth performance and prevented the death of the Cd-exposed fish. L. plantarum CCFM8610 supplementation also decreased Cd accumulation and alleviated oxidative stress in the tissues, and reversed the alterations in hemato-biochemical parameters in the blood of fish. The results suggest that L. plantarum CCFM8610 can be considered a safe dietary supplement for the prevention of Cd-exposure-induced problems in aquaculture and food safety. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 March 2017.
All research outputs
#15,416,191
of 22,925,760 outputs
Outputs from Antonie van Leeuwenhoek
#1,400
of 2,031 outputs
Outputs of similar age
#256,462
of 420,925 outputs
Outputs of similar age from Antonie van Leeuwenhoek
#14
of 22 outputs
Altmetric has tracked 22,925,760 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,031 research outputs from this source. They receive a mean Attention Score of 3.6. This one is in the 25th percentile – i.e., 25% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 420,925 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 22 others from the same source and published within six weeks on either side of this one. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
