Cadmium affects intestinal health of Haliotis Diversicolor

Because of its high nutritional value, Haliotis Diversicolor is increasingly popular. Antibiotics are often used to reduce the fatality rate of Haliotis Diversicolor, but at the same time increase antibiotic resistance. In addition, with the development of industry, cadmium pollution in water is becoming more and more serious. While heavy metal resistance genes and antibiotic resistance genes are often located on the same mobile genetic element. In this study, only cadmium selective pressure was applied to Haliotis Diversicolor (a control group, low, medium and high concentration groups) to study the effects of cadmium on intestinal microflora and antibiotic resistance. Intestinal contents of Haliotis Diversicolor were detected by 16S rRNA sequencing.
