Pig gut microbiome Metagenome
In this study, we compared antibiotic resistance genes prevalence and microbial diversity in faeces of organic and conventional pigs originating from 4 different European countries (Sweden, Denmark, France and Italy). We expected that the prevalence of tested antibiotic resistance genes would be higher in the conventionally grown pigs due to a more frequent antibiotic use while microbial diversity might by higher in organic pigs due to their higher exposure to environmental microbiota sources. Unlike expectation, there were no significant differences between the prevalence of selected antibiotic resistance genes in microbiota of organic or conventional pigs.
