Comparative Study on the Fecal Microbiota Diversity of Black-Headed Gull and Magpie
Total DNA from fecal samples were extracted and the V3～V4 hypervariable region of the 16S rRNA sequence was amplified to assess the potential risk of bird-to-human pathogen transmission in differ-ent bird species.Gut microbiota characterizations were determined with high-throughput sequencing and the followed bioinformatical analyses.The results show remarkable differences in the fecal microbiota be-tween black-headed gulls and magpies.Firmicutes and Proteobacteria are the primary bacterial phyla in black-headed gull and magpie feces,respectively.Catellicoccus is the predominant genus in black-headed gull feces,and the average abundance is 65.5％.The detective rate of Campylobacter in black-headed gull feces is 100％,and the average abundance is 1.2％.But in magpie feces,the detective rate is 55.6％,and the average abundance is 0.019％.This suggests that Campylobacter is widespread in the population of black-headed gull in Qingdao,and the safety risk of exposure to black-headed gulls is higher than magpies.
