Genomic quality control and geo-temporal distribution of Chinese source Salmonella enterica serovar Gallinarum (S. Gallinarum). (a–c) Quality control of the assembled genome. Where a-c represents GC%, N50, and genome length, respectively. (d) BUSCO analysis showed 98.5% gene completeness in genomes of all three strains, with only 1.4% missing gene orthologs. (e) Geographical distribution of S. Gallinarum in China. The colour indicates the number of isolated bacterial within the province. (f) Temporal distribution of S. Gallinarum in China. Larger circles represent more S. Gallinarum. (g) Correlation analysis was conducted between the number of S. Gallinarum isolates collected from different provinces in China and each province’s total GDP, population size, number of poultry slaughtered, and egg production. The figure depicts points representing individual provinces. The x-axis indicates the number of S. Gallinarum isolates included in the dataset, while the y-axis displays the values for each province’s total GDP, population size, number of poultry slaughtered, and egg production, respectively.
