Fig 1.
Distribution of S. enterica isolates by serovars (A) and sequences type (B) identified from 818 isolates collected in Mexico.
Fig 2.
Relationship between serovars and sequence types of S. enterica.
The heat map shows the frequency of each ST associated with specific serovars.
Fig 3.
Minimum spanning tree illustrates relationships between sequence types and serovars of S. enterica.
The diagram maps genetic relatedness based on shared sequence variants, highlighting both dominant STs and the genetic diversity within serovars.
Fig 4.
Antimicrobial resistance gene profile of S. enterica serovars.
Resistance genes associated with aminoglycosides, β-lactams, fluoroquinolones, sulfonamides, and tetracyclines across major serovars. The numbers within the squares indicate the number of genomes carrying specific AMR genes.
Fig 5.
Correlation between phylogenetic analysis, serovars, and sequence types of S. enterica.
This circular phylogenetic tree highlights genetic clustering of serovars and their associated STs. Outer circles represent the origin of isolates, showcasing the diversity of contamination sources contributing to the genetic structure of S. enterica in Mexico.
