Relative proportions of serovars of Salmonella enterica subsp. enterica found in each animal source (i.e. avian, bovine, fish and swine) in log-scale and corrected by the baseline proportions in the curated subset of Enterobase (see text for details). The present study focusing on adaptation to animal sources (n = 13,635) does not include isolates from environment, composite foods of the retail market and humans, which are considered as vectors of pathogen expositions and exposed susceptible consumers, respectively. The indexes higher and lower than zero represent sources in which serovars are over- and under-represented, respectively. The total effectives and p-values of Chi-square tests of uniformity applied to indexes are in brackets and square brackets, respectively. The serovars are sorted from the lowest (i.e. potentially mono-animal source) to highest (i.e. potentially multi-animal source) p-values. An asterisk stands for less than 20 samples from fish. A double asterisk stands for less than 20 samples from avian, bovine, swine and fish sources
