The horizontal axis EPZ015938 in vivo represents 73.85% of the total inertia, which is responsible for the major separation. According to this analysis, the subgroup distribution was similar for cows, goats and sheep and for pigs and humans (Figure 2). A sewage sample was included in the CA (Figure 2). This sample included the following subgroups: A0 (one strain), A1 (five

strains), D1 (four strains) and D2 (two strains). As expected, this subgroup distribution was similar to the one found for humans (Figure 2). Figure 2 Correspondence analysis using the contingence table of subgroup distribution among the hosts analyzed. Subgroups and samples that Lazertinib price are similar fall close. Eigenvalues are 0.47575 for the horizontal axis and 0.12813 for the vertical axis. The horizontal axis is responsible for 73.85% of the total inertia and the vertical axis for 19.89%. The CA using the genetic markers distribution resulted in a bidimensional representation that can explain

100% of the total inertia (Figure 3), being the horizontal axis responsible for 92.04% of it. According to this analysis, the genetic markers distribution was similar for cows, goats and sheep and for humans, chickens and pigs. The sewage sample, in which six strains presented the chuA gene, five the yjaA gene and two the TspE4.C2 fragment, was plotted near the human find more sample (Figure 3). Figure 3 Correspondence analysis using the contingence table of phylogenetic group distribution among the hosts analyzed. Phylo-groups and samples that are similar fall close. Eigenvalues are 0.33431 for the horizontal axis and 0.06708 for the vertical axis. The horizontal axis is responsible for 82.54% of the total inertia and the vertical axis for 16.56%.

The discrimination power of the phylogenetic groups A, B1, B2 and D was also tested using CA (Figure 4). According to this analysis, the bidimensional representation of the phylo-groups relative abundance can explain 99.1% of the total inertia, being the horizontal axis responsible for 82.54% of it. This analysis revealed that the phylo-group distribution among cows, goats and sheep, which presented a predominance of strains Amobarbital of the B1 group, was similar. Humans, chickens and pigs remained separated. E. coli strains isolated from two Rivers, Jaguari and Sorocaba, located in the State of São Paulo, Brazil, and previously analyzed by Orsi et al. [23], were also included in this CA analysis (data not shown). The strain composition of the Jaguari River included 42 strains of group A, 13 strains of group B1 and six strains of group D. The Sorocaba River included 45 strains of group A, 14 strains of group B1, one strain of group B2 and eight strains of group D. The strains distribution among the phylo-groups, from both rivers, was similar to the one observed for chickens and pigs. The sewage sample was also included in this CA and once again, this sample was similar to humans (Figure 4).
