Other genes present in the majority of the isolates were pfoA (perfringolysin O), tpeL (toxin perfringens large), and cpb2 (beta2 toxin), which are protein coding genes involved in gastrointestinal outcomes and gangrene (Coursodon et al., 2012; Bueschel et al., 2013; Chen and McClane, 2015), and the sialidases nanH, nanI y nanJ, which play an important role in colonization and immunomodulation (Figure 4A). This evidence concerns the gene CPB2 and gangrene.
