“…Overall, the results of this study represent further evidence of the importance to exploit long sequencing methods to study the plasmid sequences and structure variation, as they are helpful to avoid some of the challenges raised by the study of mosaic plasmids (Pesesky M., et al, 2019). pESI-like has been described in S. Infantis worldwide, e. g. in Israel (Aviv et al, 2014), Italy (Franco et al, 2015), United States (Tate et al, 2017), Switzerland (Hindermann et al, 2017), Japan (Yokoyama et al, 2015), Hungary (Szmolka et al, 2018), Brazil (dos Santos et al, 2021) and Turkey (Kürekci et al, 2021). With few exceptions, in these studies the characterization of the plasmids was done using short reads sequencing, and the results indicated a less diversity between them compared to what has been observed when the plasmids were fully resolved.…”
