“…We also observed that different toxinotypes grouped within the same clade (Figure 3 and Table 3 ). These findings are similar to those previously reported by Hassan et al and Mehdizadeh Gohari et al and suggest that certain toxin genes are encoded within the accessory genome (Li et al, 2013 ; Hassan et al, 2015 ; Park et al, 2016 ; Mehdizadeh Gohari et al, 2017 ). Our analysis also demonstrates the presence of several major toxins encoded within C. perfringens plasmids (sequences individually retrieved from NCBI nucleotide database), highlighting the potential for toxin gene transfer via HGT (Supplementary Figure 1 ).…”

“…In clade 4 (clearly split from clade 1–3), most isolates were collected from a North American dog and horse C. perfringens haemorrhagic enteritis study (JFP isolates) indicating these isolates might be host- and disease-specific. This supports previous work where these JFP netF -positive isolates were found to cluster closely in a cgMLST tree (Mehdizadeh Gohari et al, 2017 ). Furthermore, the presence of 2 JFP isolates of Swiss origin also clustered in clade 4, which again suggests disease- and host- specificity, but exclusion of geographical linkages.…”

“…Slightly fewer cpe ‐positive C. perfringens strains (23/54) were found compared to netE and netF strains (26/54). In previous studies, cpe , which is present on a tcp ‐conjugative plasmid distinct from the pNetF plasmid, consistently was found in all netF ‐positive C. perfringens strains …”

“…This statement and conclusion is incorrect because NetF-producing C. perfringens has so far only been shown to be an important cause of canine hemorrhagic gastroenteritis and foal necrotizing enteritis. Several investigations have shown that none of the netF -positive C. perfringens isolates examined to date encode the netB gene (Mehdizadeh Gohari et al, 2015 , 2016 , 2017 ). Because of the close homology between NetB and NetE (78% amino acid identity) this is superficially an understandable misinterpretation by Kiu et al but it is incorrect.…”
