Corrigendum.

The following errors were identified in the published article by Khamesipour et al., (2021):

On page 26, left column, second paragraph, lines 16–19 read:

“Helminths commonly infecting equines include Trichostrongylus sp., Paramphistommatidae, Fasciola sp., Strongylus sp., Dicrocoelium sp., Moniezia sp., Trichuris sp., Oxyuris sp., Parascaris sp., Prostmayaria sp., Strongyloides sp. and the Cyathostomins (Hosseini et al., 2009)”.

This should be:

“Helminths that have been reported to infect equines include Trichostrongylus sp., Fasciola sp., Strongylus sp., Dicrocoelium sp., Oxyuris sp., Parascaris sp., Prostmayaria sp., Strongyloides sp., and the Cyathostomins (Hosseini et al., 2009)”.

On page 27, right column, line 1 of the Results section reads:

“The results revealed publications from 2005 to 2017.”

This should be:

“The results revealed publications from 1995 to 2017.”

On pages 28 and 29, Table 1 included some incorrect information. The correct table appears on the next pages.
