First report and record of nematode Eustrongylides africanus larvae in a vertebrate host mudfish Clarias species from Bida floodplain of Nigeria
The nematode specimens from Clarias species were confirmed to be the larval forms of nematode Eustrongytides africanus that occurs in a wide diversity of fish-eating aquatic animals. And its effective third- and fourth-stage larval development was also described. The physical presence of this parasite in Clarias species is manifested by swellings or undulations on skin surfaces as grub-like.
