New host record of Dujardinascaris sphyraenaii (Bilqees et al., 1977). (Nematode: Heterocheilidae) parasitism in the Psettodes erumei fish, with note on the pathology of infection North West of Arabian gulf, Iraq

Abstract

New host and geographic distribution of Dujardinascaris sphyraenaii is recorded as nematode parasite in the Psettodes erumei fishes in Arabian gulf, The histopathological lesions were manifested as chronic gastroenteritis with diffuse and granulomatous lesions in the liver, The infected liver grossly appeared abnormal due to its darker color and slightly swelling of the site of attachment of the worm hepatopancreatic necrosis and fatty degeneration. Pathological lesions of nematode parasitic manifestation of infected are observed, Most of tissue were abnormal with the erosion and necrosis in some region. Fishes were collected from Arabian Gulf. 61 samples were examined for parasites during the year 2015; the infection rate was 100% during all seasons of the year. The parasitic infestations were identified morphologically as Nematode, Genus: Dujardinascaris sphyraenaii Baylis, 1947Anisakis simplex third stage larva.
