Marmara denizi Atlantik uskumrularındaki (Scomber scombrus, Linnaeus 1758) Anisakis spp. enfeksiyonu

Abstract

This study was aimed to determine the parasite infection of fish samples. Ten Atlantic mackerel (Scomber scombrus), which were suspected with parasite infection, were sent from the fisherman at the Sea of Marmara, Turkey. The skin, fins, eyes, buccal cavity, and gills were examined regarding ectoparasites, while internal organs were investigated concerning endoparasites. Seven of 10 fish were infected with endoparasites. A total of 27 nematode larvae were detected from the abdominal cavity of fish. The detected nematode larvae were rinsed in 0.9 % isotonic saline and preserved in glycerine-alcohol until used. After that anterior and posterior end of samples were cleared in lactophenol. The larvae had a prominent boring tooth at the anterior end. The body features of the larvae were measured (body width, oesophagus length, ventriculus length and mucron length) on a light microscope (10x-40x). Morphological analysis showed that all samples were identified as Anisakis Type I larvae (L3). It is known that anisakiasis is one of the important fish-borne zoonotic diseases. Also, this nematode species had been previously reported in Turkish water from different fish species. The present case contributes valuable information about one of the intermediate hosts of Anisakis spp. in Turkey.
