Ability of Anisakis Infestation in Dogs Compared in Haematological Changes

Abstract

The third-stage (L3) larvae of Anisakis are the causative agents of human Anisakiasis caused by the consumption of raw or undercooked seafood infected with anisakid nematodes. If the larvae are not removed, infection with these worms can result in severe eosinophilic infiltration and the development of granulomas in the gastrointestinal system, and stomach pain, nausea, and diarrhea. In the present study, thirty specimens of the European hake (Merluccius merluccius) were collected from Tripoli port, the Libyan coast. Fish were necropsied and dissected to investigate the presence of Anisakis spp. Fresh larvae were inoculated into dogs orally. A hematological examination and postmortem of the stomach and intestines have demonstrated the effect of fresh larvae in dogs. The results indicated that The parasite could implant in the stomach layers 12 hours after ingestion, penetrate 48 hours later, and penetrate the intestine 96 hours after ingestion. The parasite also has the ability to change the blood film, as the rise was noticeable, respectively, in white blood cells, especially Eosinophils and Basophils. It is becoming increasingly likely to influence Anisakis spp. Human health has been underestimated, and perhaps it is time to consider more comprehensive measures than those currently applied to protect public health.
