First report of Anisakis simplex (Nematoda, Anisakidae) in the sea lamprey (Petromyzon marinus)

Anisakid nematodes prevalence in Chilean hake (Merluccius gayi gayi) commercialized in the city of Talca, Chile

“…in Brama australis in three southern Chilean localities: 16.8% in Lebu, 10.6% in Calbuco and 6.7% in Punta Arenas (Oliva et al, 2016). Several data demonstrate the importance of this nematode parasite in public health and the risk of infection due to this seafood-borne disease worldwide, which affects many different fish species destined for human consumption such as: Chilean jack mackerel (Trachurus murphyi) (George-Nascimento et al, 1983), sardines (Sardina pilchardus) and anchovies (Engraulis encrasicolus) a b c a d (Serracca et al, 2014;Cavallero et al, 2015;Molina-Fernández et al, 2015), Atlantic mackerel (Scomber scombrus) (Pekmezci, 2014), lamprey (Petromyzon marinus) (Bao et al, 2013), golden kingklip (Genypterus blacodes) and snoek (Thyrsites atun) . Respecting the salmon farmed industry, Marty (2008) described the presence of anisakid larvae in the viscera of a farmed Atlantic salmon (Salmo salar), however, the prevalence described was very low (0.11%) probably because of artificial diets which also contain medications designated for salmon (Sepúlveda et al, 2004).…”

Primer reporte de Anisakis spp. en peces de agua dulce en Huacho, Perú

“…Las larvas Anisakis, especialmente cuando presentan alta intensidad de infección, tienden a ubicarse en partes definidas del pez huésped, principalmente en la cavidad corporal, enquistadas en el hígado, sobre las gónadas, en el mesenterio o adherida a la pared intestinal (Cipriani et al, 2017). Bao et al (2013), evaluando Petromyzon marinus detectaron el 41% de larvas en el músculo, 44% en las gónadas, 4% en el riñón, 1% en hígado y más del 10% diseminado en forma libre. En peces Merluccius merluccius, larvas Anisakis pegreffii estaban distribuidas principalmente en vísceras (62.9%) e hígado (28.3%) (Cipriani et al, 2017), mientras que en peces Clupea harengus L, el 96% de larvas Anisakis simplex estaban distribuidos en la cavidad corporal y el 3.5% se encontraban a ambos lados de la porción ventral de la musculatura que cubre la cavidad visceral (Levsen y Lunestad, 2010).…”

Foodborne anisakiasis and allergy

“…L3-infected crustaceans are then consumed by fish or squid (paratenic hosts), in which, L3s penetrate the intestine and encapsulate in tissues, particularly of the mesentery and liver. Other paratenic hosts, such as lamprey [18], fish and cephalopods [2,19], can also be involved and accumulate L3s in a similar way. Cetaceans then consume L3-infected fish and squid, after which the L3s are released and then develop to fourth-stage larvae (L4s) and subsequently to adult stages (males and females) in the stomach (Figure 1).…”
