Une nouvelle espèce d’Anisakis chez un phoque méditerranéen

Abstract

Les Nématodes que nous étudions ici proviennent du tube diges tif d'un Phoque, Monachus albiventer, capturé sur la côte orientale de la Sardaigne. La disparition progressive de cet animal en Médi terranée rend particulièrement intéressante l'étude de ses parasites, aussi sommes-nous très reconnaissants au Professeur G. Pegreffi de nous les avoir envoyés pour identification. Malheureusement, ils avaient été auparavant conservés dans le lactophénol qui a dété rioré dans une large mesure la cuticule et détruit plus ou moins complètement les papilles ; nous avons cependant pu mettre en évi dence un certain nombre de caractères qui nous paraissent suffi sants pour l'identification de l'espèce :

How effective is freezing at killing Anisakis simplex, Pseudoterranova krabbei, and P. decipiens larvae? An experimental evaluation of time-temperature conditions

“…Some parasite species may pose a risk to consumers as humans can become accidentally infected with nematodes of the Anisakidae family after consumption of inadequately processed seafood products that contain viable third-stage larvae. Anisakis simplex (Rudolphi 1809) and A. pegreffii (Campana-Rouget and Biocca 1955) have been reported as causative agents of human infection (Ishikura et al 1993; Audicana and Kennedy 2008; Mattiucci et al 2013), but other anisakids (belonging to the Contracaecum (Railliet and Henry 1912) and Pseudoterranova genera (Krabbe 1878)) are also known to represent a hazard to human health (Shamsi and Suthar 2016; Mehrdana et al 2014; Mattiucci et al 2013; Shamsi and Butcher 2011; Torres et al 2007). Symptoms include nausea, diarrhea, vomiting, and intense abdominal pain (Ishikura et al 1993; Hochberg and Hamer 2010).…”

Molecular Diagnosis of Cause of Anisakiasis in Humans, South Korea

“…In the United States, up to 50 human cases are reported each year ( 1 ). Most infections in humans have been caused by Anisakis simplex sensu stricto and Pseudoterranova decipiens nematodes ( 1 ); however, since 1999, a few human infections with Anisakis pegreffii larvae (a sibling species of A. simplex s.s.), originally recovered from a Mediterranean monk seal ( 5 ), have been reported in Italy ( 6 – 9 ) and Japan ( 10 , 11 ). The larvae of A. pegreffii are morphologically distinguished, with difficulty, from those of A. simplex s.s. (both are Anisakis type I); however, molecular techniques can easily distinguish the 2 types of larvae ( 3 , 4 ).…”

<i>Anisakis pegreffii</i> Larvae in Sea Eels (<i>Astroconger myriaster</i>) from the South Sea, Republic of Korea

“…A. pegreffii was first reported from a Mediterranean monk seal in 1955 [ 24 ]. A. pegreffii was subsequently repeatedly reported in marine fish, squids, but rarely humans, in various localities including Europe, Australia, America, and Asia (including Japan, Chia, and Korea) [ 7 , 9 , 25 ].…”
