Nematode parasites of the Anisakides family are often found in people living in countries where fish is consumed raw or partially cooked. This research shows the histological changes in the liver and spleen of Mugil incilis, collected in Cartagena Bay. These changes are associated with pollution by organochlorine pesticides and their possible influence on the parasite. Organochlorine compounds were extracted using the headspace-solid-phase microextraction (HS-SPME) technique. Residual amounts in the muscle of M. incilis such as β-HCH, γ-HCH, heptachlor, aldrin, endosulfan, 4,4'-DDE, and dieldrin, among others, were identified by gas chromatography connected to an electron capture detector, indicating that the fauna of Cartagena Bay are exposed to these pollutants. Histological analysis was carried out on liver and spleen samples of M. incilis which were fixed, processed, and embedded in paraffin. The presence of melano-macrophages, granulomes, and trematodes in the liver was the most important changes observed. Larval prevalence for the Anisakis spp. was determined to be 1.6%; for Pseudoterranova spp., 25.3%, and for Contracaecum spp., 57.8%. Other parasites such as acanthocephalans were also reported for a total of 15.3%. Nevertheless, no significant correlation between parasites and organochlorines was found. This study is the first to correlate the presence of organochlorine compounds and histological damage in the liver and spleen of M. incilis, with the presence of parasites in fish from Cartagena Bay (Colombia).

“…Although larval stages are found commonly in species of teleosts, frequently in species used for human consumption, identification beyond the level of genus is virtually impossible using morphological methods, resulting in the larvae being assigned to various morphotypes designated by Roman numerals (Cannon 1977a(Cannon , 1977bCannon 1989, 1990;Bruce 1990aBruce , 1990bNash 1998;Lymbery et al 2002;Doupé et al 2003;Muñoz et al 2007;Shamsi 2007;Shamsi et al 2008Shamsi et al , 2011aShamsi et al , 2011bShamsi et al , 2012Jabbar et al 2012aJabbar et al , 2012b. The more recent introduction of molecular techniques has allowed the identification of some larval stages in teleosts and, as a consequence, the identification of life-cycle patterns Nascetti 2006, 2008).…”

A survey was undertaken to characterise larval anisakid nematodes present in teleosts at Lizard Island on the northern Great Barrier Reef. In total, 464 fish were examined from 32 families, 62 genera and 107 species. Anisakid nematodes were found in 46 (9.9%) of the fish examined. Infections in Atherinidae, Lethrinidae, Lutjanidae and Serranidae were moderately prevalent, with the intensities of infection ranging from 1 to 80; whereas in the Sphyraenidae and Scombridae, the prevalence of infection was very high, with intensities ranging from 1 to .375 anisakids. A combined morphological and molecular-phylogenetic approach was employed to identify larval anisakid nematodes to species and/ or genotypes. The nematodes examined were identified as Anisakis typica (three genotypes based on molecular characterisation), Terranova Types I (five genotypes) and II (five genotypes) and Hysterothylacium Types IV, V (four genotypes), VI and X. The findings of the present study provide some insights into the distribution of larval anisakid nematodes in coral-reef fishes and a basis for future investigations of anisakid populations in marine fishes.Additional keywords: Anisakidae, first and second internal transcribed spacers (ITS-1 and ITS-2) of nuclear ribosomal DNA, Nematoda, single-strand conformation polymorphism (SSCP) analysis.
