“…There have been no studies investigating the possibility of diversity within the species, subspecies, or strains of the above-mentioned parasites in the diseases they elicit, which will be further complicated by the high degree of polymorphism of immune genes in humans. However, some authors have suggested that P. decipiens larvae, especially those found in the United States, are less invasive and less pathogenic than are A. simplex larvae (79,174,205).…”

“…Development of better diagnostic tools and greater awareness has resulted in an increase in the frequency of reports in many parts of the world, including the United States (77,79,205) since the 1980s and Canada (63) and Europe (40,69,208,219,249) since the 1990s. Sakanari and McKerrow (233) pointed out reasons for the increased number of cases in the United States in the 1980s that are still applicable worldwide today, summarized as follows: (i) the well-known worldwide distribution of anisakid nematodes (reviewed in references 251 and 281), which have been reported from all major oceans and seas; (ii) the increase in marine mammal populations (hosts of the adult parasites) as a result of conservation measures; (iii) human migratory movements and globalization and the consequent increase in consumer interest in exotic dishes; (iv) the use of faster cooking tools (microwave cookers, etc.)…”

Anisakis simplex: from Obscure Infectious Worm to Inducer of Immune Hypersensitivity

SUMMARY Infection of humans with the nematode worm parasite Anisakis simplex was first described in the 1960s in association with the consumption of raw or undercooked fish. During the 1990s it was realized that even the ingestion of dead worms in food fish can cause severe hypersensitivity reactions, that these may be more prevalent than infection itself, and that this outcome could be associated with food preparations previously considered safe. Not only may allergic symptoms arise from infection by the parasites (“gastroallergic anisakiasis”), but true anaphylactic reactions can also occur following exposure to allergens from dead worms by food-borne, airborne, or skin contact routes. This review discusses A. simplex pathogenesis in humans, covering immune hypersensitivity reactions both in the context of a living infection and in terms of exposure to its allergens by other routes. Over the last 20 years, several studies have concentrated on A. simplex antigen characterization and innate as well as adaptive immune response to this parasite. Molecular characterization of Anisakis allergens and isolation of their encoding cDNAs is now an active field of research that should provide improved diagnostic tools in addition to tools with which to enhance our understanding of pathogenesis and controversial aspects of A. simplex allergy. We also discuss the potential relevance of parasite products such as allergens, proteinases, and proteinase inhibitors and the activation of basophils, eosinophils, and mast cells in the induction of A. simplex-related immune hypersensitivity states induced by exposure to the parasite, dead or alive.

“…data) have resulted in massive losses in farmed cichlid fish (Paperna 1995). Because the adult stages of many heterophyids are nonfastidious in their choice of definite hosts, infections with severe clinical consequences have been reported in humans after consuming fish infected with metacercariae (Deardorff & Overstreet 1990, Ko 1995. Witenberg (1929) described 14 species of the Family Heterophyidae from both naturally and experimentally infected avian and mammalian definitive hosts.…”

Infections by trematodes are among the most common fish-borne zoonoses. Metacercariae of the Family Heterophyidae in marine and freshwater fishes are nonfastidious in their choice of definitive hosts, and therefore, cause infections in human and domestic animals. In the present study, species-specific polymerase chain reaction (PCR) assays were developed for identifying and differentiating the various species examined. Sequencing and aligning the 18S (SSU) rDNA revealed interspecific variation for which species-specific DNA oligonucleotides were designed and used for the identification of 6 heterophyid species recovered from piscivorous birds. The oligonucleotides were further used to evaluate the various stages (cercariae recovered from snails, metacercariae recovered from fish and adult trematodes) of the digeneans. By applying this method we elucidated for the first time the life cycle of Pygidiopsis genata. The phylogenetic interrelationship among the newly sequenced species of Heterophyidae is outlined.KEY WORDS: Digenea · Heterophyidae · Birds · Fish · 18S rDNA gene · SSU Resale or republication not permitted without written consent of the publisherDis Aquat Org 59: [35][36][37][38][39][40][41] 2004 were then used for identification of cercariae recovered from snails and metacercariae recovered from fish, demonstrating their usefulness as a diagnostic tool important for fish and public health. An effort made to define the entire life history of Pygidiopsis genata was successfully carried out. Finally we attempted to examine the phylogenetic links between the Heterophyidae and various other trematodes that were concurrently investigated. MATERIALS AND METHODSSources of parasites and morphological characterization. During 2000 to 2002, adult trematodes were collected from 45 cormorants Phalacrocorax carbo, 4 little egrets Egretta garzetta, 3 night herons Nycticorax nycticorax, 2 white pelicans Pelecanus onocrotalus and a catfish Clarias gariepinus. Collection permits were obtained from the Office of Nature Conservation, Ministry of Environmental Quality, Israel.Trematodes were collected from the sedimentation of the intestine content, then removed and placed in clean physiological saline and preserved in 70% ethanol. Several specimens of each species were fixed in 70% ethanol overnight under light pressure, stained with Aceto-Carmine, and whole mounted for morphologic examination.Metacercariae of Centrocestus sp. (gills), Haplorchis sp. (subcutaneous) Phagicola sp. (heart: conus arteriosus) and Pygidiopsis sp. (kidney), and an unidentified metacercaria from the liver, were obtained from Tilapia zillii (Cichlidae). The fish were collected from commercial fish ponds and Lake Kinneret. Clinostomum complanatum metacercariae (subcutaneous, intermuscular) were collected from Barbus canis (Cyprinidae) from Lake Kinneret. All metacercariae were preserved in 70% ethanol.Cercariae were collected from 3 species of freshwater snails (Melanoides tuberculata, Melanopsis costata and Bythinia hawaderiana) from ...

“…Gastrointestinal illnesses have been epidemiologically linked to scuba diving in sewage-contaminated waters (MMWR 1983). Anasikiasis is a rare nematode (roundworm) infection acquired through consumption of raw fish and cephalopods (Deardoff and Overstreet 1991); a similar disease associated with the helminthes Gnathostoma has been reported in Southeast Asia and the Middle East (Anantaphruti 2001). Diphyllobothriasis, or fish tapeworm disease, was traditionally associated with gefilte fish preparation by Jewish women; approximately 10% of people in Scandinavia are reportedly infected with Diphyllobothrium (Fleming et al 2000).…”

We need to critically assess the present quality of the marine ecosystem, especially the connection between ecosystem change and threats to human health. In this article we review the current state of indicators to link changes in marine organisms with eventual effects to human health, identify research opportunities in the use of indicators of ocean and human health, and discuss how to establish collaborations between national and international governmental and private sector groups. We present a synthesis of the present state of understanding of the connection between ocean health and human health, a discussion of areas where resources are required, and a discussion of critical research needs and a template for future work in this field. To understand fully the interactions between ocean health and human health, programs should be organized around a "models-based" approach focusing on critical themes and attributes of marine environmental and public health risks. Given the extent and complex nature of ocean and human health issues, a program networking across geographic and disciplinary boundaries is essential. The overall goal of this approach would be the early detection of potential marine-based contaminants, the protection of marine ecosystems, the prevention of associated human illness, and by implication, the development of products to enhance human well-being. The tight connection between research and monitoring is essential to develop such an indicator-based effort.
