Acute intestinal anisakiasis in Spain: a fourth-stage Anisakis simplex larva. (1/62)
A case of acute intestinal anisakiasis has been reported; a nematode larva being found in the submucosa of the ileum of a woman in Jaen (Spain). The source of infection was the ingestion of raw Engraulis encrasicholus. On the basis of its morphology, the worm has been identified as a fourth-stage larva of Anisakis simplex. In Spain, this is the ninth report of human anisakiasis and also probably the first case of anisakiasis caused by a fourth-stage larva of A. simplex. (+info)Purification and cloning of an apoptosis-inducing protein derived from fish infected with Anisakis simplex, a causative nematode of human anisakiasis. (2/62)
While investigating the effect of marine products on cell growth, we found that visceral extracts of Chub mackerel, an ocean fish, had a powerful and dose-dependent apoptosis-inducing effect on a variety of mammalian tumor cells. This activity was strikingly dependent on infection of the C. mackerel with the larval nematode, Anisakis simplex. After purification of the protein responsible for the apoptosis-inducing activity, we cloned the corresponding gene and found it to be a flavoprotein. This protein, termed apoptosis-inducing protein (AIP), was also found to possess an endoplasmic reticulum retention signal (C-terminal KDEL sequence) and H2O2-producing activity, indicating that we had isolated a novel reticuloplasimin with potent apoptosis-inducing activity. AIP was induced in fish only after infection with larval nematode and was localized to capsules that formed around larvae to prevent their migration to host tissues. Our results suggest that AIP may function to impede nematode infection. (+info)Apoptosis-inducing protein, AIP, from parasite-infected fish induces apoptosis in mammalian cells by two different molecular mechanisms. (3/62)
AIP (apoptosis-inducing protein) is a protein purified and cloned from Chub mackerel infected with the larval nematode, Anisakis simplex, which induces apoptosis in various mammalian cells including human tumor cell lines. AIP has shown structural and functional homology to L-amino acid oxidase (LAO) which oxidizes several L-amino acids including L-lysine and AIP-induced apoptosis has been suggested to be mediated by H2O2 generated by LAO activity of AIP. In this study, we confirmed that recombinant AIP generated enough H2O2 in culture medium to induce rapid apoptosis in cells and this apoptosis was clearly inhibited by co-cultivation with antioxidants such as catalase and N-acetyl-cysteine. Surprisingly, however, we found that AIP still could induce H2O2-independent apoptosis more slowly than H2O2-dependent one in HL-60 cells even in the presence of antioxidants. In addition, the HL-60-derived cell line HP100-1, which is a H2O2-resistant variant, underwent apoptosis on treatment with AIP with a similar delayed time course. The latter apoptosis was completely blocked by addition of L-lysine to the culture medium, which is the best substrate of AIP as LAO, indicating that decreased concentration of L-lysine in the culture medium by AIP-treatment induced apoptosis. We also showed that the both apoptosis by AIP were associated with the release of cytochrome c from mitochondria and activation of caspase-9, and overexpressed Bcl-2 could inhibit both of the AIP-induced apoptosis. These results indicate that AIP induces apoptosis in cells by two distinct mechanisms; one rapid and mediated by H2O2, the other delayed and mediated by deprivation of L-lysine, both of which utilize caspase-9/cytochrome c system. (+info)Ascaris suum-derived products induce human neutrophil activation via a G protein-coupled receptor that interacts with the interleukin-8 receptor pathway. (4/62)
Infection with tissue-migrating helminths is frequently associated with intense granulocyte infiltrations. Several host-derived factors are known to mediate granulocyte recruitment to the tissues, but less attention has been paid to how parasite-derived products trigger this process. Parasite-derived chemotactic factors which selectively recruit granulocytes have been described, but nothing is known about which cellular receptors respond to these agents. The effect of products from the nematodes Ascaris suum, Toxocara canis, and Anisakis simplex on human neutrophils were studied. We monitored four parameters of activation: chemotaxis, cell polarization, intracellular Ca(2+) transients, and priming of superoxide anion production. Body fluids of A. suum (ABF) and T. canis (TcBF) induced strong directional migration, shape change, and intracellular Ca(2+) transients. ABF also primed neutrophils for production of superoxide anions. Calcium mobilization in response to A. suum-derived products was completely abrogated by pretreatment with pertussis toxin, implicating a classical G protein-coupled receptor mechanism in the response to ABF. Moreover, pretreatment with interleukin-8 (IL-8) completely abrogated the response to ABF, demonstrating desensitization of a common pathway. However, ABF was unable to fully desensitize the response to IL-8, and binding to CXCR1 or CXCR2 was excluded in experiments using RBL-2H3 cells transfected with the two human IL-8 receptors. Our results provide the first evidence for a direct interaction between a parasite-derived chemotactic factor and the host's chemotactic network, via a novel G protein-coupled receptor which interacts with the IL-8 receptor pathway. (+info)Fitness of the marine parasitic nematode Anisakis simplex s. str. in temperate waters of the NE Atlantic. (5/62)
In temperate waters of the NE Atlantic, third-stage larvae of Anisakis simplex sensu stricto collected from 3 paratenic host species were identified by restriction fragment length polymorphisms. The condition of wild larval infrapopulations was assessed by examining morphometric and growth characteristics. The differentiation patterns and the excretory/secretory products of larvae grown in vitro were also examined. An extensive morphometric, growth and differentiation variability was found between parasite larvae collected from different paratenic host sources. Nematode infrapopulation larvae from the squid comprise those smaller individuals with the lowest values of survival rates and moult success. It may be then concluded that the fitness of A. simplex s. str. larvae is not the best possible in the squid, which impaired the competitiveness of the parasite and its chances of developing into an adult. This suggests that the microenvironments impaired by the paratenic host may provide larval infrapopulations with unique ecological factors probably influencing its recruitment to the final host populations. (+info)Interleukin-4 production in BALB/c mice immunized with Anisakis simplex. (6/62)
We investigated the interleukin (IL-4) levels in BALB/c mice immunized with Anisakis extract in single or multiple doses and in mice orally infected with a larva. From animals immunized maximum responses were obtained with the multiple doses with an only IL-4 peak. Conversely, in the mice inoculated with a larva per os, the IL-4 levels showed two peaks of different rates. (+info)Evaluation by ELISA of anisakis simplex larval antigen purified by affinity chromatography. (7/62)
In order to improve the specificity and sensitivity of the techniques for the human anisakidosis diagnosis, a method of affinity chromatography for the purification of species-specific antigens from Anisakis simplex third-stage larvae (L3) has been developed. New Zealand rabbits were immunized with A. simplex or Ascaris suum antigens or inoculated with Toxocara canis embryonated eggs. The IgG specific antibodies were isolated by means of protein A-Sepharose CL-4B beads columns. IgG anti-A. simplex and -A. suum were coupled to CNBr-activated Sepharose 4B. For the purification of the larval A. simplex antigens, these were loaded into the anti-A. simplex column and bound antigens eluted. For the elimination of the epitopes responsible for the cross-reactions, the A. simplex specific proteins were loaded into the anti-A. suum column. To prove the specificity of the isolated proteins, immunochemical analyses by polyacrylamide gel electrophoresis were carried out. Further, we studied the different responses by ELISA to the different antigenic preparations of A. simplex used, observing their capability of discriminating among the different antisera raised in rabbits (anti-A. simplex, anti-A. suum, anti-T. canis). The discriminatory capability with the anti-T. canis antisera was good using the larval A. simplex crude extract (CE) antigen. When larval A. simplex CE antigen was loaded into a CNBr-activated Sepharose 4B coupled to IgG from rabbits immunized with A. simplex CE antigen, its capability for discriminate between A. simplex and A. suum was improved, increasing in the case of T. canis. The best results were obtained using larval A. simplex CE antigen loaded into a CNBr-activated Sepharose 4B coupled to IgG from rabbits immunized with adult A. suum CE antigen. When we compared the different serum dilution and antigenic concentration, we selected the working serum dilution of (1/4)00 and 1 microg/ml of antigenic concentration. (+info)A case of acute gastric anisakiasis provoking severe clinical problems by multiple infection. (8/62)
Acute gastric anisakiasis with multiple anisakid larvae infection is reported. A 68-year-old woman residing in Busan, Korea, had epigastric pain with severe vomiting about 5 hours after eating raw anchovies. Four nematode larvae penetrating the gastric mucosae in the great curvature of the middle body and fundus were found and removed during gastro-endoscopic examination. Another one thread-like moving larva was found in the great curvature of upper body on the following day. On the basis of their morphology, the worms were identified as the 3rd stage larvae of Anisakis simplex. This case is acute gastric anisakiasis provoking severe clinical problems by the multiple infection and the greatest number of anisakid larvae found in a patient in Korea. (+info)Anisakis is a genus of parasitic nematode (roundworm) that can infect marine mammals, fish, and squid. Humans can become accidentally infected when they consume raw or undercooked seafood that contains Anisakis larvae. This type of infection is known as "anisakiasis" or "herring worm disease."
The infection can cause gastrointestinal symptoms such as abdominal pain, nausea, vomiting, and diarrhea. In some cases, the larvae may penetrate the wall of the gastrointestinal tract, leading to more severe symptoms such as allergic reactions, eosinophilic granulomas, or intestinal obstruction.
Preventing anisakiasis involves cooking or freezing fish and seafood thoroughly before consumption. Freezing fish at -20°C (-4°F) for at least 7 days can kill the larvae, making it safe to eat raw. Proper handling and storage of seafood can also help reduce the risk of infection.
Anisakiasis is a gastrointestinal disease caused by the accidental consumption and infection with larvae of nematode parasites belonging to the genus Anisakis. The life cycle of these parasites typically involves marine animals such as fish and squid, which serve as intermediate or paratenic hosts. Human infections usually occur when people eat raw or undercooked seafood that contains infective larvae.
After ingestion, the larvae can penetrate the gastrointestinal mucosa, causing an inflammatory reaction and potentially leading to symptoms such as abdominal pain, nausea, vomiting, diarrhea, or fever. In some cases, the larvae may invade deeper tissues, resulting in more severe complications like allergic reactions, intestinal obstruction, or perforation.
Diagnosis of anisakiasis is often based on clinical presentation, epidemiological data, and detection of parasite larvae in biopsy samples, stool specimens, or vomitus. Treatment typically involves endoscopic removal of the larvae, supportive care for symptoms, and sometimes anti-parasitic medication. Preventive measures include thoroughly cooking seafood, freezing it at temperatures below -20°C (-4°F) for at least 7 days, or practicing proper hygiene during food preparation to minimize the risk of infection.
Antibodies are proteins produced by the immune system in response to the presence of a foreign substance, known as an antigen. They are capable of recognizing and binding to specific antigens, neutralizing or marking them for destruction by other immune cells.
Helminths are parasitic worms that can infect humans and animals. They include roundworms, tapeworms, and flukes, among others. Helminth infections can cause a range of symptoms, depending on the type of worm and the location of the infection.
Antibodies to helminths are produced by the immune system in response to an infection with one of these parasitic worms. These antibodies can be detected in the blood and serve as evidence of a current or past infection. They may also play a role in protecting against future infections with the same type of worm.
There are several different classes of antibodies, including IgA, IgD, IgE, IgG, and IgM. Antibodies to helminths are typically of the IgE class, which are associated with allergic reactions and the defense against parasites. IgE antibodies can bind to mast cells and basophils, triggering the release of histamine and other inflammatory mediators that help to protect against the worm.
In addition to IgE, other classes of antibodies may also be produced in response to a helminth infection. For example, IgG antibodies may be produced later in the course of the infection and can provide long-term immunity to reinfection. IgA antibodies may also be produced and can help to prevent the attachment and entry of the worm into the body.
Overall, the production of antibodies to helminths is an important part of the immune response to these parasitic worms. However, in some cases, the presence of these antibodies may also be associated with allergic reactions or other immunological disorders.
Helminth antigens refer to the proteins or other molecules found on the surface or within helminth parasites that can stimulate an immune response in a host organism. Helminths are large, multicellular parasitic worms that can infect various tissues and organs in humans and animals, causing diseases such as schistosomiasis, lymphatic filariasis, and soil-transmitted helminthiases.
Helminth antigens can be recognized by the host's immune system as foreign invaders, leading to the activation of various immune cells and the production of antibodies. However, many helminths have evolved mechanisms to evade or suppress the host's immune response, allowing them to establish long-term infections.
Studying helminth antigens is important for understanding the immunology of helminth infections and developing new strategies for diagnosis, treatment, and prevention. Some researchers have also explored the potential therapeutic use of helminth antigens or whole helminths as a way to modulate the immune system and treat autoimmune diseases or allergies. However, more research is needed to determine the safety and efficacy of these approaches.
Food parasitology is not a commonly used term in medical or scientific communities. However, it generally refers to the study of parasites that are transmitted through food, including parasitic protozoa, helminths (worms), and arthropods (e.g., tapeworms, roundworms, Giardia, Cryptosporidium, etc.). Food parasitology involves understanding the life cycles, epidemiology, diagnosis, treatment, and prevention of these foodborne parasites. It is an important field within medical and veterinary parasitology, as well as food safety and public health.
Nematode infections, also known as roundworm infections, are caused by various species of nematodes or roundworms. These parasitic worms can infect humans and animals, leading to a range of health problems depending on the specific type of nematode and the location of the infection within the body.
Common forms of nematode infections include:
1. Ascariasis: Caused by Ascaris lumbricoides, this infection occurs when people ingest the parasite's eggs through contaminated food or water. The larvae hatch in the small intestine, mature into adult worms, and can cause abdominal pain, nausea, vomiting, and diarrhea. In severe cases, the worms may obstruct the intestines or migrate to other organs, leading to potentially life-threatening complications.
2. Hookworm infections: These are caused by Ancylostoma duodenale and Necator americanus. The larvae penetrate the skin, usually through bare feet, and migrate to the small intestine, where they attach to the intestinal wall and feed on blood. Symptoms include abdominal pain, diarrhea, anemia, and protein loss.
3. Trichuriasis: Also known as whipworm infection, this is caused by Trichuris trichiura. The larvae hatch in the small intestine, mature into adult worms, and reside in the large intestine, causing abdominal pain, diarrhea, and rectal prolapse in severe cases.
4. Strongyloidiasis: Caused by Strongyloides stercoralis, this infection occurs when the larvae penetrate the skin, usually through contaminated soil, and migrate to the lungs and then the small intestine. Symptoms include abdominal pain, diarrhea, and skin rashes. In immunocompromised individuals, strongyloidiasis can lead to disseminated disease, which is potentially fatal.
5. Toxocariasis: This infection is caused by the roundworms Toxocara canis or Toxocara cati, found in dogs and cats, respectively. Humans become infected through ingestion of contaminated soil or undercooked meat. Symptoms include fever, cough, abdominal pain, and vision loss in severe cases.
6. Enterobiasis: Also known as pinworm infection, this is caused by Enterobius vermicularis. The larvae hatch in the small intestine, mature into adult worms, and reside in the large intestine, causing perianal itching and restlessness, especially at night.
Preventive measures include:
1. Proper hand hygiene: Wash hands with soap and water after using the toilet, changing diapers, handling pets or their feces, and before preparing or eating food.
2. Personal hygiene: Keep fingernails short and clean, avoid biting nails, and wear shoes in public areas, especially where soil may be contaminated with human or animal feces.
3. Food safety: Wash fruits and vegetables thoroughly, cook meat properly, and avoid consuming raw or undercooked meat, poultry, or fish.
4. Environmental cleanliness: Regularly clean surfaces that come into contact with food, such as countertops, cutting boards, and utensils. Dispose of trash properly and maintain a clean living environment.
5. Pet care: Keep pets healthy and regularly deworm them as recommended by a veterinarian. Pick up pet feces promptly to prevent contamination of the environment.
6. Public health measures: Implement public health interventions, such as regular waste disposal, sewage treatment, and vector control, to reduce the transmission of parasitic infections.
"Oncorhynchus" is a genus of fish that includes several species of salmon and trout. These are primarily freshwater fish that are native to the northern Pacific Ocean and its surrounding rivers and streams, but some species have been introduced widely throughout the world. They are known for their distinctive life cycle, which involves migrating from fresh water to the ocean and then returning to fresh water to spawn. Many Oncorhynchus species are highly valued as food fish and are also popular game fish.
Urticaria, also known as hives, is an allergic reaction that appears on the skin. It is characterized by the rapid appearance of swollen, pale red bumps or plaques (wheals) on the skin, which are often accompanied by itching, stinging, or burning sensations. These wheals can vary in size and shape, and they may change location and appear in different places over a period of hours or days. Urticaria is usually caused by an allergic reaction to food, medication, or other substances, but it can also be triggered by physical factors such as heat, cold, pressure, or exercise. The condition is generally harmless, but severe cases of urticaria may indicate a more serious underlying medical issue and should be evaluated by a healthcare professional.

- The musculature of 811 Atlantic cod (Gadus morhua) from five cod stocks in the Northwest Atlantic off Newfoundland and Labrador, and on the Flemish Cap, were examined for two ascaridoid nematodes, Anisakis simplex sensu lato and Pseudoterranova decipiens sensu lato. (mun.ca)
Larva1
- Two of these cases are presented, in one of which an intact Anisakis -like larva was found in an eosinophilic phlegmon of the intestine after surgical excision because of abdominal symptoms. (ajtmh.org)
Parasite3
- People who produce immunoglobulin E in response to this parasite may subsequently have an allergic reaction, including anaphylaxis, after eating fish infected with Anisakis species. (wikipedia.org)
- Anisakis is a parasite that resides in the GI tract of marine mammals. (msdmanuals.com)
- These high parasite population densities within an individual fish host offer a chance to explore new sources of variations for the genetic structure of Anisakis spp. (bvsalud.org)
Seafood2
Sardines1
- The results of this survey showed a very low Anisakis risk in anchovies caught off north-western Adriatic coast and in sardines from all the fishing areas under study. (unibo.it)

18601
- Genetic variation at 21 gene-enzyme systems was studied in a sample of an adult population of Anisakis typica (Diesing, 1860) recovered in the dolphin Sotalia fluviatilis from the Atlantic coast of Brazil. (scite.ai)
Humans3
- As the gut of a marine mammal is functionally very similar to that of a human, Anisakis species are able to infect humans who eat raw or undercooked fish. (wikipedia.org)
- Unlike anisakis, tapeworms don't always manifest themselves with clear symptoms and can live in humans for decades if untreated, resulting in weight loss, Vitamin B12 deficiency, and potential anemia. (beyondsalmon.com)
- They can't reproduce until they find a mammal host (in the case of anisakis and cod worm, it has to be a marine mammal like a seal, so they can't reproduce in a human), and tapeworms rarely make it into humans. (beyondsalmon.com)
Typica1
- Characteristic allozymes are given for the identification, at any life-stage and in both sexes, of A. typica and the other Anisakis species so far studied genetically. (scite.ai)
Sensitization1
- Sensitization to Anisakis was confirmed by detecting serum specific IgE to Anisakis simplex. (nih.gov)

Infects1
- In the stage which infects fish, Anisakis species are found in a distinctive "watch-spring coil" shape. (wikipedia.org)
Tapeworm2
- Surviving the human intestinal track isn't easy and requires that anisakis and tapeworm be at full strength. (beyondsalmon.com)
- They are fascinating organisms and you can read all about the anisakis life cycle and the tapeworm life cycle on wikipedia. (beyondsalmon.com)

Genetically1
- Each final host species was discovered to have its own biochemically and genetically identifiable "sibling species" of Anisakis, which is reproductively isolated. (wikipedia.org)
Tuna1
- However, anisakis is rare in other salt water fish, such as tuna, swordfish and farm-raised salmon. (beyondsalmon.com)
Clinical1
- The clinical manifestations depend on the effect of Anisakis simplex on the digestive tract wall. (medscape.com)
Frozen1
- Freezing for at least 24h at -20° C (until the center of the meat is frozen) will kill Anisakis. (microbe.tv)
Citation1
- citation needed] Anisakis species have complex life cycles which pass through a number of hosts through the course of their lives. (wikipedia.org)
Salmon1
- Anisakis simplex is most common in fresh water and anadromous fish, like wild salmon, which are born in fresh water, migrate to the ocean, then return to fresh water to reproduce. (beyondsalmon.com)
