Alaria alata – en “ny” parasitær zoonose? – DTU Orbit

In humans, the clinical features of alariosis caused by infections with the North American species of Alaria vary from mild and asymptomatic to moderate with respiratory or cutaneous signs 2 or neuroretinitis 3to severe-to-lethal anaphylactic shock caused by larva migrans 45. Alaria infections can be prevented by keeping canines from scavenging or eating infected prey. Helminth parasites of the wolf Canis lupus from Latvia.

The reparatory nature of the lesions suggests that the inflammation is probably the result of direct tissue damage rather than an immune reaction targeted toward the parasitic antigens.

One of the very first cases reported was a single worm in the eye of a woman from Ontario, Canada. This page was last edited on 22 Marchat The typical structure of muscle fibers was altered around the larvae, with inflammatory cell reactions, represented mainly by lymphocytes, macrophages, and plasma cells Figurepanel D.

Alaria alata in wild boars (Sus scrofa, Linnaeus, 1758) in the eastern parts of Germany

Family suidae Statistical Prevalence. Showing of 9 extracted citations.

Some lesions were found in adult connective tissue, formed by mature collagen scar fibers type I collagen and few inflammatory cells, whereas other lesions had reticulin fibers type III collagen with numerous inflammatory cells.

Alaria alata Anura Sus scrofa. Although data on the pathologic changes caused by Alaria spp. This infection can be treated with alsria. The lack of inflammation was previously observed also with A.

As early asthe German Federal Institute for Risk Assessment pointed out the possible health risk to the consumer posed by this trematode. Lesions produced by mesocercariae of Alaria alata in European mink.

Alaria Schrank Biology of Alaria spp. By microscopy, we observed that morphologic features of these larvae were consistent with A.

Study on the European mink Mustela lutreola helminthocenoses in connection with the American mink M. There have been cases reported of fatal disease with systematic infection with Alaria larvae ingestion of undercooked frog legs. This article has been cited by other articles in PMC. It’s been noted that another possible treatment is with fenbendazole.


Unfortunately for humans, it can be quite harmful and even cause death. The sporocysts then produce cercariae. Humans can be infected by ingesting Alaria larvae, which can be from eating undercooked frog legs or contaminated boar or pig meat.

The mesocercariae transfer to their tissues and remain at this life-cycle stage.

Alaria alata Infection in European Mink

The eggs, which are oval, operculated, and light brown, are released from adult Alaria and excreted from the final host’s faeces and hatched into miracidium that infect the snail alaat, in which the eggs then give rise to the asexual stage known as sporocysts.

In certain histologic sections, the damaged muscular tissue was replaced by granulation tissue in various stages of development Figurepanel F.

The reparatory nature of the lesions suggests that the inflammation is the result of direct tissue damage rather than an immune reaction targeted toward the parasitic antigens. The structure of all mesocercariae observed by microscopy suggested that they were alive and active before the mink carcass was frozen.
