| Summary: | Neðst á síðunni er hægt að nálgast greinina í heild sinni með því að smella á hlekkinn View/Open Recently, two human cases of Pseudoterranova decipiens nematode larvae were confirmed in Iceland. In each case a larva was found in the throat five and six days after the consumption of insufficiently cooked filets of the common catfish Anarhicas lupus that were bought fresh in a fish store. In both cases the larva had already developed from 3rd to the 4th stage during the time of infection. In the former case a young male woke up in the morning as he noticed a larva crawling around in his throat. In the latter case a young woman coughed up the larva after intense itching in her throat. Anisakid larva of Pseudoterranova decipiens and Anisakis simplex are common in fish around Iceland. Both are known as human pathogens but usually Anisakis simplex causes more severe symptoms and is more commonly found in human cases than Pseudoterranova decipiens. Traditional cooking of fish in Iceland by boiling or thorough frying before consumption is believed to prevent human anisakidosis in Iceland. However, increased consumption of fresh or poorly heated fish and fish products might result in increased anisakidosis cases in Iceland. Greint er frá tveimur tilfellum hringormasmits í fólki hér á landi. Tegundin Pseudoterranova decipiens fannst í koki tveggja einstaklinga sem neytt höfðu illa hitaðra rétta úr ferskum steinbít fimm og sex dögum áður. Þriðja stigs lirfur upprunnar úr fiskholdinu höfðu í báðum tilvikum þroskast upp á 4. stig á þeim tíma sem liðinn var frá smitun. Í fyrra tilvikinu vaknaði ungur karlmaður við að ormur var að hreyfa sig í koki og í hinu fann ung kona fyrir ertingu í hálsi. Þegar hún hóstaði barst lirfan upp í kok. Lirfur hringormanna Pseudoterranova decipiens og Anisakis simplex eru algengar í fiskum við Íslandsstrendur. Menn eru ekki náttúrulegir lokahýslar en hringormar sem koma úr fiski geta lifað í fólki og valdið sjúkdómi. Erlendis er Anisakis simplex mun algengari sjúkdómsvaldur og oftast heldur ... |
