cantonensis third-stage larvae (L3). L3 larvae are infective to humans, who serve as incidental hosts. They are around 0.5 mm long, possess a pointed terminal projection on the end of the tail, and may be encased in cuticle (exuviae) molted from previous stages.

Which of the following causes a fatal Eosinophilic meningoencephalitis?
Summary: Eosinophilic meningoencephalitis is caused by a variety of helminthic infections. These worm-specific infections are named after the causative worm genera, the most common being angiostrongyliasis, gnathostomiasis, toxocariasis, cysticercosis, schistosomiasis, baylisascariasis, and paragonimiasis.
What parasite causes Eosinophilic meningoencephalitis?
There are three important parasitic infections associated with eosinophilic meningitis: Angiostrongylus cantonensis, Baylisascaris procyonis, and Gnathostoma spinigerum. These are parasites for which humans are incidental hosts.
What causes rat lung disease?
Angiostrongyliasis, also known as rat lungworm, is a disease that affects the brain and spinal cord. It is caused by a parasitic nematode (roundworm parasite) called Angiostrongylus cantonensis. The adult form of A. cantonensis is only found in rodents.
Can humans get lungworm from cats?
The feline lungworm Aelurostrongylus abstrusus cannot be transmitted to humans. Capillaria aerophila, a rarer lungworm, can infect humans but this is very uncommon.
How long does rat lungworm last?
The symptoms usually start 1 to 3 weeks after exposure to the parasite, but have been known to range anywhere from 1 day to as long as 6 weeks after exposure. Although it varies from case to case, the symptoms usually last between 2–8 weeks; symptoms have been reported to last for longer periods of time.
How does a cat get Lungworm?

Is the Angiostrongylus cantonensis male or female?
Figure D: Angiostrongylus adult worm recovered from vitreous humor of a human patient. Males possess a small copulatory bursa (arrow) supported by bursal rays (dart).. The worm is most likely A. cantonensis based on the patient’s geographic location.
Where is the adult form of Angiostrongylus found?
The adult form of the parasite is found only in rodents. Infected rats pass larvae of the parasite in their feces. Snails and slugs get infected by ingesting the larvae. These larvae mature in snails and slugs but do not become adult worms.
How does Angiostrongylus vasorum get into dogs?
Angiostrongylus vasorum is a parasite of foxes and other canids that also finds its way into dogs. Canids acquire infections by the ingestion of gastropod intermediate hosts. Gastropods eat the first-stage larvae while feeding on the feces of infected canids.
Where does a.cantonensis get its parasites from?
The parasite has also been reported from Africa, the Caribbean, Australia, Hawaii, and recently the southern United States. The most notable manifestation of A. cantonensis infection is eosinophilic meningitis caused by the presence of larvae in the brain and resultant local host reactions.
