Diagnosis Angiostrongylus cantonensis A diagnosis of A. History of ingestion of raw or undercooked intermediate hosts or possibly transport hosts is a crucial clue as well. However, ill persons may not be aware of ingestion of foods that could lead to infection. It is important to note, however, that eosinophilia in the CSF and in the blood may not be present on initial presentation or in late stages of infection. The CSF pressure is generally elevated.

Pathology[ edit ] Pathology is due to both the adults and the eggs. Adults in the ileo-caecal arterioles cause an inflammatory eosinophilic response in humans. In the Cotton Rat the adult worms cause local haemorrhages.
The intestinal wall is also affected. In humans there is a thickening of the intestinal wall ileum, appendix and caecum. In rats with heavy infestations there is a yellow discolouring of the surface of the intestinal walls.
Clinical signs and diagnosis[ edit ] Abdominal pain which presents as a palpable mass on clinical examination Anorexia Diarrhoea Vomiting In the blood and tissue biopsy there is eosinophilia. Other methods of diagnosis from a biopsy are eggs and larvae in the blood vessels.
Imaging of the liver and intestine can also be helpful. Serology is sometimes used to diagnose from a blood sample and there are specific enzyme-linked immunosorbent assays ELISA. This is a rare disease. In Martinique , a French island of the Antilles , two confirmed cases and two probable cases were identified during an year period , with an estimated incidence of 0.
Gule The white-nosed coati Nasua narica is a naturally susceptible definitive host for the zoonotic nematode Angiostrongylus costaricensis in Costa Rica. Cases 3 and 4 illustrate the presumptive and probable diagnoses of less severe forms of HAA, angioztrongylus solely on abdominal symptoms and marked eosinophilia.
