RESUMO
Cerebral angiostrongyliasis due to Angiostrongylus cantonensis continues to affect human health and productivity in Thailand. The dietary habits of the populace have been an important contributing factor, particularly in the northeast of the country where the disease is endemic and the indigenous people enjoy a local undercooked snail dish called "koi-hoi". Hundreds of cases of disease continue to be reported annually. Because of the difficulty in obtaining a definitive diagnosis, immunological methods have played an important role in the confirmation of A. cantonensis infection. Although enzyme-linked immunosorbent assay (ELISA) and immunoblot are test formats that have been used over the past decade, modern molecular approaches, such as PCR-based diagnostic techniques, are being developed and assessed as additional tests for the diagnosis of cerebral angiostrongyliasis. This short review focuses on the history, incidence, and laboratory diagnosis of angiostrongyliasis in Thailand.

What is considered to be the first case of human parastrongyliasis (angiostrongyliasis) worldwide is described from a patient in Ceylon (Sri Lanka) in 1925. It also predates the description of the parasite in humans by Chen (1935).

Most of the major contributions of Americans to knowledge of poultry parasites have been made in the last 100 years. Factors responsible for this tardiness differed somewhat according to the disease. The first parasitic diseases to receive attention were usually those with distinctive characteristics as well as serious consequences, such as "gapes" and lousiness. Since helminths could usually be readily observed, whereas protozoa could be observed only by persons skilled in microscopy, disorders attributable to the former usually received attention earlier than did protozoan diseases. The control of ectoparasites, before the use of modern insecticides, became vastly simplified as mechanical incubators and brooders replaced the hen, and as the birds were provided with better housing. The major contributions of Americans to our understanding of parasitic diseases of poultry are detailed for five disorders attributable to helminths, and two attributable to protozoa. The latter are histomoniasis of turkeys and coccidiosis of chickens. No attempt has been made to evaluate the impact of contemporary research.
