RESUMEN

Specificity of antibodies in cerebrospinal fluid (CSF) of human cerebral gnathostomiasis cases were examined by indirect fluorescent antibody technique against paraffin sections of Gnathostoma spinigerum larva. Specific greenish fluorescence was observed at cuticle, esophagus, muscle cells, intestinal cell cytoplasm and microvilli. CSF of confirmed cerebral cysticercosis cases gave fluorescence mostly at the cuticle. It is suggested that parasite-specific antigen may be present on intestinal cell microvilli and CSF would be a good source of antibodies in studying specificity of antibodies to gnathostome infections.

RESUMEN

Indirect fluorescent antibody test (IFAT) was performed on sections of Gnathostoma spinigerum advanced third-stage larva with gnathostomiasis, angiostrongyliasis, trichinosis, strongyloidiasis and cysticercosis sera. Positive fluorescence was observed with the first three sera. Fluorescence was associated with the anterior part of the esophagus, surface of the cuticle and cytoplasmic granules of the intestine. Absorption of sera with gnathostome antigen did not elicit fluorescence. The results suggest that substances secreted from the esophagus and intestine constitute antigens in excretory-secretory products of the larva.

RESUMEN

During April, 1973, and outbreak of trichinosis occurred in Mae Sruay District, Chiang Rai Province, about 900 kilometers north of Bangkok, Thailand. Thirty-one persons were involved, of whom 27 (20 males, and 7 females), ranging in age from 9 to 72 years, were questioned. One adult female died before being brought to hospital. All subjects gave a history of having consumed raw pork in the form of "lahb" and "nahm", favourite dishes of the northern Thai. Beginning the third week after exposure, all developed fever and myalgia. Other less common complaints were diarrhoea and oedema of extremities and palpebral skin. Leucocytosis was revealed in 37% and 55% had eosinophilia exceeding 20%. Nineteen patients had hookworm and Opisthorchis infections. About 63% were skin test positive with Trichinella antigen. Eight patients were admitted to hospital; muscle biopsy was done on one serious case and trichina larvae were detected.
