Abstract

There have been several reports on the relationship between toxocariasis and eosinophilia, but all have been limited to the areas of Seoul or Gangwon-do. In the present study, we investigated the seroprevalence of toxocariasis among eosinophilia patients in Chungcheongnam-do, the central district of Korea. Among the 101 patients tested, 51 (50.5%) were identified as positive by Toxocara ELISA, and 46 (45.5%) were confidently diagnosed with toxocariasis because of absence of any other cause of eosinophilia. Whereas 22 of 42 seropositive patients (52.3%) had a recent history of consuming raw livers, especially the cow liver, only 1 of 25 seronegative patients (4%) had done so (P<0.01). From these results, we could confirm that toxocariasis is related to eosinophilia, and infer that ingestion of raw cow liver plays a vital role in the transmission of toxocariasis in Chungcheongnam-do.
