Abstract

|
Eleven percent of 128 soil samples examined in Seoul area for Toxocara canis eggs were positive. In experimenta: observation, 34 larvae were collected from 10 mice which have been infected with total 110 infective stage eggs obtained from soil samples and cultured in the laboratory room. Another group of mice was infected with larvae from mice and examined for reinfectivity test, and some larvae were detected in the liver tissue on the 2nd day after infection.
By hisotological examination, an eosinophilic abscess was observed in the _center of a typical granuloma in the liver on the 21st day-after infection. It suggests that the larvae transmitted from another paratenic host is more pathogenic.
