Abstract: 20 adult rats were examined and we found Trichosomoide crassicauda worms in 13 instances. which harbord from 3~14 with an average of 7 worms. All are femiles. Morphotropy and culture in vitro of eggs have been invested. Worms is long in 10.31± 0.36mm, wide in 15.50± 6.48μm; eggs are elliptic, sized (63.67±0.95)×(36.67 ±1. 39) μm. 80 eggs are cultured in a very simple media (Nacl 0.9%%+penicilline), 48 hours later, 20 eggs died; 72 hours, half of them died; 96 hours, only 4 survived; 120 hours,all died. It showed that eggs can live on a longer time even through they are cultured in a simple media.
