| Sumario: | Trichinella spiralis is a parasitic disease in man, rat, pig, but can infect any carnivorous or omnivorous. When the meat or their derivates are contaminated with infective larvae (il) of T. spiralis pass to the stomach, their capsules are dissolved by the stomach juice, the larvaes are liberated in few hours, and then they pass to the near portion of the slim intestine in which they develop. The objective of the present work was to evaluate the intestine phase of T. spiralis in a murine model. Fourtyfive Long Evans rats were infected with 500 li approximately, then 3 rats were sacrificed everyday over a period of 15 days. A portion of duodenum, jejune and ileum were fixed in formaldehyde 10% and subsequently embeded in paraffin and dyed with hematoxilin-eosina. The rest of the slim intestine was cut and fractionated and incubated at 37 ºc for 2 hours; the supernadant was observed unde light microscopy. We observed that the implant of larvae was in the jejune and ileum. The adult females gave origin to approximately 60- 80 newborn larvaes (LRN) and subsequently were destroyed. The adult male had nonciliated sperm. |
