Abstract: Objective We summarized and analyzed the scientific thinking and related treatment methodcaused by occasional sick large animals in scientific research to provide practical reference to handle thesimilar conditions. Method In a study of techniques related to laparoscopic porcine livertransplantation, the liver donor pig developed a sudden respiratory cardiac arrest after routine anesthesiavia the marginal ear vein. Therefore, the cyst wall cells were cultured and the cyst wall tissues wereexamined pathologically. Result The cyst wall cells showed a grape tandem suspension growth. The smear staining result showed that the cultured cyst wall cells were mainly inflammatory cells. The cystwall tissue was mainly composed of granulation tissue and fibrous tissue, which was a chronicinflammatory hyperplasia. Conclusion The following enlightenments can be obtained from the occasionalencounter of this sick pig: ①routine animal health examination should be performed before large animalexperiments; ②researchers should have a high sensitivity to infectious disease protection; ③researchersshould maintain a highly scientific sensitivity to the occassional situations during the experiment;④comprehensive pathological samples should be retained during the experiment; ⑤ the monitoring ofanimal health status in the farm should be improved
