Infection with transmissible gastroenteritis virus (TGEV) was present in some pigs on arrival at a feeder pig farm and was well established three weeks later. TGE infection preceded Mycoplasma hyopneumoniae infection, which was not detected until three weeks after arrival. Severe lesions of enzootic pneumonia were observed at the end of the fattening period.A trial was subsequently done in six-week-old-pigs in order to evaluate the potentiating effect of TGEV infection on experimental M. hyopneumoniae infection. The effects of mycoplasmal infection were aggravated when associated with TGEV infection as determined by the extent of pneumonic lesions observed two weeks later.
一些仔猪抵达育肥猪场时就感染了传染性胃肠炎病毒（TGEV），三周后感染情况已很严重。TGE感染先于猪肺炎支原体感染，后者在仔猪抵达三周后才被检测到。育肥期末观察到了严重的地方性肺炎病变。随后在六周龄仔猪中进行了一项试验，以评估TGEV感染对实验性猪肺炎支原体感染的增强作用。根据两周后观察到的肺部病变程度确定，当与TGEV感染相关联时，支原体感染的影响会加重。
