Transmissible gastroenteritis (TGE) is a highly contagious enteric disease of swine, which became infrequent with the appearance of porcine respiratory coronavirus (PRCV). TGE was last reported in Hungary in 2013 and the virus has not been found since, therefore a serological survey was planned to estimate the level of protection against it. 908 sera of sows from 93 farms were selected together with 174 archive samples from one farm covering a wider age group. All samples were screened with an indirect immunofluorescence (IF) test with a positive result of 15.42% and 17.82%, respectively. All IF-positive samples were examined with a commercial ELISA, revealing seropositivity against PRCV in almost all cases. These findings should serve as a recommendation to not omit TGE from the diagnostics of diarrhoea in swine.
传染性胃肠炎（TGE）是猪的一种高度传染性肠道疾病，随着猪呼吸道冠状病毒（PRCV）的出现，这种疾病变得不常见了。TGE上一次在匈牙利被报道是在2013年，此后就再也没有发现过这种病毒，因此计划进行一项血清学调查来评估针对它的保护水平。从93个农场选取了908份母猪血清，以及来自一个农场的174份存档样本，这些样本涵盖了更广泛的年龄组。所有样本都用间接免疫荧光（IF）试验进行筛查，阳性结果分别为15.42%和17.82%。所有IF阳性样本都用一种商业ELISA进行检测，结果显示几乎所有病例都对PRCV呈血清阳性。这些发现应作为一项建议，即在猪腹泻的诊断中不要遗漏TGE。
