All strains and serovars of Salmonella enterica such as serovar Typhimurium, Enteritidis, Dublin, Typhi, etc. were found to carry the Salmonella enterotoxin determinant stn as far as examined in PCR and hybridization studies. However, using MDCK cells for testing the toxicity of the strains under investigation, only a limited number of stn positive strains revealed phenotypically the Salmonella enterotoxin Stn. In contrast to S. enterica, other Enterobacteriaceae including Salmonella bongori were found neither genotypically nor phenotypically Stn toxin positive.
在PCR和杂交研究中，发现所有肠炎沙门氏菌的菌株和血清型，如鼠伤寒血清型、肠炎血清型、都柏林血清型、伤寒血清型等，均携带沙门氏菌肠毒素决定簇stn。然而，使用MDCK细胞检测所研究菌株的毒性时，只有有限数量的stn阳性菌株在表型上显示出沙门氏菌肠毒素Stn。与肠炎沙门氏菌相反，包括邦戈尔沙门氏菌在内的其他肠杆菌科细菌在基因型和表型上均未发现Stn毒素阳性。
