用不同剂量的鸡沙门氏菌、沙门氏菌、沙门氏菌和沙门氏菌对6个近交系的鸡进行肌肉接种。pullorum，或S.比较两组患者的死亡率和病死率。对于每种血清型，观察到不同品系的平均致死剂量存在很大差异：鼠伤寒沙门氏菌对S. gallinarum、鸡角藻S. pullorum和S.以及感感病品系。鼠伤寒沙门氏菌对其他血清型也更敏感。这些结果表明，可能有一个通用的机制，可能适用于所有血清型沙门氏菌在鸡。
Chickens of six inbred lines were inoculated intramuscularly with a range of doses of either Salmonella gallinarum, S. pullorum, or S. enteritidis, and levels of mortality were compared. For each serotype, large differences in mean lethal doses were observed for the different lines: Lines that had previously been shown to be resistant to S. typhimurium were also found to be resistant to S. gallinarum, S. pullorum, and S. enteritidis, and lines susceptible to S. typhimurium were also more susceptible to the other serotypes. These results suggest that there may be a general mechanism of resistance that may apply to all serotypes of Salmonella in chickens.
