Mesenteric lymph nodes were collected from healthy sow and slaughter hogs that had been kept in holding pens for an average of 10 and 2 days, respectively, before slaughter at an abattoir. Salmonella was isolated from 58.2% (67/115) of the sows and 31.3% (16/51) of the slaughter hogs. This difference in Salmonella prevalence was significant (chi 2 = 10.22, P less than 0.005); therefore, the hypothesis that there would be no significant difference in the infection rates of sows and slaughter hogs was rejected.
从健康母猪和屠宰猪身上采集肠系膜淋巴结，这些母猪和屠宰猪在屠宰前分别在饲养栏中平均饲养了10天和2天，屠宰地点为屠宰场。从58.2%（67/115）的母猪和31.3%（16/51）的屠宰猪中分离出了沙门氏菌。沙门氏菌患病率的这种差异具有统计学意义（卡方 = 10.22，P < 0.005）；因此，关于母猪和屠宰猪感染率不会有显著差异的假设被拒绝。
