在挪威东南部莫斯市、挪威中西部的阿斯科伊、卑尔根和奥斯市以及挪威西南部和中部的5个市的320只刺猬中调查了粪便携带沙门氏菌的情况。莫斯的采样是在人类沙门氏菌病暴发后一年进行的，而阿斯科伊、卑尔根和奥斯的采样是在人类暴发期间进行的。两次暴发均由鼠伤寒沙门氏菌引起4，5，12：i：1，2。在挪威西南部（01115）和中部（0/24）的刺猬中未检测到沙门氏菌。在Jeloy和阿斯科伊、卑尔根和Os的采样动物中，分别有39%（39/99）和41%（34/82）携带S。鼠伤寒4，5，12：i：1，2.两个疫区的人和刺猬分离株的PFGE图谱完全相同。S.与其他地方捕获的刺猬相比，在饲养场所采样的刺猬中发生了鼠伤寒。感染沙门氏菌的刺猬种群最有可能构成两次人类疾病暴发期间的主要感染源，挪威刺猬被认为是沙门氏菌的储存宿主。鼠伤寒4，5，12：i：1，2.
Faecal carriage of salmonella was investigated in 320 hedgehogs from Moss municipality in south-eastern Norway, Askoy, Bergen and Os municipalities in central-western Norway, and five municipalities in south-western and central Norway. The sampling in Moss was carried out I year after a human outbreak of salmonellosis, whereas the sampling in Askoy, Bergen and Os was carried out during a human outbreak. Both outbreaks were caused by Salmonella Typhimurium 4,5,12: i: 1,2. No salmonella were detected in the hedgehogs from south-western (01115) and central (0/24) Norway. Thirty-nine percent (39/99) of the animals sampled on Jeloy, and 41% (34/82) of those from Askoy, Bergen and Os, carried S. Typhimurium 4,5,12: i: 1,2. The PFGE profile of isolates from hedgehogs and human beings were identical within each of the two outbreak areas. A significantly higher carrier rate of S. Typhimurium occurred among hedgehogs sampled at feeding places, compared to those caught elsewhere. The salmonella-infected hedgehog populations most likely constituted the primary source of infection during both of the human disease outbreaks, and the Norwegian hedgehog is suggested as a reservoir host of S. Typhimurium 4,5,12: i: 1,2.
