Investigation of the source of neonatal Salmonella dublin infection of calves was undertaken by carrying out caesarean section of cows with a history of excretion of S dublin following either S dublin enteritis or S dublin abortion. No evidence of transplacental infection was detected but six of 10 animals showed evidence of excretion of the organism in the faeces, vaginal discharge or milk in the period immediately following parturition. The strong probability of early infection as a result of contamination of the environment is therefore suggested.
通过对有都柏林沙门氏菌肠炎或都柏林沙门氏菌流产病史且有都柏林沙门氏菌排泄史的奶牛进行剖腹产，对犊牛新生儿都柏林沙门氏菌感染的来源进行了调查。未检测到经胎盘感染的证据，但10只动物中有6只在分娩后立即出现粪便、阴道分泌物或乳汁中存在该菌的排泄证据。因此提示因环境污染导致早期感染的可能性很大。
