The authors pay attention to the mode of transmission of salmonelloses in children under two years of age, where the highest specific morbidity was recorded. Using phenotypic (biochemical properties, sensitivity to antibiotics, phagotype) and genotypic properties (presence of plasmids) they examine five sporadic and seven epidemic incidences of salmonelloses in young children. The most frequent agent is Salmonella enteritidis, phagotype 8, plasmid 55 kb. Strains of S. enteritidis are isolated from the faeces of affected children, their family contacts, from food and the sick child's environment. Alimentary transmission by the incriminated food was detected from epidemic incidence where the vehicle were confectionery products contaminated by S. enteritidis. In sporadic cases in families also direct and indirect contact may have participated in the transmission of infection.
作者关注两岁以下儿童沙门氏菌病的传播方式，该年龄段记录到的特定发病率最高。他们利用表型特性（生化特性、对抗生素的敏感性、噬菌体型）和基因型特性（质粒的存在情况），对幼儿中五例散发病例和七例流行病例的沙门氏菌病进行了研究。最常见的病原体是肠炎沙门氏菌，噬菌体型8，质粒55 kb。肠炎沙门氏菌菌株从患病儿童的粪便、其家庭接触者、食物以及患病儿童的环境中分离得到。在流行病例中，通过受污染食物的经口传播被检测到，传播媒介是被肠炎沙门氏菌污染的糖果产品。在家庭散发病例中，直接和间接接触也可能参与了感染传播。
