Studies was the lysogenicity in a total of 70 strains of Escherichia coli isolated from birds. As many as 19 lysogeneic strains were isolated, yielding 19 phages that had the signature of lysogenic strains. Two serologic groups of phages were established by means of the neutralization reaction. It was found that phages 30 and 229, representing the two serologic groups of bacteriophages could lyse up to 44 per cent of the E. coli strains isolated from birds, 7 per cent of those isolated from calves, and 4 per cent of those from pigs. Out of 74 Salmonella strains, belonging to ten species, the same phages lysed two strains of Salmonella newport and 1 strain of Salmonella anatum. It is believed that phage lysis could be used to establish the source of infection and to evaluate the effectiveness of the prophylactic measures applied, incl. disinfection.
对从禽类中分离出的总共70株大肠杆菌进行了溶源性研究。分离出了多达19株溶源性菌株，获得了19种具有溶源性菌株特征的噬菌体。通过中和反应建立了两个噬菌体血清学组。发现代表这两个噬菌体血清学组的噬菌体30和229可裂解高达44%的从禽类中分离出的大肠杆菌菌株、7%的从犊牛中分离出的菌株以及4%的从猪中分离出的菌株。在属于十个物种的74株沙门氏菌菌株中，同样的噬菌体裂解了两株新港沙门氏菌和一株鸭沙门氏菌。据信，噬菌体裂解可用于确定感染源并评估所采取的预防措施（包括消毒）的有效性。
