Bacteriophage typing was performed on 1911 S. agona, lactose-fermenting strains. These strains were isolated from hospitalised newborns and neonates patients. Out of 1911 strains 98.8% were typable by means of phage set prepared for strains differentiation of Salmonella agona showing typical biochemical properties. It was shown that in 16 provinces from which the strains were obtained in 1983-1985 type V (49.5%) and type XI (25.4%) prevailed. Subtypes VA and VB were distinguished within type V. Altogether 20.3% of strains were classified as belonging to these subtypes. Their lytic reaction was weaker with phages 3, 4, and 9 with the characteristic range of phage type V strains. Among tested strains types I, XIII, and XVI were also represented composing 2, 6, 0, 9, and 0.3% of total number of strains respectively. 1.5% of strains were nontypable and 0.2% showed lytic reactions different from that included in up to now used scheme of typing. It can be concluded that lactose-fermenting S. agona strains show susceptibility to lowered number of phages than typical for Salmonella species strains. It seems that differentiation of this atypical biochemical variant of S. agona with, the use of phage set used up to now may be also usefull in practice as it is the case in respect to strains with typical biochemical properties.
对1911株发酵乳糖的阿哥纳沙门氏菌进行了噬菌体分型。这些菌株分离自住院新生儿和新生儿患者。在1911株菌株中，98.8%可通过为具有典型生化特性的阿哥纳沙门氏菌菌株鉴别而制备的噬菌体组合进行分型。结果表明，在1983 - 1985年获得菌株的16个省份中，V型（49.5%）和XI型（25.4%）占主导。在V型内区分出了VA和VB亚型。共有20.3%的菌株被归类为这些亚型。它们对噬菌体3、4和9的裂解反应较弱，而这些噬菌体是V型菌株的特征性范围。在所测试的菌株中，I型、XIII型和XVI型也有出现，分别占菌株总数的2%、6%、0.9%和0.3%。1.5%的菌株无法分型，0.2%的菌株表现出与目前使用的分型方案中所包含的裂解反应不同的反应。可以得出结论，发酵乳糖的阿哥纳沙门氏菌菌株对噬菌体的敏感性低于沙门氏菌属典型菌株。看来，对于这种具有非典型生化变异的阿哥纳沙门氏菌，使用目前的噬菌体组合进行鉴别在实践中可能也是有用的，就像对具有典型生化特性的菌株一样。
