Studies of pairs of Salmonella enterica serovar Enteritidis isolates from different poultry flocks showed that phage type (PT) 7 may be derived from PT 1, 4, and 6. The conversion appeared to be associated with loss of lipopolysaccharide. It is concluded that PT 7 may be of little value as an epidemiological marker of S. enterica serovar Enteritidis.
对来自不同家禽群的肠炎沙门氏菌肠炎血清型分离株进行的研究表明,噬菌体分型(PT)7可能源自PT1、4和6。这种转变似乎与脂多糖的缺失有关。得出的结论是,PT7作为肠炎沙门氏菌肠炎血清型的流行病学标志物可能价值不大。
