Dl. Baggesen et al., CORRELATION OF CONVERSION OF SALMONELLA-ENTERICA SEROVAR ENTERITIDIS PHAGE TYPE-1, TYPE-4, OR TYPE-6 TO PHAGE TYPE-7 WITH LOSS OF LIPOPOLYSACCHARIDE, Journal of clinical microbiology, 35(1), 1997, pp. 330-333
Studies of pairs of Salmonella enterica serovar Enteritidis isolates f
rom different poultry flocks showed that phage type (PT) 7 may be deri

loss of lipopolysaccharide. It is concluded that PT 7 may be of littl
e value as an epidemiological marker of S. enterica serovar Enteritidi
