The number of Salmonella enteritidis isolations started to rise in humans, eggs and egg products in 4 territories out of the examined 9 territories of Russia in 1986. The spread of S. enteritidis infections was connected with the consumption of hen's eggs as it was demonstrated by the analysis of the local outbreaks. Phage type of 1142 S. enteritidis strains isolated in Russia was determined using the Hungarian typing scheme. The strains were typable in 95.3% and 12 phage types were found. Phage type 1 was the most frequent (86.7%) among human strains and also among strains originated from hen and egg products. The examined 18226 human S. enteritidis strains isolated in Hungary between 1984 and 1989 belonged to 24 phage types and phage type 1 was predominant, the incidence of this type varying between 69.3% and 93.2%. The strains were sensitive to antibiotics, multiresistant strains were found in 1%. Plasmid content was examined of 138 strains; a 38 Md plasmid was carried by all of them and a 96 Md plasmid was harboured by 11 antibiotic-resistant strains. The tested strains produced enterobactin but no aerobactin.
