SUMMARY

272 isolates of Salmonella Enteritidis (111 isolated from frozen broiler chicken carcasses, 126 from human food and other biological materials involved in food poisoning outbreaks and 35 from different poultry materials) were selected for phage typing. From these, 111 were phage typed, 57.65 % being classified as phage type 4, 32.43 % as phage type 4a, 3.60 % as phage type 6a and 0.90 % as phage type 7, whereas 5.40 % samples were not phage typeable. The predominance of phage type 4 is in agreement with the results published worldwide, and reinforces the need for studies related to the epidemiological meaning of these findings
