Aim: To identify phenotypes of S enteritidis isolated from eggs, chicken meat and infected humans in Antofagasta during the period 1997-2000. Material and Methods: PhP-S48 and phage typing were used to identify phenotypes of 33 S enteritidis strains, sixteen isolated from poultry and 17 from clinical sources. S enteritidis ATCC17036 was used as control strain. Results: Twelve biochemical phenotypes (BTs) including 4 common (C) and 8 single (S) were identified. BTs C1 y C3 containing 16 and 5 strains, respectively, accounted for 63.6% of the isolates. BT C1 was found in poultry and human sources in the period 1997-2000, and BT C3 was isolated from humans, in the period 1999-2000. Using phage typing, 5 phage types (PT) and 3 strains could be not typed (NTs). PT1 and PT21 were the dominant phage types, with 14 and 13 strains respectively. Strains of PT1 were isolated from poultry and human sources in the period 1997-2000. PT21 was found in poultry samples in the period 1997-1998 and in clinical samples, in the period 1997-1998. Combination of biochemical phenotypes and phage typing divided the strains into 5 phenotypes (BT:PT). Two phenotypes were the most frequently isolated, phenotype C1:1 with 8 isolates found in eggs and humans in 1999, and phenotype C1:21 with 5 strains isolated in 1997-1999. Conclusions: These results indicate the presence of one persistent and one recently emerged phenotype among S enteritidis in Antofagasta, Chile. PhP-S48 also provided information about a relationship among the strains (Rev Méd Chile 2003; 131: 837-45)info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.131 n.8 20032003-08-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872003000800002es10.4067/S0034-98872003000800002
