OCCURRENCE OF SALMONELLA-ENTERICA SEROTYPE ENTERITIDIS PHAGE TYPES INTHE SLOVAK-REPUBLIC

Phage typing of 741 isolates of Salmonella enterica serotype Enteritid is from the Slovak Republic in 1995 has been carried out using the sch eme of Ward and colleagues (1987). 202 strains (51 isolated from food) were from 9 outbreaks, 536 isolates were from sporadic cases and 3 is olates were from nosocomial infections of new-born babies. 704 isolate s (95%) from all sources were typeable and belonged to 7 different pha ge types (PTs). PT8 was the phage type most frequently identified (72. 6%). Other epidemiologically relevant phage types were PT2 (8.5%), 4 ( 7.9%) and 1 (4.2%). With an incidence of 1.3-0.1% isolates of PTs 21, 6, 9 were found. 26 (3.5%) isolates were designated RDNC and 11 (1.5%) were untypeable.
