[Salmonella serovars defined in Poland]

One hundred and sixty nine serovars of Salmonella, belonging to 28 different O groups, were defined in the National Salmonella Centre. All the serovars were isolated in Poland. Above 70% (121/169) of them belonged to five O groups--O:4 (31 serovars), O:7 (28 serovars), O:8 (27 serovars), O:3,10 (20 serovars) and O:9 (15 serovars). Other O groups were represented by some (1 to 8) serovars. All the serovars were described according to the changes in taxonomy of the genus Salmonella and in serovars nomenclature. These changes, proposed by WHO Collaborating Centre for Reference and Research on Salmonella (Paris, France), reflect the recent advances in Salmonella taxonomy.
