About half (49%) of strains of Staphylococcus aureus isolated from poultry were non‐typable with the international human set of phages, and 55% were biotype B according to the biochemical identification scheme of Hájek & Maršálek (1971, 1973). A furthest neighbour clustering strategy and principal coordinate analysis based on 17 biochemical tests made clear distinctions between biotype B strains and a group of biotype A and intermediate strains. Overall 62% of strains were enterotoxigenic, the majority producing enterotoxin A. Significantly fewer intermediate strains than biotype A or B strains were enterotoxigenic. Starch gel zymograms of intracellular esterases showed a general correlation with the biotyping and phage typing results.
