EVALUATION OF SEVEN EXPERIMENTAL STAPHYLOCOCCAL PHAGES

Abstract

The percentage of strains of Stn plrylococcus .t1lln'us that can be typed with the basic set phages has fallen in recent years (1,2)). It appears, therefore, that all increasing proportion of stcphvlococci, for whatever reason, arc unsuscepriblc to the basic set phages and it is essential that new phages be introduced if the situation is to be improved. Seven new phages have ben issued by the International Reference Centre on Phage-Typing of Staphylococci, to several reference laboratories so that the value of these phages could be assessed. This is the report of our laboratory at the School of Public Health, Section of Staphylococcal PhageTyping, on the cfl'ccrivcucss of these new phages.
