Effect of Sodium Chloride on the Heat Shocked Staphylococci

Abstract
|
|
|
Heat-shocked staphylococci at 60℃ were inoculated on media containing varying concentrations of sodium chloride, and the effect of sodium chloride on the growth of these organisms was studied with the following results.
1. Heat-shocked staphylococci for 16 to 24 minutes formed small numbers of colonies on nutrient agar, but those shocked for 26 minutes formed no or only negligible numbers of colonies.
2. The colony formation on brain heart infusion agar was almost the same as that on nutrient agar.
3. The time of heat shock for acriflavine-resistant staphylococci was prolonged than that of sensitive strains in the colony formation, but lysozyme-resistant strains showed almost the same attitude with the sensitive strains.
4. The time of heat shock to form colony on media was shortened as the concentration of sodium chloride increase.
