Frederick Griffith conducted an experiment using 2 different strains of the bacterium Streptococcus pneumoniae. As you can see in the diagram below, the S strain bacteria killed the mice and the R strain bacteria did not kill the mice. What is the difference in structure between the S and R strains? Why does the dead mouse contain living S strain when only dead S strain was injected?

MICROBIOLOGY Help. those are practice questions NOT graded ones! :) --------- is the product generated by ornithine decarboxylation, and it smells like -------------. Which of the following is added to decarboxylase media that turns purple when conditions are alkaline/basic and yellow when conditions are acidic? Lysine, Glucose, ornithine, Broom Cresol Purple, Phenol red An acidic environment is inhibitory to decarboxylase activity. true or false? Lysine decarboxylase media is yellow after incubating an organism in it at 37 degrees for 24 hours. Which of the following can be interpreted from this result? The organism did not grow so lysine decarboxylase activity could not be determined. The organism is negative for lysine decarboxylase. The media is too acidic to determine lysine decarboxylase activity. The organism is positive for lysine decarboxylase. Mineral oil is added to the top of decarboxylase media so more oxygen is available for glucose fermentation. True or False?
