The chart suggests the unknown organism is hemolytic. Choices A, B, and D are potentially hemolytic, while Micrococcus roseus (Choice C) is the exception, being less associated with hemolysis.
The chart's classification of the unknown organism as hemolytic indicates its ability to lyse or break down red blood cells. Among the given options, Staphylococcus aureus (Choice A), Staphylococcus epidermidis (Choice B), and Micrococcus luteus (Choice D) are potential hemolytic organisms, capable of causing hemolysis. These bacteria may exhibit beta-hemolysis, resulting in a clear zone around the colonies on blood agar.
However, Micrococcus roseus (Choice C) is not typically associated with hemolysis. Micrococcus species are often gamma-hemolytic or non-hemolytic, meaning they do not cause significant breakdown of red blood cells, and as such, they would not produce a noticeable zone of hemolysis on blood agar.
In summary, based on the chart information, the unknown organism is likely hemolytic, and Micrococcus roseus (Choice C) stands out as the exception among the provided options, as it is less associated with hemolytic activity compared to the others.
The question probable may be:
Your unknown is a hemolytic according to the chart it could be all the following organisms except
A. S.aureus B. S . epidermidis C. M. roseus D. M.luteus
