質問 2

Listeria monocytogenes is the correct answer. The motility agar is showing motility at the top of the tube, but not deeper; typical of this catalase-positive, gram positive bacillus. Streptococcus agalactiae would be catalase negative and a coccus. Erysipelothrix rhusiopathiae would be H2S-positive and catalase negative. Escherichia coli is a gram negative bacillus.

This Gram-positive bacillus grew as a diffusely beta-hemolytic colony from a newborn. It was catalase positive and had tumbling motility on a hanging drop preparation. This is how it appeared on triple sugar iron agar and motility medium. What is the most likely diagnosis?

（A）Erysipelothrix rhusiopathiae

（B）Listeria monocytogenes

（C）Streptococcus agalactiae

（D）Escherichia coli

質問 5

Gating sets up boundaries around a subset of data points to segregate those events for analysis.
Gating the proper cell population is crucial for flow cytometric analysis. The CD marker information presented on the histogram data is only representative of the cells inside the gate.

（A）Non-gated

（B）Gated

質問 8

In excess triglycerides, the triglycerides reduce the amount of cholesterol in LDL particles producing small dense LDL molecules. Because of size and density, these molecules more easily enter damaged endothelium and vessel walls and are more easily incorporated as plaque is formed.
Which statement best describes small dense LDL particles that can occur in atherogenic dyslipidemia?

（A）Small dense LDL molecules transport more cholesterol and thus are more atherogenic

（B）Small dense LDL molecules are less atherogenic than larger, less dense or buoyant LDL particles because they are metabolized faster

（C）Small dense LDL molecules are more atherogenic because they can more easily move into the endothelium and vessel wall
