Question

match each term to the correct definition (module 7).

endotoxins are large molecules found in the cell wall of:
endotoxins are also called pyrogens because they:
in a gram stain, gram-negative bacteria stain:
in a gram stain, gram-positive bacteria stain:

options:
corrective maintenance activities
purple
pink
preventive maintenance
gram-negative bacteria
induce a fever

Explanation:

Match endotoxin cellular location

Endotoxins (lipopolysaccharides) are structural components located in the outer membrane of the cell wall of Gram-negative bacteria.

Match pyrogen definition

Pyrogens are substances that produce fever. Therefore, endotoxins are called pyrogens because they induce a fever.

Match Gram-negative stain color

In a Gram stain procedure, Gram-negative bacteria lose the crystal violet-iodine complex during decolorization and take up the counterstain safranin, staining pink.

Match Gram-positive stain color

Gram-positive bacteria retain the primary crystal violet-iodine complex during decolorization, staining purple.

Answer:

• Endotoxins are large molecules found in the cell wall of: Gram-negative bacteria
• Endotoxins are also called pyrogens because they: Induce a fever
• In a gram stain, gram-negative bacteria stain: Pink
• In a gram stain, gram-positive bacteria stain: Purple
