Which of the following bacterial genera is NOT described correctly?
A
Escherichia: Gram-negative rods commonly found in the human intestine.
B
Staphylococcus: Gram-positive cocci that often form clusters.
C
Bacillus: Gram-negative rods that form endospores.
D
Clostridium: Gram-positive, anaerobic, spore-forming rods.
Guida verificata passo dopo passo1
Review the characteristics of each bacterial genus listed to determine if the description matches the known microbiological traits.
Recall that Escherichia species are Gram-negative rods commonly found in the human intestine, so this description is correct.
Remember that Staphylococcus species are Gram-positive cocci that often form clusters, which matches the description given.
Consider Bacillus species: they are actually Gram-positive rods that form endospores, so describing them as Gram-negative rods is incorrect.
Verify that Clostridium species are Gram-positive, anaerobic, spore-forming rods, which aligns with the description provided.
