Question

Select the TRUE statements regarding Aggregibacter actinomycetemcomitans?

1) Aggregibacter actinomycetemcomitans is a gram-negative bacterium
2) Aggregibacter actinomycetemcomitans is a gram-positive bacterium
3) Aggregibacter actinomycetemcomitans is a virus
4) Aggregibacter actinomycetemcomitans is a fungus

Answer 1

The true statement about Aggregibacter actinomycetemcomitans is that it is a gram-negative bacterium, not a gram-positive bacterium, virus, or fungus.

Step-by-step explanation:

The TRUE statement regarding Aggregibacter actinomycetemcomitans is that it is a gram-negative bacterium. This organism demonstrates characteristics consistent with a gram-negative bacteria, such as a cell wall that contains little peptidoglycan but has an outer membrane. It is not classified as a gram-positive bacterium, a virus, or a fungus. Interestingly, the taxonomic class Actinobacteria comprises the high G+C gram-positive bacteria, which differ distinctly from Aggregibacter actinomycetemcomitans. Gram-positive bacteria, like those in the class Actinobacteria, have a high content of guanine and cytosine nucleotides in their DNA, whereas Aggregibacter reflects the typical gram-negative characteristics.
