10 Questions
Which statement best describes the characteristic of obligate intracellular bacteria mentioned in the text?
They lack many biosynthetic pathways and depend on the host cell for ATP and other molecules.
In the context of obligate intracellular bacteria, which best describes the role of Coxiella burnetii?
It is an obligate intracellular bacterium causing acute and chronic infections.
Which process is involved in the chlamydial growth cycle according to the text?
Binary fission of reticulate bodies (RB) inside host cells.
What is a characteristic of obligate intracellular pathogens?
They are shielded from humoral antibodies
How do obligate intracellular pathogens achieve invasion?
By entering host cells and reproducing
What differentiates obligate intracellular pathogens from facultative intracellular pathogens?
Can only reproduce inside host cells
What is the compartment where C. burnetii replicates inside alveolar macrophages?
Phagolysosome
Which of the following is NOT an obligate intracellular bacterium from the text?
Bacillus anthracis
How does C. burnetii escape immune detection as described in the text?
By replicating within a compartment similar to a phagolysosome
What is the main method through which host cells defend against intracellular pathogens?
Recognition of pathogens through PAMPs
Learn about how Listeria monocytogenes moves from one host cell to another, allowing infections to reach other organs. Explore the process of invasion, escape from phagosome, replication in the cell cytosol, and spread by actin-based motility.
