Chlamydiae are a phylum of bacteria that are obligate intracellular parasites. One of these is Chlamydia trachomatis, which causes the STD chlamydia (See related question "What is chlamydia?" for information on the STD.)
Bacteria in the chlamydia family that causes disease include C. trachomatis, C. psittaci, and C. pneumonia. There are other chlamdyia species that cause diseases in other animals, as well as species that cause no illness.

BlakeChlamydiae are a group of bacteria that can cause a variety of diseases in humans and animals, including the sexually transmitted infection chlamydia. They are classified as obligate intracellular pathogens, meaning they can only survive and replicate inside host cells. Chlamydiae are known for their unique developmental cycle that involves alternating between infectious elementary bodies and replicative reticulate bodies.

Where do chlamydiae get nutrients?
Chlamydiae are obligate intracellular bacteria that parasitize host cells for nutrients. They rely on the host cell's resources to multiply and survive, as they lack the metabolic machinery to produce their own nutrients.
What diseases are caused by chlamydiae?
Chlamydia trachomatis can cause sexually transmitted infections (STIs) such as chlamydia urethritis or cervicitis. Chlamydia pneumoniae is linked to respiratory tract infections, while Chlamydia psittaci can cause psittacosis, an avian disease that can be transmitted to humans.
What is the difference between a virus and a rickettsia?
Viruses are submicroscopic infectious agents that require a host cell to replicate. Rickettsia are a type of bacteria that are obligate intracellular parasites, meaning they can only survive and replicate inside host cells. Viruses lack the cellular machinery for metabolism and reproduction, whereas rickettsia have some cellular functions but still rely on host cells for survival.
