Tiwu Zhang,
Chlamydia trachomatis is the specific bacterium that causes chlamydia. And I do remember reading something about Chinese doctors culturing a bacterium from the Chlamydia family. But I had thought that both European researchers and WHO (as well as CDC) had already identified the responsible agent as being a previously unknown variant of the coronavirus, one of the leading causes of the common cold. I think it was the European researchers that stated that any findings of chlamydia were secondary and coincidental to the coronavirus, as none of the patients in Europe or Canada had any evidence of chlamydia, or exposure to chlamydia. Chlamydia itself is not an uncommon social disease amongst promiscuous humans (or people who at one time in their lives were promiscuous) in the world, or even in people who are exposed to others in society where chlamydia is endemic in the local population, not necessitating sexual contact.
In any case, I think it's unlikely that any bacterium is responsible for SARS, because bacterium, unlike viruses, are relatively easy to spot and identify. For one thing, bacterium are many times larger than most viruses, and are usually easy targets for culture mediums. I also think that (most) bacterium respond to one or more antibiotics rather quickly, so even if the disease weren't knocked down quickly by antibiotics, doctors would usually expect to see some sort of change in the course of the disease with the application of a wide range of antibiotics in large doses once treatment began. As SARS failed to respond to antibiotics in all patients, and antibiotics were only marginally helpful in combination with antivirals, I would suspect that the agent was a virus, not a bacterium.
But what do I know??? <g>
Good luck to you...
