RDP: what does (T) mean in sequence identifier?

[bio_informatics]

Hi There,
I'm downloading sequences from RDP for genera, and species I'm interested in. Upon downloading I see few sequence identifiers have (T) in them. Example:

>S002232093 Dialister pneumosintes (T)
>S000446390 Dialister micraerophilus (T)

I'm unable to find its information in Help page, or RDP wiki.

Any pointers would be great.

Fairly sure that (T) stands for type strain - if you filter, selecting only type strains, all you see are sequences with a (T) subscript.

Ah, I see. In the beginning from the options:
Strain - type, non type, both

I selected both in radio button.

Thank you very much for your prompt reply, and helping me with this. :-)
