NO son plates, son TSA dishes (you can check it in google).

I went to the congress and saw the dishes in the slide (it was an interpretation)

From my limited understanding of microbiology: A culture is grown or cultivated ON a 'plate'; a 'plaque' is what is found IN the culture on that plate. I think that the sentence below from Cristina's reference illustrates this. And again one of the definitions of 'plaque' from my basic dictionary: "a clear area in a bacterial culture produced by destruction of cells by a virus" [and bacteria, too, according to the reference below].

These sentences are from the reference Cristina has posted below:

Plates from a sample are examined for plaque formation (zones of bacterial host lawn clearing). The plaques are counted and summed for all plates from a single sample.

Plates are not Plaques.
