hi all;

I found a definition for genus Prevotella saying that it was under the Bacteroides species but after 1990 it became a separate genus from the bacteroides. that's understandable!!!!!!!!!!!!!!

Using Bacteroides as a marker to identify the nonpoint and point sources of fecal contamination in the water, in these literatures they always write Bacteroides-Prevotella marker. what do they mean by that? do they mean that both the Bacteroides and prevotella species are used as markers or they still treat Prevotella as one of the Bacteroides species?

 

I would mostly believe the first assumption!!!!!!!!!!

your clarification is highly appreciated

 

thanks

First, please use less exclamation marks.

Second, as you correctly noted, Prevotella and Bacteroides were initially regarded as one genus. As such the diagnostic tools used to identify them (usually specific 16s primers) were not able to distinguish between them.
