You mean... There’s something to that evolution stuff after all?

. . . . .

Absolutely. A bacterium morphed into a bacterium.

Again!

It just gets more exciting with every report.

Your comment would be more meaningful if "bacterium" was all one species, or even one genus. But that's not the case. Check out the following table:

The Phyla of Bacteria (as taken from Bergey's Manual of Systematic Bacteriology 1st Ed.)
Name of Phylum Number of Species Number of Genera
Aquificae 27 12
Xenobacteria 29 11
Chrysogenetes 1 1
Thermomicrobia 13 6
Cyanobacteria 78 62
Chlorobia 17 6
Proteobacteria 1644 366
Firmicutes 2474 255
Planctomycetes etc. 13 5
Spirochaetes 92 13
Fibrobacter 5 3
Bacteroids 130 20
Flavobacteria 72 15
Sphingobacteria 76 22
Fusobacteria 29 6
Verrucomicrobia 5 2

As you can see there is a great deal of latitude for change within "bacterium" -- such that analyses like the one reported here can easily demonstrate speciation (macroevolution) while still dealing with "bacteria."

Here’s something to ponder: e.Coli, a bacteria with several varieties, divides about every 15 minutes. Now imagine how many generations that would be over the past hundred years.
Of course it’s been around much longer but this is a nice round figure. Back of an envelope calculation, A hundred years of e. Coli generations is like about a hundred million years of human generations.
And yet after all these millions of generations Mr. e. Coli is just a bacterium. I don’t think he’s ever going to be anything else.

It sounds like you may have read the article.

From the article: Scientists studied 131 strains of Bacillus simplex and found that bacteria on different slopes have evolved differently, forming different 'ecotypes' of the same species .
