Como escrever E. coli?

Minha eterna briga com os alunos: o respeito à lingua morta - latim. 

ADOREI este post do Horizon Press - segue na íntegra, em inglês, como no original (acesse aqui):

The CORRECT way to write E. coli is:

E. coli

Note the following:

• The uppercase "E" and the lowercase "coli" in E. coli
• The dot (period, full stop) after the "E" in E. coli
• The single space after the dot in E. coli
• E. coli should be in italics

INCORRECT ways to write E. coli are:

• E. coli (incorrect because it is not in italics)
• E.coli (incorrect because there is no space after the dot)
• E. Coli (incorrect because of uppercase "C")
• E. COLI (incorrect because of uppercase "COLI")
• e. coli (incorrect because of lowercase "e")
• E.-coli (incorrect because hyphen used instead of a space)

Please note in particular:

• Always use italics to write E. coli
• Always use a single space after the dot (i.e. before "coli") in E. coli
• Always use an uppercase "E" in E. coli
• Always use lowercase "coli" in E. coli
• Never use an uppercase "C" in E. coli, not even in headlines or headings
• Never use uppercase COLI in E. coli, not even in headlines or headings
• Never use a hyphen in E. coli

To be absolutely correct:

• Write Escherichia coli the first time you refer to the microbe in your report, article, or story
• Everywhere else in the same report, article, or story use the abbreviated form: E. coli
