How to write H. pylori

The CORRECT way to write H. pylori is:

                 H. pylori

Note the following:

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

INCORRECT ways to write H. pylori are:

• H. pylori (incorrect because it is not in italics)
• H.pylori (incorrect because there is no space after the dot)
• H. Pylori (incorrect because of uppercase "P")
• H. PYLORI (incorrect because of uppercase "PYLORI")
• h. pylori (incorrect because of lowercase "h")
• H.-pylori (incorrect because hyphen used instead of a space)

Please note in particular:

• Always use italics to write H. pylori
• Always use a single space after the dot (i.e. before "pylori") in H. pylori
• Always use an uppercase "H" in H. pylori
• Always use lowercase "pylori" in H. pylori
• Never use an uppercase "P" in H. pylori, not even in headlines or headings
• Never use uppercase PYLORI in H. pylori, not even in headlines or headings
• Never use a hyphen in H. pylori

To be absolutely correct:

• Write Helicobacter pylori 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: H. pylori
