We lately detected that some important errors were introduced during the production of the last version of our article [1] regarding some Greek letters used to classify intimin subtypes. We regret that these errors were introduced in the final version.

In Table 1, the Greek letters used to nominate intimin subtype omicron should be corrected (ο instead of μ). Furthermore, intimin upsilon (Greek letter- υ) appears with a wrong symbol (ν). Please, find below the corrected version of Table 1.

In "Results and Discussion" (Page 3, Paragraph 1) and in "Methods" ("Typing of intimin genes", Page 8), intimin upsilon (Greek letter- υ) appears again with a wrong symbol (ν).
