[Grammar] "Contra". In italics?

[Habituellement]

Hello everyone.
I would like to know whether it is necessary to write "contra" with italics, in the following kind of sentence.

This reading of the Tractatus Logico-Philosophicus [this is a book from Wittgenstein] affirms, contra a great many interpretations, that Wittgenstein endorses a realist metaphysics.

Unless I am mistaken, "contra" is a latin word. Is it, for that reason, necessary to use italics?

Thank you for your answer.
Regards.

I'd use italics.

It's not necessary, no. But I think I probably would.

I would use italics because it's not a Latin word that's been wholely adopted into English. A word such as "versus" would not need to be italicised because (almost) everyone knows what it means.
