Taxonomy/phylogeny:
   
About 25 species have been described within in the genus Campylobacter and some of these are further divided into subspecies. This genus is closely related to the following genera: Sulfurospirillum, Arcobacter and Helcobacter. C. upsaliensis is closely related to C. helveticus and C. avium.
Legislation:

In Sweden, human campylobacteriosis is notifiable to the Public Health Agency of Sweden.

This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.
