Can cause disease.
But then surely most strains of bacteria would be considered pathogenic?
Probiotics such as Lactobacillus have the potential to cause infection, but aren't considered pathogenic?

Think of the name - "pathogenic" the ability to generate pathology.

We live with various pathogenic bacteria on and in our bodies and survive quite nicely. Something like lactobacillus would be a potential pathogen.

So is lactobacillus defined as a pathogen (not potential) or not?

And do you have any examples of non-pathogenic bacteria?

Lactobacillus is a natural commensal bacteria of the gut and genital tract but can also behave as a pathogen

Most bacteria are non-pathogenic. With new DNA fingerprinting technology and microbiome research we are realising there are a LOT more bacteria than we first thought.

A pathogen is any micro-organism that can cause disease. Many commensal bacteria can become pathogenic if given the opportunity (opportunistic pathogens). For example, there are lots of bacteria that make up the flora in the gut and are usually commensals, however, suppose the gut perforates and the bacteria go into the abdominal cavity, this can cause infection.
