Hello, I'm not an expert in English or in Microbiology, but I would recommend strengthening the sentence begining with: "Being a non-pathogenic bacteria," ...
Here is what I think. The subsection is called "pathology." Since you say it is non-pathogenic, you should say that in the first sentence, then go on to say how it is similar to P. aeriginosa (sp?). Or, say both in the first sentence - ... ex "P. putida is considered nonpathogenic, but is similar in genome to p. aeriginosa and a handful of infections have been reported..."
