You should NEVER assume anything in microbiology. An organism could be part
of normal flora in one instance and very pathogenic in another. Some people
carry organisms as part of their normal flora without any obvious signs or
symptoms, and yet these same organisms could be deadly in others. Look up
"Typhoid Mary".
