Microbiology: Normal flora versus Pathogens

This video describes how to tell the difference between normal flora/bacteria and pathogenic colonial growth on cultures from various body sites.

How do you know what to culture from a specimen's 24 hour growth? Watch and find out 😉

Thank yofor your video. Do we do Sensi for haemophilus?

[ahmedelsakka]

so if someone has sore throat and tonsillitis, and on culture it revealed strept pyogen, how do i know if it is the pathogenic or the normal flora one ?? because strept pyogen is normal flora of throat

How can you count the colonies? and which colonies can be counted? Do you count the colonies in zone 1 or zone 4? Many Thanks

Streptococcus pneumoniae is not normal flora of mouth or throat

Why can't u just look in the actual blood itself under a microscope and see these organisms in the blood. Vs trying to get it to grow for regular eye view?

Thank you so much for this. Struggling with GRN in my clinical microbiology class, (I wish there were explanations like this)
