what is the aseptic technique

The practice and/or process of preventing contamination

why do we use the aseptic technique

it ensures that you don’t introduce contaminants into a specimen and that you don’t spread infectious agents to yourself or laboratory surfaces

how do you streak a bacterial plate

put agar on a petri dish, label the dish, pick up a bacterial colony using an inoculating loop, then smear it on the agar

why do we streak bacterial plates

The goal of this procedure is to obtain isolated bacterial colonies

what is this

what is this

gram positive

would it be gram negative or positive if a bacteria slide was purple

gram positive

would it be gram negative or positive if a bacteria slide was pink

gram negative

why is gram negative more dangerous

they have an additional layer called lipopolysaccharide that can have toxic effects

what is the gram stain

a test that differentiates bacteria into one of two groups based on the composition of their cell wall
