What is the difference between aerobic and anaerobic blood culture?
Blood cultures are drawn into special bottles that contain a special medium that will support the growth and allow the detection of micro- organisms that prefer oxygen (aerobes) or that thrive in a reduced-oxygen environment (anaerobes). Multiple samples are usually collected.

What is anaerobic and aerobic culture?
Most bacteria can grow in oxygen. They are called
aerobic bacteria
and usually are found in wounds close to the skin surface (superficial). Bacteria that cannot grow in the presence of oxygen (anaerobic) usually are found in deeper wounds and abscesses.
Why is the order of collection so important?
Order of draw is
essential in avoiding cross contamination from additives of one tube to the next
