Aerobic or anaerobic microorganisms or bacterial spores. Enumeration on blood agar. (NMKL 189, 2nd ed. 2017)
This method is a routine method for the enumeration of
aerobic or anaerobic microorganisms on blood agar.
The method may also be used for the enumeration of bacterial
spores (spore count).
The method is applicable for monitoring bacteria in the
production or control of all kinds
of food, feed or water,
for instance mineral water.
It can also be used as a
supplementary analysis when investigating the causes of
suspected infections or poisoning through food or water.
The method does not replace aerobic plate count (NMKL
No. 86), but it may be used as a supplement. For instance
surface inoculation on blood agar may give valuable
information regarding the colony morphology.
