Default Counting bacteria



What is the fastest way to get direct counts of bacteria? Plating and
turbidity measurements are probably not the way to go but if there is
an easy way, that would be fine.

Given the restrictions you have put on the process, about all that is
reasonably left is direct microscopic counting. Using a Petroff-Hauser
counting slide according to the instructions will give you quite
accurate counts, although you cannot differentiate between viable and
non-viable cells.

Default [Microbiology] Counting bacteria

Dear Maria

Not sure why you exclude plate counts as these can now be done quickly and accurately using digital camera plate counters. The impprovements in images allows the use of a wide range of agar so can differentiate between mixed cultures.
