Conidia concentration is still mostly determined with the help of a hemocytometer; however, as a more accurate and time-saving alternative, absorbance can be used to estimate fungal spore counts.
WebAutoclave the medium components separate from the agar (in one half of the water) and mix after cooling to 65 degrees. You must do this to find the dilution factor which yielded your CFU count. This way you might be able to count at an earlier time point more accurately. The solution was serial diluted 10x (1/10).
Web22 Jan 2024 · WBC Count. When WBCs are counted, the calculation is much easier. WBCs are counted in the 4 corner squares of the main grid. These squares have an area of 1 mm2 each. To get the WBC count, the number of cells in each square are counted, and their mean is then calculated. Let the mean be ‘n’. The volume of each square is 1 x 0.1 = 0.1 mm3. aptima sabadellWebI had use haemocytometer count, but the number of spore were so abundance, hard to count and very time consuming.
