ENY-167: How to Quantify Nosema Spores Infection Rate in a Honey Bee Colony

Figure 2. A single-use dropper is being used to load the sample into the lower chamber of the hemocytometer. A droplet of the sample is placed in the loading cavity at the bottom center of the hemocytometer (a triangular groove), and capillary action pulls the liquid up into the viewing grid. This hemocytometer has two viewing grids, and the top grid has already been loaded.
