The disadvantages/limitation of the breed count method are as follows: Both viable and non-viable cells are counted as there is no effective way to differentiate between the two, A suspension may contain a very high number of cells which makes this technique difficult, As high magnification is required to visualize the bacteria, it limits the volume of liquid that can be examined, Some bacterial cells are very small and thus are missed/overlooked, The precision of this depends highly on the experience of the microbiologist as some cells can be missed while manually counting, This method is tedious and not suitable in cases of suspensions with low density of microbial cells. Adaptability and heat tolerance. 1. Explain the concept of grading up, as it relates to commercial Mate the 1/2 pure cattle to 100% purebred members of Breed A.

The procedure for breed count method involves following steps: Place the stage micrometer on the microscope's stage and observe it under oil immersion with a sharp focus, Count the number of divisions in the stage micrometer visible under one microscopic field, Determine the radius and area of 1 microscopic field using the formula given above, * If the diameter of 1 microscopic field = 13 divs of the stage micrometer, * Each division of stage micrometer = 0.01mm, Diameter of microscopic field = 13 x 0.01 mm = 0.13 mm, Radius of microscopic field = diameter/2 = 0.13/2 = 0.06mm, Area of one microscopic field = r2 = 3.14 x 0.062 = 0.01 mm2, Take a clean, sterile 1cm2 engraved glass slide, Using a sterile calibrated loop or pipette, make a uniform smear within the marked area, Air dry and heat fix the test microbial smear, Use simple staining using methylene blue and observe the slide under the microscope, Get concurrent readings on Wilson's chart, Calculate the number of microorganisms per ml of sample, * If the area of one microscopic field = 0.01 mm2, No.
