Counting chambers
  • Focus on the gridlines in the chamber which are on the underside of the top slide
  • Use the 4X objective lens first and then change to the 10X
  • It should then be possible to see a line of each grid on each side of your field of view
  • Strongylid eggs are about the same length as the gridlines are wide (donít confuse with coccidial oocysts
  • Count the number of strongylid eggs in each chamber, add them together and multiply by 50 to give you a count of egg per gram of feces
