were used: A. Wet Mount Preparation – Direct Fecal Smear: Before preparing a wet mount slide‚ the microscope was calibrated. The objectives and oculars used for the calibration procedure were used for all measurements on the microscope. The calibration factors should always be posted on the side of the microscope. Using a wet mount identification technique‚ protozoan trophozoites‚ cysts‚ oocysts‚ and helminthes eggs and larvae may be seen and identified. In preparing a wet mount‚ a clean microscope

especially in hunting dogs‚ sporting breeds‚ and dogs that spend a lot of time in environments where the Blastomyces organism exists‚ but female dogs are also susceptible. This fungus is commonly found in decaying wood and soil‚ especially in places with a wet environment‚ like riverbanks‚ lakes‚ and swamps where damp soil lacking direct sunlight cultivates the growth of the fungus. It also thrives in areas that are rich in decaying matter‚ such as wooded areas‚ forests‚ and farms. The fungus is transmitted

Mount the specimen on the stage The cover slip must be up if there is one. High magnification objective lenses can’t focus through a thick glass slide; they must be brought close to the specimen‚ which is why coverslips are so thin. The stage may be equipped
