________________________________________________________________________ Note 1. Zinc sulfate in available from Anachemia (No 98440-380; Price: 80$ for 2 kg) or from other suppliers. Add 450 g of zinc sulfate to a litre of distilled water and shake it until dissolve. Also, FECADRY II can be obtained from CDMV (No 14496; Price: 19$ for 3.8 litres). Note 2. If you use a horizontal centrifuge, you can skip step 3 by filling the tube in such a way to obtain a positive meniscus and placing a cover slip on top of the tube. After the tubes are properly balanced, they can be centrifuged. Table 18. Comparaison of prevalence rates obtained by necropsy and by zinc sulfate flotation in 2,737 dogs and 1,480 cats at a New-Jersey shelter (Lillis, 1967) Species Prevalence (%) Sensibility (%) Nécropsie Flottation Dogs Ancylostoma 72 63 87,5 Toxocara 22 11 50,0 Cats Trichuris 75 65 86,6 Taenia 25 15 60,0 Dipylidium 28 1 3,5 Toxocara 55 45 81,8 Taenia 33 19 57,5 Dipylidium 10 0 0 This study used flotation, which is less sensitive than centrifugation, as the fecal examination technique. However, because of the very high prevalence, the parasite loads were probably high as well. Nowadays, the low prevalence rates observed certainly does not account for such high sensitivity. On the other hand, parasites, at least certain species, are considered prolific, which gives us some assurance with regard to sensitivity. Table 19.
