Approximately two gram faecal sample was mixed with 30ml of flotation solution (Sheathers sugar flotation solution: 450g Sucrose sugar in 355 ml distilled water with 6ml of 40% formaldehyde/Sodium nitrate flotation solution: 315 g Sodium nitrate in 100ml distilled water with specific gravity 1.2-1.25) in a 150ml waxed paper cup and agitated throughly to make an emulsion.
Es importante mencionar, que a pesar de que las muestras de heces no fueron sometidas a esporulacion con Dicromato de potasio al 2 % (Sloss, Kemp, & Zajac, 1994; Foreyt, 2001), algunos coccidios se detectaron esporulados cuando las heces fueron procesadas por la tecnica Sheather. Los coccidios identificados en este estudio fueron Isospora spp.
Demonstration of intestinal infections in the immunosuppressed patients employing concentration method such as Sheather's sugar floatation technique and formol-ether concentration method are found to be essentially effective in our study.

La separacion de los huevos del Toxocara sp se realizo mediante centrifugacion/floculacion utilizando las siguientes soluciones: MgS[O.sub.4] (r = 1,2 g/mL), ZnS[O.sub.4] (r = 1,18 g/mL), NaCl (r = 1,18 g/mL) y solucion modificada de Sheather (azucar granulada, agua destilada y 1% de formaldehido) (r = 1,27 g/mL).

We used a Gaussian kernel function (Silverman 1986, Chen 1996a) and the direct plug-in bandwidth selection method (Sheather and Jones 1991, Wand and Jones 1995, Sheather 2004) to develop the detection function for groups.
