Other parasitic forms were found by both techniques. F/EA plus trichrome
staining recovered 126 (17.9%) specimens with Giardia lamblia, whereas SSF recovered only 42 (6.0%)specimens with G. lamblia. No association (X2 = 0.02, P = 0.89) was observed between the presence of G.lamblia and Cryptosporidium sp. in these stool specimens.
