title: Improvement of the merthiolate-iodine-formalin (MIF) fecal technique for hookworm, Trichuris trichiura, and Ascaris lumbricoides eggs.
abstract: The merthiolate-iodine-formalin (MIF) technique to detect human intestinal parasites in feces was inefficient for the detection of hookworm and Trichuris trichiura eggs. Addition of a saturated-brine flotation step increased recovery of hookworm eggs by 77% and Trichuris trichiura eggs by 87%. Recovery of Ascaris lumbricoides also was increased by 71%. This was a significant improvement in the sensitivity of the MIF technique for these 3 kinds of human parasite.
