NOTAS SÔBRE MODIFICAÇõES DO "MIFC" NA CONSERVAÇÃO DE FEZES PARA PESQUISA DE CISTOS DE PROTOZOÁRIOS

Abstract

The Author studies the techniques o f the "MIFC" (merthiolate-iodumformalin) commended in the preservation and coloration o f the feces for research on helminth's eggs and cistus of intestinal protozoa. Introduces some modifications, substituting the tincture of merthiolate at the r ate o f 1 : 1000 by that o f the mercury-chrome at 2: 1000 and commends the employment of lugol after the preparation of the material to be examined. Verifies that, by studying comparativcly both the duly modified "MIFC" and the "Faust", thc results, obtained among 200 (two hundred) examens carried out, show that the two methods are equivalent in the practice. Accentuates also that the material preserved in the solution of mercury-chrome formalin is apto be looked into under the usual tecniques of enrichment. Considers that the modified "MIFC" is of large use in the coprological inquiries in the rural area.
