It was developed in 1954 by Japanese medical laboratory scientist Dr. Katsuya Kato (1912–1991). [6] [7] The technique was modified for use in field studies in 1972 by a Brazilian team of researchers led by Brazilian parasitologist Naftale Katz (b.1940), [8] [9] and this modification was adopted by the WHO as a gold standard for multiple helminth infections.
[citation needed] The Kato technique (also called the Kato-Katz technique) is a laboratory method for preparing human stool samples prior to searching for parasite eggs. Eggs per gram is a laboratory test that determines the number of eggs per gram of feces in patients suspected of having a parasitological infection, such as schistosomiasis.
Merthiolate-Iodine-Formaldehyde (MIF) is a solution used in biomedical laboratories for concentration of stool samples prior to microscopic investigation for parasites. Concentration of stool is necessary in order to raise sensitivity of microscopy, as in non-concentrated samples the likelihood of finding equivalents of actually present ...
A stool test is a medical diagnostic technique that involves the collection and analysis of fecal matter. Microbial analysis (culturing), microscopy and chemical tests are among the tests performed on stool samples.
A stool ova and parasites exam reveals the presence of typical whipworm eggs. Typically, the Kato-Katz thick-smear technique is used for identification of the Trichuris trichiura eggs in the stool sample. Trichuria eggs often appear larger and more swollen on Kato-Katz preparation compared to when using other techniques. [18]
Entamoeba coli is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba histolytica.
