Assessment of Kato Method in the Diagnosis and Counting of Helminth Eggs

Abstract

This study investigated the value of the KATO method in the diagnosis and enumeration of helminth eggs in HZ-AC/SA. Helminthiases are widespread disease worldwide and are among the most common conditions constituting a public health problem. It is a fact that most biomedical laboratories limit themselves to direct examination in the search for these parasites. This study lasted three months from May to August 2020 and took place at Abomey-Calavi/Sô-Ava Area Hospital Laboratory. For this purpose 106 stool samples collected from patients received at the laboratory of Abomey-Calavi zone hospital and Zinvié health center for coprological diagnosis were analyzed. At the end of the tests, 06.61% of the stools were positive. Ascariasis came first with 85.71% followed by hookworm with 14.29%. The study showed that only children are infested and the diagnosed parasites are only found by the KATO method. This method is effective in the diagnosis and counting of helminth eggs. The KATO method allows not only the detection of parasites but also their quantification, hence its interest in the diagnosis and counting of helminth eggs. Given the importance of this method, it would be desirable to associate it with parasite diagnosis in order to increase the chance of finding helminth eggs even if they are rare.
