Contribuição ao acervo da disciplina de Parasitologia Clínica do ICBS – UFAL: proposta de transformação de lâminas temporárias pela técnica de Kato-Katz, em lâminas permanentes

Abstract

The Kato-katz method is considered by World Health Organization (WHO) as the best technique for the diagnosis of infections by Schistosoma mansoni. It is considered a tool of clinical and epidemiological relevance because it allows to classify the parasitic load of the infected, through the calculation of eggs per gram of feces. This classification can also be used to estimate the intensity of infections in differents places. The state of Alagoas has more of 70 endemic city to schistosomiasis and the achievement and reading of technique of kato-katz is part of the content of parasitology clinical discipline. However, the technique doesn’t allow the visualization of eggs for long time, due to the slide drying around months. The purpose of the modified technique is to increase the number of slides in the Parasitology collection, allowing classes to always have the parasite visualization and its method available. For this, it obeyed the following methodology: removal of the cellophane cover slide, application of a drop of Xylol and a drop of Entellan followed by the addition of a glass slide. In these perspectives, by increasing the durability of the slides, future classes will have access to the material with the same condition allowing the quality of teaching in the practical classes of the Clinical Parasitology discipline, offered by the Parasitology Sector of ICBS-UFAL.
