Análise comparativa entre diferentes técnicas para detecção de parasitos zoonóticos em amostras vegetais e de solo

Abstract

Public areas such as parks, beaches and fairs are of great importance to cities, as they add economic, environmental and social benefits. In these places, cats and other animals are often represented in the spaces, which can often be a public health problem. In this, the knowledge of the degree of importance of the soil and food context is as epidemiological purposes. In this way, the risk of exposure to frequent locations can be determined and data provided to the management establishments at these locations. Therefore, the aim of this study was to analyze the FLOTAC technique in the detection of zoonotic parasites in soil and vegetables and compare it with the Spontaneous Sedimentation and Centrifuge-sedimentation techniques.For this, 300 samples of lettuce (Lactuca sativa) and 300 soil samples were analyzed and compared by the techniques proposed above. All the techniques used in this study were ableto detect parasite larvae both in vegetables and in the soil of recreational areas. Being the mosteffective FLOTAC technique in this detection. The main parasites recovered belonged to the Ascarididae, Ancylostomatidae and Trichuridae families. For the purpose of comparison between the techniques, the kappa index was determined, and values of sensitivity, specificity, positive and negative predictive values and precision were also calculated. This study is the first report of the use of the FLOTAC technique for the detection of parasites in soil and vegetables. In view of the results obtained, the FLOTAC technique was more appropriate than the other techniques.
