Helmintoses zoonóticas transmitidas pelo consumo inadequado de peixes

Among the major food-borne parasitic zoonoses, the helminthiasis transmitted by consumption of fish have been highlighted because they involve a large number of individuals in many regions of the world in recent years. In the past, these parasitosis were restricted to underdeveloped nations or with peculiar eating habits; however the process of globalization of food production, the increased international travel and consumption of fish for their nutritional benefits caused the expansion into new areas, which had never before been recorded, making it a serious public health problem in some countries. This review discuss the main helminths transmitted by eating raw or undercooked fish, in order to alert the public, the scientific community and health authorities about their risks to human health, as well as stimulate the realization of new researches that contributes to a greater knowledge of the epidemiological situation in the country of these parasites and the development of strategies for prevention and control of them.

TF-Test modified: new diagnostic tool for human enteroparasitosis

Intestinal parasitosis is highly prevalent worldwide, being among the main causes of illness and death in humans. Currently, laboratory diagnosis of the intestinal parasites is accomplished through manual technical procedures, mostly developed decades ago, which justifies the development of more sensitive and practical techniques. Therefore, the main objective of this study was to develop, evaluate, and validate a new parasitological technique referred to as TF-Test Modified, in comparison to three conventional parasitological techniques: TF-Test Conventional; Rugai, Mattos & Brisola; and Helm Test/Kato-Katz. For this realization, we collected stool samples from 457 volunteers located in endemic areas of Campinas, São Paulo, Brazil, and statistically compared the techniques. Intestinal protozoa and helminths were detected qualitatively in 42.23% (193/457) of the volunteers by TF-Test Modified technique, against 36.76% (168/457) by TF-Test Conventional, 5.03% (23/457) by Helm Test/Kato-Katz, and 4.16% (19/457) by Rugai, Mattos & Brisola. Furthermore, the new technique presented “almost perfect kappa” agreement in all evaluated parameters with 95% (P < 0.05) of estimation. The current study showed that the TF-Test Modified technique can be comprehensively used in the diagnosis of intestinal protozoa and helminths, and its greater diagnostic sensitivity should help improving the quality of laboratory diagnosis, population surveys, and control of intestinal parasites.
