Contamination of Soil and Vegetation with Developmental Forms of Parasites in the Area of the Federation of Bosnia and Herzegovina

Abstract

Abstract Background: According to the WHO (2019), more than 1.5 billion people worldwide are infected with soil-transmitted parasites. Previous research in the Federation of Bosnia and Herzegovina (FB&H) was mainly conducted in the area of the Sarajevo Canton. Therefore, the aim of the research was to explore contamination of soil and vegetation with developmental forms of parasites in the other cantons of FB&H. Methods: Between Apr and Oct 2018, a total of 1,618 soil and vegetation samples were taken from 386 different locations in the 9 cantons of the FB&H. Results: Positive samples were observed, 65/66 (98.48%) municipalities/cities and on 239/386 (61.92%) locations. Out of 1,618 samples taken in total (1,263 soil samples and 355 vegetation samples), 357 (22.06%) were positive, out of which 337 (26.68%) and 20 (5.63%) were soil and plant samples, respectively. In total, the following adult and developmental forms were identified: Taeniidae eggs (7.30%), Toxocara spp. eggs (62.08%), Ancylostomatidae eggs (25.00%), Trichuris spp. eggs (9.55%), Capillaria spp. eggs (3.37%), Toxascaris leonina eggs (1.40%), Nematodes larvae (19.38%), Giardia duodenalis cysts (5.06%), Cryptosporidium spp. oocysts (1.4%), oocysts and cysts of different species of Protozoa (3.93%). Conclusion: The identified developmental forms of parasites pose a permanent threat to human health. It is necessary to carry out measures to reduce the contamination of soil and vegetation in coordination with systematic solutions (legislation), paralelly with contribution of animal owners, veterinarians, physicians, ecologists, parents and all the others involved in this issue.
