Variations in the Rate of Infestations of Dogs with Zoonotic Nematodes and the Contamination of Soil in Different Environments

Abstract

Companion animals are an important aspect in human life. However, they may also be considered a source of pathogens. An example of zoonotic parasitoses is toxocarosis or cutaneous larva migrans (CLM). The aim of the study was to detect zoonotic nematodes of dogs living in different areas and the intensity of contamination in parasite polluted environments that are hazardous to human health. The fecal samples were examined using standard flotation and decantation methods as well as McMaster’s quantitative technique. The soil samples in urban and rural areas were examined using a modified flotation method as described by Quinn et al. Statistical analyses were performed by IBM SPSS Statistics Version 23. The overall prevalence of parasites in dogs was 38%, 17.02% and 56.60% from urban and rural areas, respectively. The percentage values of nematodes important for human health (Toxocara canis, Ancylostomatidae, Trichuris vulpis) remained at the same level (16%). The infected dogs were dominated by a single parasite species, the main was T. canis (28.95%). In total, 54.30% of the soil samples were contaminated with parasite eggs. The contamination of urban and rural sandpits was 40% and 60%, respectively. The molecular examinations of soil samples using LAMP (loop-mediated isothermal amplification) confirmed the presence of nematode eggs of the species T. canis in all samples previously classified as positive

Determining the occurrence of the Uncinaria stenocephala and Ancylostoma caninum nematode invasion in dogs in Poland, with special emphasis on the Lublin region

“…Na terenie Lubelszczyzny prowadzono badania dotyczące inwazji tęgoryjców u psów oraz zanieczyszczenia gleby jajami tych pasożytów, jednak opisywane były one łącznie, bez różnicowania gatunkowego (6,30,59). Analizę morfometryczną jaj tęgoryjców z terenu Lubelszczyzny przedstawiono w tab.…”

Legal aspects associated with the lack of possibilities of preventing the spread of toxocarosis and toxoplasmosis in Poland

“…Currently, the municipal authorities must, by March 31st, adopt an annual program for the care of homeless animals and the prevention The authors of the publication draw attention to the diversity of threats, not only between countries and cities, but even between nearby areas. 3,5,7,17,19,30,31,33,37,44 In the light of the above, changes to the Polish law in the field of public health protection, which have occurred in recent years, are very questionable. The removal of diseases with dangerous and irreversible effects to human health and life from the list of infectious diseases defies logical explanation.…”

“…Source of zoonosis are the sick and infected animals that have direct contact with humans as well as animals which constitute a source of food for people [1][2][3][4][5][6][7][8][9][10][11][12]. The development of civilization does not always limit incidents of contagion with a disease, which could not be eliminated even in developed countries [14,[13][14][15][16][17][18][19][20].…”
