ABSTRACT
Soil Transmitted Helminths (STHs) are the most common Neglected Tropical Diseases (NTD) worldwide which remains a public health challenge and continues to cause significant morbidity and economic loss in Nigeria and in less developed tropical and subtropical countries. Globally, about 1.5 billion people are infected with at least one intestinal parasitic species. Dogs are of great importance in the spread of these parasitic species. The transmission of the parasitic diseases is accomplished through the environment contaminated with developmental stages of the helminths in dog feaces. The spread is defined by inadequate sanitation, poverty and unsafe water sources. The aim and objective of the study is to determine the prevalence of parasitic infections in dogs and its association with soil contamination in Ife- east local government area of Osun state. A total of 150 soil samples and 200 dog faecal samples will be collected. Soil samples will be taken from each of the sample points (playground, backyard, toilet area and refuse dump site). Soil and dog faecal sampling will be carried out in the morning between 6.00am and 11.00am.Approximately 100g of soil will be collected randomly at a depth of 2-3cm. Each sample will be placed inside a properly labeled polythene bag. In addition, using the applicator stick, dog faeces will be collected into a clean, labeled, properly covered sample bottles. Dog faecal samples will be immediately preserved with 2ml of 10% of formalin and transported to the laboratory in the Department of Zoology, Obafemi Awolowo University, Nigeria for examination and analysis. Both soil and fecal sample will be examined for helminths eggs with the use of centrifugal floatation technique using Zinc sulphate solution and Kato katz technique respectively. Then a microscopic examination. Correlation between rate of soil contamination and prevalence of dog intestinal helminths will be determined. Chi-square (χ2) test will be applied to assess the significant difference in each site of collection. All statistical analyses will be performed using SPSS vers
