COMPARING THE OCCURRENCE OF E. COLI IN BREEDING SITES LOCATED ON RURAL AND URBAN AREAS IN PLATEAU STATE

ABSTRACT

This study compared the occurrence of E. coli in breeding sites located on rural and urban areas in Plateau State, Nigeria, and assessed the influence of sanitation practices on bacterial occurrence. It also examined the statistical differences in contamination levels between rural and urban environments and analyzed the relationship between sanitation infrastructure and microbial presence. The study drew on relevant theoretical frameworks and empirical literature on environmental health and waterborne diseases. A cross-sectional design was adopted, with data collected from water, soil, and waste samples across 120 breeding sites (60 rural and 60 urban). Descriptive statistics, independent t-tests, and Pearson’s correlation analysis were used to analyze the data. Findings revealed that rural breeding sites had significantly higher E. coli contamination levels (water: 80%; soil: 60%; waste: 50%) compared to urban sites (water: 70%; soil: 50%; waste: 40%), with statistical confirmation (p < 0.05). The study also found a strong positive correlation (r = 0.65, p < 0.001) between poor sanitation practices (e.g., pit latrines) and E. coli occurrence in rural areas, while urban sites with flush toilets showed a weaker correlation (r = 0.30, p = 0.05). These results underscore the critical role of sanitation in microbial contamination and highlight the disproportionate risk faced by rural communities due to inadequate hygiene infrastructure. Based on these findings, the study concludes that improving sanitation facilities, enforcing waste management regulations, and implementing community-led hygiene education programs are essential for reducing E. coli contamination in Plateau State. It recommends targeted interventions in rural areas, including the upgrade of sanitation infrastructure and the integration of One Health approaches to address environmental, animal, and human health linkages. Policymakers should prioritize funding for rural sanitation projects, while public health campaigns should emphasize the adoption of improved hygiene practices to mitigate waterborne disease risks.

CHAPTER ONE

INTRODUCTION

Background of the Study

The presence and distribution of Escherichia coli (E. coli) in various environmental settings have become a growing concern in public health due to the bacterium's dual nature as both a harmless gut flora and a potential pathogen. While most strains of E. coli are non-pathogenic and play a role in maintaining intestinal health, certain strains such as Enteropathogenic E. coli (EPEC) and Shiga toxin-producing E. coli (STEC) can cause severe diseases including diarrhea, urinary tract infections, and hemolytic uremic syndrome (Russo & Johnson, 2022). These pathogenic strains often emerge in environments contaminated by fecal matter, making the occurrence of E. coli a reliable indicator of fecal pollution and overall environmental hygiene (WHO, 2023).

Environmental breeding sites—such as animal pens, water puddles, drains, refuse dumps, and poorly managed agricultural sites—are ideal habitats for the persistence and multiplication of E. coli. These sites vary significantly between rural and urban areas due to differences in land use, population density, sanitation infrastructure, and hygiene practices. In rural regions, open defecation, unregulated livestock movement, and limited access to potable water contribute to higher levels of environmental contamination (Adeyemi et al., 2021). Meanwhile, urban areas are not immune to microbial contamination, as overcrowding, poor waste disposal systems, and blocked drainage channels often create equally conducive environments for microbial survival (Eze et al., 2022).

Specifically in Plateau State, Nigeria, both rural and urban communities present distinct ecological and infrastructural features that may influence the occurrence of E. coli in breeding sites. Plateau State is characterized by its diverse topography and a population that is unevenly distributed across urban centers like Jos and rural areas such as Mangu and Riyom. Despite urbanization efforts, many communities still lack access to improved sanitation and effective waste management systems. According to the Nigeria Centre for Disease Control (NCDC, 2023), waterborne diseases such as typhoid fever and diarrhea—often linked to E. coli contamination—are among the most reported in the state, especially during the rainy season when runoff spreads contaminants from human and animal waste into communal water sources.

The difference in lifestyle and environmental management between rural and urban areas suggests that the prevalence of E. coli may differ significantly between these locations. In rural Plateau, livestock often roam freely, increasing the risk of contamination in water bodies and food sources. Additionally, many households rely on rivers, unprotected wells, and open reservoirs for drinking water, increasing their exposure to fecal bacteria (Olaniran et al., 2021). On the other hand, urban breeding sites like open drains, public toilets, and waste collection points are often overwhelmed by the sheer volume of waste, which may not be effectively treated or disposed of, leading to bacterial build-up and potential outbreaks (Obasi et al., 2022).

A comparative study of the occurrence of E. coli in these two contrasting environments within Plateau State is thus essential. It will not only identify the sources and hotspots of contamination but also provide evidence-based recommendations for improving environmental sanitation and reducing the public health burden associated with fecal contamination. Furthermore, such a study will contribute to ongoing discussions about sustainable development goals (SDG 6) related to clean water and sanitation, especially in under-resourced regions of Nigeria and other parts of sub-Saharan Africa.

In essence, the study aligns with global health priorities by addressing the need for localized, data-driven strategies in microbial monitoring. It provides a scientific basis for environmental and public health interventions targeted at both urban and rural communities, ultimately promoting a healthier and more resilient population in Plateau State.

Statement of the Problem

The occurrence of Escherichia coli (E. coli) in environmental breeding sites is a significant public health concern, particularly in areas where sanitation and hygiene practices are inadequate. This is particularly alarming in regions with a high prevalence of waterborne diseases linked to fecal contamination, such as Plateau State, Nigeria. Both rural and urban areas of Plateau State have reported numerous cases of gastrointestinal diseases, with E. coli being one of the primary pathogens detected in contaminated water sources, food, and environmental surfaces (Olokor et al., 2021). However, despite the growing concern over the presence of E. coli, there remains a limited understanding of how the occurrence of this bacterium varies between rural and urban breeding sites within the state.

Rural areas of Plateau State are often characterized by poor sanitation infrastructure, limited access to clean water, and practices such as open defecation and unregulated animal farming. These conditions create environments conducive to the spread of pathogens, including E. coli, which thrives in environments contaminated by fecal matter (Ilesanmi et al., 2022). In contrast, urban areas, while often benefiting from better sanitation services, still experience microbial contamination due to issues such as overcrowded settlements, inadequate waste management, and improperly disposed sewage. Consequently, breeding sites in urban areas, such as drainage systems, open dumpsites, and markets, may also serve as reservoirs for E. coli (Ayeni et al., 2020). Despite these risks, few studies have specifically compared the prevalence and distribution of E. coli in rural and urban breeding sites within Plateau State.

Moreover, the limited availability of local data on microbial contamination in rural and urban settings of Plateau State presents a major gap in the design of effective public health strategies. Understanding how E. coli varies in these areas is essential for prioritizing interventions and resources. Without clear insights into how contamination occurs and the factors that contribute to its spread in both environments, public health agencies may struggle to implement targeted sanitation programs, particularly in high-risk areas. Additionally, the lack of comprehensive data may delay the development of appropriate regulatory measures to address water and sanitation issues that directly impact the health of the population (Dairo et al., 2022). Therefore, this study aims to address the gap in knowledge by comparing the occurrence of E. coli in breeding sites located in rural and urban areas of Plateau State.

Significance of the Study

The significance of this study lies in its potential to provide critical insights into the environmental health risks associated with Escherichia coli (E. coli) contamination in breeding sites across rural and urban settings of Plateau State. The findings will serve as a valuable resource for public health authorities, environmental scientists, policymakers, and community stakeholders who are involved in disease prevention, sanitation improvement, and health education.

Firstly, public health officials and epidemiologists will benefit from a clearer understanding of the spatial distribution of E. coli in Plateau State. This knowledge will support better planning and implementation of disease surveillance systems, particularly in identifying high-risk zones where interventions such as health education, vaccination, or provision of clean water and sanitation facilities should be prioritized. By pinpointing the environmental and behavioral factors responsible for E. coli outbreaks, health workers will be better equipped to prevent and respond to potential disease outbreaks, thereby reducing the burden of waterborne illnesses in the state.

Secondly, government agencies and policymakers will find this study valuable for shaping effective environmental and public health policies. The study will offer data-driven evidence to support investment in rural and urban sanitation infrastructure, such as improved drainage systems, waste management services, and safe water supply. These insights will also help guide the allocation of resources in ways that are both equitable and impactful, addressing the unique challenges of rural underdevelopment and urban overcrowding.

Thirdly, environmental researchers and academics will benefit from the study’s comparative analysis, which adds to the existing body of knowledge on microbial contamination and environmental health in developing regions. The findings can serve as a foundation for further research into microbial ecology, public sanitation, and urban-rural health disparities, while also informing the curriculum in higher institutions that focus on public health, microbiology, and environmental science.

Furthermore, local communities and civil society organizations will be empowered through awareness of the health risks posed by poor sanitation and environmental practices. The study will highlight the importance of personal hygiene, safe waste disposal, and environmental cleanliness, which can inform health campaigns and community-led sanitation efforts. With this knowledge, community members can become active participants in promoting healthier living environments.

Finally, non-governmental organizations (NGOs) and international development partners working on health, water, and sanitation projects will be able to use the findings to design evidence-based programs tailored to the specific needs of Plateau State. The study will enhance the effectiveness of interventions aimed at achieving Sustainable Development Goal 6 — clean water and sanitation for all — especially in under-resourced communities.

Scope of the Study

This study was delimited to the comparison of the occurrence of Escherichia coli (E. coli) in breeding sites located in both rural and urban areas of Plateau State, Nigeria. It focused on identifying and analyzing the prevalence of E. coli in selected environmental breeding sites such as stagnant water bodies, open drains, refuse dumps, and animal waste accumulation points where the bacterium is most likely to thrive. The study covered specific rural and urban locations within Plateau State, allowing for a representative assessment of microbial contamination patterns across different settlement types.

The research concentrated on environmental sampling and laboratory analysis to detect the presence of E. coli in these sites. It also explored the relationship between sanitation practices, infrastructural conditions, and socio-economic factors in the study areas to determine how these variables influenced the occurrence and distribution of the bacterium. The scope included a comparison between urban areas with higher population densities and infrastructural development, and rural communities characterized by less access to modern sanitation facilities and water management systems.

Additionally, the study investigated the behavioral and hygiene practices of residents within proximity to the sampled breeding sites to understand how human activities may have contributed to the contamination levels. However, the study did not extend to clinical diagnosis of E. coli-related infections in individuals, nor did it cover the genetic characterization of the E. coli strains identified.
