Abstract

This laboratory-based project isolates and identifies bacteria from street-vended food samples and determines their antibiotic susceptibility patterns. Using standard culture, biochemical tests and the Kirby-Bauer disc diffusion method, it profiles resistance to commonly used antibiotics and discusses the public health implications of informal food vending. The study is organised into five chapters covering the introduction, review of related literature, research methodology, data presentation and analysis, and the summary, conclusion and recommendations.

Chapter One: Introduction

1.1 Background to the Study

This laboratory-based project isolates and identifies bacteria from street-vended food samples and determines their antibiotic susceptibility patterns. Using standard culture, biochemical tests and the Kirby-Bauer disc diffusion method, it profiles resistance to commonly used antibiotics and discusses the public health implications of informal food vending.

1.2 Statement of the Problem

Laboratory study of antibiotic resistance in bacteria isolated from street-vended foods. Existing approaches remain limited in reach, accuracy and ease of use, which creates the gap this study addresses.

1.3 Aim and Objectives

The aim of this study is to antibiotic resistance patterns of bacteria isolated from street-vended foods. The specific objectives are to:

  1. review existing literature and systems related to the study;
  2. collect and analyse data using Laboratory experiment;
  3. evaluate the results against the stated problem;
  4. make recommendations for practice and further research.

1.4 Scope of the Study

Introduction: background to antibiotic resistance in street foods, statement of the problem (street-vended foods are a suspected vehicle for resistant bacterial strains but local data is scarce), aim and objectives, research questions, scope, significance of the study, and definition of terms.

Chapter Two: Literature Review

Literature Review: theoretical framework, review of related works on antibiotic resistance in street foods, gaps in existing studies, and a summary positioning this project. Literature Review: theoretical framework, review of related works on antibiotic resistance in street foods, gaps in existing studies, and a summary positioning this project.
