differential of >80% is highly suggestive for chronic infection about a THA [16]. Additionally‚ the onset of symptoms in relation to the primary operation can help identify the causative organism. Early (12 months) infections are commonly due to staphylococcus aureus‚ while delayed (3 to 12 months) infections are commonly due to propionibacterium species [17-19]. In an effort to increase diagnostic yield and decrease false-negative cultures‚ patients should stop antibiotics for a minimum of 2 weeks prior

CHAPTER ONE INTRODUCTION The industrial attachment is an important part of the course structure of the university. This is the time students appreciate the theoretical work done in the lecture halls when seen practically. This attachment introduces the student to the outside world in terms of working experience and also prepares them for the future. The department of applied biology therefore introduced the industrial attachment program in its learning curriculum to give students a chance to combine
